I was still quoted 40K CAD. 20 year ROI. Not feasible for me.

how much solar generation capacity and battery storage are u seeking ? where i live, a 2kw solar installation without battery (grid-tied system ?) costs about 3k$. system pays itself in 4 years and rest of existence is powered by free energy. want batteries ? a 1kwh costs about 300$. where i live 4kwh/day is more than enough, sometimes 10kwh/day in extreme heat/cold. but i guess american needs could differ (30kwh/day maybe?). to recharge 30kwh batteries, u would need extra solar capacity (maybe 7kwc ?), and that would run at 9k$, add 30kwh batteries ? another 9k$.. idk what the 50k CAD are for

15.75kW and an inverter, installation in there too. 41k - 5k gov rebate. Too rich for my blood.

16kw/0.4=38 * 100$= 3800$(usd). 1700$ for a 16kw Growatt inverter. Extra 5k$ for breakers and copper lines etc (total=10500$). Still, idk what the rest of 20k usd are for (40k cad= 30k usd). Yea, seems kinda too much. Is solar having a lobby now ?

It was July last year so maybe the prices were just that much more insane then
