Self-consumption in Barcelona, ​​what does the future hold?

Image result for soty solarSotySolar, a leading company in the selfconsumption sector, which has several reference studies on the current situation of self-consumption in Spain, has prepared a new study in which it discusses the situation of self-consumption in the province of Barcelona.

Let’s repeat it once more, if necessary, self-consumption is here to stay. It is legal and very profitable, since costs have been reduced by more than 76.5% in this decade.

 

Self-consumption situation in Barcelona

Image result for barcelona solar

In Barcelona, ​​a total of 433 kW have been installed so far in 2018 , representing 15% of the total installed power in Barcelona. This represents a growth of 35% compared to the same period of the previous year. In other words, in August 2018 the same power will be installed as during the previous year.

This translates into 94 new self-consumption facilities in Barcelona , of which 118 kW have been for the industrial sector, 120 kW of commercial use, and the palm is carried by the residential sector with 195 kW installed and distributed in 71 facilities.

Barcelona has installed 60% of the installed capacity throughout Catalonia. Another data of special interest is the distribution of self-consumption within the different localities of the Catalan province. There is at least one self-consumption facility in 48 municipalities of the 311 that make up the province of Barcelona. In absolute terms and as is logical by population volume, Barcelona is the city with the most kW of solar energy installed with a total of 520 kW. However, if we refer to the Installed Power / Hab ratio, the first place is occupied by the town of Castellcir with 80.14 w / hab followed by Sant Mateu de Bages with 64.28 w / hab.

In the first place, it is convenient to indicate that when we talk about installed power (MW) we refer to solar panel installations in Barcelona that have been duly legalized in the administrative record of self-consumption of electric energy of the Ministry of Energy, Tourism and Digital Agenda.

“It has been surprising to see that the domestic sector is the fastest growing sector. In the first phases of development, the natural thing is that self-consumption is implemented mainly at the business level. That Barcelona is not like that, reveals that Catalan society is one step ahead. He has become aware and is betting vigorously on the renewable energy transition through self-consumption with solar panels in Barcelona “says Edgar Imaz, co-founder of SotySolar and the author of the study.

 

Who install solar panels in Barcelona?

A more appropriate question would be, Who are the solar energy enthusiasts? We will make two distinctions: on the one hand, the owner of a single-family home and on the other the manager of a typical company:

What is the profile of solar energy companies in Barcelona?

There are many solar energy companies in Barcelona of different sizes, with different portfolio of services, but if we were to characterize the profile of solar energy companies in Barcelona, ​​it would be the following:

The role of public bodies

Speaking of Barcelona is talking about one of the most cosmopolitan cities and also one of the most developed provinces in the European Union. Barcelona and its citizens have decided to be sustainable. The following 3 cases illustrate this situation:

  • Barcelona City Council confirms its commitment to Solar Self-consumption, allocating € 12.4 million during the period 2017-2019.
  • Barcelona Energía, the green marketing company of the Barcelona City Council, creates rates specially designed to encourage self-consumption.
  • Many town councils include bonuses in the IBI, ICIO and IAE for the installation of self-consumption systems of renewable generation. At this point, the town of Rubí stands out, where through the Local Economic Development Area they have developed the so-called “green taxation” with tax rebates on the three main municipal taxes.

 

The future is ours

All the studies point towards the same direction, one in which self-consumption will be part of our day to day life and no homes will be conceived without their own system of energy generation with smart batteries , as they are not conceived now without a fridge, washing machine and Full HD flat TV. By combining installations of solar panels in Barcelona with solar tariffs, average savings of around 40% in the electricity bill are being achieved, this shows what the guidelines to follow in the immediate future may be.
Returning to Barcelona, ​​reports from reputable consultants estimate that photovoltaic technology could reach 178 thousand homes by 2021 in a realistic scenario. This will involve the installation of 476 new MW, which will generate 6500 jobs and stop producing 100 tons of CO2.
Finally, Edgar Imaz, responsible for the study, points to the end of the energy model as we know it, and is committed to a system in which the citizen produces and consumes his own energy in a responsible, efficient and respectful way with the environment .

