Re: Performance question?
My system (just south of San Francisco, Bay side of coastal hills--more sun and heat)--logged by eyeball when walking by, so I may have missed other peak values--3kW is peak inverter rating anyway so I would not expect much more):
- 5110 watts peak/5460 watts of panels = 93.5% (output / name plate)
So--your system, for a warm climate, sure sounds like it is running well for a warm climate.
- 3,000 watts peak /3,500 watts of panel = 86% ratio (output / name plate)
One note, some brands/models of solar equipment (particularly solar charge controllers) tend to over estimate power produced by upwards of 5-10%. (I don't know accuracy range of SMA). So take any production numbers with a grain of salt unless independently verified or Inverter specifics meter accuracy.
In the end, keep track of kWH output (by month or year)--and watch year over year production for any dramatic fall-off in power output (my guess, any year over year numbers with less than 10% differences is normal weather variations).
20x BP 4175B panels (replacement) + Xantrex GT 3.3 inverter for 3kW Grid Tied system + Honda eu2000i Inverter/Generator for emergency backup.
