HYBRISTAR and their partner companies develop and produce high efficiency solar hybrid collectors – also known as PVT collectors – air-to-water heat pumps and water/brine heat pumps, which are among the most reliable sources of electricity and heat. Hybrid technology multiplies efficiency from just under 20 % to over 80 % by combining photovoltaics and solar thermal in one collector . In this way, the effective solar yield on the available roof area can be more than tripled compared to conventional photovoltaic modules. This synergy effect offers a great advantage in terms of the degree of sustainable energy supply, especially for buildings in densely built-up areas. PVT collectors turn your building into a home power plant and not only save electricity costs, but also heating costs at the same time, thus significantly reducing CO2 emissions. When used as an additional heat source with our MAXIMUS EARTH water/brine heat pumps, our PVT collectors are subsidized by the government with up to 40% of the purchase cost! Stable operation with high performance up to an ambient temperature of -20° C. Our MAXIMUS AIR air-to-water heat pumps are equipped with continuously variable inverter technology and a brushless fan with variable speed control. This allows the heat pump to adapt to the energy requirements of the heat consumers. The refrigeration system, equipped with EVI (Enhanced Vapour Injection) technology, ensures high efficiency even with traditional radiator systems and also h
