Further information

Photovoltaic: you’re backing renewable energy.

Let the sun work for you. With a photovoltaic system, you are not only generating your own electricity, but you are also making an important contribution towards sustainability and climate protection. Take the first step towards a clean future and make use of our know-how – we’d be happy to advise you.

Renewable Energy

The sun is the largest and most durable energy source in our solar system and produces approximately 15,000 times the energy used by the entire human population. And the best part about it: even in several million years, that won’t change. So if you’re interested in improving your personal environmental footprint, reducing CO2 emissions and minimizing pollution while at the same time generating energy, this is the solution for you.

Thanks to the rapid development of ever more powerful panels, it is possible to integrate photovoltaic systems in all imaginable sectors.

Technical Execution

You can count on quality from LOHR. Our skilled technicians and specialized fitters follow the currently valid Austrian standards (ÖNORMEN, e.g. E 8001-4-712) and are always at the cutting edge of technology. In addition, our constantly growing portfolio is exclusively made up of high-quality components from leading producers in Europe. We can therefore guarantee constant quality that delivers what it promises.
With LOHR you are gaining an experienced partner who works professionally and reliably to make your wishes come true – from planning and financing to installation and maintenance, regardless of whether you have a private household, farm, small or medium-sized enterprise, or professional industrial facility.

Success Stories


Success Stories

Youth Residence KWJ

LOHR built the electrical installation in the Preindlgasse addition with a central battery. The implementation included emergency lighting, a fire alarm system, ongoing support and fault correction, as well as the room renovations BT1 + BT2 according to a fixed schedule and the new installation of a child care center in the Reichsapfelgasse house including ongoing maintenance.

Single family home

LOHR was given the challenge to use this complicated and partly shaded roof with three different irradiation angles in the best way possible for PV. This 5.5kWp system was realized using 17 high-quality 320W modules from LG, individual module analysis, and an inverter from SolarEdge.

ERGE, a specialist for planning and implementing gas, water, and heating installations, received a commercial 35kWp flat roof system from LOHR consisting of 122 265W modules from Astronergy and 2 17kW inverters from Fronius. The system’s optimum ballast was achieved with gravel.
