Solar Myths, Debunked
Myth Busting

Solar myths, honestly debunked

Twelve of the most common solar myths in circulation, answered straight. If a salesperson or a forum post pushed one of these on you, here is the reality.

How to read this page

We hear these myths every week. Some come from aggressive solar marketing that over-promises; some come from anti-solar talking points that are decades out of date; some come from well-meaning neighbors who remember something from a long time ago. The common thread: none of them survive a close look.

Myth 1: "Solar does not work on cloudy days"

Reality: Panels produce less on cloudy days, but they still produce. A thin overcast might give you half your sunny-day output; heavy storm clouds might give you ten percent. Your system is sized for your full-year production, so a cloudy stretch in March is balanced by a sunny stretch in June.

Myth 2: "Solar gives you a zero electric bill"

Reality: You will still have a utility connection charge for staying on the grid. A well-designed system zeros out most of the electricity portion, not the whole bill. Any company promising a literal zero bill is either lying or going to under-size the contract so it works on paper but not in practice.

Myth 3: "Solar destroys your roof"

Reality: Professional installs use flashed, sealed penetrations that last longer than most roofs. Most roof problems attributed to solar are actually caused by bad installers cutting corners. A good installer protects the roof deck and leaves penetrations that outlast the surrounding shingles.

Myth 4: "You have to stay in your home forever"

Reality: Owned solar transfers automatically with the home and typically supports a higher sale price. Leased and PPA solar transfers to the buyer through the title company at closing. Neither path locks you in.

Myth 5: "Solar only works on south-facing roofs"

Reality: South is best. East and west work well, just at slightly lower per-panel output. Most homes have multiple exposures, and design works around what is actually there. North-only is the exception where solar usually does not pencil out.

Myth 6: "Free solar panels are real"

Reality: No. What the ad describes is a zero-down Solar Lease or PPA: no up-front cost, monthly electricity payment below your utility rate, financing partner claims owner-side incentives. A fair product, a misleading label.

Myth 7: "Panels need constant maintenance"

Reality: Panels have no moving parts. Rain does most of the cleaning. Inverters may need replacement once during the system life, depending on type. On our Solar Lease and PPA, all maintenance is included for the full term.

Myth 8: "Solar hurts home value"

Reality: Owned solar typically adds to appraised value and homes with solar often sell faster. Leased and PPA solar with clean contracts is neutral-to-positive. The "hurts value" story comes from a small number of poorly written legacy contracts, not from solar in general.

Myth 9: "The government buys your panels"

Reality: No federal or state program buys residential solar panels from homeowners. If a salesperson pitches you on "the government paying for your system," they are describing something else, usually a zero-down lease.

Myth 10: "You need a battery"

Reality: No. Net metering (credits on your utility account for surplus production) is what makes solar work for most homeowners, and it does not require a battery. Batteries add outage backup and time-of-use arbitrage, but they are optional and not always worth the cost. We will give you a straight answer on batteries based on your specific situation.

Myth 11: "Panels take more energy to make than they produce"

Reality: Not even close. Modern residential panels produce the energy used to manufacture them within one to three years. Then they produce clean electricity for decades more. This has been studied extensively and is not in serious dispute.

Myth 12: "Hail destroys solar panels"

Reality: Residential panels are tested to survive significant hail impacts. They are usually more hail-resistant than your roof. Extreme hail can damage panels, just as it damages roofs and cars; homeowners insurance typically covers panels under the same policy as the house.

Quick Answers

The one-line versions

Short answers for the ones we get asked the most.

Do solar panels work on cloudy days?
Yes, at reduced output. A cloudy day might produce anywhere from ten to fifty percent of a sunny day depending on the cloud type. Your system is sized for full-year production, not any single day. Virginia and Maryland both get enough annual sun to make solar work.
Will solar give me a zero electric bill?
No. No honest company promises a zero bill. You will still have a small connection charge with Dominion, BGE, Pepco, Potomac Edison, or Delmarva for staying on the grid. A well-designed system zeroes out most of the electricity portion, not the whole bill.
Will solar panels damage my roof?
Professional installs use flashed, sealed penetrations that typically last longer than the roof itself. Most roof problems after solar come from bad installers, not from solar. A good installer leaves your roof in better shape around the array than it was before.
Do I have to stay in my home forever to benefit from solar?
No. Owned systems transfer automatically with the home and typically support a higher sale price. Solar Leases and PPAs transfer to qualifying buyers through the title company at closing. We support you through either transfer path.
Does solar only work on south-facing roofs?
South is best. East and west work well, just at slightly lower total production per panel. North-only roofs usually do not pencil out. Most homes have multiple exposures, and we design around what is actually available.
Are free solar panels real?
No. What those ads describe is a zero-down Solar Lease or PPA. You pay nothing at install, but you still pay for electricity, usually at a rate below your utility. Nothing is free. The product can still be a fair deal when the contract is clean.
Do solar panels need constant maintenance?
No. Panels have no moving parts. Rain handles most cleaning for typical residential arrays. Inverters may need replacement once over the system life, depending on type. On a Solar Lease or PPA, maintenance is included for the full term.
Will solar hurt my home value?
Generally the opposite. Owned solar typically adds to appraised value and homes with solar often sell faster at a premium. Leased and PPA solar is neutral-to-positive when the contract is well-structured and transparent.
Does the government buy my panels?
No. There is no government program that buys solar panels from homeowners. If someone tells you Uncle Sam will pay for your system, they are using marketing language for something else, usually a zero-down lease or PPA.
Do I need a battery for solar to work?
No. Net metering is the main mechanism that makes solar work, and it does not require a battery. Batteries add backup during outages and can help with time-of-use rate arbitrage, but they are optional, not required. Get a straight answer on whether a battery is worth it for your situation before adding one.
Do solar panels cost more energy to make than they produce?
No, and not even close. Modern residential panels produce the energy used to manufacture them within roughly one to three years, then continue producing clean energy for decades. This has been extensively studied and is not a serious debate in energy research.
Does hail destroy solar panels?
Residential solar panels are tested and rated for significant hail impacts as part of standard manufacturer certification. They are more hail-resistant than most residential roofs. Extreme hail events can damage panels, just as they can damage roofs, siding, and vehicles. Homeowners insurance typically covers panels under the same policy as the house.
