Apartment complex with roof-mounted pv system for hot water generation

5/8/2019 / Russia, Sochi

70% gas cost reduction

Reference Russia - Sotchi - Fronius Ohmpilot

Apartment complex by the sea with roof-mounted PV system for hot water generation

 

The popular beach resort on the Black Sea is situated on the same latitude as Nice and is blessed with long, hot summers and mild weather in the winter and autumn months. The solar yield here is particularly promising, which was also why the owner of the apartment complex opted to produce their own electricity using photovoltaics.

 

Since August 2018, a PV system with Fronius Symo inverters has been meeting the household’s energy requirements. Not only is the electricity generated from renewable sources, but hot water is also produced using solar energy. “Since the start of 2019, roughly 90% of the energy produced has been consumed in the household itself. The Fronius Ohmpilot in particular is proving to be extremely cost-effective”, reports Denis Konyaev from Clever Energy LLC, a local Fronius Service Partner. “Up to now, the pool was heated and hot water was generated exclusively using gas. Since the commissioning of the PV system, we have been able to reduce costs in this respect by 70%.”
