  • This is the final balance of system video on the grid tied solar system I originally installed in October 2008. String One is 16 Mitsubishi Electric UD185MF5 poly-crystalline panels. String Two is 14 Kyocera Solar 158G panels. Combined nameplate wattage is 5172 watts @ STC. Inverter is an SMA SB4000US, rated at 4000 watts continuous AC output. As of October 2008 to date, this system has produced 6105 kwh, with a net metered utility reading of 10012 kwh. My own deration calcs put real world output at approx 3750 watts real-time, with daily summer averages of approx 20-25 KWH. This was a fully permitted self-installed system with a total price tag of $24k after rebates and incentives.
