Isn't it necessary to have the grid as a backup consumer? What happens if you over produce solar energy, but don't have the necessary means to dissipate it?

- nickthemagicman 9y agoI assume there's battery systems in place.
- rahible 9y agoIt looks like FPL has a Net Metering program, which a lot of power companies offer. In short, you get credits on your bill for the power that goes back into the grid. It used to be that some power companies actually write you a check. https://www.fpl.com/clean-energy/net-metering.html https://www.fpl.com/clean-energy/net-metering.html
- yardie 9y agoIt's not necessary. If you produce more than you use consistently then a good sized battery bank may be all that you need. A lot of new home appliances are so energy efficient they are starting to see use on sailboats. Solar cells can produce at load. It's not like panels that aren't connected are melting down, like nuclear.
- Filligree 9y agoSolar panels get less efficient as voltage increases, hitting zero at a reasonable point. This is very convenient, since all you need is a buck converter in the battery charger and any unused power can be ignored. The power still exists, of course. It just ends up heating the panels, which are fine with that.
