As far as I know, the SREC is a one-time lump sum for the 10 year period, so you're looking at one payment of $1,000-$1,800 right?
There are schemes where you can get fixed price SRECs by signing them over to a 3rd-party. The third-party then give you a fixed amount monthly or quarterly or whatever but it's a significant discount on the auction price.
There are also companies that will give you a lump sum for your 10-years of SRECs up front but like all 'need cash now' schemes there is a significant discount.
