Misinformation about solar panels is common, and some persistent myths can lead homeowners to make poor decisions about whether solar is right for them. The most damaging myths involve outdated tax credit assumptions, exaggerated cold-weather concerns, and inflated home value claims — all worth correcting with current data.
Myth 1: The 30% Federal Tax Credit Still Applies to Homeowners
Section 25D, the residential solar tax credit, expired December 31, 2025. Homeowners purchasing systems in 2026 and beyond cannot claim this credit. Only Section 48E (for installers offering leases/PPAs) remains active through 2027 — meaning the tax benefit now flows to the installer, not the homeowner who owns their system outright.
Myth 2: Solar Panels Don’t Work in Cold Weather
Solar panels actually perform slightly better in cold temperatures due to their temperature coefficient — panels lose efficiency as they heat up, so cooler ambient temperatures (with adequate sunlight) can boost output compared to hot summer conditions.
| Myth | Reality |
|---|---|
| 30% ITC still applies to homeowners | Section 25D expired Dec 31, 2025; homeowners no longer qualify |
| Panels don’t work in cold weather | Panels are actually more efficient in cold vs. hot temperatures |
| Solar always increases home value dramatically | Owned systems add value (~$4/watt); leased systems often don’t |
| Solar panels require constant maintenance | Minimal maintenance needed — occasional cleaning, no moving parts |
| Solar doesn’t work on cloudy days | Panels still produce power in diffuse light, just at reduced output |
Myth 3: Solar Always Dramatically Increases Home Value
Owned solar systems do add measurable value (studies suggest roughly $4 per watt in many markets), but leased systems typically don’t provide the same boost since the buyer inherits ongoing payment obligations rather than a paid-off asset.
Myth 4: Solar Panels Require Constant Maintenance
Modern panels have no moving parts and require minimal maintenance — occasional cleaning and periodic inspection is typically sufficient, with most warranties covering 25+ years of expected performance.
Myth 5: Solar Doesn’t Work on Cloudy Days
Panels still generate electricity in diffuse light on cloudy days, just at reduced output (often 10-25% of clear-sky production) rather than zero — a common misconception that leads some to underestimate solar’s viability in less sunny climates.

Frequently Asked Questions
Does the 30% federal solar tax credit still apply to homeowners?
No — Section 25D expired December 31, 2025, and homeowners can no longer claim it.
Do solar panels perform worse in cold weather?
No — panels are actually slightly more efficient in cold temperatures than in extreme heat.
Does solar always increase home value significantly?
Owned systems typically add value; leased systems generally don’t provide the same boost.
Do solar panels require a lot of maintenance?
No — they have no moving parts and require only occasional cleaning and inspection.
Do solar panels stop working on cloudy days?
No — they still generate power in diffuse light, just at reduced output.
Is the federal solar tax credit gone entirely?
Section 25D for homeowners is expired, but Section 48E remains active for installers offering leases/PPAs through 2027.
Should I still consider solar without the 25D tax credit?
Yes — solar can still offer meaningful long-term electricity savings even without the homeowner tax credit.
