    I've been asking ChatGPT the same thing over the last few weeks and it's drawn similar conclusions. At 40, I think getting the existing, tried and tested PV panels up is probably smarter than waiting until the alternative is ready for the mass market. Also, I'm suspicious of my municipal utility changing the rules on our grid contribution payment scheme, so if it's possible to be grandfathered in on a better scheme, I'm here for it.

      I have seen in this video from Mr. Ferrell, that the cost of installing the solar panels is $16000. I am wondering why that can be so expensive? I see that it may be complicated on some roofs. However, for a simple roof, I am not sure why a homeowner cannot just do it alone, without paying contractor. Myself, if I were installing solar panels, I would ask my niece's husband to help and give him $200. Unless there is a technical requirement that is very challenging without a professional?

        If you plan to use net metering and feed back your excess power to the grid, then your solar install would likely need to be done by a licensed electrician and then certified by the municipality. This probably differs by region, but it was the case when I previously got solar.

        You are working at height, need to know how to do the install without making a leaky roof, need to know how to work with different roofing materials, how to the electrical, wiring, grounding, running conduit.

        I think it would be great if there was at least an industry mount that roofers could install with new roofs so adding panels is easier.

        where i'm at, that would be cheap. and nobody would install just 6kw because the expensive part is scaffolding and the certified electrician, as well as the skilled work needed to install the mounts on your roof so it does not start leaking. not now and not in 30 years. good roofs here have an expected lifetime of at least 40 years.
        so yes installing solar on your roof is not hard or expensive, doing it right is.

    I've not pulled the trigger on getting a full solar install yet, I was quoted ~$40k for a rooftop system. Absolutely agree on getting as much installed as soon as you can though. There will always be something newer / cheaper on the horizon.

    I ended up getting a battery system that allows me to run my house on non-peak electricity. It came with two 500W solar panels, mostly meant for using the battery for camping. Having just that 1kW of solar on top of an arbor for the last year they've generated ~$200, which is a month's electric bill in spring or fall. The solar panel part of the system will pay for itself in 5 years. I'm probably going to buy another set.
