A PV system for the hotel's own consumption is installed on the roof of the Schlosshotel Hellenstein. 

The PV roof system with an installed capacity of 219 kilowatt peak consists of a total of 516 modules from the manufacturer Trina Solar and produces around 199,900 kWh of environmentally friendly electricity per year. Around 94 per cent of this generated PV electricity is used for the Schlosshotel Hellenstein's own needs. The additional renewable energy generated is fed into the electricity grid. Compared to energy generation in a conventional power plant, this saves around 208 tonnes of CO2 per year.

With the installation of the new PV roof system, Schlosshotel Hellenstein is focussing on an environmentally friendly power supply from the power of the sun.
