For South African businesses

Commercial solar project screening calculator

Turn six early-stage facts into a practical assessment route. The result tells you what to validate next without pretending a monthly bill can determine panels, inverter capacity or battery size.

Six screening inputs

Describe the project before discussing size

All fields are required. The result identifies a practical assessment route; it does not calculate system capacity, savings or approval.

A useful first answer is a route, not a guessed system size

A commercial electricity bill combines energy, demand, network and fixed charges. It does not reveal when the site uses power, whether a landlord can approve the work, or which distributor controls the connection.

Complete the six inputs to see which evidence and decisions should come next.

Why the tool does not estimate system size

Two businesses with the same bill can need very different systems. One may use most of its electricity while the sun is up; another may pay a large demand charge or run refrigeration overnight. Export limits, phase supply, roof area, shading, structural condition and future expansion can change the design again.

Use the screening result to commission the right work. A provider or appointed professional should still verify the load profile, site, tariff, connection, approvals, engineering and commercial model.
