When you need this permit
- All plans and documents must be submitted through the applicant's eTrakit account, in PDF format only
- Application must include the proposed PV system capacity in Watts and whether the system is stand-alone, grid-tied, or hybrid
- A copy of the C.O.R.E. utility Level 1 application form with the application ID number is required
- A separate valuation and cost breakdown is required for any additional work performed (e.g., electrical service change/upgrade, sub-panel installation, battery backup system)
- Roof-mounted panels: an engineer's signed, sealed, and dated letter evaluating the existing roof structure's dead-load capability and its ability to support the added PV weight is required, referencing the required wind and snow load for the site; if panels project above the roof ridge line, this must also be addressed in the engineer's evaluation; the engineer must stamp all associated structural plan pages
- Pole or ground-mounted panels: site plan showing panel location, dimensions to property lines, dimensions to other structures/easements, and an engineered footing design
- One-line wiring diagram required: system type (stand-alone/grid-tied/hybrid), conductor sizes/insulation/material, conduit sizes/type, overcurrent protective device ratings, existing/new panel amperage ratings, PV production meter rating, AC disconnect rating, and module series/parallel configuration
- Product listing sheets required for all equipment (modules, inverters, batteries, combiner boxes, disconnects, charge controllers, racking system), including module short-circuit current and open-circuit voltage ratings, inverter output circuit current rating and UL listing, method of grounding, and DC Arc-Fault Protection per NEC Article 690.11
- All Solar PV inspections (rough electrical, rough frame, final electrical, final building and electrical service) must be scheduled for the same day; the contractor must be on site with Town-stamped plans and the signed Solar PV Rooftop Installation Affidavit; inspector needs attic access; a solar rapid-shutdown test is performed at this time
- A separate Detach-Reattach Solar Photovoltaic Affidavit is required when removing/reinstalling an existing array (e.g., for a reroof)

Tips
- Parker publishes a genuinely flat solar fee — $500 residential / $1,000 commercial — rather than a valuation-based calculation, and an explicit review-time goal of 10-14 business days for simple systems, a level of transparency not every jurisdiction in this corpus provides.
- All Solar PV inspections (rough electrical, rough frame, final electrical, final building/electrical service) must be scheduled together for the same day — plan contractor availability accordingly.
- A C.O.R.E. utility Level 1 application with its ID number must be submitted alongside the Town permit application — don't submit to the Town before starting the utility interconnection process.
- Roof-mounted systems need a signed/sealed/dated engineer's letter addressing dead-load capacity AND the site's specific wind/snow load — a generic manufacturer spec sheet is not sufficient on its own.

If your project isn't listed, confirm with Town of Parker Building Division (Community Development Department) at 303-841-1970 before starting work.
The Town charges a flat $500.00 permit and plan review fee for residential solar PV systems, or $1,000.00 for commercial projects, plus applicable taxes — set per State requirements rather than calculated from project valuation.
The Town's stated goal is to review all simple solar permits in 10-14 business days, per the Town of Parker Solar Energy Systems page.
You'll need: Solar Photovoltaic System Application Checklist; Solar Photovoltaic Rooftop Installation Affidavit; C.O.R.E. Utility Level 1 Application (with Application ID). Depending on your project, Parker may also ask for: Sample Solar System Plan; Solar Thermal System Plan Application Checklist; Detach-Reattach Solar Photovoltaic Affidavit. See the required-documents checklist on this page for details on each.
