GoSun is promoting a solar carport that can be assembled in a day without concrete footers or permits, potentially allowing homeowners a way to generate electricity while sheltering their vehicles.

That being said, do local permits and physical reality line up with GoSun's claims?

Here's what to know

The GoSun Solar Carport combines a 4-kilowatt solar array with an approximately 195-square-foot structure, according to a Reddit discussion detailing the product information. Buyers can choose a basic solar structure, a grid-tied package, or a battery-equipped configuration.

The kit allegedly arrives in a single crate and can be assembled with basic hand tools by a team of two or three. Engineered base plates secure the structure to an existing surface, avoiding the need for concrete footers in many applications, the company says.

The permit claim is based on the carport's footprint falling below a common 200-square-foot threshold for accessory structures. Still, GoSun tells buyers to confirm the requirements for their property, since size alone does not make every installation exempt.

Going solar is one of the best ways to save money on home energy, and for those ready for a rooftop setup, solar leases in particular can deliver hundreds of dollars in monthly savings without upfront costs.

More background

GoSun lists powering electric tractors, utility vehicles, e-bikes, tools, pumps, and homes as potential carport uses. The structure can also shelter equipment or serve as a backyard pergola or outdoor workspace while generating electricity overhead.

The company estimates that the 4-kilowatt array can generate enough energy on a sunny day for about 25 to 75 miles of driving. Actual production varies with installation quality, inverter choice, weather, panel positioning, shade, time of year, and location.

One commenter pushed back on the claims, saying, "The bigger concerns is their comments about no permit and no footers. My town for one requires a permit." They added, "More importantly without footers it will fly away in a wind."

Another commenter noted that, "Normally under 200 sq/ft structures = no permit, but as soon as you add electricity it changes everything."

The comments mixed curiosity with caution. The idea of a solar carport was genuinely intriguing, but the company's claims made some skeptical.

What can be done?

Before ordering, buyers should follow GoSun's instructions to check local requirements and choose anchoring suited to their property.

GoSun lists earth anchors and ground screws as options, along with anchors for asphalt or concrete and epoxy-set anchors. Avoiding concrete footers does not eliminate the need for site-specific work to secure the carport for a windy day.

GoSun also notes that the location and selected configuration determine the final snow and wind ratings. While its powder-coated steel structure and 10-degree roof are designed for outdoor exposure, those features do not remove the need to check engineering requirements for a particular installation.

For homeowners comparing clean energy options, EasyHome can also help them explore backup battery storage alongside solar. Pairing solar with a properly configured battery allows homeowners to maximize savings and power their home with solar when the grid goes down.

GoSun is accepting fully refundable reservations for its first production run, and actual shipping is scheduled for 2027, meaning buyers are placing a preorder rather than purchasing a kit available for immediate delivery.
