Yeah, we looked into solar here, but the slate roof and relatively narrow South yard prohibited it. We do have one big solar thermal panel, and I wish we'd gotten two of them side by side. Our hydro plant is 3/4 of a mile from us, at least.
Glad to see you have on hydro power. If your roof does not allow solar out here we have community solar you can buy into. Our most "famous" eco car mechanic in colorado lives in an apartment and buys into a solar farm to get equivalent power, not sure if New York has a similar option. Basically a bunch of panels out in a fiend somewhere.
PrarieLEAF being that he is looking at not being grid tied could build a huge farm but not much point unless you get batteries to store it, I almost want to introduce him to a guy in southern wyoming who has windmills and solar and the largest tesla wall installation in Wyoming (not the country just Wyoming) he as you can imagine is rural east of Cheyenne. When you have land like that you can do impressive things.
I am grid tied with Xcel so I am limited to 120% production based on my usage over year at design time. Less than two miles from my house power companies change and they are less solar friendly, have demand charges all kinds of fun so my solar EV driving friends charge at l1 and and putting in home batteries.
Home batteries: I'm building one out of used lifepo4 units that are 3.3v/120ahr each. 2P 4S gives me a 13.2v/240ahr battery, so I built two and will end up with a 26.4v/240ahr system. (6.5 kwhr)
My last set up was 2 L16 lead acid 6Vs in series with 400ahr each. (5kwhr) The new battery will be far superior due to flat discharge voltage and no memory issues.
I'm really not trying to promote where I work, just using it as an example.
3.3V/100ahr lifepo4 cells for $50/ea. $400+ some hardware would get you a 13.2v/200ahr lithium battery pack... that's some serious battery.
Used Nissan Leaf modules: 7.5v/60ahr... $110 ea, buy 4 and have 15v/120ahr for $440.
There are way more battery option available, regardless of from who.
Think outside the box folks... You can buy prebuilt things for a premuim, or you can build your own batteries for WAY less. *shrug*
