Just got done purchasing a system. In our case our base allotment was shit and we're paying tier 4 almost every month. Solar should drop our bill to around $20/month. My takeaways on the process:
- Learn the different inverter types. At a minimum, understand the difference between micro inverters and string inverters.
- Equipment prices are reasonably transparent, which gives you some insight on how much labor and profit are baked into the quotes.
- Do your own numbers. Most quotes contain bullshit ROI charts saying your system will pay off in less than 7 years. They're based on unrealistic electricity rate increases and likely over production. In our case the system we got will be closer to 10
- Haven't confirmed, but you might be able to claim at least some of the cost of a new roof on the 30% tax credit
