We built a 150kW photovoltaic plant for our own needs and sale of excess electricity, built on the roof of a warehouse of the Technostroy company in the city of Sofia.

Documentation for ERM West and Iskar region was maintained by VVT Engineering. The project in all necessary parts was prepared by VVT Engineering.

The construction was designed by VVT Engineering EOOD. The construction is made up of two parts – metal, which is made of metal trusses and aluminum profiles for mounting the photovoltaic modules. The metal structure was built by the investor, and the installation of the aluminum part by VVT Engineering. The plant consists of 277 Bauer Solar photovoltaic modules with a power of 540W with a 20-year product warranty and 3 Kostal Piko CI 50kW inverters with a power of 50kW and a 5-year warranty.

The entire construction of the plant took 21 working days. After the construction of the photovoltaic plant, all necessary declarations and quality certificates were issued for the purpose of commissioning.
