thanks for putting up with me guys.. I understand i did not provide all the info but it took me a while to figure it all out, i think:
1. Its a PPA where I buy per kwh from tesla and all the overage NEM from PGE
2. last year the system produced 1700kwh (although its rated at 3200) so last year the owner paid tesla $289. (1700*.17)
3. on top of it, since he used way more then he produced he paid PGE $1,633, which was charged at roughly .32/kwh
so there seems to be a significant saving by going solar at least today. assuming energy costs stay flat there is a savings of roughly $2600 over 14y just going solar. (i understand that costs will not stay flat, but if they go up roughly 3% every year, it should stay the same.
issue is the
1. solar does not seem to be working at full capacity. When the sale closes i can have tesla support come out and take a look.
2. the energy it makes does not come close to covering the homes energy costs.
I expect my energy use to be significantly less than the current owners but it probably wont cover my use either. my estimated use 4000kwh per year
Even with the current system only producing 1700kwh/ year, my savings over the next 14y will be roughly $2,600 over just going directly with PGE.
So it seems like buying out the lease is the best bet to lock myself in to .17/ kwh price. But if i plan to stay there roughly less than 8y, just continue the lease month to month (with 3% yearly hikes i will be paying roughly .27 per kwh at the end of the 20y lease period if i am still there which is still not bad considering PGE costs will be much higher by then)
I think my calculations are roughly correct.
