NSG Group manufacture glass for photovoltaic panels and solar collectors but do not manufacture the finished items for direct use in buildings. A comprehensive range of TCO (transparent conductive oxide) glass is used in the manufacture of thin plate panels used in the direct conversion of solar radiation to electricity. The high transmission properties of Pilkington Optiwhite™ is also available to maximise the available energy in solar collectors.

Solar collectors use the heat from the sun to warm panels supplied with a circulating fluid. The heat gained is exchanged by passing it through a coil that passes it to a hot water storage system providing cheap hot water. With increasing fuel costs solar collectors are more effective than ever at reducing fuel bills and paying back the cost of installation.
