Ask for written assumptions

Key takeaway: Use this article to prepare better questions. A solar design, price, programme outcome or savings estimate must be confirmed for the individual property in a current written proposal.

Factory rooftop solar planning must combine energy data, structural assessment, electrical design, safety planning and production schedules.

A factory roof can provide useful solar space, but the project must be planned around access, loading, shutdown windows and long-term roof maintenance.

Start with the Factory Load Profile

Collect electricity bills, maximum demand, production hours and planned expansion. Separate steady daytime loads from intermittent machinery so the system is sized around actual operations.

Roof and Safety Questions

Roof age, material and structural capacity
Safe access and fall-protection plan
Cable routes and inverter locations
Fire, maintenance and emergency access
Coordination with roof replacement or refurbishment

Plan Installation Around Operations

A professional contractor should explain the installation sequence, site safety, testing, commissioning and handover documents. Production interruptions and access restrictions should be included in the project plan.

Frequently Asked Questions

Does every factory roof suit solar?

No. Roof structure, condition, shading, electrical connection and safety access all need assessment.

Can solar be installed without stopping production?

The answer depends on the electrical design and site conditions. The contractor should plan safe isolation and testing windows.
