Solar Panel Installation in Johnson City, Oregon
Johnson City is not like anywhere else we work. It is a city of about 540 people occupying seven hundredths of a square mile between Milwaukie and Gladstone — 278 housing units, almost all of them manufactured homes. It became a city in 1970 when residents of a trailer court that Delbert Johnson had started in 1959 voted 49 to 10 to incorporate, and it is now the most densely populated city in Oregon. Nearly every home in it is owner-occupied.
Solar on a manufactured home is a genuinely different engineering problem from solar on a stick-built house. Most companies quote it as though it is not, which is how people end up with a proposal that cannot be built.
The Roof Is the Whole Question
HUD-code manufactured homes are built light on purpose — they were designed to travel down a highway. Roof structures are typically shallower and more widely spaced than site-built framing, and the covering is often metal or a low-slope membrane rather than composition shingle over plywood. Three things follow from that.
- Attachment. You cannot lag into a rafter you have assumed is there. Fastening has to land on located, verified structure — and on a metal roof it may be clamped to the seam instead of penetrating it at all.
- Load. Added weight is checked against what the home was built to carry rather than against a rule of thumb. Sometimes the honest answer is a smaller array, or a different section of roof.
- Sequencing. Many of these roofs have been coated more than once. If yours is near the end of its life, it gets dealt with before an array goes on top of it.
None of that makes solar impossible on a manufactured home. It makes it work for somebody who checks instead of assuming.
Who Owns the Ground Matters As Much As Who Owns the Roof
In manufactured-home communities the home and the land underneath it are often owned separately. If you own the home but lease the space, an array is a permanent improvement to something you own, fixed to something you do not — so written permission from the park, and a clear understanding of what happens if the home is ever moved or sold, belong in the conversation before anyone draws a layout. Where you own both, it is a much simpler project.
We ask about this in the first phone call, because the answer changes what we recommend rather than just the paperwork.
Space, Service and Meters
At seven hundredths of a square mile there is no room here for the usual fallback of a ground mount in the yard. It is the roof or nothing, which puts a premium on getting the most out of a small, well-oriented area — higher-efficiency modules earn their price on a roof this size.
Electrical service is the other constraint. Older manufactured homes commonly run 100-amp service, sometimes fed from a pedestal meter set away from the home, which affects where the inverter and disconnect can live and occasionally means a service upgrade before anything can be interconnected. Alterations to a manufactured dwelling are permitted through the local building department; we confirm the requirements for your address and pull them.

Johnson City Solar FAQs
Can you actually put solar panels on a manufactured home?
Yes, when the structure supports it. Manufactured homes use lighter roof framing than site-built houses, so the array has to be attached to located, verified structure and the load checked against the home’s design. We survey the roof before quoting rather than after.
I own my home but lease the space — can I still install solar?
Often, with the park’s written permission. Because the array is fixed to a home that sits on land you do not own, we want that agreement and a plan for what happens if the home is ever sold or moved settled before design, not after installation.
Is there room for a ground-mounted array instead?
Not in Johnson City. This is the most densely populated city in Oregon and there is no spare ground, which makes module efficiency and roof layout matter more here than almost anywhere else in the metro.
Will 100-amp service handle a solar system?
Sometimes, depending on the system size and how the interconnection is made. Where it will not, a service or panel upgrade is quoted up front as part of the project rather than discovered on installation day.
