Solar Financing Comparison Calculator
Compare cash, loan, and lease financing options for solar installation
About this calculator
The Solar Financing Comparison Calculator helps homeowners evaluate the three main solar installation payment options: cash purchase, solar loans, and solar leases. This tool analyzes upfront costs, monthly payments, tax incentives, and long-term savings to determine which financing method offers the best return on investment. By comparing total costs, payback periods, and lifetime savings across all three options, homeowners can make informed decisions that align with their budget and financial goals.
How to use
Enter your solar system cost, available cash, loan terms, and lease details into the calculator. Input your local electricity rates, tax incentives, and energy usage. The calculator will generate a side-by-side comparison showing upfront costs, monthly payments, total expenses, and projected savings for each financing option over 20-25 years.
Frequently asked questions
Which solar financing option saves the most money?
Cash purchases typically offer the highest lifetime savings, followed by solar loans, then leases. However, the best option depends on your available capital and tax situation.
Do solar loans include tax incentives?
Yes, with solar loans you own the system and can claim federal tax credits and local incentives, unlike with solar leases where benefits go to the leasing company.
What's the typical payback period for different financing options?
Cash purchases usually pay back in 6-10 years, loans in 8-12 years, while leases may never fully pay back due to ongoing monthly payments.
