How long does it take to pay off the installation of solar panels at home?

Faced with suffocating quotas from electricity companies, It is becoming more and more profitable to bet on photovoltaic panels to generate energy in our homes. It seems that everything comes together to select this clean resource: on the one hand, the unstoppable rise of the receipt; on the other hand, the lower cost of solar installations as well as the conveniences given by the administrations in the form of subsidies, subsidies and tax credits.

However, the key question many consumers ask is: How profitable is it to install solar panels in a home?

All consulted companies and experts agree that the savings associated with choosing this route are undeniable.

First of all, we should consider the cost of solar panels and other installations that we will make at home. The total cost of the investment can range from 9,000 to 16,000 Euros for a standard house (a family of three or four).

Assuming a cost of €16,000, depreciation can be realized in about eight years.. This will be possible thanks to a savings of 2,000 Euros per year on the electricity bill. This savings could be even greater if the evolution of rates continues to increase.

We will be saving exactly what we spent in those eight years, meaning we will have amortized the purchase.

It should be noted that this calculation, made by specialized portals such as, smartspain, idealista and others, does not include bonuses and subsidies made by municipalities more and more often, which means additional savings.

In any case and depending on the circumstances, The depreciation margin can vary from a minimum of five years to a maximum of 12 years.. But even in the worst-case scenario, it is still profitable. And this is so, because the service life of the photovoltaic installation in residential premises often reaches 30 years.

Solar industry experts say that as long as the payback period of the panels is less than half the life of the system, we will face a profitable investment.

Batteries for remote homes only

These calculations always apply to facilities that do not have a battery to store energy and can also generate electricity at night or during very cloudy periods.

However, according to another company in the industry, EFC Solar, most panels being installed in Spain do not contain batteries as they are not strictly necessary. Yes, for homes located in remote locations and disconnected from the public mains.

This company claims batteries “unnecessarily increase installation cost and reduce profitability”In most cases.

They can only be useful if energy consumption is to be made when there is no sun.

Ordinary installations without batteries allow us to continue using the conventional energy grid if necessary. And the excess solar energy captured by our panels can also be ‘tipped’ to the grid, which means an additional discount on the bill.

Installers point out that the panels continue to capture light and generate electricity even on cloudy days, as long as it’s not very permanent and it’s very cloudy.

In every situation, considerations There are several when hiring solar panels installed in our home:

-A detailed estimate of the installation find out how much everything will cost while it’s already running and compare that cost with the cost of the current electricity bill.

-To know whether the depreciation period will be more or less long, Find out what assistance is given by our city council or autonomous community for such installation. You should learn this and add these bonuses to the budget.

– consider the possibility loans or loans you will demand payment for installation as it will also change the budget (in this case upwards).

-If you live somewhere place isolated from the conventional electrical grid, you will have limitations of solar power supply during the night because you will only depend on your plates. In this case, you should inform yourself about the costs that a battery will lead to energy savings, which will make you completely self-sufficient.
