Prepaid lease: The amount shown in the header is the prepaid lease payment, not the actual price of the system. In a prepaid lease, the homeowner pays $56,332 once, upfront — no monthly payments — and the leasing company keeps ownership of the system and claims the incentives, including the 30% ITC. The savings from those incentives are passed on to the homeowner, which is why it is priced way below the market price. If the homeowner bought the system instead, they would have paid about $80,474, estimated.
