Innovative frame design can significantly increase the efficiency of solar home systems by reducing the temperature of solar modules when in use. This has been demonstrated in tests conducted by the off-grid solar module manufacturer OPES Solutions. The company investigated the temperature performance of various PV module and mounting solutions on a typical corrugated sheet metal roof. The material is frequently used in Africa and heats up particularly strongly in sunlight. In tests, the “T-Frame” module developed by OPES Solutions, reduced module temperatures by over 6°C and is now being used by Azuri, one of the market leaders for high-quality Pay-As-You-Go solar technology.
