German company J.v.G. Thoma GmbH has launched its new LED Flasher Basic 2.0, which is used for photovoltaic solar module testing in order to calculate the output performance conformity of a solar photovoltaic module. This upgraded version features high levels of precision and long-term stability – important factors in the desert region solar panel segment where it is difficult to accurately estimate output. J.v.G Thoma has achieved this by creating an LED flasher where SEL and LEL are both possible. Each DESERT+® solar module receives 10 flashes to guarantee the best results. In fact, its accuracy is better than plus/minus 1 per cent.
