<p>A current direction change system for a generator for photovoltaic modules comprises a generator functioning as a consumer as for surface heating in buildings. In winter, following evaluation by a light, heat or rain sensor, the buildup of snow or ice layers and the shading of solar panels by these layers can be prevented. Current direction change can occur through switch changing of an inverter, by software change or by an external switch on the inverter and the generator field can be reversed in darkness.</p> |