Why do not you see more roofs with solar panels for self-consumption?

¿Por qué no se ven más tejados con placas solares para autoconsumo?

Most citizens would like to save money on the electricity bill and be able to generate green energy in our own homes to consume it directly. So, why do not you see more roofs with solar panels for self-consumption? The answer lies in misinformation , on the one hand, and confusing information , on the other. With this entry we will try to throw a little light on all this “tinglado” and, thus, encourage many citizens to bet on self-consumption.

Self-consumption and storage are legal in Spain

 

The sun tax affects only those self-consumption facilities that exceed 10 kW. This means that only 2% of Spaniards are affected , 98% of households would not be obliged to pay the sun tax . However, the installations of solar panels have fallen since the incorporation of the regulation that includes this tax. This is because in addition to the tax, the law puts a series of difficulties and great bureaucracy that make it difficult to decide. Among them we find the amount of papers that must be completed: technical report, application for connection permits to the company, have a line and a specific automatic, pay connection fees and hook, install a second counter along with the one that already has the housing, etc. Calm down, at SotySolar we do all this for you!

All this, supposes a cost, economic and in time, of which the majority of the Spaniards does not have. Therefore, despite the fact that the price of electricity has risen around 70% in the last 10 years, we did not decide to install solar panels for self-consumption.

You could say that in Spain is sanctioned for doing the right thing, instead of facilitating the installation of solar panels in homes and take advantage of an abundant resource in Spain, the sun, there are impediments for it. Citizens are aware, and most of them would like a change in energy production towards a more renewable and sustainable way, but not only are they not helped to carry it out, but impediments are placed on it.

What happens if we install solar panels and generate energy that we do not consume?

Image result for solar panelIf we generate surplus energy in our installation of solar panels for self-consumption, we have 3 options: to waste it, sell it or store it in batteries . In the first case, it is not logical to think that while some households can not afford to pay the bills of light, in other homes, energy is thrown away. The second option, to sell this energy , that is to say, that the company makes a net balance , seems the most logical, since you would get some income and it would be taking advantage of it, but again we go back to the bureaucracy, the amount of papers that must be done to allow you to sell it (you have to register in some registers, etc.) makes it unprofitable, since the sale will not be a high income. The last option, the use of smart batteries , is being applied in some homes, even if they have completely disconnected from the network. At night they take advantage of the energy generated by the solar panels during the day and that they have not used. These batteries , today, increase the cost of the initial investment, take up a lot of space, and are not very ecological, although they are still being developed and these inconveniences may disappear in the future.

 

Spain stopped betting on renewables, but what have other countries done?

 

A photovoltaic panel in Spain provides 49% more energy than one in northern Europe thanks to the climate. Most developed countries are committed to self-consume electricity, without going further, in Portugal the regulation favors it, for small self-consumption facilities you just have to register on a website. Although Europe enjoys its holidays in Spain by the sun, in solar self-consumption facilities we are behind Italy, France, United Kingdom and Germany. The installed power in Germany is 8 times that of Spain, since the government promotes the installation of solar panels in homes , for example. Of the 100 GW installed in Europe, only 5% corresponds to Spain.

To make clear how the legislation has affected self-consumption, in 2008 Spain was the world leader in installed power in photovoltaics, however, cuts to renewables (the first in 2010 and the second and strongest in 2011) have reversed this situation now Spain is a very small target for photovoltaic solar energy companies. Most have disappeared or left Spain. As an example, in 2015 the United Kingdom, a country characterized by its cloudy days, installed in the order of 3500 kW, while Spain, where sunny days abound, only 49 kW.

