Precautions before installing the equipment
Before installing a solar panel, it is essential to take the dimensions of the project. To do this, you must take into account the number of people occupying the house concerned. Indeed, the daily consumption of hot water is estimated at 50-60 liters per person. A couple will therefore need a surface of 2 to 3 m² of solar panels. This surface can reach 3.5 to 6.5 m² if it is a family made up of 5 to 6 people. Improperly sized equipment can lead to premature aging of the entire equipment or overheating. The difficulty of the installation essentially lies in the connection to the circuit of the house and the calculation of the needs of each. For this, do not hesitate to call on a team experienced in the installation of solar panels.
The different components of the installation
- The photovoltaic panels are generally installed on the roof but it is possible to place them on a free ground directly exposed to the rays of the sun. The panels can be fixed or adjustable and their size varies according to the power sought. - The batteries used for the installation are slow discharge; their number varies according to the load capacity of the panels. - The regulator is the device which regulates the charge of the batteries. As soon as the batteries are recharged, the regulator automatically cuts the power. - The inverter functions as a transformer which is responsible for transforming the current between the installations at 220 volts and the energy delivered into direct current of 12 volts.
The various stages of installation
The installation of solar panels requires the application for a building permit or a declaration of work. Do not forget to consult professionals for the best advice regarding the various stages of installation. For the solar panels to be efficient, their inclination relative to the ground must be between 30 and 60 °. For a southern installation, an inclination of about 20 ° is necessary. It is important that you remove any obstacles that could shade the signs. In addition, the sensors should be placed so that you can easily reach them at any time. It is also essential to check the tightness of the cables and pipes crossing the roof, taking care to protect them from high temperatures. Do not forget to take care of the integration of the panels according to the architecture of your house, taking into account their shape, their insertion and their position.
