BEFORE CONSTRUCTION OF A PHOTOVOLTAIC INSTALLATION

The first step in the procedure for building a power plant for the sale of energy is to obtain an opinion on the conditions and manner of connection from the relevant for your region electricity distribution company. For this purpose, it is necessary to attach an up-to-date sketch and a document of ownership of the property.

In order to build an FPP entirely for the sale of energy at a preferential price, you must meet the following conditions:
FEC to be installed up to 30kWp installed power and to be installed on the roof;
The property should be in an urbanized area;
The property should have a legal building, which should be connected and have an open account to the energy distribution company.

Yes. The PV modules are made with special tempered glass which is hail resistant. They should meet certain international standards, namely IEC-61215 for polycrystalline and monocrystalline panels and IEC-61646 for thin-film panels. Upon certification the PV modules undergo a hail impact test where they are pelted with 25 mm (7.53g) hailstones at a speed of 23 m/s.
