Started down this path about six months ago. Steep learning curve for me. Every company I've "dealt" (tried to deal) with has been as opaque as split pea soup. Customer service is absolutely NOT part of the solar industry's business model!!! So, I got a little information here, and a little information there, tried to make sense of the technical information available on the inter webs, and gradually got a sense of what was reasonable to expect and important to do when 'going' solar.
Early on, I had to come to terms with the notion that there were reasons in addition to economics that were part of the decision making. While I saw the whole affair as a place to park dollars as a hedge against inflation, my wife saw it more as a quality of life issue. I couldn't see her point at all when setting out on this path, but have come to appreciate the fact that solar power is more than just a way to "invest/save" money. More important to her were the benefits of reliability to our electrical supply, the social/moral aspects of using the sun rather than fossil fuel to power our little world, and the potential value of generating our own power should social upheaval get even closer to our lives than it already has. My neighbor, who has a Tesla solar system in/on his house, said the other day that "the day may come when we will look like the smartest people in the world." And, he's not a negative guy.
After months (!) of doing the twisted tango with the company that is represented at Costco (Sun Run), I realized the packaged/bundled deals from Tesla were very inexpensive and much higher in value than other choices. It was necessary to include storage, a.k.a. battery backup, in order to realize my wife's hopes for the project. And, the Tesla Power Wall is the best thing going in the area of storage at this time. The Power Wall has many other features that make it a clear choice to me: Multiple MPPT inputs, ability to 'program' how/when it gets and gives up power, its ability to proactively change modes when it gets weather alerts, and the data that it puts out about usage, generation, and storage level. Living in the Southwest -- and according to my wife's aspirations for going solar -- it was necessary to run the WHOLE house off the back up system. And, since the Tesla Power Wall is expandable it looked even better to me. Our HVAC is totally D.C. motor configured -- so every motor is 'soft-start' making the possibility of running the AC off the solar system possible. The Tesla system (two Power Walls) will run our 'world' for 7+ days (infinitely) independent of any power from the grid. How it does this is/was part of the learning curve.
I agree with the last post that there seemed to be a moral imperative on us to install solar since we live in a location with high angle sun virtually every day of the year. And, our system is 'big' enough to operate an electric vehicle in addition to the house should that day ever arrive in our lives.
Don't be in a hurry because there's a lot to learn and nobody will promise anything in terms of project time line. Supply chain issues make that impossible. Tax incentives may, or may not expire at the end of this (2022) year. But, one imagines they will be extended as they have been in recent years. So, if you're thinking about solar, my advice is to get busy and start learning without buying anything until you are comfortable that you understand exactly what you'll be getting.
