A little update on our PV system

By | October 31, 2006

It has already been a year since we generate a lot of our electricity on our roof. Starting in October 2005 we got our new meter. So this years October bill was the time when PG&E did the true-up over the year.

We did not have to pay for any used electricity;-) We only payed for the fixed connection costs (basically that PG&E runs a wire to your house and that they provide the meter) something like six dollars per month.

Our PV system produced around 5080 kWh over the last year, that’s more than the estimated 3700 kWh;-) Our household used an additional 1040 kWh from PG&E over the year. I know, other houses use that in a month;-)

Overall I think we saved something like 720 dollars on electricity costs and we avoided around 10,000 pounds of CO2 from coal firing power plants.
