I don't quite understand how solar 'STCs' work. This is how I understand it...
when you buy a new solar panel system now... you get STCs... which you sell to the panel company for $X (it goes up and down). and this is given to you via a upfront discount on the solar panel system (eg. you pay $5k for a $7k system, 2k being your STC rebate/discount).
My question is now... do the power companies still buy your excess power ? I think its 8c or whatever... OR has it already been paid via the STC rebate/discount ?
