90 kWh GREENROCK saltwater batteries for nursing home in Belgium

After extensive energetic restoration the Flemish Minister of Energy, Lydia Peeters, officially opened the nursing home Sint Lambertus Buuren in Halen. A 90 kWh GREENROCK Business saltwater battery stores photovoltaic power for using during the night.  The storage system optimizes self-consumption and offers residents and caregivers a safe living and working environment, as the saltwater batteries are non-toxic, non-flammable and non-explosive.

The energetic renovation of the nursing home included insulation of 3,600 m² roof area and 212 kWp of photovoltaic. Further there is an intelligent heating system and the 90 kWh GREENROCK Business saltwater battery storage for optimizing self-consumption at the nursing home. After the renovation, energy consumption was reduced by more than 35%. More than that, CO2 emissions were even reduced by 40%.
