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.
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Some come from aggressive solar marketing that over-promises; some come from anti-solar talking points that are decades out of date; some come from well-meaning neighbors who remember something from a long time ago.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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
