Renewable Energy Project Financing
A wide variety of financial strategies have emerged across the country to aid owners in raising the necessary capital for installing a PV system or in spreading the cost out over the life of the system.
In New York City the most common method for financing a system is paying with upfront capital or cash. Many residential installations can be funded using a home equity line or by refinancing a home mortgage. For commercial systems (and some residential systems), it may be worth exploring signature loans, equipment leases and commercial loans with your bank.
