Solar Design Services in Colorado

Proposal design for the sales stage, permit plan sets for Colorado authorities, 3D pre-design and shade studies, detailed engineering for rooftop and ground mount, civil and structural engineering with STAAD Pro verification, and yield and technical reports. Most Colorado installers start with one service and expand once turnaround and quality are proven.

Yes, and it is the substance of the work rather than a claim. Colorado has no single statewide building code, so adoption and enforcement sit with local jurisdictions. The state has moved to require automated permit processing for solar in larger jurisdictions, which has made parts of Colorado among the faster markets while smaller mountain jurisdictions continue with conventional review.

Xcel Energy, Black Hills Energy, Colorado Springs Utilities, Tri-State and member co-operatives, Fort Collins Utilities. Each expects its own diagram format and documentation, and export rules differ between them, which changes both the sizing case and what the drawings must show.

Colorado has a mature Front Range residential market, strong municipal utility participation, and a mountain resort segment with unusual design demands. The state requirement for automated permit processing in larger jurisdictions has made Front Range residential permitting notably faster, shifting competitive advantage toward design correctness rather than turnaround. The mountain and western slope markets remain conventional review, with high snow loads and design overlays that make them a specialist rather than volume proposition.

Yes. Commercial and industrial work brings structural calculations, equipment coordination and interconnection complexity. Our largest documented project is an 11 MW DC rooftop installation on tin shed structures, which required structural verification across dozens of shed roofs alongside the electrical design.

A second engineer reviews every set against a jurisdiction specific checklist before it leaves us. The reviewer is not the person who drew it, because the fastest way to miss a setback error is to check your own work. Structural output is verified in STAAD Pro rather than assumed from a racking table.

You do. Work is covered by NDA and all intellectual property in the deliverables transfers to you. We do not reuse your drawings, your customer data or your templates for anyone else.

Yes. No retainer, no minimum volume, no onboarding fee. Most clients send one project, check the output, then scale.

Wind: moderate on the plains, but Front Range foothill jurisdictions including Boulder County experience severe downslope Chinook winds with design values well above the regional map. Snow: extremely elevation dependent. Roughly 30 psf on the Denver plains rising past 100 psf in mountain jurisdictions, sometimes over short horizontal distances. Seismic: low across most of Colorado. Also governing: colorado sits in the most hail-prone corridor in the country, which affects module selection and insurance, and altitude affects module temperature behaviour and voltage. These decide the racking selection and attachment schedule, so we verify them per site rather than applying a regional default.

Local code adoption rather than a statewide building code. State requirements for automated solar permit processing in larger jurisdictions. Elevation-dependent snow load provisions that vary sharply within short distances. Local wind provisions in Front Range foothill jurisdictions where downslope winds are severe. We work from these rather than a national template, because each can produce a review comment on an otherwise sound design.

Denver Community Planning and Development (City and County of Denver): consolidated city-county authority with high residential volume and electronic submittal. Pikes Peak Regional Building Department (Colorado Springs, El Paso County and surrounding municipalities): a genuinely regional building department serving multiple jurisdictions from one office, which is unusual and simplifies filing across the Colorado Springs area. Boulder County Community Planning and Permitting (Boulder County): downslope Chinook wind exposure means local wind design values well above what the regional map suggests, and this catches installers from outside the area. Jefferson County Building Safety (Jefferson County): foothill terrain where elevation changes snow load and wind exposure between neighbouring sites. Mountain resort jurisdictions (Summit, Eagle, Pitkin and other mountain counties): very high ground snow loads and design review overlays. Conventional plan review rather than automated processing.

In larger jurisdictions, substantially yes. The state has moved to require automated permit processing for qualifying residential solar, which has cut Front Range permitting timelines considerably. Smaller and mountain jurisdictions continue with conventional plan review. The consequence is that in the fast jurisdictions nothing catches a design error before inspection, so correctness matters more than it used to.

More than in any other state we work in. Ground snow loads run around 30 psf on the Denver plains and exceed 100 psf in mountain jurisdictions, and the transition can happen over a few miles of elevation gain. Racking and attachment schedules cannot be standardised statewide, which is why we verify each project against its actual site value rather than a regional default.
