@gtg That is really interesting you can store your power for later through your utility provider. I have never heard of anything like that before. Yeah there is about a 12% loss when converting solar to the batteries and then using it later with lithium ion batteries... even worse with lead acid.. so I can see why the fee is high.

My utility provider will pay pennies on the dollar, and has a weird clause where If I do not produce a "steady" I will get penalized. So its not really worth it to me to deal with my utility company exporting power.
