The short answer
The technical questions for a townhome are the same as for any house. The ownership question is not. Before anything else, establish in writing whether you own the roof above your unit or the association does, because if the association owns it, you are not the one who decides.
What should you know first about solar for townhomes and row houses?
It limits HOA bans on your own roof, not on common property.
Attached roofs are long and thin, and neighboring units can shade them.
Fixed costs spread over fewer panels.
The panel serving your unit must be yours alone.

Who owns the roof?
Roof ownership is the deciding question for a townhome, and your declaration and bylaws answer it, not intuition.
In a fee-simple townhome you own the structure, roof included, and your position is close to a detached home. In a condominium-style arrangement the roof can be a common element, owned together and maintained by the association, even when the unit below is yours.
Get the relevant clause in writing before paying for a site assessment. Condos and shared roofs covers the variations.
What can an HOA require, and what can it not?
State solar access laws, where they exist, limit an association’s power to ban solar outright. California Civil Code §714 is one example.
Those laws do not give you the right to install on property you do not own. They limit unreasonable restrictions on your own roof; they do not turn common property into private property.
So establish ownership first, then check what your state’s law says about the restrictions the association applies. Solar access rights by state sets out where those laws exist.
What limits an attached roof?
An attached home’s roof has a shape problem and a neighbor problem.
A deep, narrow roof gives a long thin rectangle, and panel layouts waste more of it than of a square plane.
Attached and nearby units, sometimes taller at one end of a row, cast shade you cannot fix on your own property.
Conduit routes and attachment points must respect party walls.
Worth checking in the governing documents as well as with the installer.
Why does a small system cost more per watt?
A small system costs more per watt because permitting, the interconnection application, the crew visit and commissioning cost much the same for six panels as for twenty-six.
Spread across fewer panels, those fixed costs raise the price per watt. A townhome system is not overpriced for that reason; it is smaller, and small systems carry overhead less efficiently.
Keep that in mind before comparing your quote with a neighbor’s detached-home figure. Cost per watt shows how to compare.

What moves the price of solar for townhomes and row houses?
No single national figure describes solar for townhomes and row houses. These are the variables that separate two quotes for it.
| Factor | Effect on a solar for townhomes and row houses quote |
|---|---|
| System size | Smaller arrays carry fixed costs across fewer panels, raising cost per watt. |
| Roof geometry | Narrow planes waste layout space and can force a less efficient arrangement. |
| Shade | Neighboring units can justify panel-level electronics. |
| HOA requirements | Specified conduit routes, screening or particular finishes add cost. |
| Electrical access | Where the service panel sits relative to the roof can mean a long conduit run. |

We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