Shared self-consumption is already possible

Image result for sharedBut not everything is bad news. Recently, the Constitutional Court has annulled the government’s prohibition on shared self-consumption . The TC gives the reason to the Generalitat de Catalunya that filed an appeal against the Royal Decree for invasion of autonomous powers. The prohibition affected neighboring communities, preventing them from sharing self-consumption generation facilities.

 

The photovoltaic is profitable by itself , does not need subsidies, only that citizens have the initiative to install solar panels . From the legal side, obstacles and paperwork existing today we take care of ourselves.

Tesla, where are we going?

Image result for tesla logoA few months after the expected Tesla Model 3 sees the light, the expectation can not be greater, and that is that we are facing the third step of the Master Plan prepared by the Californian company to revolutionize the way we understand the generation and consumption of Energy.

The beginnings of Tesla

<strong>The beginnings of Tesla</strong>

It was in 2003 when Elon Musk, Martin Eberhard, JB Straubel and Marc Tarpenning decided to join forces to create an electric car that was efficient and attractive to the consumer, that is how the Tesla Roadster emerged, the first model of the company that deserved all kinds of international recognition, and opened a path of no return for the development of a sustainable transport model.

The success of his first electric car was followed by the Tesla Model S and the Model X, which sought to increase manufacturing volume and reduce the market price, with the idea of ​​making vehicles environmentally friendly accessible for all pockets, idea is now reaffirmed with the upcoming release of the Tesla Model 3 with an estimated cost of about € 30,000.  

This is completed with a network of free superchargers that will pass this year from 5,000 to more than 10,000 units spread around the world, without going over Spain, which currently has 10 charging points, it is expected to be 24 by the end of this 2017. In this way, Tesla wants to facilitate the access to the load to its users and give confidence to this aspect to their potential clients.

Powerwall and Powerpack

<strong>Powerwall and Powerpack</strong>

But, alas! Tesla is not just Motors , the American giant presented its two energy storage systems in the spring of 2015: Powerwall and Powerpack. The first one is designed for the consumer with a capacity of up to 10 kWh and with the possibility of connecting up to 9 units, while the Powerpack is designed for renewable energy generation plants.

At the end of last year saw the light of the second version of both solutions with greater capabilities and new implementations. Tesla’s intention seems to be to make their two batteries work together, which they have called aggregation, and which has the main objective of benefiting both the power plants that have a Powerpack and the consumers who own the Powerwall.

 

Solar tiles

<strong>Solar tiles</strong>

Not content with this, in the autumn of 2016 Tesla began a merger process with the company SolarCity, dedicated to the installation of solar panels. With this new relationship was intended to shape the new flagship product of the American company: Solar Roof . A solar roof that will be available this summer in the United States and during 2018 for the rest of the world. The expectations with Solar Roof are very high, and the data that are known encouraging, with lifetime guarantees for tiles and 30 years for generation and weathering, surprisingly the cost of installing this roof would be below that of a traditional roof .

To carry out its ambitious project, the American company has a gigafactory in the state of Nevada, which is intended to work at full capacity in 2020. But the thing does not end there, recently Elon Musk has announced the construction of at least 10 gigafactories that could be 20 at best. As expected, speculation has been unleashed and everything seems to indicate that Europe will be the next destination of the Silicon Valley company, where Vaasa (Finland) surpasses its multiple competitors because it is Tesla’s new headquarters in Europe, even though it is not There is nothing decided and other countries such as the Czech Republic, France, Spain … could opt for a second European gigafactoría.

As for the expansion plans in the Asian continent, China is the number one objective of the manufacturer and it is probably where the third factory is installed after the American and the European.

 

What can we expect?

The world of energy in general and renewable energies in particular have to be attentive to the movements of Tesla, a company that was born with the intention of changing our way of understanding energy consumption and that step by step has been making room between the large multinationals, their products seem to be aimed at breaking down barriers and revolutionizing our concepts.

Musk has the goal of improving our planet and facilitating our life in it, Tesla can be the spearhead of a change in the energy model that is as necessary as it is unstoppable. Let’s hope that governments are up to the task. moment that seems decisive for the future of the world as we know it.

