Core Technologies

BSR Solar Technologies has a rich pipeline of proprietary technologies:

Stirling

BSRsolar's Stirling technology SUNPULSE^TM is a technology for crankless, non-resonance, free-piston engines. BSRsolar develops engines for two temperature ranges:

	Low-Temperature Stirling Engines powered by unconcentrated solar radiation with 80°C to 130°C at the hot end
	Medium-Temperature Stirling Engines powered by concentrated solar radiation, biomass, exhaust heat or gas, operating at 200°C to 500°C

Heat Storage

BSRsolar's Heat Storage Technology SOLARSTORAGE^TM is a thermo-chemical storage technology for medium-temperature (200°C to 500°C) heat. The thermo-chemical storage system is specially suited for round-the clock operation of solar-powered systems and to overcome longer periods without sunshine as they occur in the Northern Hemisphere. For sunbelt countries, BSR Solar Technologies has developed a system utilizing plant oil as the heat-storage medium.

Concentrator PV

BSRsolar's Concentrator PV Technology, COOLPHOTON^TM, enable hybrid thermal/photovoltaic systems with concentrator PV modules cooled frontside through a selective filter, extracting the infrared radiation for thermal energy generation and preventing the PV cells from becoming too hot and thus less efficient.

Hot-Water Collector

BSRsolar's Collector Technology, SOLARBOX^TM, is a pressure-less, isothermal system with built-in water storage. Equipped with a special fluorpolymer foil, UV-radiation penetrates and disinfects, freeing the water from bacteria and viruses.

Lightweight Precision Solar Optics

BSR Solar Technologies has developed an innovative "pneumatic solar concentrator" employing a thin reflective foil combined with a drum and an air-under-pressure system shaping the reflective foil into a highly effective concentrating optic, as well as Fresnel lenses and mirrors and other special optics.
