Other Benefits:

Maintenance Requirements:
None. Set it and forget it.
Efficiency or Sustainability Improvements:
House is 6 years old with good insulation and efficient appliances
My Motivation:
100% work from home requires resiliency. Cost of energy increasing and inflation made the solar install economically viable, even in Texas.
Advice:
Don't assume net metering is a viable option for you now or in the future. Plan your system to get to close to 100% self consumption. Do not buy a solar only system, always combine with a battery backup solution, it is a lot more expensive to add batteries later. For large systems I'd advise against Enphase microinverters, they do not have economies of scale and don't get cheaper as they get larger. Their battery solution is AC coupled, inefficient, and very expensive.
Experience with Installer:
Pick one that is willing to work with your needs and not one that is set on selling you the system or brand they're married to. The install goes quick once permits are in and the parts are obtained. Logistics and supply will slow the process down considerably, I don't think it is going to get better in the near future.
