January 2015 Solar Production – 490kWh and 2014 in review

Here are my solar production numbers for January. 490kWh (at inverter). 489kWh (at Dominion meter). PVWatts estimate was 505kWh. Cumulative production as of Jan 31 is 7565kWh (7529 at Dominion meter). More details here.

In 2014, from Apr to Dec, the system produced 6796 kWh (measured at inverter), 6763 kWh (measured at Dominion meter) compared to a PVWatts estimate of 5767 kWh. Since the system went live in March it produced enough power to pay for over 8% of its cost (after the expected Federal rebate).
