Here's another reason to consider solar for your home...
"Studies have shown that the average yield on commercial solar panels has increased by just 3.5 percentage points since the 2000s and seemed to be reaching a plateau. But Insolight's three founders – Mathieu Ackermann, Laurent Coulot and Florian Gerlich – wanted to push yields further and decided to try something radically different: build residential solar panels that employ the same kinds of cells used in satellites, which are very efficient but also very expensive."
"To keep costs down for the retail market, they developed a protective glass on which optical lenses can be placed that concentrate sunlight by some 100x and direct it to the tiny surface of the high-performance cells. That means the cells need to take up less than 0.5 percent of the solar panel surface. The founders also designed a mechanism that can move the cells horizontally by a few millimeters each way in order to follow sunlight throughout the day."
"Insolight boast an impressive 29 percent yield – a record."

The solar panels developed by startup Insolight boast an impressive 29% yield – a record for the retail market. These systems, which have now been standardized for mass production, contain lenses that focus sunlight on tiny high-yield photovoltaic cells, employing what is a pioneering approach for the solar-power industry
