Estimate system size, payback and ROI
Use your consumption and bill to establish a starting point. The result travels with your enquiry so the commercial team can check it against real site data.
Start with your business's actual energy use
A directional starting point based on Alumo's public business calculator. The final design still needs a site and load assessment.
Use electricity consumption for the recommendation. Pole fees and other fixed charges are excluded from the calculation, as they are on Alumo's calculator.
Your indicative starting point
Based on 12 500 kWh per month
This is a directional estimate, not a quote. Roof space, phase supply, operating hours, tariff structure and backup goals can change the design.

Model the commercial case
Adjust the system cost, expected bill offset and tariff increase. This is a transparent planning model, not a promise of performance.

SolarGuide estimate, not Alumo's proprietary calculation or a quote. It excludes finance costs, degradation, maintenance, tax, export credits and operating changes. A logged load profile and engineered proposal are required.
Need the inputs before the answer?
A business energy audit can establish the load profile and savings opportunities before a system is designed.
