How does aerothermal energy combine with solar panels?

By combining a aerothermal installation with self-consumption photovoltaic installation we will receive multiply the benefits which in itself already provides the separate use of both energy sources.

Lost aerothermal equipment can extract energy from the outside air using a reversible heat pump. The system, which is installed outside the property, obtains heat from the air and circulates it through an internal circuit with coolant which is then transmitted to the air conditioning system inside the home, such as radiators, underfloor heating, boiler. , etc.

If a house is well insulated from the outside, orn system that integrates aerothermal energy with solar panels es the most efficient system which we can install to air condition a home.

Let\’s see below first what are the advantages of aerothermal energy and then how they are multiplied by joining them with a solar panel system.

The advantages of aerothermal installations

The installation of aerothermia The most common is usually achieved in conventional air conditioning or air conditioning installations by means of an outdoor unit joined to one or more indoor units. That is why it is very important that the house has a place outside where the aerothermic unit can be located.

Let\’s see what they are below the most significant advantages of aerothermal installations:

  • Simple, fast and economical installation.
  • 70% of the thermal energy for the production of heating or hot water is extracted from the outside air, and the remaining 30% of the energy is generated from electricity. In this way, savings of up to 60% on the electricity bill are guaranteed.
  • It can be used both in summer and in winter, because it is also valid for providing air conditioning.
  • It offers a high level of efficiency and performance.
  • It does not use fossil burning, so it is an energy that helps to take care of the environment. However, there is only one reason that prevents us from being able to say that the energy generated by aerothermal energy is 100% renewable, and that is that the heat pump in your equipment needs electricity to work, which means that you have to plug in the unit. to power the system.
  • Medium and long term savings.
  • It allows you to have cold and heat in the house with a single equipment.
  • It hardly requires maintenance.

The benefits of combining photovoltaic energy with aerothermal energy

As we just discussed, aerothermal systems need electricity to operate. For this reason, if solar panels are used to generate the necessary energy for the pump, an optimal end result is obtained, since the combination of photovoltaic energy and aerothermal energy to make ourselves able to achieve and completely sustainable and 100% renewable energy self-consumption.

The combination of both energy systems offers a range of benefits:

  • On the one hand, the energy produced by our solar panels is 100% renewablemaking our aerothermal equipment one as well, as it no longer needs to be powered by electricity from the conventional grid, it will be powered by fully renewable electricity.
  • At the same time, self-producing the energy of the aerothermal equipment through solar panels, new we will save electricity costs that we would have when using conventional electricity to power the system.
  • For every kWh of electricity consumed by the installation of solar panels, aerothermal energy is capable of producing 4 kWh of heat.
  • The aerothermal system has programmable consumptionTherefore, the combined plant will benefit because it is possible to coordinate the times of operation with the times when the self-consumption photovoltaic system produces the most electricity.
  • If the photovoltaic installation generates surplus energy Those kilowatts can be used with the aerothermal system because it has accumulators that will allow the energy to be used later.
  • Following the approval of Royal Decree 244/2019, if a photovoltaic system produces more electricity than it consumes, you can receive a economic compensation of energy surpluses or sell the excess energy in sales mode.

How solar panel and aerothermal system work together

In addition to using solar panels to power the heat pump, having a aerothermia system can make you Let\’s get even more from photovoltaic energy produced by solar panels. Currently, there are various aerothermal systems that have been specially designed to achieve the highest performance when combined with solar energy.

These pumps incorporate a regulation system that is integrated with the photovoltaic installation to take advantage of such times when the panels generate more electricity than is consumed and with the surplus hot water and store it for later use.

Therefore, these new equipments receive extend the performance of photovoltaic installation, which intervenes not only in the production of electricity, but also in the production of hot sanitary water for place to live.

Some hybrid systems even offer a backup device. Weather Forecast which allows them to predict the amount of energy the panels will produce and, based on that, make the best decisions.
