What to prepare before a rooftop solar assessment

01

Start with existing drawings

Collect the available architectural plans, structural drawings and records of previous roof alterations. Drawings help the responsible engineer understand the building type, dimensions, structural system and details such as roof drains, equipment and access.

02

Record the building condition

Record the roof structure, waterproofing and overall condition. Note the roof type and visible damage. Share clear photos of roof surfaces, parapets, penetrations, existing equipment and the surrounding environment. A structural specialist determines the assessment scope from the available information.

03

Gather electricity-use information

Collect recent electricity bills or utility statements, ideally covering a complete seasonal cycle. Include demand information and planned future loads where available. This helps the electrical team review the load profile and the proposed system arrangement.

04

Clarify project goals

Explain what you want the project to achieve, including generation, storage, charging or essential-load backup. Share preferences and constraints such as construction timing, available installation space, budget range and phasing requirements.

05

Prepare for a coordinated review

Identify the building owner, facility manager, responsible electrical and structural specialists, and decision makers. Confirm site access and the information available. Xuexiang coordinates communication and the equipment or specialist resources required for the agreed scope.

Review scope depends on the site and available records.

Clear information helps the responsible specialists identify the next review and document the project scope.

Information checklist

Start with the information you already have. The exact document requirements depend on the project.

Information Why it helps
Available drawings and records Understand the building, system and existing equipment.
Site photos and conditions Review the setting, access and installation constraints.
Electricity-use information Review energy demand and the proposed operating arrangement.
Planned load changes Consider future demand and project phasing.
Project goals and constraints Match the review to the intended outcome.
Contacts and responsibilities Coordinate access, information and the agreed scope.

Ask About Your Site

Share your requirements and the information available. We will coordinate the next review.
