Solar Performance - June 2016

After last month's poor performance I was worried that June would turn out similarly poorly. While the numbers didn't turn out as well as last year they were a good improvement over May and lined up very well with the estimate for the month.

Individual panel performance was also pretty normal this month, with every panel within 5% of the average. The east-facing panels had noticeably lower efficiency at the end of the month when we had a string of days that were heavily overcast in the mornings and sunny in the afternoons and evenings.
