Extra PV power

Did any of you with PV systems note generation of any extra power yesterday? With the cold weather, PV modules make extra power. This is one reason considering cold weather extremes during the design of a PV system is so important, as the voltage of the system can increase significantly during cold snaps, sometimes over the rated maximum voltage of charge controllers or inverters. This condition can be bad, either causing a system to shut down, or smoke. The good news is, if properly designed, you can make more power on cold days than during warmer weather. Call us if you’d like more information about making your own power from the sun.
