A $14,000 estimate dampened one homeowner's plan to turn an old carport into a low-cost solar setup.
Here's what to know
On Reddit's r/solarDIY, the homeowner asked whether the short structure could support a 5- to 6-kilowatt array without spending nearly that much.
Trying to figure out whether the project could be done more cheaply, the homeowner said, "This project would not be worth that much to me."
The OP said it's a "janky old carport" and its hollow steel tube posts were set in concrete.
They then added: "Well, AI can be a little too by-the-book sometimes. Can it be done?"
One user warned, "A good wind will pull screws right out and send the panels sailing." Another estimated that "5kw is over 600 lbs, not even including mounting hardware."
Project costs can climb quickly when installers must account for load-bearing capacity, wind uplift, mounting rails, foundations, and code compliance—especially on older carports, pergolas, or patio covers never designed for solar.
Used panels or discounted equipment listed online can make solar look inexpensive at first glance, but the supporting structure is often the more expensive part.

A bargain panel deal does not automatically mean a cheap installation. A solar setup that fails in high wind or overloads an existing structure can create repair costs, safety issues, and insurance headaches that wipe out any hoped-for savings.
What can be done?
A qualified installer or engineer can determine whether an existing carport can be reinforced or whether a purpose-built pergola or new solar canopy would provide a better return.
With EnergySage's help, the average person can save up to $10,000 on solar purchases and installations. And EnergySage's solar map shows the average cost of a home solar panel system on a state-by-state level, along with details on solar panel incentives for each state, which together can help readers get the best price for rooftop solar panels and access available incentives.
Adding battery storage to a solar setup is also one of the best ways to protect your home during outages, save money on energy, and go off-grid.

One user said, "Sounds like a tear down and rebuild to be able to safely support solar panels."

Each of these stories highlights a different part of the same issue: solar can seem affordable at first, but hidden fees, incentives, or utility bills can change the equation. They also help explain why a steep quote on an aging structure is only one piece of the decision.
• One homeowner nearly signed off before dodging $8,000 in hidden fees from a solar installer.
• On Reddit, the federal credit could still mean up to $9,000 off solar.
• One homeowner used grants and incentives to turn brand-new solar panels into yearly savings.
