3.13.2011 – Sunday
At 1:42 p.m. the conditions were perfect and the Xantrex C60 charge controller read: 61 Amps / 819 Watts / 13.4 Volts
A note about the PV array: The Xantrex C60 charge controller is rated for 60 Amps continuous current and 85 Amps intermittent current. The panels are rated at 135W +5%/-5% output under ideal conditions. The voltage drop in our wiring from the panels to the charge controller is between 3-5%. When all this is taken into account the panels should theoretically provide about 780W to the charger. This more or less means that the system was momentarily functioning at 105% rated capacity (or 101% if there were no wire losses).
Solar Noon was at 1:02 p.m. today.
