80% self-consumption with a 99.9 kWp roof-top system
Organic retailer saves 10,000 euros on energy costs a year
10,000 EUROS SAVED YEAR ON YEAR
The biggest electricity load at the retailer is the cooling system in the warehouse. However, it is possible to cover 40% of the energy requirements with solar energy thanks to the roof-mounted PV system. “The PV system is ideal for us. We require a particularly large amount of electricity for cooling when the sun shines, so it makes sense to use the energy for our own load consumers,” says managing director Gerhard Pichler. “The investment costs for the system will be recouped in 5 to 6 years.”
Payback period: less then 6 years
E-MOBILITY IN THE VICINITY PAYS OFF & IS FUN
Three of the company cars are electric vehicles from different manufacturers. They are charged using the Keba wallboxes installed on the premises. Naturally, the electricity comes from the company’s roof-mounted PV system.
“Switching to electric cars is worth it in many respects. For one, in Austria we don’t pay any benefit in kind. Secondly, we can charge the vehicles with our self-generated energy, increasing our rate of self-consumption. And thirdly, they’re a really fun way to get around,” adds Gerhard Pichler.

THINKING OF THE FUTURE:
At Biohandel GmbH, plans are being made to take even more measures to support the efficient use of electricity over the next few years.
- Optimising the cooling system
- Integrating an emergency power unit into the PV system
- Switching all the lighting to LED technology
