Today, we talk to one of our solar energy companies in Bizkaia and Madrid. We will talk about its beginnings, its services, the future of the sector and its experience with us after a month on the platform.

1.- Tell us, how did AMM Capital arise?

AMM Capital arises in 2011 due to the interest of a group of professionals with long experience in the renewable energy sector to unite their capacities to develop projects that add value to society and its customers.

2.- Why did you decide to bet on solar self-consumption?

We bet for the self-consumption of municipalities, towns, urbanizations and industries in its beginnings not only in Spain, then to see the complexity of the regulations, the problems that were presented to make them and more recently the variants of being able to offer global energy self-consumption that includes electricity, air conditioning and electric vehicle charging we decided to include it in our activities taking into account the challenge of its long-term profitability.

3.- How has the path of AMM Capital been until reaching 2018?

AMM Capital’s path up to now has been in keeping with the times, with difficulties but always growing, with the satisfaction of having a group of clients who count on us again and again for new projects, to keep the built ones, to advise them in negotiations … we have gained their trust and respect in our profession and most importantly, with a united human team and highly integrated as a team.

4.- Do you offer other services besides photovoltaic energy?

We offer services in wind, mini-hydro, energy storage, energy management systems and network integration.

5.- After some difficult times, are you noticing a change in the perception of the population regarding photovoltaic self-consumption?

In this year we noticed a growing interest in the installation of self-consumption systems although the regulations do not facilitate it, we suppose that it helps that the professionals of the sector have internalized it and looked for solutions, as far as possible, to its restrictions. On the other hand, the price of solar panels has decreased in the last years making the installations less expensive.

6.- What period of amortization can a standard client expect when requesting a quote? And an industrial client?

The amortization always depends on the consumption habits, whether they are diurnal or nocturnal, with purely diurnal habits it is amortized in 4-7 years, if it is residential that always has a significant night component between 8 and 12 years. The key is to use that energy of light at the time of generation to generate ACS or air conditioning, be it cold or heat or load vehicles. Keep in mind that costs of electricity, natural gas and fossil fuels are reduced. If you want to use solar energy at night through storage, the amortization is between 15 and 18 years old, the positive is that it almost does not consume electricity from the network, obtaining greater savings.

7.- In your opinion, what should change or what measures should be implemented so that the sector can take off?

In order for the sector to take off, the limitation of installing up to 5kW on solar panels in single-phase installations must be eliminated, and the population must be educated on the possibility of using self-consumption as energy, not just electricity.

8.- When do you expect a true photovoltaic “boom” to take place in Spain?

We hope that there will be a boom when the regulations change if the general economic conditions of the country are maintained as in the last 2 years.

Now, let’s talk about your relationship with SotySolar :

9: – How did you know us?

We met SotySolar online.

10.- Why did you decide to try it?

We decided to try it in the presence of customers, unusual, near our headquarters for self-consumption. We had tried another website with very bad results in terms of the existence of true customers and we were reluctant. Talking with the SotySolar team gave us the confidence to do so.

11.- What type of publicity did you do before using our services?

We advertise on our website, industry media, Google+, Facebook.

12.- What advantages do you consider that SotySolar has contributed to your business?

SotySolar has provided a variety of clients.

13.- How would you rate the clients that come to you from our platform?

The clients are very hopeful with the self-consumption, we hope that the regulations allow some to obtain the solutions they seek and help them to decide

14.- In spite of having little time enjoying our services, is there any experience with an owner acquired in SotySolar that you wish to share?

At the moment we are in negotiations with everyone. Not yet.

What is green energy?

¿Qué es la energía verde?

It is a term that sounds very good and that is booming in recent times, but do we really know what it refers to? Is it possible to consume 100% renewable energy? How can we access it? We will try to answer these and other questions in this post.

What is Green Energy?

Well, we tend to tend to confuse renewable energies with green energy , and the difference is that all green energies are renewable, but not all renewable energies are green.

For example, the Great Hydraulics (> 10 MW) is a source of renewable and clean energy, but the important impact it causes in its river environment prevents it from being described as green.

When we talk about Green Energies we refer to infinite resources from non-polluting sources and respectful with the environment. This group includes energies such as solar, wind, tidal …

In 2016, in Spain, 38.9% of the generated energy came from renewable sources, wind heads the production with 18.4%, followed by hydraulics with 13.8% and behind were photovoltaic and thermal solar energy with 3.1% and 2% respectively, the remaining 1.6% corresponds to the rest of renewable energies.

