Same here. A small 4.32 KW PV system producing between 600 and 750 KWH/month provides nearly double the electricity we consume. It's only been in service for 6 months but that period includes the weakest solar months of the year so the future looks good. Since we are grid-tied we still get a small electric bill ($8.11/mo.) but that is offset by a rebate pegged to our production. This month I received a check for $18.18. That allows $10.07 to be put toward our small natural gas bill.
We are making money from electricity production while spending no money and keeping a carbon footprint of zero. I'm very pleased with my investment so far. Lower monthly overhead eases the apprehension associated with retirement. I'd like to get an electric car to use all our extra watts but the Prius uses very little gas for the little driving we do that the trade would work against us. Too bad - I really like the idea but can't justify it financially.
If everything goes as planned, I should be getting gas, electric, water, sewer and trash and recycling pickup all for about $80/month. Behind food and mortgage, cell phones will be our biggest monthly bill at $124.
Doesn't matter what amps I use or whether I ever shut them off or not. Central air conditioning and free electricity take care of any concerns in that area. LED bulbs help too.
