Buying a home is stressful, and finding out that one of the supposed money-saving features advertised on the listing doesn't function can create problems.
One prospective buyer found themselves in this situation. The house they were purchasing had an old solar system that was out of service, and the roof was in bad shape.
What happened?
In a post on Reddit, they wrote, "I am in contract to buying a house that has an 18-year-old solar system that doesn't work."
The grid-tied inverter had failed, two solar panels were damaged, and the roof needed to be replaced.
The setup was a 4-kilowatt system, so the buyer weighed two options: Ask the seller to focus on getting a new roof and remove the solar panels, or replace the roof and repair and reinstall the system.
Solar panels can reduce electricity bills for years, but once a system approaches two decades of use and sits on a roof near the end of its lifespan, repairs can become complicated.
Commenters said installing a new system may provide a better return on investment. "From what I see in that photo, the roof does indeed need to be replaced," one user wrote. "And an 18-year-old, non-working solar system? I'd have it pulled out completely and scrapped."
Why does it matter?

Timing is everything for buyers. If a roof needs to be replaced, reinstalling old panels may not be worth it. At the same time, getting rid of solar could mean losing out on future utility savings if the setup could be upgraded.
A broken inverter also means the system is not producing the electricity savings that usually come with rooftop panels. That makes inspections and negotiations especially important since lower energy bills were not a given.
What can I do?
The most practical next step was to get two independent opinions: one from a roofer on how much life the roof had left and another from a solar professional on whether the system was worth saving.
Buyers can use those findings to ask sellers for credits, repairs, or a lower purchase price rather than making a decision based on guesswork.
