Photovoltaic Solar Panels

Understanding the process of a photovoltaic solar panel is essential when using this technology. The photovoltaic solar module is a system able to capture the energy sent by the sun towards the Earth and to convert it into a continuous electric current. There is also equipment that produces hot water from solar energy.

Operation of a photovoltaic solar panel

The process of a photovoltaic solar panel is based on several elements:

  • A module composed of photovoltaic cells transforming energy into continuous electrical voltage;
  • An assembly system also called roof integration system that anchors the photovoltaic panel to the frame;
  • An argument that establishes a tight junction between the board and the rest of the roof.

How Does A Photovoltaic Cell Work?

Photovoltaic cells are electronic components capable of producing electricity from solar energy, thanks to the photovoltaic effect. Discovered in 1839 by Antoine Becquerel, this phenomenon is based on the behavior of semiconductor materials when they receive solar radiation.

 Added to this are the electrical equipment and in particular, the inverter which transforms the direct current into alternating current and makes it possible to supply your home, or the public electricity distribution network. The purchase price of a photovoltaic solar panel remains high but decreases year by year. Also, financial assistance is available to help you pay the cost of departure.

Indeed, when the photons of sunlight come into contact with these particular elements, they transmit their energy to the electrons of the semiconductors, which then generate an electrical voltage. The most widely used semiconductor material currently used by PV module manufacturers is silicon.

How Is The Efficiency Of A Photovoltaic Panel Measured?

The amount of electricity that can be produced by a photovoltaic solar panel during its operation is measured by its peak power, a data provided by the panel manufacturers. It corresponds to the power that a photovoltaic installation can deliver, under conditions of sunshine (1000 W per m²) and temperatures (25 ° C) optimal. To get an estimate of what this technology can do for you, depending on your situation and the specific characteristics of your home, check out our energy savings simulator. It should be known that the power emitted by a module will always be lower than the indicated figure, since its performance will depend on many criteria: its location, the efficiency of its photovoltaic cells, its implementation, its orientation, its maintenance, etc. The choice of panel performance is, therefore, an essential criterion.

Resell Electricity Or Consume It On The Spot?

It is not mandatory to resell electricity produced by photovoltaic solar panels. You can store it on site in batteries, and consume it directly to meet the needs of your home. However, to support this clean and renewable energy, the French State has put in place favorable purchase rates for solar power, well above the price of the electricity you are paying at the moment. As an owner, your interest may be to sell this solar energy to your electricity supplier. The benefit for you is to realize substantial savings.


Install Photovoltaic Solar Panels To Produce Electricity

I use photovoltaic solar energy since 1995. My first installation (800 watts/peak power plant) was located in Normandy. It included batteries that allowed stoker production, but I will not dwell on this equipment which has especially interest for the isolated sites of the network.

The second plant that I had built in my current place of residence is located in the North. Connected to the network, it was installed in 2004.

Seeing my installation, journalists at the time took me for someone a little crazy, a dreamer, in 2010 these same journalists introduce me … as a PIONEER of photovoltaics, the terms have changed in 6 years!

How To Choose An Installation? My Tips For Selecting Your Installer And Your Hardware.

Beware of the siren song!

When developing photovoltaic power plant specifications, some unscrupulous installers predict annual productions worthy of installations in the Bahamas or the West Indies. Other companies call you through call centers to tell you that they represent significant energy providers, that they have examined your satellite roof and that this same shelter will provide you with optimal performance. They will, of course, do the necessary to quickly get an appointment at your home to get a new contract.

The quote, the material: the points to control

The estimate

On the quote, be careful about the annual production announced. Try to compare with other facilities in your area. For this, you can consult sites of producers like BDPV, national associations like HELPFUL or local (Solar in North …). Do not hesitate to inquire about the info-energy spaces to visit private facilities.

The quality of the material

With the steady growth of the photovoltaic sector, we now find everything on the market. So be careful about the variety of the equipment and brands offered (photovoltaic solar panels, inverter …).

What is the power of the installation?

The plant has a surface of 20 m2. It consists of 14 polycrystalline sensors of 175 Watts/peak, for a total power of 2450 W / C, It is oriented south / east (20 °), and its inclination is 30 °.

Which material did I choose?

The material is entirely German: Conergy for the panels and SMA for the inverter. It cost 17,657 euros in 2004, but I benefited from regional aid and 15% tax credit.In the end, I paid 5 187 euros.The small peculiarity, I consume the current product, and I only sell the surplus to ERDF (40%) at the price of 0.15 euros (2004 contract). The amortization time will be 16 years or less if the amount of electricity increases.If I had built my installation in 2010, with the tax credit of 50% on equipment TTC, VAT on labor and equipment at 5.5%, local aid and any aid from ANAH, I estimate that the time of return on investment would have been much faster (5 to 7 years).

What is the efficiency of the installation?

Since 2004, its annual output is 1000 kWh produced by installed kwc, which is well above the regional average. Indeed, according to the Ademe, the yield in the North of France is 900 to 950 kWh produced by installed kwc.
