I'm currently trying to dive into solar energy but feeling a bit overwhelmed with all the technical jargon. I've researched scoping and sizing, but I still don't fully grasp the terms and details being discussed here. I have a two-story, 2600 sq ft house in central Alabama with some power-hungry devices like servers and computers, plus normal appliances and a deep freezer. My utility bills average around $400-500 each month.
I'm looking for a DIY solar setup to be self-sufficient and save on those costs. Ideally, I want to design a system that I can install and forget about for the next 30 years. I've calculated that I need about an 18kW system with enough batteries to last for three days, but I'm unsure how accurate my estimations are.
I have some specific questions about design choices, equipment sizing, and what brands to consider, especially since I don't want to make mistakes in my DIY project or end up with junk equipment from online retailers. I'm particularly interested in hearing if there are any better resources or kits out there that can help me along the way. Any insights or recommendations would be greatly appreciated!

Before you go full solar, consider an energy audit. Upgrading to a heat pump could cut your monthly bill significantly, and tackling energy loss in your home is crucial. Old fridges can really drain power, too! Make sure you’re using the right electricity-saving tactics before sizing your solar system.
I think starting with a small project, like adding solar panels to a shed, is a fantastic idea! It costs me under $800 to set up lights, run my washer, and power some tools. It was a brilliant way to learn the ropes before tackling my house. You’ll get some hands-on experience that’ll help with bigger projects.
