Solar leases and power purchase agreements (PPAs) are two 3rd-party ownership options that allow consumers to install solar energy systems without the upfront cost. Solar PPAs and leases allow non-profit organizations with no tax liability to take advantage of tax-related incentives, such as investment tax credits and accelerated depreciation.
What is a Solar Lease or PPA?
A solar lease is very much like a car lease, where you lease the equipment for a set period of time and benefit from the electricity or heated water it produces during that lease period. A power purchase agreement is similar, although with a PPA you only pay for the energy your solar system produces. It’s like paying for a car by the mile. In both cases, you’re essentially hosting a solar power system on your roof that is owned by a 3rd party and enjoying all its environmental benefits with little or no upfront payment. The PPA or lease payment is typically structured in a way that the power generated by the system costs less ($/kWh or $/therm) than that of the local utility company.
When considering installing a solar system on your property, the Department of the Environment recommends obtaining at least three bids before making your selection. There are important considerations for home or building owners who are considering a solar PPA or lease, because a third-party leasing or PPA provider will own the system.
