Hello wrenches
We have a customer that wants us to promise kWh generation on a system, by
relying on just an irradiance sensor.
I think that a cell temperature sensor should be used as well to get a more
accurate picture of the actual weather conditions that the array will
experience. I'm
Hi Wrencher's
