The question comes up more than people expect: can a manufactured home go solar?
The short answer is yes — but with more homework required than a standard site-built home. The complications are real, and most installers either don’t know them or don’t bother mentioning them until they’re already measuring your roof.
Here’s what’s actually different and what to look out for.
The Roof Structure Problem
Manufactured homes — built to HUD code rather than local building codes — use roof framing systems that are often lighter than site-built construction. Standard solar racking systems use lag bolts that screw into roof rafters. On a site-built home with 2×6 rafters on 24-inch centers, this is straightforward. On a manufactured home with lighter truss systems at non-standard spacing, lag bolt installation requires more care and sometimes different hardware.
This doesn’t make solar impossible. It means the installer needs to locate structural members accurately and use appropriate fasteners. A roofer experienced only with site-built homes may not know how to find the structural members on a manufactured roof. Ask specifically whether the installer has done manufactured home installations before.
Some manufactured home owners address this by switching to a ground-mounted system on their property instead of rooftop, eliminating the roof penetration question entirely. If you own the land and have usable yard space, this is often the cleaner solution. I’ll cover ground mounts fully in a dedicated post — but for manufactured homeowners in particular, it’s worth knowing that option exists.
Ownership and Financing Considerations
Solar loans and some solar leases require the solar system to be attached to real property that the borrower owns. Manufactured homes sitting on leased land — a common arrangement in manufactured home communities — can complicate this. If you don’t own the land, you may not qualify for the same financing products as site-built homeowners.
Cash purchases sidestep this. The 30% federal tax credit applies to manufactured home solar installations the same as any other residential property — there’s no site-built-only restriction in the IRA. If you own your manufactured home (even on leased land) and have sufficient tax liability, you can claim the credit.
Manufactured homes titled as personal property rather than real property also affect whether solar increases assessed value — and whether the property tax exemption that most states offer on solar applies to you. Check your state’s specific rules. In most states, the property tax exemption follows the real property classification, so personal property titled manufactured homes may not benefit from it.
The Utility Interconnection Question
Utility interconnection for manufactured homes works the same as site-built homes — the utility doesn’t care about your home’s construction type, only about the electrical system meeting interconnection standards. If your manufactured home’s electrical panel is up to code and can accept a solar interconnection, there’s no manufactured-home-specific barrier on the utility side.
Older manufactured homes with 100-amp service panels (common in units from the 1980s and 1990s) may need a panel upgrade before a solar system can be safely connected. Panel upgrades typically run $1,500–$3,500 and are a separate cost from the solar system itself.
What Size System Makes Sense
Manufactured homes typically have lower electricity consumption than comparable site-built homes — smaller square footage, often in climates where heating and cooling loads are moderate. A 3–6kW system covers the consumption of most manufactured homes, compared to the 8–12kW systems common in site-built suburban homes.
Smaller systems cost less in absolute terms — a 4kW system might run $12,000–$16,000 gross before incentives — and the 30% ITC brings that to $8,400–$11,200. The payback math at these sizes is often very similar to larger site-built installations because the lower consumption means the system can cover a high percentage of total usage.
Finding the Right Installer
The honest challenge here: not every solar installer knows how to do manufactured home installations correctly. Ask directly: “Have you installed solar on manufactured homes before? How many?” If they haven’t, they may underestimate the structural considerations or use racking hardware that doesn’t suit the roof framing.
Manufactured home owner forums and local manufactured housing associations can sometimes provide referrals to installers with specific experience. The extra homework is worth it — an installer who’s done this before will produce a safer, more durable installation than one who’s treating your home like a standard stick-built job.
Solar is feasible for manufactured homes. It just requires finding the right installer and understanding that a few extra complications are part of the process.
