How do solar panels work in the sense of billing? Do you not have an electric bill? Are you just paying for the panel itself?
In: Engineering
The solar panels are attached to your house after the meter.
Any energy flowing to your house from the panels does not tick the meter, so you get it for free.
If your solar panels are providing more energy than your home is using, then the energy runs backwards through the meter, running it backwards. If at the end of the billing cycle, your meter is before where it started, you get credited for that energy you provided to the grid at a supplier rate (slightly less than you would have paid for that same amount of energy). You are still billed a delivery charge, because that charge is for the maintenance of the grid itself.
