The installation of solar thermal or photovoltaic

There are two categories of solar panels, functioning quite different. Some capture the sun's heat. Other sontson transform energy into electricity. It should make the difference.

Produce hot water

To feed a CESI (individual solar water heaters) or SSI (SCS) , the sensor installed on the roof is designed to absorb heat and transmit it to a storage tank via a hydraulic system. So it's a big box of dark, lined with glass, through which a coil filled with water.

The sun heats the box and then water it contains. It then transmits its heat to the storage tank through a second coil. This solar energy is recovered to heat the water in the shower (CESI), or feeding a heated floor (SSI).

Produce electricity

In a photovoltaic panel, there is no water. It consists of silicon chips that produce bluish features when illuminated. This silicon is especially characteristic of this transform light into electricity.

A photovoltaic panel is an assembly of chips, connected together, producing an electric current. It is transmitted via a standard cable to electronic equipment which can transform to make it usable. Upon exiting the facility, you can use this power to sell or ERDF.

How to sell the electricity you produce .

Solar panel: the location

On a roof, facade, terrace or porch, installing solar panels is done on different surfaces. A solar panel should receive maximum sunlight. The ideal location is south with a slight slant .

This depends on many factors, mainly your place of residence, type of panel and use you make of it. Other factors should be taken into account and including the effects of mask, that is to say everything that can make the shadow on billboards throughout the year and whatever the position of sun in the sky.

Be alert to factors of shade around your house, trees, fire ... as well as possible glare caused by the glass surface of the solar panel.

Installing solar panels: installation

The installation of solar panels is difficult and requires a certain know-how . In the vast majority of cases it occurs on the roof. The panels are then added to the above dessusau coverage or embedded in it. In these circumstances, we must particularly be attentive to the possible consolidation of the structural and sealing problems. It is better to entrust the installation to a professional signer of the charter QUALISOL (hot water) or QualiPV (PV).

Installing solar panels: the obligations and aids

A statement of work must be done with the council. If you make a solar system when building a house, enter it on the building permit . The solar installation can enjoy certain benefits:

- Tax credits on equipment installed;
- 5.5% VAT if the installation of solar panels is done by a professional; 
- Using the Anah;
- Support of ADEME;
- Grant to your local authority
