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.

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 and do NOT qualify for:
- 30% Federal Solar Tax Credit (ITC)
- 10% IRA Domestic Content bonus
- 10% IRA Energy Community bonus
For an 8kW system, losing the 30% ITC alone costs ~$6,600 — far more than the ~$1,800 panel savings. Always verify panel compliance before purchasing.
Solar Sales Tactics to Watch Out For in 2026
Printable guide from EnergyTools.ai
Section 1: The ITC is GONE — Know the Facts
- The residential solar Investment Tax Credit (ITC / 25D) provided a 30% tax credit for solar installations.
- Under the One Big Beautiful Bill Act (OBBBA), the residential ITC was eliminated for installations after 2025.
- The commercial solar ITC (48E) remains at 30% for projects that begin construction before July 4, 2026, but does NOT apply to residential installations.
- Any solar installer quoting a 30% federal tax credit for a residential system in 2026 is using an expired incentive.
Section 2: Red Flags in Solar Quotes
- Expired tax credit: Quote shows a 30% federal tax credit that no longer exists for residential solar.
- Inflated savings: Projected savings assume the old 30% credit or unrealistic electricity rate increases.
- Pressure tactics: "This deal expires today" or "Prices go up tomorrow" — legitimate offers don't require immediate decisions.
- Hidden fees not disclosed: Interconnection fees, minimum bills, non-bypassable charges, and grid access fees.
- Lease disguised as purchase: You don't own the system and can't claim any remaining incentives.
Section 3: What to Do If Your Quote Uses the Expired ITC
- Ask your installer to remove the tax credit from the quote and show the true net cost.
- Request a revised quote reflecting 2026 realities — no federal residential ITC.
- Get at least 3 quotes from different installers for comparison.
