You’ve basically told us that solar panels will not work well for you.
If you are serious about personal electrical generation, can you tell me about the wind patterns, it sounds like that would be more practical for your area. That, industrial batteries, inverters and a back up generator can keep your lights on if the SHTF.
We get tons of wind, of course it does vary from year to year. We already have a windmill. We are at the top of a hill with nothing blocking the wind. The windmill averages about 1/4 of our electricity but, on windy days it makes it all plus some. We are probably going to do a battery back up. My brother in law owns a recycling business(code for junk yard but he doesn’t like that name.) He just acquired 25 batteries from the state for recycling, they are near new along with a converter. The converter is older about 10 years old. We can get the batteries dirt cheap but we need a good converter.
