Solar Power For Residential
Thursday, May 28th, 2009
With Grid tied PV do Power companies buy your power when you are at work & supply you nights and bad weather?
Power companies incentivise your system because they get to buy your power in summer when you are often at work, kiids at school. They want the power for office building air conditioners and such. They like getting it locally from residential roofs, then at night they supply you. seemless. The meter handles the exchange. You never think about it, Your power from the Solar PV goes to your subpanel first, then out to the grid after you excess daylight power is metered to credit you. That’s why it’s a no brainer, at least in climates that get a lot of sun. Cold is good. Voltage goes up when temperature goes own. It’s not producing well in cloudy weather, and that’s why payback is much faster in sunny states, and sunny weather.
Yes.
In my opinion, every suitable artificial surface should have Photovoltaic cells on them
