The handy monocrystalline solar module weighs only 18 kilograms and is therefore ideal for installation on the roof at home. The dimensions are 1,700 by 1,016 by 40 millimetres. N-type solar cells are based on negatively charged silicon. Their advantage: they are less susceptible to metallic impurities. LG offers a linear performance guarantee of at least 90.1 per cent after 25 years for the modules. At the same time, the temperature coefficient is reduced once again to 0.34 per cent per degree Celsius. (mfo)
