I really wanted to do this but... Got the Tesla Roof Proposal today and it’s a bit more than the maxed out $34k on-line guesstimate for my home. A big chunk is that they upped it to two Powerwalls and put solar on the garage to up the total production. But wait there is more. Asbestos Removal $12,100.00 (Two heat pipes for the water heater and stove.) Deck Replacement $3,200.00 (Thought the 1x6 wood planks would have been a plus but they said it's too uneven. I guess but I'd worry about saggy plywood as well. Lead Paint Remediation $7,500.00? (I have to get it done on me own.) That is like $20k before they even put the solar roof on. I don't totally fault them but they really could have told me this when they did the 4+ hour site survey almost 2 months ago. It's $90,284.38 before the $5-$15K Lead Paint Remediation. Please check my math but it looks like (if every little thing goes to plan) it would be 43 years to break even. That is using full 10,874kWh posable production every year. If I used as much as last year every year it would take 66.4 years! Just in my head on the phone with them I said I’d be dead long before that. I may have gone for it without the Powerwalls and the $20k in roof prep. Even then it's 26 years to break even. If I just did solar cells on the house I don't think I'd make enough. Poop!
