Dude I'm disabled and always home . Single father trying to save a dollar or two. C'mon I'm here for ideas and guidance not to have the piss taken. Take ya smart arse comments and fuck right off.
You ask questions in a public forum, we give you honest answers. Lots of us have thought about this and/or tried it. Especially if you are disabled (my son has serious health issues and I've been thru all of this) that it's literally impossible to be able to manually switch lights on and off, switch between solar and grid, and not miss any cycles, or be a few hrs off etc. Emergency room trips aside, I have to assume that there are just some days when your gonna be feeling like shit.
Setting up any continuous operation system you need to account for redundancy, and unless you have a trustworthy neighbor you can count on to help you in rough times, it just isn't realistic to do it manually.
Here is my advice if you are really serious about this. I have looked into a similar solar setup. All of the above advice is 100% spot on. You either need a battery system, or to be living somewhere in the US where feeding the grid is still legal (I know in Hawaii it was until just a few yrs ago). Also not sure if she is still around but
@sarahJane211 was doing something like this (but does not live in the US), maybe look at some of her threads on the subject.
Without that, here's my idea. No idea if it will work or not, but I am going to try something similar when I finally am able to purchase a home.
Setup your space with 50-75% solar powered lights. Run directly off your panels, skipping inverter and going straight into your solar circuit (not an electrician, but a good friend is a solar installer, and they now wire some residential lighting this way to save on losses. think u will need some type of DC>DC driver to regulate the voltage). On sunny days you are at 100%. On rainy days, you just have a little less light. Just like in nature. Note that I would only use this for a veg space. Flower space I would still run off mains as I don't want to affect my yield. In veg I feel like that variance is acceptable.
