Establish the energy and load basis
Collect available utility usage and identify planned electric loads. Distinguish bill-offset goals from battery backup or resilience because those choices change equipment, controls and commissioning.
Forest Grove solar crosses several distinct responsibilities. The city publishes a prescriptive solar checklist and structural building guidance, Washington County performs electrical permitting and inspections, and Forest Grove Light & Power publishes an interconnection checklist. The proposal should name each handoff before equipment is ordered.
Require usage and load evidence, service and panel assessment, roof and shade findings, an equipment schedule and one-line, city and county permit responsibilities, Light & Power interconnection, outage planning, commissioning and complete closeout records.
Collect available utility usage and identify planned electric loads. Distinguish bill-offset goals from battery backup or resilience because those choices change equipment, controls and commissioning.
Record service rating, panel ratings and spaces, grounding, bonding, meter arrangement, major loads and prior alterations. State whether correction or capacity work is included.
Document roof material, condition, penetrations, shade, drainage and attachment locations. Assign structural review, flashing and future removal responsibility if roof work will occur during the system life.
Forest Grove publishes a prescriptive solar permit checklist and states that Washington County handles electrical permits and inspections. List both paths and who answers corrections.
Forest Grove Light & Power publishes a solar interconnection checklist. Identify application, equipment-data, meter and acceptance steps separately from building and electrical approval.
Search the construction business through Oregon CCB and verify the electrical party through applicable records. Name who designs, permits, installs, commissions and responds to callbacks.
State shutdown timing and essential-load needs. Verify labels, grounding, protective functions, rapid shutdown, monitoring and operation against the approved design.
Retain approved plans, city and county permit finals, utility acceptance, equipment serials, photos, warranties, monitoring access and shutdown instructions.
Describe your project once and we help connect your request with relevant local contractors who serve your area. The request is free, there is no obligation to hire, and you decide whether anyone is right for the job.

| Review | Responsible question | Completion evidence |
|---|---|---|
| City building | Does the roof design meet submittal requirements? | Issued structural permit and inspection |
| County electrical | Is the electrical installation approved? | Electrical permit and final |
| Light & Power | Is interconnection complete? | Utility acceptance or permission |
| Roof | Are condition and attachments resolved? | Photos and approved detail |
| Service | Can the existing system accept the connection? | Ratings, load basis and one-line |
| Operation | Does the installed system match approvals? | Commissioning and monitoring record |
Separate assessment, design, building and electrical permits, interconnection, service work, modules, inverter, mounting, pathways, monitoring, shutdowns and closeout. Require disclosed assumptions for production or savings.
The city handles structural building review and directs electrical permits and inspections through Washington County; confirm the exact project with both paths.
No. Utility interconnection, city structural review and county electrical approval are separate responsibilities.
No. The decision follows existing equipment condition, ratings, loads and connection design.
Yes. Confirm condition, attachment design and future reroof responsibility before releasing roof-mounted equipment.
Search the legal construction business through Oregon CCB and verify the electrical business through applicable state records.
Treat production and savings as assumptions unless the contract documents the basis and a specific remedy.
Confirm installed equipment, labels, grounding, protective functions, shutdown, monitoring and operation against approvals.
Keep approved plans, all permit finals, utility acceptance, serial data, warranties, photos, monitoring and shutdown instructions.
Share usage, service, roof and project-goal evidence for proposals that include every approval handoff.
