A factory's ordinary weekday can make rooftop solar look well matched to demand. A holiday shutdown tells a different story: the roof may keep generating while production stops. The project model should include those periods, because the value of electricity depends partly on what the customer can do with it when it arrives.
The real calendar
Obtain a view of working days, seasonal closures and expected changes in production. A yearly consumption total can conceal these patterns. The objective is not perfect foresight, but a more representative account of the customer's operation than a model built around one busy week and repeated across the entire year without adjustment.
The unused output
Where generation exceeds on-site use, the treatment depends on the actual system and applicable arrangements. Confirm those details through qualified project and commercial review. The owner should not assume every unit receives the same value, particularly when the customer contract and the wider electricity arrangements treat self-consumption and other destinations differently in practice.
The communication interface
The asset operator needs notice of significant customer schedule changes. A new shift or extended closure can affect planning and reporting. Establishing that communication helps the parties explain variations in the project's result, rather than interpreting every change through equipment performance while overlooking the industrial activity that creates the demand behind the meter.
A project tied to a business
Rooftop solar serves a customer whose operation evolves. For investors, that connection deserves continuing attention after commissioning. A robust commercial model reflects the customer's working rhythm and a process for updating it, allowing the project to be assessed as a service integrated with a real enterprise rather than a fixed relationship between roof area and annual electricity production.
