Pardon the stock image. It won’t let me post without one. Curious if anyone here has built or researched a diy balcony solar setup. I’m new to solar, so this seems like a good small scale project to learn on.
If you have built one, what equipment did you use? How did you decide on panel wattage?
Having battery storage is the most expensive part of any off-grid system. Without it, you obviously dont need batteries, but you can also get rid of all the battery management stuff, charge controlling, inverters, etc.
Direct attic fan sounds great because you need it the most when it’s the most sunny.
It would be cool to do a direct solar powered hydroponics or pond project, where you just pump all the water to a reservoir when you have sun, and let it drain back 24 hours a day.
I figure batteries are their own thing and useful on their own. Technically if the panels provide the minimum your unit uses for fridge and such non is needed but batteries to me is about having blackouts and being able to still function as normal for enough time to get it sorted. Granted that can be a long time but like an hour can cover the majority of outages and as it gets longer you get more but its sorta one of those things where the longer it is the less often its going to come into play but then you have where if the panels get you more than you need then you can pay less at night to. For awhile anyway.