How can I consume Green Energy?

Image result for green energyThere are several ways, but the only one in which we can be completely sure of the renewable source of our energy is self-consumption . By installing solar panels on our roof we can generate enough clean energy to cover 100% of our energy demand or a good part of it.

Another option to consider is to hire the services of any of the multiple marketers that currently offer their customers the possibility of consuming 100% renewable energy, and that is already more than 30 companies that advertise this service in our country. Now, as we already know, we must bear in mind that 100% renewable does not have to be 100% green and we will have to study the offers of the different marketers to make sure of the origin of our energy.


Can I consume only 100% Green Energy?

The answer is clear, Yes !, but only if you opt for self-consumption , because as we have seen before, it is the only way to be sure of the origin of our energy because we are the ones who are producing it.

Now, if you bet for the services of a green energy marketer we should know that, the electricity that reaches our house can never be 100% green, but do not be shocked, everything has an explanation.

It is impossible for the electricity distribution network to distinguish which electricity comes from a renewable source and which does not, the energy that comes to our homes is a mixture of both. So:

How can marketers offer green energy?

<strong>How can marketers offer green energy?</strong>

What these marketers really do is commit to buy as much energy as we consume, to renewable energy producers or even to produce it themselves.

With this system, our energy expenditure will go to companies producing renewable energy and in this way we will be encouraged to generate this type of energy, since the higher the demand, the greater the supply must be.

In order to demonstrate the renewable origin of the energy sold by the marketers, the Ministry of Industry created the Guarantee of Origin in 2007, which guarantees that all or part of the energy generated by a producer is renewable and can therefore sell it with this seal.


While it is true that the current model generates considerable controversy in the sector by not contemplating the obligation of investments in new renewable energy facilities, which may allow some production companies to obtain the seal, but not really bet on them.

In this aspect, transparency must play a key role in the development of this type of product, not so much of the marketers as of the producers. A more restrictive conditions when it comes to obtaining the guarantee certificate, surely, would help in this regard.

The future is renewable

In these lines it has become clear that clean energy has come to stay. Today it is in our hands to bet on it, either in the form of self – consumption , hiring it through a marketer or a combination of both solutions.


The future seems encouraging for renewable energies , in countries such as Spain, which meets all the conditions to be at the forefront of the energy revolution to which sooner or later we will be led and that is why we must take the reins and start take advantage of the renewable energies that we have at our disposal.

Aerotermia: What is it and how does it work? Advantages of combining it with solar panels

Aerotermia: ¿Qué es y cómo funciona? Ventajas de combinarla con placas solares

The aerotermia is booming. In recent years, many users have adopted this renewable energy as a system for generating heat and cold, replacing the traditional boilers that were common in homes.

What is aerothermia and how does it work?

The aerotermia systems are heat pumps of last generation that are used to produce hot water, cooling in summer and heating in winter. It is a highly efficient system.

The aerotermia is, therefore, a heat pump that extracts heat from the air to produce cold or hot water and use it for heating , air conditioning or domestic hot water (DHW) .

 Aerothermy can be associated with numerous heating / cooling systems such as underfloor heating, fan-coils (water-air equipment) and low-temperature radiators. The most common association is that of aerotermia and radiant floor.


Image result for aerotermia


The radiant floor is a system of heat / cold that has a high thermal inertia since the entire mass of the ground is heated so that it, in turn, warms the air of the house. Thermal inertia is the amount of heat that can accumulate and preserve a solid body. It is the cause that when we turn off the heating, the house stays hot for a certain period of time.

The fuel used is electricity and the yields range from 250% to 450% depending on the outside temperature and the water temperature that you want to reach, whether for use in radiant floor or hot water. In the areas near the coast is where you get the maximum performance of aerotermia equipment.

Aerotermia: What power do I need?

In order to know the exact power of an aerothermal equipment, it would be convenient to perform a calculation of thermal loads taking into account the effect of thermal inertia. The method recommended by IDAE is the RST (Temporary Radiant Series) and is summarized in the following image:

  For this calculation to be accurate, it must be done by an expert and there must be a safety margin on the 100% theoretical result for unforeseen events.

Let us suppose the following example: the calculation of thermal loads strut has determined that your single-family house needs 18 kW thermal at the time of maximum demand, so we would need an aerothermal equipment of at least 18 kW.

Let us suppose now that these 18 kW are only needed during the coldest 6 hours of the day, during the 12 intermediate ones we need 12 kW and in the 6 hottest ones we only need 6 kW.

