Without its structure, a photovoltaic solar panel is called photovoltaic module. Good knowledge and good maintenance will allow you to exploit them effectively.

What is the role of photovoltaic solar modules?

The role of the modules is to convert solar energy into electricity. A module is composed of photovoltaic cells that produce direct current when they perceive light.

The technology that allows this transformation into electricity is constantly evolving. Indeed, the service life, the profitability, the production of energy improve constantly.

In addition, the evolutions of the techniques of the habitat make of these modules elements of architecture and design which integrate in a more aesthetic way to the houses and buildings.

What is a photovoltaic module?

Silicon, a semiconductor material, which composes it is of a fragile nature. This is why the modules are covered with a layer of solid glass increasingly fine thanks to technological progress, able to withstand hail and climatic variations. The frame is made of aluminum.

Under the module, it is possible to find either a second glass plate or a hardened polymer designed to withstand the weather.

Photovoltaic modules are most commonly in the form of dark blue or black rectangular panels.

What maintenance for a module?

It is essential that photovoltaic modules are regularly maintained for optimal use. The dirt that can be deposited on a module is most of the time evacuated by rain but a regular check must be done.

By checking your meter, you can check if the production drops. This makes it possible to detect any obstructions and malfunctions.

It is possible to subscribe a maintenance contract which will guarantee the verification of the modules once a year by a professional.

What is the lifespan of photovoltaic modules?

The degradation is slow and their quality increases. Some modules have a life span of about 35 years and the majority of manufacturers guarantee them for a period of 20 to 25 years.

The first models in the early 90s lost a little less than 9% of their performance twenty years later.
