Begin with the operating profile

Review operating hours, connected load, demand pattern, roof condition and expansion plans. These factors shape the engineering approach and whether the system should prioritise daytime offset, available roof area or a phased rollout.

Engineering should be visible

A professional EPC conversation covers structural checks, electrical single-line thinking, protection, cable routes, inverter locations, access and commissioning checks. Ask what is included before comparing only the headline price.

Measure the outcome responsibly

Production and savings depend on weather, shade, equipment, tariff and operating conditions. Use indicative estimates as planning inputs, then confirm the final design and commercial case through a site-specific proposal.

Before you decide

Ask for a site-specific assessment.

Confirm inclusions, safety and handover.

Compare complete proposals, not only price.
