What determines the price of a photovoltaic installation?
As with everything, a number of factors influence the cost of a PV system.
First, the specialist must calculate the energy requirements of the property. To do this, calculate the annual electricity consumption, with particular emphasis on the months with higher consumption. This procedure allows you to determine the size of the photovoltaic installation and its power.
The second issue is the location of the installation. A different mounting system will be used for the installation of photovoltaics on the roof, and another - on the ground. It also differs with a sloping and flat roof, the type of covering (tile, shingle, sheet), etc.
Another factor is the technical parameters of the components - panels, inverter, cabling or security. Of course, the market offers materials made of various materials, with different durability and quality. It is up to the prosumer to have the last word, but it should be remembered that it is not always worth saving.
