How this estimate works
Capacity = roof area ÷ 8 m² per kWp. Annual generation = capacity × 1,300 kWh per kWp. Gross savings = generation × your tariff. These are the existing calculator’s indicative assumptions, not a site-specific forecast.
This assumes all generated energy offsets electricity at the entered tariff. It excludes O&M, financing, taxes, degradation and export restrictions. Actual usable area, output and savings require an engineering and commercial assessment.

A LITTLE CLARITY
Good questions.
Clear answers.
01Is my rooftop suitable for solar?
Suitability depends on structural condition, usable area, shading and access. A site and structural assessment should be completed before the system size and design are finalised.
02How accurate is the solar savings calculator?
The calculator provides an indicative first-year estimate using area, generation and electricity tariff assumptions. Actual output and savings depend on site conditions, system design, consumption and applicable electricity arrangements. A detailed proposal needs an engineering assessment.
