Energy decisions are too expensive for hidden assumptions. Every active tool is designed to make its inputs, limits, and supporting documents easy to find.
Open the source ledgerUtility tariffs, ratebooks, agency guidance, and program terms come before summaries or sales claims.
Inputs and assumptions stay visible so you can see what changes the result instead of trusting a mystery number.
Tools display when their source set was checked, and outdated calculators stay out of the public directory.
Current reference points
Our active calculators reflect these important 2026 facts. Open a tool to see the full methodology and source links.
New 2026 residential solar and battery installations use a 0% federal Section 25D credit.
APS winter super-off-peak is $0.03495/kWh on qualifying weekdays; there is no summer super-off-peak tier.
APS Storage Rewards uses $110 per average delivered kW, not a flat battery rebate.
SRP E-27 combines three seasons with progressive demand tiers and matching-period solar exports.
Before you calculate
No. AZ Energy Hub is independent. The intended funding model is display advertising, which is currently disabled during recovery. We do not sell installations, collect contractor leads, or earn product commissions.
No. They estimate the core charges described on each tool. Taxes, adjustors, riders, meter details, and account-specific charges can change your final bill, so compare the result with your utility statement.
Each calculator shows its review date and links to the official tariff, ratebook, program page, or federal guidance behind its assumptions. The source ledger records the effective period and check date for every material source.
No. The Section 25D Residential Clean Energy Credit ended for property placed in service after December 31, 2025. Our calculators apply a 0% federal credit to new 2026 residential installations.
