Solar energy has gone mainstream, but myths and misconceptions still prevent many homeowners from making a decision that could save them tens of thousands of dollars. Some of these myths are outdated (true 20 years ago but not today), some are exaggerated, and some were never true to begin with.
This guide addresses the most common solar myths head-on – with facts, data, and honest answers.
Myth 1: Solar Panels Do Not Work in Cloudy or Cold Climates
Fact: Solar panels work in every U.S. state, including cloudy and cold ones. They produce electricity from light, not heat. Overcast days reduce output but do not eliminate it – panels still produce 10–30% of rated capacity on cloudy days. And panels actually operate more efficiently in cold temperatures.
Germany – cloudier than any U.S. state – is one of the world’s largest solar energy producers. Ohio, Kentucky, and South Carolina all receive 4.0–5.2 peak sun hours per day, which is more than sufficient for strong solar returns.
For the full story, see our guide to solar in clouds, rain, and snow.
Myth 2: Solar Panels Are Too Expensive
Fact: Solar panel costs have dropped over 70% in the past decade. After the 30% federal tax credit (and 25% state credit in South Carolina), a typical residential system nets out to $10,000–$20,000 – comparable to a used car or kitchen renovation, but with a return of $35,000–$75,000+ in lifetime savings.
With $0-down financing, most homeowners can go solar with no upfront cost and a monthly payment lower than their current electric bill – meaning they save money from month one.
See our solar panel cost guide and financing guide for the real numbers.
Myth 3: Solar Panels Damage Your Roof
Fact: Properly installed solar panels protect your roof. The panels shield the underlying roofing material from direct sun exposure, rain, and hail, which can actually extend the life of your shingles. The racking system is mounted to structural rafters with weatherproof flashing and sealant.
Roof damage from solar panels is almost always caused by poor installation quality – improper flashing, missed rafters, or inadequate sealant. This is why the installer’s workmanship and roof penetration warranty matter enormously, and why Gold Path Solar uses in-house crews and provides a comprehensive roof penetration warranty.
See our installation process guide for how proper installation works.
Myth 4: Solar Panels Require Constant Expensive Maintenance
Fact: Solar panels have no moving parts and require virtually no maintenance. Rain cleans them naturally. System monitoring detects issues automatically. With microinverters (25-year warranty) and Tier-1 panels (25-year warranty), there are no expected maintenance costs for the life of the system.
The total ongoing maintenance cost for a well-designed solar system is realistically close to zero. See our maintenance, lifespan, and warranty guide.
Myth 5: Solar Panels Decrease Home Value
Fact: The opposite is true. Studies from Lawrence Berkeley National Laboratory and Zillow consistently show that homes with owned solar systems sell for a 4–7% premium over comparable homes without solar. On a $300,000 home, that is $12,000–$21,000 in added value.
The one caveat: leased solar panels can complicate home sales because the buyer must assume the lease. Owned systems add clear value. See our solar and home value guide.
Myth 6: “Free Solar Panels” Are a Real Thing
Fact: There is no such thing as free solar panels. When someone offers “free solar,” they typically mean a solar lease or PPA where a third party owns the panels on your roof and charges you a monthly fee. You do not own the system, do not get the tax credit, and may pay more over time than you would with a loan or cash purchase.
$0-down financing is real and legitimate – but you are financing a purchase, not receiving free equipment. Always ask: “Who owns the system?” See our guide to solar scams for more red flags.
Myth 7: Solar Is Only for Wealthy Homeowners
Fact: $0-down solar loans have made solar accessible to homeowners across income levels. If your monthly solar payment is less than your current electric bill – which it often is – you save money from day one regardless of income. The 30% federal tax credit is available to anyone with federal tax liability, and financing options exist for a wide range of credit profiles.
Solar is increasingly a financial decision, not a luxury purchase. See our financing options guide.
Myth 8: Solar Takes Too Long to Pay for Itself
Fact: Typical payback periods are 6–10 years (5–8 years in South Carolina). After payback, you receive free electricity for 15–20+ additional years. That is 15–20 years of pure savings with no ongoing cost.
For context: a new kitchen or bathroom renovation never “pays for itself.” Solar is one of the few home improvements that actually generates a positive financial return. See our ROI and payback guide.
