The keys to saving energy thanks to the sun
Today, more than ever, we are looking for ways to lower our energy bills while also reducing our impact on the planet. One of the best solutions that we have in Spain is the use of solar energy. In fact, one of Spain's strengths is its large number of sunny days throughout the year: a strength that becomes a real advantage in terms of energy generation and savings. But, what data should we take into account and what solutions do we have within our reach?
“Year after year, we set consecutive records in the renewable energy sector. In fact, renewable energy has made fantastic progress. They outperform all other fuels in terms of growth and competitiveness. (...) but progress in the electricity sector is only a small part of the equation. Not to change the entire energy system is to be blind to reality” , warns Rana Adib, Executive Director of REN21.
In fact, to think of energy only in terms of electricity is to miss an important part of what constitutes the total demand for energy. According to the Report on the Global Status of Renewable Energies 2020, prepared jointly by the International Renewable Energy Agency (IRENA) , the International Energy Agency (IEA) and the Renewable Energy Policy Network for the 21st Century (REN21) , heat represents more than 50% of the total energy we consume in the world, three times more than electricity.
According to the same report: The boost in photovoltaics hides a significant lag in the heating, cooling and transport sectors. It would be short-sighted to celebrate the progress of the photovoltaic sector without acknowledging the alarmingly low and slow uptake of renewables in the heating, cooling and transport sectors. Electricity use, for example for lighting, household appliances and industrial equipment, only accounts for 17% of global final energy demand, while heating, cooling and transport account for up to 83% of energy what we consume The share of renewables in heating and cooling is low (10.1%) and barely increasing, although this sector represents more than half of the total energy demand.
It is impossible to ignore one of the two to answer the question. Therefore, it is essential to take it into account when thinking about energy savings before choosing any solution.
There are different solutions for the production of solar energy. Let's take a look at them again. First of all, we have the famous photovoltaic solar panel. This is well known, especially among individuals. Photovoltaic energy uses solar radiation to transform it into electricity. The electricity produced can be used for the common needs of a house: household appliances, television, etc.
Second, we have the solar thermal panel. It uses solar energy to produce heat to heat the water. This heated water can be used for hot water, heating, swimming pool heating or industrial processes.
Third, we have the hybrid solar panel. Far from being a new technology, on the contrary, it is still very little known. Hybrid solar technology is a two-in-one solution , since it allows the simultaneous production of electricity and hot water from solar energy. It is a kind of combination of photovoltaic and thermal.
But what is the best solution to save energy? If we take into account the above data, we should have both an electrical and a thermal response. Let's not forget that electricity only constitutes 17% of our energy consumption, so by opting for the photovoltaic solution, you will only be responding to one twentieth of the problem. The best solution is to opt for hybrid technology , which offers you a double and complete answer, since it will allow you to satisfy your energy needs in electricity and heat. Logically, as long as the building has a demand for heat, otherwise the best solution would be photovoltaic.
Now that we know the data that must be taken into account in our choice and that we know the range of solutions available to us and that we have chosen the best solution, that is, the hybrid. How can we optimize our installation and make the best possible decision?
Solar irradiation is the first factor to take into account when choosing solar energy, but it is not the only one. There are many variables to take into account such as height, shadows, existing obstacles that may prevent the reception of solar radiation. This is where things get complicated for many of us. But don't worry, Abora Solar will guide you through the process and provide you with various tools to optimize your hybrid solar installation.
To calculate the optimal configuration of your installation and find out all its benefits, at Abora Solar we have developed software that allows us to propose to our client the most appropriate and optimal installation , determine its cost as well as know the energy, financial and carbon emissions savings. CO2. It is an analysis tool that takes into account the irradiation, the inclination of the roof, the obstacles to solar radiation, the available surface of the roof and the energy needs of the client. Once all this data has been collected, we can propose an optimal installation plan at the lowest cost and, above all, one that adjusts to the specific needs of the building and the client.
aHTech: Save up to 70% on your bill
Betting on hybrids is a winning bet. In fact, if we review all the necessary requirements to save, we must:
- Resorting to solar energy: Spain's main asset, with the greatest solar energy potential in Europe and the highest solar radiation on the Old Continent.
- Find a solution that fully meets energy needs. That is, an electrical and thermal response at the same time.
- Have the means to optimize your facility in terms of space, production and profitability.
All these requirements are perfectly met by Abora Solar's hybrid solar panels with aHTech® technology . Abora hybrid solar panels produce the same energy as 4 photovoltaic solar panels. They produce electricity and hot water simultaneously with an efficiency of 89%, which is a world record. Thanks to them, you will be able to reduce your energy bill by up to 70% and your installation will pay for itself on average in just 5 years.
To achieve this, we also have the help of our monitoring system in which you can see how much energy your installation generates in real time. With your mobile or your computer you can see that the installation is working perfectly, and also if there is a problem, it can be detected without having to be in the installation. In this way, the time that the installation is stopped is minimized, being able to repair any unforeseen event as soon as possible.
