## Critical 2026 Facts
- Section 25D residential solar ITC: **EXPIRED** Dec 31, 2025. Homeowners get $0 federal tax credit for cash/loan purchases.
- Section 25C energy efficiency credit: **EXPIRED** Dec 31, 2025.
- Section 48/48E commercial ITC: **ACTIVE**. The begin-construction window closed July 4, 2026; projects that began by then locked in the full timing pathway, and new starts still qualify if placed in service by Dec 31, 2027. 30% base + bonus adders up to 70%.
- Third-party owned solar (lease/PPA): Financing company claims 30% ITC under Section 48, passes savings to homeowner as lower payments.
- Section 30C EV charger credit: **EXPIRED** June 30, 2026 (both residential $1,000 and commercial $100,000/unit). State and utility EV-charger rebates remain.
- FEOC component-sourcing rules: ongoing (govern the domestic content bonus adder).

## Interactive Tools
- Instant Solar Quote Calculator: https://nuwattenergy.com/en/iq — homeowners enter an address and average electric bill, then see a roof-specific panel layout, system size, production, and preliminary savings range before sharing contact information. Exact preliminary economics unlock only when the visitor chooses to save the estimate; every result remains subject to site and project verification.
- Commercial Storage Feasibility Studio: https://nuwattenergy.com/en/commercial-solar/storage/calculator — starts with a bill-based value stack, then accepts CSV or Green Button interval data to screen battery kW/kWh, monthly peak shaving, published program revenue, critical-load runtime, confidence, break-even installed cost, and quote-based NPV/IRR. Results are visible before email; verified work email is used only to save a private report. Raw interval readings are not stored.

- Solar quote checker: https://nuwattenergy.com/en/quote-checker — separate review of an existing installer proposal; it does not replace the residential quote flow.
- Commercial cost and financing remain owned by https://nuwattenergy.com/en/commercial-solar/cost-guide and https://nuwattenergy.com/en/commercial-solar/financing; the site estimator does not publish generic economics before a site result and work-email verification.

## Inverter Intelligence — Independent Reliability Report
NuWatt publishes an independent, source-cited reliability report covering 16 residential solar inverter brands. Each brand carries a year-10 field failure rate, median warranty claim turnaround in weeks, an A+ to F reliability grade, and a financial-stability classification anchored to public 10-K filings, Bloomberg BNEF tier lists, and installer surveys (PV Magazine, SolarPro). Notable findings: Enphase remains A+ (~0.2% year-10 failure rate, 1-week claim turnaround); Fronius and SMA grade A; SolarEdge has dropped to a C grade with "Financially at risk" status after $1.5B+ in 2024 losses and a 12-week median claim turnaround. The full report lives at https://nuwattenergy.com/inverters/reliability-report-2026 and the same data drives the BatteryLockInForecaster tool used across NuWatt's equipment pages.
