Family Size: 2 adults, 1 child. System purchased covers 110% of pre-child electrical use (we purchased larger system for growing family and plans to add A/C unit). Natural Gas is not offered in our area, so we use more electrical than most.
Payback period is 6.5 years based on current SDGE use. System has been producing more than expected; we are on track for $60 ($5/month charge for net metering agreement) annual SDGE bill vs. $300+ monthly bills before install.
