Define the energy and resilience goal
Use available utility consumption and planned loads to state the design basis. Separate bill offset from battery backup because backup loads and controls require additional design decisions.

Quick answer
What should a Tualatin solar proposal include?
Require energy and load evidence, service and panel assessment, roof and shade findings, one-line design, named equipment, city and county permit duties, serving-utility interconnection, outage planning, commissioning and owner closeout records.
Document the existing electrical system
Record service and panel ratings, spaces, grounding, bonding, meter arrangement, major loads and prior alterations. Separate safety correction from capacity needed for the new connection.
Resolve roof and attachment conditions
Identify material, condition, penetrations, drainage, shade and attachment locations. Assign structural review, flashing and responsibility for future removal during reroofing.
Confirm Tualatin structural review
The city accepts building applications online and directs exterior work through planning before building review. Identify plan, correction and inspection responsibilities for the exact roof design.
Obtain Washington County electrical approval
Tualatin states that electrical permitting and review are contracted to Washington County. Include the county permit record required by the city solar process.
Confirm the serving utility
Permit approval does not equal utility interconnection. Verify the account, application, meter work, equipment-data and permission responsibilities for the serving utility.
Plan outage and commissioning
State shutdown timing and essential-load needs. Verify labels, grounding, protective functions, rapid shutdown, monitoring and operation against the approved design.
Deliver a complete owner file
Retain approved plans, city and county permits and finals, utility acceptance, serial data, photos, warranties, monitoring credentials and shutdown instructions.

Tualatin handles the city solar and structural path, while Washington County handles electrical permits and review.
