After a gutter worker spotted a damaged solar panel, a homeowner was told they would need to replace a 21-panel rooftop array.
The baffled homeowner went to Reddit for advice.
The homeowner reported in Reddit’s r/solarenergy community that they contacted the solar company and were told they couldn’t replace just one panel.
The company’s proposal was a new rooftop array. “They’d have to replace all of them as those panels were no longer available,” the original poster wrote. “Is this really a thing?”
Commenters were skeptical of that assessment.
Residential solar can help lower electricity bills and provide energy independence. Some households may also save hundreds of dollars per month through $0 upfront solar leases. EasyHome offers a free explorer tool to estimate potential savings and connect homeowners with vetted local installers.
Whether the panels used series or parallel wiring would determine which specification a replacement needed to match, commenters said.
“All you need is a panel with either same amps or volts,” one said. “You want amps if they are wired in parallel or volts if they are wired in series.”
With energy prices through the roof, there’s never been a better time to go solar — and EasyHome can help you find the best prices from the best installers in your area.
EasyHome takes the guesswork and headaches out of energy upgrades by showing you estimated savings from a network of vetted local partners. To get started, just enter your ZIP and share a few details about your home — seeing your estimate is really that easy.
Another added, “As long as the specs are equal, you could have 20 different brands on your roof.”
For homeowners considering adding storage to their setup, EasyHome also offers options for exploring battery storage quotes. Pairing solar with an appropriately configured battery can allow you to use electricity when it costs less and provide backup power during outages.
