Solar collectors capture the radiation from sunlight to provide free hot water. AES have been pioneering the design of solar thermal collectors since 1979 and this expertise allows us to manufacture collectors that are efficient, cost-effective and reliable. Every aspect of AES solar collectors have been refined through years of testing and constant improvement which means our solar thermal systems will save more CO2 emmissions and last well over 25 years.
AES has a wide range of standard solar collector sizes. Because all solar collectors are manufactured on site in Scotland, AES can custom design collectors to fit specific size requirements.
