Solar Production - April 2009

April is behind us, May on the horizon. As we close out another month of being a solar-powered home, I thought I would share our production stats:

Last day results:

The longer days are giving us between 60-63 kWh per day. This is roughly two to three times our current usage, with all the surplus being banked with the utility as credits for upcoming months. The lifetime total is since the system was commission in February. We're into our fourth megawatt of generated power!





This next chart represents the daily production for each day in April. You can see a few days where we were at about 40 kWh for the day, these were cloudy days, yet we still made more than our usage for the day. The vary short bar was a day of clouds, rain and dark skies. Not bad overall!





Finally, here's the clip from the utility bill. For the second month now, our bill is $8.54, which is the charge to be a customer (administration, billing and meter reading fees, plus all the taxes). Our credits of kWh last month were 349, this month we are at 955, nearly a megawatt of credit. The bill for this month last year was $128. Stay tuned for the next update!
