In 2018, the roof is no longer used only to cover the house: it becomes a central support for the development of renewable energy. And this can be seen … more and more photovoltaic roofs appear on buildings: buildings now produce electricity thanks to the sun, an ecological and profitable system. Are you not yet equipped with a photovoltaic roof? To help build a green future, to take advantage of the financial benefits to be drawn from the car -with the sale of electricity or from the roof rental: find out how to transform the roof into a sunburnt center!
What is a photovoltaic roof?
It is a green energy production system, accessible to individuals and professionals. Concretly, it is a matter of equipping the roof with your home or its building with photovoltaic cells, integrated in IAB panels or overlapping or solar tiles. Thereafter:
- The silicon cells of tiles or solar panels capture the sun’s rays and transform this light into continuous electricity.
- This electric current is converted into alternating current thanks to a device called inverter – and located inside the house or the Pro building.
- Auto electricity -product is car -esumen by the manufacturer and/or sold to a supplier.
Tesla Photovoltaic Tiles, an advertisement for solar energy!
If photovoltaic energy has existed for a long time, good advertising was not useless to end up convincing the most skeptical! It is made thanks to Elon Musk who reveals the Tesla photovoltaic tile: solar tiles that integrate into the roof in a very aesthetic way.
The sunny earth explains you
Photovoltaic tiles or solar panel, what difference? Integration methods, price of sunscreen, performance … Discover the status of the Solar Market to choose your solution!
If this offer is intended for the public in general, it should not be forgotten that solar energy production systems are also available for the professional.
Zoom on industrial or agricultural buildings
Because the roofs of professionals’ buildings offer large exploitable surfaces – and even more performance! – The professional also benefits from the offers dedicated to the Solar Panel. The solar panels on the agricultural building, in particular, develop at an exponential speed in France.

For particular or professional, the implementation of solar cells on the roof of a building requires to satisfy some prerequisites, distinct according to the planned installation method.
Integrated photovoltaic system or overcoming solar panels?
There are 2 installation systems:
- The panels or tiles are integrated into the frame – IAB installation: they replace part of the traditional terracotta or slate tiles, without an extra thickness.
- The panels are overwhelmed by the roof (professional or home building): they are fixed above the coverage on the suitable frame.
Whatever the installation method chosen, it is essential to call certified professionals to avoid the risk of damage to domestic coverage – waterproofing problem, poor insulation – and make sure to respect the applicable administrative standards.
A free sunbish, how is it possible?
Give yourself a solar plant on the roof of your home, to become a green electricity self -producer, implies a significant financial investment.
Fifteen years ago, the prices of the solar panel were the main obstacle to investments. But today the profitability of photovoltaics is a reality: the price of solar panels has decreased by 80% in 10 years.
Solar earth reminder
To make the purchase price of the installation profitable, 2 solutions:
- The self -consumption with the storage or sale of the surplus, to reduce the quantity of its electricity bill and obtain its energy autonomy.
- Total sale to the EDF solar purchase obligation.
To make photovoltaics accessible to everyone, and therefore increase the volume of green electricity of renewable origin in circulation – for evident environmental purposes – there are financing solutions, including the free offer of photovoltaic roofs. It is actually a photovoltaic roof system for rental:
- The professional makes his roof available for an investor, who installs and manages solar panels.
- In exchange for the supply, the investor offers various remuneration options:
- Financing of part of the construction costs of the new building.
- Management of roof renewal costs – Asbestos removal, repair, change of coverage material …
- Payment of a rent.
- At the end of the emphasis leasing contract, the owner of the building may have it as he wishes!
Note: This system is particularly adapted to the agricultural photovoltaic roof, but the new roof rental system is developing for the benefit of the individual: rents his roof in exchange for which he receives a guaranteed annual lease income. Solar electricity without financial commitment, maintenance -free maintenance, it becomes possible!
