factors to consider
For this combination to have the effect we want, the first thing we have to take into account is the type of house in which we want to install the solar panels and the annual energy consumption. Knowing this, we’ll get closer to the number of plates needed to completely cover the power supply.
If we imagine that our house needs 7 solar panels and will have about 2,500 effective sunshine hours (this is the average number of sunshine hours we can get in most regions in Spain), we get the estimated total energy production Will get 3,675 kWh. With these figures on the table, the next thing we have to calculate is the energy consumption of our aerothermal heat pump.
If we take into account the installed average consumption per single-family house, it can be concluded that the aerothermal heat pump consumes about 3000 kWh per year. This consumption fully covers the cost of both heating and air conditioning in an average family home in Spain.
Thus, if we count the energy output provided by 7 solar panels (3,675 kWh) along with the cost of the inverter heat pump (3,000 kWh), we will be covering the annual heating costs. This means a cost close to zero, thanks to the combination of both renewable energy sources.
benefits of combination
Apart from the advantage of having an almost complete reduction in our electricity bill for heating use. The combination of both types of systems allows us to get more benefits when it comes to energy expenditure. For example, we can use the surplus energy in other household appliances or, even if we store a lot of energy, we can supply it to the electricity grid to get a discount on the electricity bill. Another advantage that this combined system offers us is its use for heating water. This way, if we are not using the energy generated for heating, we can allocate it to clean water in the house.
In conclusion, we can say that the investment in technology that manufacturers are making in their new devices brings us closer and closer to self-consumption. The only drawback we can take is that it depends on factors like having a good study of the area in which we want to install it, the type of our house and how much money we want to invest in a good energy system , which is not always pocket friendly.
