March 2009 PV & EV Report

March 20th was the Vernal Equinox. There are now more hours of daylight than darkness each day here in the northern hemisphere, an important milestone on the solar power calendar. And our March results show this, generating 64% more energy than Feb.


You can see in the sunrise time chart below, that here, at 47 degrees north, the first 12 hours of daylight actually occurred two days before the equinox. And it was a great day for solar production; the 18th was one of the better days of the month, out performing the Equinox by a factor of 3. 

The 18th also happened to be the day the pond water temp went above 50 degrees F, so now the Koi are out of hibernation and demanding food. 

Days of note: 

3/18 (first day w/ 12 hour of daylight) = 15 kWh
3/20 (Vernal Equinox) = 5 kWh
3/29 (highest March production day) = 17 kWh

Solar Production: 

March total = 274 kWh
Peak power = 3.1 kW on 3/22
Total Energy Production since power on = 4.5 Megawatts

March EV driving

As for my EV driving. I logged 486 miles in the Chevy s10 Electric. This used an estimated 340 kWh of electricity. 

The solar panels 274 kWh were not enough to fully fuel my 340 kWh of driving this month. It should be close in April and this summer will wipe all deficits away.
