“The Melbourne-based startup generates renewable energy and large scale energy storage by focusing sunlight with a field of aligned mirrors or heliostats onto a tower-mounted receiver containing an array of PV Ultra modules made of gallium arsenide PV cells. The heat extracted from the PV Ultra modules is then stored as hot water in a reservoir acting as a store. The ability to co-generate electricity and heat, the latter a captured by-product, makes the whole facility highly efficient.”
