Did you diy a roof install? I’m really looking into this as I live in the southeast, but I’m getting ridiculous quotes (60k for a 10kw system with two power walls).
For the system I'm working on now I have around $10k into the hardware if I'm not mistaken. There's plenty of skill and time that goes into designing the system, custom wiring, etc. I also had wuotes around $50k-60k. There's no way in hell I can justify 80% of the price in labor, very happy I happen to live in an area where I can install this myself without running into regulatory issues.
That site is pretty hit or miss with stock since it is all repurposed equipment, but if you happen to catch the right equipment going by you can get a really good deal for anything DIY.
I was about to order a pallet of new lithium cells from one of the US resellers when the batch of repurposed automotive cells popped up. When I was pricing them out I could get the cells and a DIY BMS for around half the price as rack batteries often used by DIYers today. There's more work involved in putting the cells together yourself, but it is nice knowing how it works and how to fix it should a cell fail.
You’re getting terrible quotes because the construction industry has been doing phenomenally the last several years.
I built a contractor search product to compete with HomeAdvisor because the quotes were such a joke. I don’t use it as much as I did when I first built it though. I now know more about residential construction than some contractors I’ve worked with.
I’ve saved literally tens of thousands of dollars.
We’ve been operating privately in Arizona by invitation. It’s ready for general availability, but not terribly useful to people outside of AZ right now.
We’re ready to start rolling out to other states and include their registrar of contractors’ directories.
