Thinking about installing rooftop solar but unsure how much capacity you need, how much you’ll save, or whether your roof is suitable?
Our Solar Savings Calculator removes the guesswork by analysing your actual electricity consumption. Instead of generic assumptions, it uses your last three months of EB data to give you a realistic picture of your solar requirements, expected savings, and environmental impact.
Whether you’re a homeowner, business owner, or industrial facility manager, this tool helps you make an informed decision before moving forward.
With clear calculations and transparent estimates, you’ll know exactly what to expect—no exaggerated promises, no confusing numbers.
Check recommended system size, roof space, savings, and ROI instantly.

Most solar calculators online rely on averages and standard assumptions. While that may give a rough idea, it doesn’t reflect your real power usage.
Our calculator works differently.
By using your actual EB data from the last three months, it provides a far more accurate estimate of your solar needs. This helps avoid common problems like installing an oversized system or ending up with insufficient capacity.
Simple inputs lead to meaningful, practical outputs—so you can plan your solar investment with confidence.
Your Solar Estimate in Five Simple Steps
All results are displayed immediately after submitting your details.
We’ve successfully delivered solar installations for independent homes, schools, commercial buildings, and industrial facilities each designed for performance, safety, and long-term savings.
Our projects include:
Every system is custom-designed based on site conditions, energy usage, and future requirements.
The last three months of electricity usage help us calculate a realistic average while accounting for recent seasonal changes. This gives a more accurate estimate of your solar system size and potential savings compared to long-term assumptions.
Yes. You can enter either your electricity units or your bill amount. Our calculator automatically converts the values to generate accurate results, making it easy even if you don’t have unit details handy.
The savings displayed are estimates based on your consumption and current electricity tariffs. Actual savings may vary slightly depending on roof orientation, sunlight exposure, system performance, and future tariff changes.
Roof space gives an initial idea of whether solar can fit your requirements. Final feasibility is confirmed during a free site assessment, where we check structure, shading, and installation possibilities
You’ll instantly receive your solar report with system size, roof space, and savings estimates. If you’d like, our team can then assist with site inspection, detailed pricing, subsidy guidance, and complete installation planning.
Empowering a sustainable future with top-notch solar solutions from consultation, site visit, excellent plan, exceptional installation and maintenance support, helping you save on energy costs while welcoming green energy.
