A Flex Solar Panel is programmed according to the day and the seasons. These particular structures have an area that varies between 16 and 65 square meters and can reach powers ranging between 2 and 9 kWp. Concrete foundations are needed, and therefore a building permit. This solution is therefore complex, expensive and is therefore not recommended for individuals.
It is also possible to install fixed solar panels in your garden if the roof area is insufficient or it is mis-oriented. They are then placed on a fixed aluminum structure and oriented optimally. As for the solar tracker, concrete foundations and building permits are mandatory.
The polycrystalline panel is made from a multitude of small silicon crystals that are layered. It is often considered to be the most cost-effective in the case of small-scale installations (+/- 10 m²). Its price is lower because of its lower cost of production. However, it has a slightly lower yield than monocrystalline (11 to 13%) and its performance also decreases in low light or high heat.
A flex solar panel comes with distinct characteristics. Its cells are composed of thin layers of silicon deposited on another material (metal, glass or flexible plastic). Its lower price offsetting its lower yield, it is ideal for farms or companies that have large areas to deploy the panels. Its price is much lower because it uses only 1% of the silicon used for an equivalent surface of mono or polycrystalline panels.
When it comes to flexibility, it has a membrane or a solar sheet according to its support, which makes it adaptable to different installations. It is the most efficient in case of low sunlight, as in the northern regions. Its installation is simple. On the other hand, its energy efficiency is the lowest: only 5 to 7%. Its performance tends to decrease with time.
Solar energy
Solar energy is undoubtedly the source of all life on earth; it is responsible for all cycles of nature, responsible for the climate, the movement of the wind and the growth of plants. All renewable energies are based on solar energy. Energies, such as hydropower, wind, biomass and even waves and ocean currents are a consequence of solar power.
Depending on the location of the exhibition, 4m² of thermal solar panels can provide hot water for a family for one year and avoid the release of half a ton of CO2 into the atmosphere. Another form of installation uses photovoltaic solar panels to recover solar energy. A solar farm can have an area of several hectares producing electricity.