 

5 keys of thermal solar panels

What is solar thermal energy?

What is solar thermal energy?

Solar thermal energy is nothing more than capturing the heat of the sun through the use of solar panels , to take advantage of our day to day.

Being the country of the Sun makes this type of energy crucial for our present and future energy development.

What is the use of thermal solar panels?

The uses of solar thermal energy are increasingly wide, but in terms of residential and business use, the production of domestic hot water takes the cake.

We must also highlight its good results in air conditioning systems, both for heating and cooling, with the well-known “solar cold”. Another very recurrent application of this type of facility is the pool heating .

How do the installations of thermal solar panels work?

How do the installations of thermal solar panels work?

Thermal solar panels are responsible for capturing the heat of the Sun, through them circulates a fluid, usually water, which is heated and stored in a drum that acts as an accumulator.

The water stays warm in this thermally insulated tank for later use, Yes! Even at night. However, it must be borne in mind that these facilities need an auxiliary system for possible periods of cloudy days.

Why put solar thermal plates?

The advantages of opting for a green energy source are innumerable, but next we will highlight some of the most important ones:

  • We do not need fuel, so the economic savings are considerable.
  • It protects us against the continuous rises of light and gas.
  • We stop emitting greenhouse gases, we contribute to curb climate change.
  • Our home will increase its value, our company will improve its public image.
  • We generate employment, we boost the economy and we reduce the energy dependence of our country with respect to third parties.

What is the price of thermal solar panels?

Well this is the million dollar question, it is impossible to give a price of solar panels that is valid for all facilities, since the final cost is influenced by various factors, such as location, technical characteristics, consumption habits …

Having said that, a price that we can expect is around € 1,000 to € 1,500 per m² of panels, we must bear in mind that these are installations with a useful life of more than 20 years.

Likewise, the savings that an installation of solar panels entails are around 70% of our consumption, which results in investment returns close to 5 years.

conclusion

Solar thermal energy is a mature, clean and profitable technology. This makes it a very important option to take into account to cover the energy needs of our home or our company.

We are facing a momentous moment to mark the course of our energy future and betting on green energy is to bet on insurance.

What are photovoltaic inverters?

 Solar panels are not the only component that we must take into account when planning a solar energy installation. The photovoltaic inverters They play an equally important role, since they convert the electricity generated by the solar panels so that they can use the appliances, lighting and other electronic devices that we have at home.

Now we will try to understand how investors work and the different types that we can find in the market.

How do photovoltaic inverters work?

<strong>How do photovoltaic inverters work?</strong>

When our photovoltaic panels receive sunlight, the electrons begin to move inside the solar cells, which produces electricity from direct current. The circuits inside the photovoltaic cells collect that energy for us to use in our house.

This is where the solar inverter comes into play. Most homes use AC electricity, not direct current, so the energy produced by the solar panels is not useful by itself.

When solar panels collect sunlight and convert it into energy, it is sent to the inverter, which receives electricity from direct current and converts it into alternating current.

That is when solar electricity can power the appliances and electronic devices or, if we are producing more electricity than we need, store it in batteries or we could pour it into the electricity grid.

Main functions of the Photovoltaic Inverter

  1. Energy conversion : The photovoltaic solar inverter converts direct current into alternating current, which is the one used by all electrical appliances. It basically acts as a gateway between direct current and alternating current.
  2. Optimization of energy : Maximizes the generation of energy from solar panels. To do this, the panels are individually insulated in order to increase the production of energy, and therefore, improve the overall performance of the installation.
  3. Monitoring and protection : A solar inverter monitors the energy performance of the photovoltaic system, the electrical activity and signals when problems arise. This information can be viewed on the device itself or from another location if the appropriate communication technology and online services are implemented.
  4. Constant operation : A photovoltaic installation is designed to provide power to the weather and in all weather conditions. The photovoltaic inverter offers a constant operation dissipating the heat in a consistent way.

