When financing your photovoltaic roof, you've got several options to evaluate. A cash purchase offers the highest long-term savings, while home equity and solar-specific loans provide lower interest rates and longer repayment terms. In fact, there are two types of zero-down solar loans designed with the tax credit. . Taking out a solar loan is one of the most common ways to finance a solar energy system, but you can also finance your solar energy system with other types of loans, such as a home equity loan or HELOC. Buying, leasing and Power Purchasing Agreements (PPA) are the most popular financing options.
