I have solar for an outbuilding to which I can't run power, and I have solar for the trailer for dry camping, and in each case I bought (not leased or rented or financed) the components and set it up myself.
Twice I looked into solar for the house, had salescreatures out both times, did a lot of reading, (starting with The Complete Idiot's Guide to Solar for your Home and branching off from there), looked at the financing side, read the reviews, and decided that the great majority was a scam. You see the ads all the time for "free solar" and "if you're paying more than $15 a month for electricity you're an idiot" and the like. But the great majority of these companies are in the same vein as the ones that want to sell you "one simple trick" to cure diabetes. The great majority are scams.
Sidebar: That goes for the great majority of "solar generators" offered for sale. THEY'RE JUST BATTERIES. Fine if a bit pricey for charging up your iphone, but forget powering your house. A friend bought one with a patriotic name as he regularly experienced outages. I sat down with him ahead of time and ran the numbers -- adding up power requirements and availability, he'd get only a few minutes on a full charge, then days of recharging on the wimpy solar panels provided, and horribly overpriced for what he was getting. But he bought it anyway. These things are designed to sell to hopeful people who don't understand electricity.
Anyway, for me it took a lot of time and was a bit frustrating, and I had to endure high pressure sales, but I'm glad I did the groundwork. It appears that I dodged a bullet.
THAT SAID, there are definite uses for solar. My trailer will run indefinitely on 350W provided by solar panels, using AGMs to store power for nighttime use, (don't get me started on lithiums -- people usually don't understand what lithium batteries actually buy you) but solutions like that require planning and knowledge. Everything in the trailer that doesn't run on propane, including the fridge, runs on 12 volts, (except air conditioning, which requires shore power) and everything is designed to use the minimum power possible.
And admittedly, I have a notion of isolating the house fridge and freezer on their own circuit, buy some deep cycle batteries, sine wave converter, soft start, and sufficient panels so that I could keep my food from spoiling if the power went off for a long period of time. And now, with companies going out of business, may be the time to look for deals on remaindered solar panels.
Addendum: Modern, self-contained wireless security cameras will also recharge off solar panels. The ones I put up have a separate panel rather than attached to the camera itself, allowing me to put the camera where it needs to be and run a line to the panel on the roof. It simplified the setup tremendously not to have to run any wires from the house to the cameras.
I guess the overall point being, solar has its uses, but if you're not knowledgeable, there's a strong chance that you will be scammed.
