PV panels are a slow payback, they would eventually 'pay for them selves' ,it would take 10 years or longer if they are grid tied.
Having the panels for assist is a great idea, not needing batteries is a plus, making the initial investment less. It can be sent with the right system and a dc/ac converter to the hydro meter, as i understand it..

I priced cinder blocks and rigid foam.
I still need to find the right roof, i am thinking a low angle Hip roof or a flat roof with steel trusses.


22x50 house - 1,100sq.ft 9ft. walls
1400 blocks @ $2.50- block = $3,500
for split faced block = $4,200

Rigid insulation- Durafoam 4'x8' x 1.5" R value R6.25 per 1", 40 pieces needed x 5 layers = 200 sheets x $20 each =$4,000 for R 46.875 insulation.

The insulation was not as expensive as i had thought it is affordable, even with 200 sheets of it.
