We did one prepaid lease with Sungevity: 3KW for $8800 about a year ago. It produces 4500 kwh/year. Avg cost/kwh= 9.5 cents.
I’m doing a second regular lease with them for a 4.9KW system. I put $1000 down and have a flat $85/month for 20 years. It will produce about 8000 khw/year on average. Avg cost 8 cents.
For two other smaller rentals, I priced 3KW systems as leases from Solar city, they were in the $55/month range. They were more competitive for small systems.