Types of Photovoltaic Investors

<strong>Types of Photovoltaic Investors</strong>

All photovoltaic inverters have the same common task: converting solar DC power into useful AC power for our home. However, there are three different inverter technologies that we can choose for our solar panel system, and each of them works in a significantly different way.

String or chain inverters: a standard centralized inverter

Most small-scale solar energy systems use a chain inverter, also known as a “centralized” inverter. In a solar self – consumption installation with a chain inverter, each panel is connected in series. When they produce energy, they are sent to a single inverter, which is usually located on the side of the house, in the garage or in the basement. The investor converts all the green energy generated by your solar panels into electricity that you can use in your home or business

Pros : Chain inverters are the lowest cost option and are a more than proven technology. They are also easy to maintain, since they are easily accessible.

Cons : If our system uses a string inverter, it will only produce as much useful electricity as the solar panel that produces least. The generation of electricity in an installation with a string inverter can suffer the “bottleneck” effect, or be drastically reduced, if only one or two of the panels are shaded or not working properly.

Ideal for : Housing with “unobstructed” roofs that consistently receive radiation throughout the day, and for owners seeking photovoltaic systems at the lowest cost.

 

 Microinverters

If a string inverter can be considered as a “centralized” inverter, the microinverters are “distributed” inverters. In photovoltaic installations with microinverters each solar panel has a small solar inverter installed. Instead of sending power from all the panels to a single inverter, the micro-inverter systems convert solar DC power into AC power on the roof itself.

Pros : Microinverters are more efficient than string inverters. The installations of solar panels that enjoy this technology, continue to produce energy, even if one or two of the panels of the system have a lower performance. The microinverters also allow monitoring the performance of specific solar panels, which facilitates the identification of production problems if necessary.

Cons : Microinverters cost more than a chain inverter, and can be more difficult to maintain or repair in case of a problem, since they are on the cover.

Ideal for : Installation with solar panels with different orientations, owners who want to maximize the production of solar energy in a small space, and homes that have “complicated” covers with pediments, chimneys or other objects that can cause shadows.

Power optimizers: an option located on the panel to connect to a chain inverter

Power optimizers can be considered as a compromise between chain inverters and microinverters. Like the microinverters, the power optimizers are located on the roof next to – or integrated with – the individual solar panels. However, systems with power optimizers continue to send power to a centralized inverter.

Power optimizers do not convert DC electricity into alternating current at the solar panel site. Rather, they “condition” the electricity in direct current by setting the voltage of the electricity, at the moment it is sent to the photovoltaic inverter. An installation of solar panels with power optimizers is more efficient than one that only uses a chain inverter.

<strong style=”background-color: transparent;”>Pros : Like microinverters, power optimizers can improve the efficiency of the installation, and are less expensive than microinverters. They also offer the advantage of monitoring the performance of each solar panel individually, and reducing the effect of shadows on the performance of the installation.

Cons : A facility with power optimizers will cost more than a facility with a chain inverter.

Ideal for : Owners who are willing to pay more to increase the efficiency of their solar panel system, but do not want to acquire microinverters.

 

 

How to choose the best photovoltaic inverter option for your home or business?

Now that we understand how photovoltaic solar inverters work, the next step is to decide which type is better for our electrical self-consumption installation. In the end, the choice is reduced to how much we are willing to pay for additional performance, and if we are willing to pay for possible additional maintenance.

At SotySolar we can help you make that decision about your solar investor options. When you register your home, you will receive personalized offers from qualified installers, and you will be able to evaluate the costs and benefits of the different solar inverter options. We will accompany you during the process resolving any doubt that may arise. Start saving on your electricity bill, producing your own green energy.

What is happening in Europe with the Sun Tax and Self-consumption?

These are times of war for self-consumption and the sun tax in the European Parliament. In this post we are going to analyze the current situation in Brussels. Each of the parties has put the cards on the table and because the negotiation will be three-way, in SotySolar we dare not predict who will be the winner.

