Our in-house production of top quality solar cells and our use of high-transmission, textured glass enables us to produce modules that maximize the energy yield of the PV system per unit area, and reduces balance-of-system (BOS) and installation cost per kWp. To minimize mismatch, we flash test every module we produce to within a power tolerance of +/-3%. We use the best materials available, such as specially designed robust, corrosion-resistant aluminium frames.
