What solar work covers
Solar projects in the Denver metro typically include rooftop photovoltaic modules, racking, inverters, optional battery storage, and related panel or service work. Roof structure, fire-access pathways, and utility interconnection all affect layout. A municipally licensed Denver general contractor coordinates the project and licensed specialty trades for the electrical work. Cost is project-specific and depends on array size, roof condition, and whether storage or a panel upgrade is included.
text
Fire pathways and historic roofs
Denver CPD PV drawing guidance follows IRC pathway rules: typically two 36-inch roof-edge-to-ridge paths on sloped dwellings, with ridge setbacks of 18 or 36 inches depending on how much of the roof the array covers. Landmark properties and historic districts need a Landmark Certificate of Appropriateness before panels go on the roof.
text
Permits and who coordinates the work
City and County of Denver Community Planning and Development requires an electrical permit for solar. Many single-family and duplex projects, including storage and related panel upgrades, can use SolarAPP+ and then upload the confirmation in e-permits as a quick permit. Commercial and multifamily arrays still go through electrical plan review, and sometimes structural review. Utility interconnection is a separate utility process. Colorado DORA regulates electrical licensing. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades for solar scopes.
text
What buyers should prepare
Roof photos and age, landmark status if known, whether storage is desired, and utility account information for interconnection.
FAQ
Common questions
Do rooftop solar arrays need a Denver permit?
Yes. CPD requires an electrical permit. Many houses use SolarAPP+ as a quick permit; landmarks need a Certificate of Appropriateness as well.
Who handles solar permits and licensing?
A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Colorado has no statewide general contractor license.
Is utility approval the same as the city permit?
No. CPD inspects the installation. Interconnection with the serving utility is a separate application.
Can I cover the whole roof with panels?
Not usually. IRC pathway and ridge-setback rules used in Denver CPD drawings keep clear routes for fire access.
What information helps define scope?
Roof photos, electric bills or usage, storage interest, landmark status, and city or county.
