Solar PV output in eclipse behind cloud
During a solar eclipse the sun was completely hidden behind cloud, but the low amount of light getting through reduced the output from solar PV panels to zero then back up over about two hours. The panels can produce 2.4 kw. so the 48 watts before the eclipse and 87 watts after shows the low light level.
Solar Eclipse - 20 March 2015
