Thought I’d provide an update on this system. It’s working great, and I have had no problems to date.
Our meter that is read for billing reads 40 kWh. That means we’ve used a total of 40 coal-fired kWh in four months. This morning, our cumulative production was around 2080 kWh, meaning on average around 500 kWh/month since installed. Of course, I’m expecting this production rate to drop significanly over the shorter days of winter.
I think what put us over the “0” mark was the use of the AC for a couple weeks (parents complaining about heat when they visit) and the use of the dehumidifier in the basement.
I am happy with the decision to install the pv system, even though our $/kWh is aobut double that of buying coal power off the grid. It has also really made my family consider what applicanes we use and when. We are definitley making better use out of our clothes lines, for one.
For those of you on the fence, if you can afford it, take the plunge!
