"SolarCity and Best Buy have just announced a deal allowing customers to get low-cost and low-hassle solar power for their homes.
It’s what’s called a third party leasing agreement. Rather than purchasing a solar array outright, they lease the system from the provider — SolarCity, in this case. It’s just that the system is installed on the roof of the homeowner. The benefit for the customer is they don’t have to worry about installation and maintenance — the provider handles that — and there are no big upfront costs. The customer just pays the provider a set amount each month for the electricity, and that cost is usually slightly lower than the going market rate."
