PrefaPrague

93 kWp rooftop PV plant is an effective and efficient use of the roof space of the factory

We built a 93 kWp solar power plant for Prefa Praha, a company specialized in the production of prefabricated concrete structures. The power plant covers approx. 20 % of the factory’s energy consumption, and the cost of the investment should be recovered in 12 to 13 years. In order to maximize the power output and the use of the roof space, we chose the east-west panel orientation.

Use of local resources

We used Prefa’s cranes and other heavy machinery the company had on site, which helped us save time and additional construction costs.

Project finished in 8 days

It took us no more than 8 days to complete the construction of a solar power plant installed on the rooftop of a cut and bent rebar factory. The factory remained in full operation during the construction.
