Does a solar install actually add value in 2026, or is it a liability? The answer is in the post-incentive math. I created this app to help homeowners and investors see the "Net Cost" vs. "Long-term Savings" specifically for the 2026 tax environment. It’s a clean, data-driven tool for your toolkit. No sign-ups required—just run the numbers on your latest property.

Is anyone else seeing wildly different ROI numbers for 2026 installs in the USA and Canada? The new incentive step-downs are making standard calculators obsolete. I’m a dev and a solar advocate. I got tired of explaining the 2026 math to friends using broken web tools, so I built a React-based app that runs directly inside Reddit via Devvit. It’s 100% free, has zero ads, and stays updated with current 2026 logic. I’d love for the experts here to stress-test my math.