What do each of the parties say in terms of energy?

Image result for energy europe

The bodies that must decide before the end of 2018 the guidelines to follow in energy and self-consumption are 3: the European Parliament, the European Commission and the European Council

The European Parliament

The European Parliament with the socialist MEP José Blanco as spearhead approved the Renewables Directive where the most relevant aspect for photovoltaic self-consumption was the prohibition of the ” sun tax “. It was a reason for celebration. Perhaps precipitated because there is still a long way to go.

In this voting, only the Popular Party opposed, but still they have not given up in their eagerness to avoid the sustainable energy development by means of solar energy in our country.

The European Council

The European Council is a body made up of the 28 energy ministers of the member countries. The Spanish representative, is Álvaro Nadal, firm defender of the current regulations on self – consumption . As explained, later in the section “What does the Popular Party intend for Self-consumption and the Sun Tax?” The position of the Council is aligned with the Popular Party.

The Council’s position is really important. The States fund the initiatives proposed by the council, but not all is lost.

The European Commission

The third leg is the European Commission, and its position is not clear. The head of the European Commission is the Spanish politician Miguel Arias Cañete who is the Commissioner of Energy and Action against Climate Change. Your opinion is decisive worldwide. It occupies the 22nd position in the list of the 100 influencers of the energy sector according to the document ” The Future of Energy ” presented by the consultant Onalytica.

Everyone knows that Cañete belongs to the Popular Party but belongs to the branch of Agriculture and Environment, a great driver in the fight against climate change. Arias Cañete wants to leave the matter closed before summer to avoid that the decision-making falls into the hands of another.

What is the Popular Party trying to achieve with Self-consumption and Sun Tax?

Image result for sun taxOur government wants the homes, neighborhood communities and SMEs to have the same responsibilities as the energy lobby in our country. For this, they argue that since prosumers are going to participate actively in the electricity market and generate their own energy, consume it or sell it, there must be a certain equality with the big electricity companies so that everyone can play under the same rules of the game, that in his opinion “providing exemptions to some market participants means discriminating against others, which fundamentally undermines the structure of the market, increases costs for consumers and creates uncertainty for investors”. It seems a very reasonable argument but it is not like that.

Simply, at present, there is no equality between a large company and a small local consumer . For small producers of renewable energy in general, and solar self-consumption in particular, such as vineyards, schools or hospitals, administrative and financial burdens are a strong disincentive to participate in the production of green and clean energy .

To make it easier to understand, the Popular Party wants small consumers to pay a tax on the sun or toll of support for the energy they produce with their self-consumption installation , so that the electricity companies do not reduce their income. However, traditional power plants (nuclear, gas and coal) self-consume 8% of all the energy they produce, but do not pay any toll. Why will it be?

On the other hand, the Government affirms that the economic impact of the non-application of the tax would be astronomical but in reality it supposes 2 million € for every 100 MW installed, -in 2017, 135 MW of photovoltaic solar were installed-. Returning to the previous argument, if the Government charged this tax to the traditional power plants would mean an extra income of 230 million € for their coffers.

What will happen to the sun tax, self-consumption and the energy directive?

Image result for sun tax

Let’s recap The European Council is in favor of the ” sun tax ” and the European Parliament against, so the key figure can be Arias Cañete.

The work of this will be very complicated as it will have to deal with Moncloa but on the other hand it can go down in history as the person responsible for the biggest change in energy policy of our times. Loyalty without meaning or being remembered for posterity?

As a last point add that, recently, Arias Cañete has been positioned against Nadal and his own party to applaud the decision of the power plants to close the thermal power plants . According to what has been said, achieving the objectives of Paris requires the contribution of all the participating agents and the implementation of a European regulation that facilitates the transition towards clean energy and self-consumption.

