Incentive Calculator
Calculate Your Total Solar Incentive Savings
The math is compelling: most Tucson homeowners pay $150 to $300 monthly for Tucson Electric Power service. A financed solar system typically costs $120 to $220 per month with $0 down, creating immediate positive cash flow. You’re trading an expense that increases annually (rising TEP rates) for a fixed payment that ends in 10-25 years, after which you enjoy virtually free electricity for the remaining life of your system.
Solar financing options have evolved dramatically. Today’s products offer competitive interest rates (2.99% to 6.99% APR), flexible terms (10 to 25 years), and seamless application processes with decisions in minutes. Whether you prefer ownership through loans, want to leverage home equity, or need budget-friendly lease options, there’s a financing path designed for your situation.
Timing Considerations
When to Go Solar to Maximize Incentives
The 30% federal tax credit remains at its current level through 2032, giving Tucson homeowners several years of maximum savings opportunity. However, waiting has costs — every month you delay solar is another month paying full TEP electric bills instead of generating your own clean energy.
From a financial perspective, installing solar sooner rather than later typically provides better returns. TEP rates increase 3-5% annually, meaning your baseline electric bills (and thus your solar savings) grow each year. A system installed today saves more money over its lifetime than an identical system installed in 2030, even though both qualify for the 30% credit.
Arizona’s property and sales tax exemptions have no scheduled expiration and are unlikely to change given strong legislative support for solar. However, TEP’s net metering program could be modified in future years as more customers install solar. Installing now locks in current favorable net metering terms for the life of your system.