Myth 9: Solar Panels Are Not Efficient Enough
Fact: Modern residential panels achieve 19–23% efficiency, which is more than sufficient to power an entire home with 15–30 panels. The question is not whether panels are “efficient enough” in the abstract – it is whether the energy they produce offsets your electricity cost, which it does for the vast majority of homeowners.
Efficiency improvements continue, but current technology already delivers strong financial returns. Waiting for “better panels” means paying full utility rates every month while you wait. See our equipment guide.
Myth 10: You Cannot Go Solar If Your Roof Is Old
Fact: You can install solar on an older roof, but if your roof needs replacement within the next 5–10 years, it is usually smarter to replace the roof first (or simultaneously). Removing and reinstalling panels for a future roof replacement adds cost and complexity.
Gold Path Solar’s site survey evaluates your roof condition and will advise you honestly if a roof replacement should come first. In many cases, solar and roof replacement can be coordinated for maximum efficiency. See our solar and roof replacement guide.
Myth 11: Solar Panels Are Ugly
Fact: Modern all-black monocrystalline panels have a sleek, low-profile appearance that blends well with most roof styles. Solar panel aesthetics have improved dramatically – they no longer look like the bulky, silver-framed panels of decades past. Many homeowners and real estate professionals find that a clean solar installation actually enhances a home’s curb appeal.
Myth 12: Solar Panels Are Toxic or Bad for the Environment
Fact: Solar panels are made primarily of silicon (sand), glass, aluminum, and copper – common, non-toxic materials. They contain no hazardous substances during normal operation. A solar panel’s energy payback period (the time for it to generate as much energy as was used to manufacture it) is approximately 1–3 years – meaning it produces clean energy for 22–27+ years beyond its manufacturing footprint.
End-of-life panel recycling is a growing industry. Most panel materials (glass, aluminum, silicon) are recyclable. Responsible manufacturers and installers support recycling programs to keep panels out of landfills.

Myth 13: Solar Does Not Work During Power Outages
Partially true – but solvable. Standard grid-tied solar systems shut down during outages for safety reasons (to protect utility workers). However, adding a battery storage system allows your panels and battery to power your home independently during outages.
If backup power is important to you, a solar + battery system provides both savings and energy security. See our solar battery guide.
Myth 14: You Should Wait for Better Technology
Fact: Solar technology is mature and delivers excellent returns today. Waiting for “better panels” means paying full utility rates – which are rising 3–5% per year – every month you delay. The tax credit may also decrease in the future. Every year you wait costs you a year of savings and exposes you to policy risk.
Solar panel efficiency has improved incrementally over the past decade, but the financial case for solar is already overwhelmingly positive. Waiting for marginal efficiency gains while paying thousands per year in utility costs is a losing strategy.
Myth 15: All Solar Companies Are the Same
Fact: The difference between a good solar company and a bad one can cost you thousands of dollars and years of frustration. Key differences include:
- Pricing transparency: Some companies hide $4,000–$7,000 in dealer fees inside your loan. Others (like Gold Path Solar) offer zero-closing-cost financing.
- Installation quality: In-house crews vs. subcontractors. The difference directly affects system performance, roof integrity, and your warranty coverage.
- Customer experience: A dedicated Solar Advocate who knows your project vs. a call center that makes you repeat your situation every time.
- Equipment quality: Tier-1 panels and 25-year microinverters vs. budget equipment with shorter warranties.
- Company model: Referral-driven growth (aligned with customer satisfaction) vs. lead-purchased, high-pressure sales (aligned with closing deals).

Frequently Asked Questions
What is the biggest misconception about solar?
That solar does not make financial sense. For the vast majority of qualifying homeowners, solar delivers a 10–15% annual return on investment with significantly less risk than the stock market. The financial case has never been stronger.
Is solar energy really reliable?
Yes. Solar panels are solid-state devices with no moving parts, backed by 25-year warranties. They have been deployed on millions of homes worldwide with proven performance data spanning decades. The technology is mature, reliable, and well-understood.
Will solar panels still be worth it in 10 years?
Almost certainly, but the current incentive package (30% federal ITC, state credits, strong net metering) may not last. Going solar today locks in the best available incentives and starts your savings clock immediately. Every year of delay is a year of savings lost.
Are there hidden costs with solar?
With a reputable installer, no. Hidden costs come from dishonest companies that bury dealer fees in financing, use cheap equipment that fails early, or leave you without support after installation. Choosing the right company eliminates hidden costs entirely.
