What changed for 2026

Start with the rule that drives everything else. the federal residential solar credit (Section 25D) expired for systems purchased with cash in 2026; a lease or PPA may still capture 30 percent through the Section 48E commercial credit. That is why a 2026 cash payback in San Jose reads differently than the numbers you may have seen a year ago. This is general information, not advice.

The San Jose system and what it costs

A typical San Jose system is about 8.6 kW. As a 2026 cash purchase it runs around $24,940, because the federal residential credit no longer applies to a cash buy. Through a lease or power-purchase agreement that captures the 30 percent commercial credit instead, the comparable basis is closer to $17,458 - a different ownership path, not the cash price.

Why the highest rate does not mean fastest payback

Here is the California twist. Your electricity rate of about $0.320/kWh is among the highest in the continental US, which should make solar pay back fast. But California offers no dedicated state solar credit (0%), and its net-metering rule is avoided cost NEM 3.0. Under that policy the power you export earns far less than retail, so a battery does much of the heavy lifting.

How to read your payback

Here is the honest 2026 picture for San Jose. As a cash purchase with no federal credit, the payback is about 14.0 yrs. Through a lease or PPA that captures the 30 percent commercial credit, it is closer to 9.8 yrs. The high rate helps, but avoided cost NEM 3.0 is what stretches the cash timeline.

Frequently Asked Questions

Does NEM 3.0 mean solar is no longer worth it in San Jose?

No. Net billing under NEM 3.0 pays you far less than retail for power you export back to the grid, which lengthens the payback period compared with the old full-retail rules. But high local electricity rates still make self-consumed solar valuable. Pairing panels with a battery, so you use more of what you generate instead of exporting it cheaply, is how most California homeowners recover the value NEM 3.0 took away. This is general information, not financial or tax advice.

Can I still get the 30 percent federal credit on a cash solar purchase in California in 2026?

Not on a cash purchase. The federal residential credit under Section 25D expired for systems bought with cash in 2026, so our cash cost figures already reflect no federal credit. A third-party lease or power-purchase agreement may still capture roughly 30 percent through the separate Section 48E commercial credit, but that is a different ownership arrangement where the installer, not you, owns the system. Treat those two paths as genuinely different deals, not the same price.
