HopSol provides turn-key solutions for photovoltaic power plants. HopSol´s head office is located in Switzerland and the headquarter of HopSol Africa (Pty) Ltd has been established in Windhoek, Namibia, for its customers in southern Africa, where they have specialized in fulfilling the requirements of the solar industry for desert regions. Furthermore, HopSol acts as a wholesaler of all relevant parts for photovoltaic solar power solutions. Superior quality of modules and balance of equipment, along with engineering experience for desert conditions are crucial success factors.

This residential house has been equipped with a 7.2 kWp rooftop solar power installation and is expected to produce 16,000 kWh per year thanks to both, the high irradiation levels in Namibia and the very low temperature coefficient of Solar Frontier’s CIS modules. The low temperature coefficient of CIS thin-film modules leads to a smaller loss in conversion efficiency at high temperatures compared to crystalline modules, thus leading to better yields. The installation, with its 48 modules, also reduces CO2 emission by approximately 9 tons per year. Because of massive annual increases in electricity prices in Africa and high temperatures, Solar Frontier’s CIS modules provide an attractive and cost-efficient solar energy solution. In addition, the homogeneously black appearance of the Solar Frontier modules adds an outstanding aesthetic look to the residential rooftop.
