Why invest in photovoltaic solar panels ?

Photovoltaic solar panels: what is it?

Definition of a photovoltaic solar panel

The Photovoltaic solar panels are a device that allowsUse sun energy and ofMake electricity.

A photovoltaic solar panel includes Multiple components :

• · monocrystalline, polycrystalline or amorphous cells;
• · EVA envelope that protects these cells;
• · Aluminum chassis;
• · Back shell;
• · Glass plate.

The electrical part of the photovoltaic solar panel allows it to be connected to the rest of the solar installation.

Operation photovoltaic solar panel

Photovoltaic solar panels are installed on the side of the roof most exposed to the sun. It is composed of Photovoltaic cells Containing silicon: they are the ones that transform the sun’s energy into electrical voltage. The direct current that is generated is then changed to alternating current by the inverter.

When the electric current is produced, two possibilities are available to the energy producer. Electricity can be transported to the home electrical panel to be directly consumed, or injected into the public network and sold to EDF.

Thus, the autonomous production of renewable energy makes it possible to Reduce electricity bills or of Benefit from additional income In case of resale of the surplus.

How many solar panels need to be installed to be profitable?

It is difficult to precisely establish the number of solar panels that are necessary for all houses, because the power of a photovoltaic installation depends on several things: sunshine, type of project, yields of solar modules, etc.

It is necessary to base oneself on the Amount of your electricity bill and his Power consumption needs To choose the number and size of solar panels.

It is estimated that 8 solar panels are needed to produce a power of 3 kWp. To reach 6 kWp, 16 solar panels must be used; For 9 kWp, it is necessary to invest in 24 solar panels.

What is the lifetime of a photovoltaic installation?

The lifetime of the components of a photovoltaic installation

In general, it is estimated that the Solar panel lifetime is of 40 years. Solar panels produce 80% of their initial performance during the first 25 years of their use. After this time, the installation has a performance drop of 8.2% on average, but the solar panels are still in working order.

The longevity of theinverter varies depending on its type. Indeed, a central inverter has a lifespan of 10 years on average, while micro-inverters can be used for 20 years. It is therefore estimated that an inverter has a lifetime included between 8 and 12 years old. However, after this time, the inverter stops working.

Thus, a properly maintained photovoltaic installation can last nearly 40 years, with a change of inverter every decade. Investing in photovoltaic solar panels therefore allows you to benefit from an excellent return on investment.

Recycling: What happens to worn photovoltaic panels?

Photovoltaic solar panels can work for up to 40 years. After this time, this equipment can be Recycled up to 95%. In France, the Soren eco-organization takes care of the recycling of photovoltaic waste by organizing collections and ensuring their transport.

For Recycle photovoltaic solar panels, a sorting is carried out to separate the different constituents. Once done, the panels are cut into slats and pass through several grinding cycles. It is then easier to recover the different elements that compose them: glass, silicon, composite, copper, etc. Each of these elements is then transported to the recycling channel that corresponds to it.

Investing in photovoltaic solar panels thus makes it possible to double respect the environmental values. On the one hand, the production of green and decarbonized renewable energy makes it possible to participate in the energy transition and the fight against global warming. On the other hand, the equipment used to produce this solar electricity is recycled with the greatest respect for the environment so that this investment remains consistent with the challenges of sustainable development.

Installation of photovoltaic solar panels: at what cost?

The Price of a photovoltaic installation Varies according to several parameters:

• brand and power of the installation;
• Type of panel, inverter and meter;
• · Type of project and coverage;
• · height of the building;
• place of residence…

However, it is estimated that the Average price of a photovoltaic installation is understood Between 1470 and 2100 euros including tax per kilowatt-crest. This pricing is most advantageous insofar as the price of a photovoltaic installation has dropped by 65% since 2009. In addition, many State aid make it possible to partially or fully finance its solar panels: self-consumption premium, subsidized purchase price, reduction in VAT… Added to this is the high profitability photovoltaic solar panels, which offer a return on investment between 8 and 14 years old, with a 9% rate of return. The financing of a solar installation is thus quickly profitable.

In short, investing in photovoltaic solar panels makes it possible to respond to ecological and financial challenges. The green and decarbonized energy that is produced can be consumed or sold. Individuals can benefit from several financial aids to obtain their installation, whose profitability and longevity ensure great profits. It is therefore more than advantageous to go green with photovoltaic solar panels!
