May was a lot cloudier than April - 577.5 kWh vs. 802.5 kWh in April. We still used some heat in May, so not quite down to the summer baseload of 200-225 kWh/month. The energy used pattern (blue columns below) is much smoother than the solar electricity produced pattern, which shows the variations in weather overlaid upon the typical seasonal pattern of production.
Here is the energy usage by end use:
Energy used by the Geyser heat pump water heater is beginning to drop as the basement temperature and the incoming well water temperature both rise:
Marc, I'd be interested in a post where you detail all of your data collection apparatus... this stuff is very cool. :)