In this case, we could provide a constant power of 12 kW (18 * 6 + 12 * 12 + 6 * 6) / 24 and use the thermal inertia in our benefit.

This is an example, although it is usual for cold and heat installers to use approximations of 50 W / m2 and 100 W / m2 depending on the location, whether the insulation is good or bad, …

Price of Aerothermia

In existing buildings, the average price of an aerothermic equipment is between € 1,200 and € 2,500 for homes with less than 4 bedrooms. The amortization can be between 5 and 12 years depending on the fuel to be replaced: butane is more expensive than natural gas.

Combination of Aerotermia with Solar Plates

Image result for aerotermia solar

The aerotermia machine can be supplied with photovoltaic solar energy in the event that the installation of solar panels produces enough electricity. In this way, we minimize consumption and optimize more savings.

If you combine photovoltaic energy with aerothermy to produce ACS, you can have a 350% more performance , that is, 3.5 kWh produced by each 1 kWh electric energy used in design conditions (outdoor temperature lower than 35ºC in summer and higher than 5º C in winter).

This combined solution of aerothermy with photovoltaic is more efficient than solar thermal energy to produce ACS.

5 reasons to combine Aerotermia with Photovoltaics

  1. The aerotermia can be considered a renewable energy because it contributes up to 75% of its energy for free thanks to the air.
  2. The performance of photovoltaic energy to produce ACS increases more than 80% together, exceeding the thermal solar performance.
  3. You use solar panels to generate part of the electricity needed by the aerothermal machine to generate heat and cold.
  4. The surplus of photovoltaic can use it for other electrical consumption of the house. The saving is double.
  5. The maintenance of both the installation of solar panels for self-consumption and that of aerothermy is minimal and much lower than any conventional boiler.

For these 5 reasons, the aerotermia with photovoltaic plates is an excellent solution. You are also saving energy and money without harming the environment.

The Town Councils and self-consumption

In this post we will try to analyze the crucial role that local administrations must play in the development of self – consumption within their territorial limits.

The current legal framework, with the RD 900/2015 that regulates energy self-consumption, allows municipalities to promote a new energy model more efficient and sustainable, through the adoption of different measures that we review below.

Tax incentives

Image result for tax incentives

With regard to the IBI (Property Tax and Real Estate), article 74.5 Royal Legislative Decree 2/2004, of March 5, approving the revised text of the Local Treasury Regulatory Law, provides for bonuses of up to 50% of the quota for real estate that has installed photovoltaic solar panels .

This RD provides a similar bonus for the ICIO (Tax on Constructions, Installations and Works), with up to 95% of the tax quota for photovoltaic self-consumption facilities .

Facilitate administrative procedures


It is in the hand of the Local Governments to establish in their ordinances mechanisms that simplify the implementation of this type of systems.

In the case of installations of reduced power, the substitution of a municipal license should be considered for a responsible declaration or prior communication, which would be a step forward in supporting a new sustainable energy model that respects the environment.

Obligatory self-consumption systems in certain buildings

It is possible that the local administration, through the approval of the due ordinance, imposes the obligation to use solar photovoltaic systems in certain cases.

With the aim of fulfilling the political will regarding sustainability and the environment, municipalities can impose the execution of self-consumption facilities in commercial buildings and services frequented by the public.

Lead by example

<strong>Lead by example</strong>

Municipalities, like the rest of Public Administrations, must take charge of the European Directives on renewable energies and promote energy self-consumption as the most responsible form of consumption that exists today.

It depends on the town councils to put themselves at the forefront of the energy transition that is already unstoppable, implementing systems of energy use in their own buildings.

It is the responsibility of Local Governments to mark their own energy policy and to strive to be the spearhead of this change of system, preaching by example.

"In general, they are very good quality clients, with very clear and well informed ideas about photovoltaics and its benefits." – Green Energy Quantum

Meet our solar energy companies – Quantum Energía Verde

Today, we talk to one of our solar energy companies in Seville. We will talk about his beginnings, his services, the future of the sector and his experience with us after a year on the platform.

1.- Tell us, how did Quantum Energía Verde arise?

Quantum Energía Verde was created at the end of 2016 by the union of a team of Andalusian industrial engineers who are experts in the field of renewables, who have developed their professional careers in multinationals such as Abengoa, Isolux Corsán or Solar Century, managing large-scale projects international.

This acquired knowledge is what we now want to transfer to the industrial and residential sector in Andalusia, offering energy solutions adjusted to the needs of each family and company.

