  • May performance

    May was a warm and rainy month. (52% less heating degree days than April, 7% less sun). This partially resulted in 20% lower energy usage in May. We only used 4.8 kWh for space heating. Our daily average usage was down 23% from April. We generated a 558 kWh surplus this month, our third surplus month in a row.
