that's great you produced more than expected.
so for your SRECs, instead of you earning them, then selling them, is it that your installer purchased future generated ones from you for 5k? so whatever you generate, they actually collect, and they sell under the old program?
the +3500 was my fudge factor for not understanding how SREC works.
basically the math we did was the first set to 6,095. assuming 15 years, selling SREC at the block 3 fixed allocation rate of the current program (lowest) - although he made it sound like i could collect these all up front. he is a newer guy to solar particularly in the IL market though. i like a big lump up front and not having to worry about it.
BUT
my understanding now is IL isn't just going to give me 15 years of these when i flip the switch - it's going to give me them after power is produced, and i will sell them over time. so over 15 years - i think i'd be getting 7.17 kW * 15 years * $67 (block 3 pricing) = $7,205 or someone will purchase the rights to these today for say 5000.
the latter is more compelling because
1. instant cash
2. life is simple
3. avoid complexity when selling home
4. avoid complexity if new homeowner adds 2 panels
etc. so my +3500 was basically to say instead of 7205 savings today... someone will buy my future SREC for 3,705; so i'll only discount my price that much, for conservative math.
if this is actually how it works, it seems if you plan to stay in your home, you're better off to just hold on to them rather than sell them today. i wonder if it's even a compelling investment to buy other people's; SRECs (??)
