Solar Surcharges & Hidden Costs Calculator

Solar salespeople love to quote you the "gross savings" — what they don't tell you are the fixed charges, demand fees, grid-access surcharges, and non-bypassable costs that stick around even after your panels are installed. This calculator reveals the true cost of going solar.

Tax Credit Verification

ITC Status Check

Is your solar quote using the expired 30% federal tax credit? The residential solar ITC (25D) was eliminated under the One Big Beautiful Bill Act (OBBBA) for installations after 2025. Enter your quote details to check.

Panel Compliance: A Hidden Cost Trap

Cheap panels from South Florida warehouses (Mission, JA, Canadian at $0.37/W panel-only) may seem like a great deal, but they are non-AVL/non-DomCon compliant. Note: the residential 30% solar tax credit (25D) expired Dec 31, 2025 — no residential federal credit is available regardless of panel compliance. For commercial projects pursuing the 48E ITC (construction begun before July 4, 2026), non-compliant panels do NOT qualify for:

  • The 30% commercial ITC under 48E
  • 10% IRA Domestic Content bonus
  • 10% IRA Energy Community bonus

Always verify panel compliance before purchasing — and beware any installer quoting a 30% residential tax credit in 2026, as that incentive no longer exists.
