Discover the science behind

and inside the PIDbox

The PIDbox regenerates solar cells by inducing a current back to the panels over night. This blocks potential induced degradation and makes the efficiency of solar panels increase up to 95% after 40 days. The panels will generate less heat, benefiting both yield and solar panel lifespan.
