alt Hacker NewsHere's the tool I use for estimating solar performance: https://re.jrc.ec.europa.eu/pvg_tools/en/#api_5.3
It's also includes historic weather patterns and has some simple modeling tools built into it that can help predict how well off grid, grid tied and hybrid solar systems will perform. So far I have found that it's predictions map very closely to what I've experienced on the ground with my solar array.
I put 7.2kw on my roof in Canada. Tight valley, tons of snow.
You know what I learned about all the projections and estimates?
It’s a complete waste of time . Panels are so cheap now just slap up as many as will physically fit and get on with it. Everything else is a waste of time.
Over their 25+ year lifespan I’ll profit $25k-$30k.
It’s the no brainer of all time.
As soon as my garage build is done I’ll cover that roof in another 8kw of panels too.
