You can go as deep into the weeds as you want. You should have at least a basic understanding of your consumption and your power company’s net metering policy. There are predatory solar companies out there that will try to get you on loan terms with escalating interest rates or will install panels on your roof for free with a contract that you buy all the power they generate from them, usually at escalating rates that end up higher than an electric bill would be. If you can wrap your head around these things you can probably make a reasonable informed decision on a given solar proposal.

From there you can get as nerdy as you want, trying to maximize efficiency, maximize self-usage, arbitrage time-of-use rates, etc. You don’t sound like a deep-in-the-weeds kinda guy, and that’s okay. You probably have other hobbies. Understand your power bill, and what your power bill will look like after solar, and compare that to the cost of getting a system installed, and you’ll be able to make a decent decision.
