Vision & Philosophy

“All of us at SOLE share a common vision: reducing the environmental footprint of hot water production with renewable energy.”
SOLE S.A., Vision & Philosophy

We invest constantly in people, facilities and new technologies. Our know-how in solar water heaters goes back to 1974, and it lets us lead the developments in our industry rather than follow them.

Social responsibility

SOLE supports socially vulnerable groups, especially children. We give without seeking recognition, so we do not publicise our contributions.

History

Fifty years of firsts under the sun.

Research & Development

Solecon: concentrated sunlight up to 400 °C.

Together with the National Technical University of Athens (NTUA) we developed solar linear focus collectors. Reflector strips driven by a PLC solar tracker focus the radiation on a receiver, where the fluid reaches 150 to 400 °C.

CoolingCold water and air conditioning with absorption chillers.

Steam productionHigh-temperature heat for industrial processes.

DesalinationDrinking water from the sea without pollution.

Electricity generationFluid at 400 °C drives an engine coupled to a generator.

Support

Everything you need after installation.

Leaflets, user manuals and certificates, the same official documents published on sole.gr, in one place.
