Sometimes, when I go to learn something new, it feels like I've hit a brick wall. Terms feel slippery, concepts feel disconnected, and it's hard to see how to apply new knowledge to my life. That's kinda what learning about solar power is feeling like, so I had the thought to live blog as I read the books, to hopefully force my brain to process the information. Come with me as I learn the basics from library books!
I'd really like to have a small solar set up to help in the case that the power goes out. I don't want to run my whole house, I mean I would, but I think that is out of my budget and skill range.
I was thinking enough to run a electric burner and charge phones for when the power goes out in the winter, or enough to run a fan for a corsi-rosenthal box and a mini-fridge if the power goes out during a combined heat wave & wild fire smoke event. I've heard that ac units have a power usage spike when they first start running that makes them hard to power off smaller than whole house set ups, so I was thinking that I could use the fridge to cool water to then use to cool our bodies.
I'm going to start reading 'Off Grid Solar Power' by Mark Kessler.
Hey I'm going to barge into here with some unsolicited advice hopefully that is OK:
LOTS of electronics will have an initial large spike. It may depend on whether or not they have a compressor. Our deep freezer also caused a large spike when first plugged in. Electric stoves tear through electricity, you might consider an emergency camp stove or even a solar oven, at least for back up.
Things marketed to Americans such as Jackery or Powerwalls are designed to be easy to use and they are! But they're also very expensive for what one gets. Our small Jackery set up served us great though for many weeks when we had zero power due to Helene.
Things not marketed as strongly to Americans can be much cheaper but can also require either being willing to take a chance on quality (it varies, we've definitely picked up some off brand solar panels that did not generate nearly as much energy as they claimed) or being stronger in the DIY category.
Talk is that China overproduced solar panels this spring in particular because they were counting on Biden's amazing environmental bill to fund a huge amount of green infrastructure in the US. Trump tore that up and the Chinese companies have been left with excess product - prices are crazy cheap. There's also rumors that the Trump admin is going to start adding tariffs to Chinese inverters. So basically this is a great time to get something, even if it's small.
This is the company V went with for our set up after we decided to upgrade after Helene, for most of our batteries and the inverter. The lady who owns it is very nice and their prices are extremely reasonable. Also, their products aren't a "walled garden" so you can use whatever solar panels you like, add on additional things to the system that are a different brand, etc.
With everything going on in the world right now, if I could, I'd expand our system, add on an EV charger, and get a used EV. But I don't actually have a head for electricity - that's all V. But there's 2 different skill sets involved, one is just setting up a system, and other is actually designing the system.
Oh! Just so you know, whatever a solar panel claims to produce? That's only under the most ideal and perfect conditions and probably never. Expect to get a lot less, and just how much less depends on many factors, where you're located on the planet, clouds, trees, how the copper wires are feeling that day, etc. But 25% less than what is claimed is pretty common. So if it's a 200W panel plan on it only producing ~150-180 at best, don't count on that 200W, at least that's been my experience.
(If I was just trying to keep things simple and I was willing to budget $1k and didn't have V the electrical whiz in my life, I'd probably be seriously looking at this Jackery setup + another of their solar panels. That 1500 W output will really get one far.)
One of my favorite solar references is "Do It Yourself 12 Volt Solar Power". It's written as if people are limited to using recycled/repurposed equipment. Lots of how too's for direct solar applications.

I'm also in the process of gathering items needed for making an Insulated Solar Electric Cooker. This has an added bonus for me, as I live in a desert and would be able to avoid heating up the house by cooking outside.