In SotySolar we do not dare to predict the future, much less in these convulsive times in which we live. We will continue fighting for a sustainable world without taxes, but when the wind blows against the tide, we will continue, because for many taxes, taxes, tolls or whatever you want to call it, THE SELF-CONSUMPTION IS ALREADY PROFITABLE .

Is it worth investing in self-consumption?

Why is self-consumption not used to a greater extent?

Image result for self consumptionWhen we speak of electric self-consumption, we refer to the own production of the electric energy that we are going to consume, that is, in the same production site, later it is consumed. This sounds good, it even seems logical. If for that, in addition, renewable energies such as solar energy are used, it contributes to the improvement of the environment, due to the reduction of consumption of other polluting sources. But how much does a solar panel installation cost? Can it be used in Spain? And if so, why is it not done to a greater extent?

 

How much does self-consumption cost?   Can it be used in Spain?

 

After successive regulations of the Spanish electricity sector, solar photovoltaic self-consumption was also regulated. Surely we have all heard of the sun tax , however, this tax only affects 2% of the self-consumption facilities that are carried out in Spain, since it is applied to installations of solar panels of more than 10 kW, and most of those carried out in single-family homes or neighborhood communities are below that figure.

In addition to the tax, the procedures and all the administrative part necessary to carry out a self-consumption installation were regulated. This fact does not help people decide to install, since it involves a lot of time and effort, and an economic cost. In SotySolar we take care of this tedious part so that it does not suppose any inconvenience for those interested in a solar panel installation for solar self-consumption.

The surplus generated is also regulated. We refer to the part of energy produced by solar panels , but that is not consumed. This part can be: sold, stored in batteries or wasted. The last case is the one that has less room, it is not logical to waste energy when there are households that can not pay the electricity bills.

 In the case of selling it, the high bureaucracy in self-consumption does not make it profitable today. So the most feasible option seems to be the storage in batteries , which is already being used in some homes, allowing them to even disconnect from the network in some cases. However, solar batteries continue to be developed since, nowadays, they take up a lot of space, increase the cost of the initial investment and are not very ecological. In the not too distant future, they will be present in the vast majority of facilities.

Is it worth investing in self-consumption?

Image result for self consumptionHowever, ignoring the legal and administrative part, is it worth investing in a photovoltaic solar panel installation? To answer this question, several factors must be considered.

First, the price of your electricity bill

One of the main benefits of photovoltaic self – consumption is the savings that the electricity bill represents per year. The more you are paying, the more savings will be the installation of photovoltaic solar panels for self-consumption. The price of electricity has risen around 70% in the last 10 years, and will continue to rise. So, we must think of some way to avoid losing purchasing power by paying more for electricity.

Second, the cost of solar panels

It is evident that the investment that must be made in the installation of photovoltaic panels for self-consumption is a key factor to be decided. The cost can vary depending on the location, the type of installation, the installer of solar panels and the installed equipment. Therefore, it is necessary to compare the price and quality of multiple offers to choose the most appropriate one. You can use a platform like SotySolar to easily compare multiple offers.

Third, the location of your installation

Your installation of solar panels for self-consumption is powered by solar energy so it must be installed in places where there is sufficient solar radiation for the installation to be profitable. Fortunately, throughout the Spanish territory there is enough radiation and hours of sunshine to be profitable. In fact, Germany, with less sun than Spain, has 8 times the installed power in Spain. We are also behind Italy, France and the United Kingdom.

Fourth, the payment options with which the customer can count

Electric self-consumption is an initial investment that not all owners can face in a single payment. You can consider options such as financing it, or, somewhat less frequently, opt for your rent. That is, use leasing, as in the case of a car, so that it is paid for its right to use, while a company owns the self-consumption facility.

 

Taking into account the comments, and that most citizens are aware of the need for an energy change made a more efficient model and respectful of the environment, in addition to the economic savings involved, we just need a push to launch for it .

 

From SotySolar we want to collaborate in this “push” by facilitating all the procedures to make self-consumption facilities in homes .