2.- Why did you decide to bet on solar self-consumption?

Andalusia has one of the best performance ratios in Europe for the use of solar energy, together with the cheaper cost of materials in recent years makes this type of facilities very profitable investments for homes and businesses. There is also ‘everything to do’ in this field, so it is also a good contribution to reduce the dependence on foreign energy, and do it in a clean and sustainable way.

3.- What has been the path of Quantum Energía Verde until 2018?

From the beginning we make a great effort to publicize the possibilities of photovoltaic self – consumption , disseminating its benefits and advantages in a didactic way, addressing and trying to solve the myths and legends that revolve around photovoltaics and the aspects that have limited its growth in recent years. We try to offer quality information to anyone interested in these systems and, of course, we are an installation company and with much effort and dedication we are developing many facilities at the residential and industrial level.

4.- Do you offer other services besides photovoltaic energy?

At Quantum Energía Verde we are ‘by and for’ photovoltaics and self-consumption. We specialize in installations for residential, company and solar pumping, both in grid-connected or isolated installations, and we exclusively dedicate ourselves to this.

5.- After some difficult times, are you noticing a change in the perception of the population regarding photovoltaic self-consumption?

Fruit of the deep ecological and environmental awareness of the Andalusians little by little we are observing how there is a positive approach to photovoltaic self-consumption as a clean, green, sustainable and viable energy alternative. This is compounded by the boredom of citizens with electricity companies and the continuous increase in the electricity bill that makes them look for ways to be more efficient with energy consumption at home. In addition, from Quantum we made many efforts to demolish myths and legends about this technology as the issue of the nonexistent ‘sun tax’ or the general perception that these facilities have a very high cost. All this makes Andalusians increasingly interested in finding ways to reduce electricity bills at home and do it in a clean and sustainable way with renewable energies such as photovoltaics.

6.- What period of amortization can a standard client expect when requesting a quote? And an industrial client?

Currently, both companies and individuals in Andalusia can count on a subsidy that covers up to 45% of the cost of photovoltaic solar panel installations , so that, depending on each case, both private and business investments can be amortized between 4-7 years, if the accumulation systems with lithium-ion batteries are added to the facilities, the amortization period is extended between 5-8 years.

7.- In your opinion, what should change or what measures should be implemented so that the sector can take off?

There are many measures that would help boost the sector without resorting to incentives or subsidies: simplify administratively the legalization of facilities, regulate the collective or shared use of energy, eliminate the obligation to install a 2nd meter, implement some formula of ‘ net balance ‘, to make the legal limits for the installations more flexible, to subsidize the photovoltaic at municipal or local level or simply to give greater political and media diffusion to the advantages and benefits of the photovoltaic as clean and green energy for all.

8.- When do you expect a true photovoltaic “boom” to take place in Spain?

The high energy cost of families, together with the growing environmental awareness and the cheaper cost of installing photovoltaic solar panels, suggests that in the next decade many families and companies can join the photovoltaic current.


Now, let’s talk about your relationship with SotySolar:

9: – How did you know us?

Well, like almost everything today on the internet. So in the summer of 2017 we learned about the start-up of Soty Solar through news in digital media.

10.- Why did you decide to try it?

We thought it was very interesting that there was a portal like Soty Solar specialized in solar energy, with good web quality, good content and aimed at bringing exclusively to citizens especially interested in photovoltaic energy with companies specialized in the sector.

11.- What type of publicity did you do before using our services?

Traditional offline advertising and some online activity in other more general portals.

12.- What advantages do you consider that SotySolar has contributed to your business?

In addition to providing contact with citizens very interested in photovoltaics, they provide us with knowledge about the state of the sector, technical and political developments, always with a very careful and close treatment.

13.- How would you rate the clients that come to you from our platform?

In general, they are very good quality customers, with very clear and well informed ideas about photovoltaics and its benefits.

14.- Is there any experience with an owner acquired in SotySolar that you wish to share?

All customers feel very satisfied with their facilities. We speak mainly of individuals who already knew the photovoltaic and waited for a specialist company to carry out the project, something that with the relationship through Soty Solar they got.

By sharing the experience of some of them, we have a family in the province of Málaga who, shortly after starting up their installation with batteries, wanted to expand the accumulation system, because despite being covering more than 80% of their energy consumption in The house still produced more energy than it used, and of course, they did not want to waste even one kWh of energy from their photovoltaic installation.
