Startup fights the shadow losses involved with photovoltaics
Where there is light, there is shadow: Nobody knows that better than the operators of photovoltaic systems. A startup at Karlsruhe University wants to minimize such energy losses - for a reasonable price.

Even small shadows can reduce the yield of photovoltaic modules in a big way. As the young entrepreneurs explain, if shadows fall on only a twentieth of the surface, this can cause the panel to almost completely malfunction. The problem repeats itself because the modules are usually connected in series one behind the other. If the power falls in one module, then it falls in the entire plant, emphasizes Richard Brace, CTO of BRC-Solar. The startup's response was a patented circuit that is only attached to shaded modules. This increases the efficiency of the overall system while reducing capital expenditure.
