Solar Power Update


The electric company installed a new power meter last week in response to my solar power installation. One of the really neat things about the old meter was if the air conditioner wasn't running and the sun was out, the wheel on the meter would run backward because the solar panels were producing more electricity than we were using. The same happens on this new meter but it is harder to see, there are three black dots below the digits that blink on and off either from left to right or right to left depending on weather we are using more than we are producing. We hit a solar electric milestone today. Our total electric production since installation 38 days ago is now just over 500 Kwh or just over 13 Kwh a day. According to the inverter, that production has saved over 850 pounds of carbon dioxide. My last electric bill was 468 Kwh lower than the bill at the same time last year so the system looks to be producing 25% of our usage during the heat of the summer.
