A Power Purchase Agreement (PPA) is an alternative way to finance a home solar system. In this agreement, a homeowner pays for the electricity that their home consumes from the energy produced on their rooftop solar. The system is installed by a solar contractor for little to no upfront cost.
Under a solar PPA agreement, the solar developer retains responsibility for operating and maintaining the solar energy system over the life of the contract. They'll perform annual inspections, repair any damage, and monitor the system to ensure its performance is continually optimized.
The total cost over the service life of the system is amortized to give a levelized cost per year. In the PV System Cost Model (PVSCM), the owner's overnight capital expense (cash cost) for an installed PV system is divided into eight categories, which are the same for the utility-scale, commercial, and residential PV market segments:
Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors are evaluated each year.
Power Purchase Agreements terms vary from deal to deal. Some key differences are fixed vs escalating rates, pre-payment options, and buyout options. We''ll elaborate on each of these features below.
