Solar Collectors and Solar Thermal Systems

Sidebar Image

Dealing with the absorption of solar radiation and the transfer of heat energy to a working fluid. Solar collectors, although not sold directly to consumers, are an integral part of solar thermal systems. Solar water heaters, solar cookers, active solar house, solar greenhouse, solar dryers, solar industrial heating, and solar thermal power generation are inseparable from the solar collector; in all, solar collectors are either the driving force or core component of the system.

Solar Collecter Classification

By working fluid type: liquid collectors, air collectors By whether or not light is directed after entering the collector:concentrating solar collector, non-concentrating solar collector By whether collectors track the sun: tracking collector, non-tracking collector By whether or not there is a vacuum space: flat-plate collectors, vacuum tube collector By operating temperature: low-temperature collectors, medium collector temperature, high temperature collector

Eurofins Services

Eurofins can perform testing in accordance with EN 12975 and EN 12976 for solar collectors and thermal systems, and issue Solar Keymark certification. Solar Keymark is a voluntary certification program targeted towards solar water heaters that aims to help consumers select high quality solar products. A Keymark certified logo tells consumers that a product meets European standards, is popular in the European market allows consumers to receive government energy conservation subsidies.
