How to Install a Photovoltaic Panel

Derive the electrical energy from the sunlight is a lovely idea, mainly thanks to the fact of being free. Unfortunately, the photovoltaic system, currently, is rather expensive, although with a negative trend. Thanks to government incentives can come from the expenses in a time ranging between 6 and 10 years, depending on the characteristics and location of the plant.

Three ways to install

The incentives also vary as a function of the environmental impact (aesthetic) of the plant, and they increase as more equipment is “invisible.” Non-integrated, semi-integrated and integrated are the three possibilities that you have to install a photovoltaic panel, in descending order of visual impact and thus increasing incentives for the energy produced. Let us now briefly know how to install these three types of panels.

The panels of a type not integrated must be used when the inclination and orientation of the roof are not such as to maximize the performance of the panels. Even the panels placed on the land, which must be correctly oriented and therefore require structures rather important, are classified as “non-integrated.”

How to Install a Photovoltaic Panel

Typically the optimal orientation is towards the south at an angle of 30 degrees to a horizontal plane. To obtain this, the panels are fixed to a structure, usually of aluminum, with a part that will be fixed to the ground or to the bearing structure of the roof is substantial, to avoid possible problems due to the strong wind.

Installation on the roof

On the other part of the support, fixed with a suitable angle relative to the base seen previously, will set the photovoltaic panels. In case of installation on the roof, will be taken all the standards needed to prevent the infiltration of water, in the rain, in the room below.

The panels of semi-integrated can be used when the orientation and the angle formed by the pitch of the roof on which to install the implant is sufficiently correct. The panels here, too, will be established through brackets attached to the supporting structure of the roof under the shingles.

These brackets will link the profiles, usually of aluminum, which allows you to secure the panels. In this case, there will be the structure tilted to the brackets, but the structure and panels will be coplanar to the roof itself.

At the end of the photovoltaic panels will be positioned above the tiles, a short distance, with the same inclination. Even in this case, the fastening to the supporting structure and the subsequent covering of roof tiles can be made with the utmost care to prevent water infiltration.

Obtain Max. Contribution

To obtain the maximum contribution per kilowatt-hour produced and marketed in the network public light, perform a system with panels integrated into the roof structure This means you will no longer be “above” the tiles, but placed instead of the same, in so as not to protrude from the profile of the roof. In this case, the structure panels more mounting brackets must have a height less than that of the roof tiles.

Also, the panels themselves will need to be equipped with systems for a mechanical connection between a panel and the other that might be a watertight interface between the last panel. The tiles surrounding the area with the solar panels will be a waterproof membrane attached to both panels that the tile.

More recently, have been developed flexible amorphous silicon photovoltaic panels, which can be coupled to a waterproof sheet (polyethylene), and then glued on the roof, which in this case will be of the type without tiles, on a waterproof coating.
