Hey Now All Wise ones!
An of gird client emailed yesterday that his Solark had been accepting only 350 watts of a 4KW input from the array. The modules are Q-cell 325 watt 2 strings of 7 modules. Sunrise, full sun, no clouds so no edge of cloud effect, negative temps @ - 6˚F, he waited all day with no improvement or change in the charge rate consistent 350watts input & then same thing next morning. Negative temps & full sun & 350watts solar input. He turned the Solark off for 10 minutes & then turned it back on & 4KW charge input returned. The Solark did not turn off or deliver any alarm or warning. My initial thought was over-voltage spike, we designed for a -25˚F scenario & 110 PSF snow load. Beefy! I did not ask if it was windy additionally. Could this contribute to a colder array temp? I have always been of the impression that wind chill did not affect metal or glass that it has to do with moisture being driven off. Thoughts & suggestions? Dana Orzel Great Solar Works, Inc.
