Energy: operation, assist, profitability… what you need to know if you want to install solar panels

important
As the power disaster does not appear to be going away, an increasing number of French persons are betting on photovoltaics to obtain some power financial savings. But among the many various kinds of solar panels and their advantages, navigating is tough. La Depeche takes inventory.

Photovoltaic sector is booming. According to a report by think-tank Ember, 18 of the 27 EU member states recorded solar manufacturing this summer time, notably the Netherlands (23% of its electrical energy combine), Germany (19%) and Spain (17%).

But as Emmanuel Macron referred to as on the French final Monday to be in “the assembly place of peace”, an increasing number of households, anxious to trim their power payments, are putting in solar panels on their roofs. Are you considering of leaping your self? We clarify the whole lot you need to know.

How do solar panels work?

Simply put, solar panels seize power from the solar’s rays and convert it into electrical energy. There are two forms of solar power: thermal power, which is used to provide a heating circuit and produce scorching water, and photovoltaic power, which is used to generate electrical energy and energy your own home’s lights or varied units.

Their precept is predicated on self-consumption: you take the electrical energy you produce and in a approach grow to be your individual power provider. But it is usually doable for you to inject some and even all the power produced into the general public electrical energy grid.

What is electrical energy saving?

According to NG information, photovoltaic electrical energy saves 200 to 600 euros per 12 months. Even if this determine actually relies on the calibration of your panels, you can anticipate to measure up to “20% of your power consumption”, explains Aurian de Maupeou, co-founder of Selectra, an organization specializing in evaluating electrical energy affords.

What are the advantages?

If it’s doable to resell its energy to EDF, the calculation immediately is “not likely worthwhile anymore”, warns Orion de Maupieu. “It shouldn’t be very handy: when you use your individual power, you pay 17.4 cents per kilowatt hour. If you promote it to EDF, it’s 10 cents per kilowatt hour. The calculation is completed rapidly”, continued the knowledgeable.

What assist?

With these components in thoughts, if you are contemplating taking the course your self, know that you are positively eligible for state support. In reality, due to the environmental advantages of photovoltaic self-use, you might be supplied varied advantages.

First, you can benefit from a photovoltaic self-consumption bonus. To do that, you simply need to install solar panels and generate your individual electrical energy. The bonus quantity is reducing and varies in accordance to your set up capability. This can vary from 80 euros per kilowatt peak (or kWp) for essentially the most highly effective installations to 380 €/kWp for the weakest.

Second, you can profit from a decreased VAT price. Indeed, “photovoltaic installations related to the community with an influence lower than or equal to 3 kWp can profit from a ten% VAT price”, can we learn on the general public service web site.

How a lot does it value to install them?

According to the Hellowatt web site, which makes a speciality of optimizing power payments, it invests between 9,000 and 23,000 euros for any set up between 3 and 9 kWp. However, this worth might range relying on varied components, equivalent to energy, know-how used or model. The geographic space you reside in can also be important, because it determines the quantity of daylight that the panels can profit from.

More exactly, for a medium-sized home (112 m2) positioned in metropolitan France, it’s vital to calculate “between 9000 and 12,000 euros”, explains Kevin, marketing consultant of CR2P, provider of solar power tools.

Finally, keep in mind that solar panels are normally worthwhile after 8 years. As for his or her lifespan, it varies round 30 years on common.
