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.

Commercial solar design should begin with the building’s load profile, operating hours, roof condition, electrical connection and business objectives.

A commercial proposal needs more than a residential package. It should explain how the system fits operations, safety requirements, maintenance and future expansion.

Why Commercial Solar Needs a Different Assessment

Factories, warehouses, retail sites and offices can have different load patterns, roof structures and operating schedules. The system should be designed around actual maximum demand and daytime consumption.
