Total Purchase or Plan Costs

Difference 1: Total Purchase or Plan Costs

With a cash purchase, you pay your investment in full, upfront, without any loan fees or interest payments to consider. This results in the highest upfront costs and lowest total costs.



With a loan, your investment includes loan fees and interest payments. Costs are spread out across the terms of your loan, resulting in low monthly payments but higher total costs.


With a lease, you pay a low, monthly fee for the installation and usage of solar panels, allowing you to benefit from low monthly payments without the debt.

Difference 2: Eligibility for Tax Credits and Incentives

With a cash or loan purchase, you may be eligible for tax credits and incentives, including the 30% Residential Clean Energy Credit (RCEC), that can help you recoup some of your investment costs.



The RCEC, like many solar tax credits, is designed to incentivize the purchase of residential solar. If you do not own your solar energy system—as with a lease or power purchase agreement, you are not eligible for the incentives.

Tax credits and incentives available.
