Commercial solar installation in Detroit.
Commercial solar installation in Detroit for rooftop and parking structure PV systems, with permit planning before construction.
Start with the building, not the panels.
A commercial solar project has to fit the site, the roof, the electrical system, and the utility rules. We start with a solar feasibility study, then compare rooftop solar with solar carports where parking offers the stronger site.
One team carries design, permits, utility interconnection, construction, commissioning, and solar maintenance. We also compare direct ownership with solar financing and PPAs, and add battery storage only when it has a clear job.

What should a Detroit business plan before installing solar?
Commercial solar installation in Detroit starts with two choices: where the PV system will go and how the permit will be handled. We install rooftop and parking structure systems for commercial sites. The site choice changes the mounting location and project scope. Detroit does not allow construction on a structure without a permit. The city says review may take up to 20 business days for a commercial building. We plan the permit step before field work, so construction does not start before city approval.
Plan for Detroit permit review
Permit timing can change the project start date. Detroit says construction on a structure cannot begin without a permit from the Buildings Safety Engineering and Environmental Department. The city also says review may take up to 20 business days for a commercial building. Before setting a field schedule, confirm the permit type, the documents to submit, and who will file them. A schedule fails our start check if construction is set to begin before the permit is issued.
Permit start check
How is commercial solar installation permitted in Detroit?
- Confirm whether the rooftop or parking structure plan needs a Detroit building permit; the answer changes the approval path.
- Name the permit type before filing; the permit type changes which application and documents are prepared.
- Record who will file the permit; Detroit says a licensed contractor can apply for a commercial structure trade permit.
- Place permit approval before construction on the schedule; no structural construction starts before approval.

WHAT WE HANDLE
Everything under the solar door.

PROJECT PLANNING
What records should a Detroit solar PV project keep?
Installation guide decision
GUIDE
Record whether the project will follow the NREL commercial and industrial PV guide. The guide is voluntary, so the choice changes the project rules used by the team.
Project development scope
SCOPE
List whether project development is included. An included scope changes who prepares the project before installation.
Permit record
PERMIT
Keep the issued Detroit permit with the project file. The record shows whether structural construction may start.
System location record
SITE
Name rooftop or parking structure in the approved scope. The record fixes where the PV system will be mounted.
System fit choice
Which commercial solar installation fits a Detroit site?
Rooftop PV system
ROOF
Choose a rooftop system only when the solar equipment is planned for the building roof. That choice sets the mounting area and roof work in the scope.
Parking structure PV system
PARKING
Choose a parking structure system when the array belongs over or on the parking area. That choice moves the mounting scope away from the main roof.
Turnkey project
DELIVERY
Decide whether one project scope should cover development, permitting, and installation. That choice changes how many parties the buyer must manage.
Permit status
PASS/FAIL
Pass only when the required Detroit permit is issued before structural construction begins. A missing permit stops the field start.


BEFORE YOU BUY
How does Detroit exposure affect a solar PV plan?
- Record whether panels and mounting equipment will sit on a roof or parking structure; the location sets which outdoor area must be checked.
- Use Detroit's recorded annual snowfall of about 28 inches when defining the weather data for the exposed PV site.
- Use Detroit's recorded annual precipitation of about 35 inches when defining the weather data for the exposed PV site.
- Keep the weather data period with the project file; the supplied Detroit figures cover 1991 through 2020.
