Well, looks like I have not one but TWO long-planned #solar projects progressed today.
As well as fiddling with panels for the home-office solar & ordering an EcoFlow unit to connect them to, I've also deployed a solar panel inside the #allotment polytunnel to connect to a couple of car batteries. The cheap solar charger unit I had lying around for this might be a bit knackered though, it was behaving a bit weirdly, but maybe that's because I didn't have a battery connected. (I have ordered battery clamps to get those connected too.)
This panel is kinda facing mostly the wrong way at the moment, and is inside the polytunnel... I'll probably prop it up to face a better angle, but it only has to maintain the batteries which are only going to have some basic microcontroller electronics on them, a few solenoids, and maybe a 12V pump (though I only intend to run the pump daytime when there is sufficient solar supply.)
