ROI Calculator
Estimate your solar savings
Answer a few questions about your property and energy usage to see an indicative system size, annual production and potential payback. Every assumption is visible and adjustable.
INDICATIVE ESTIMATE · NOT A QUOTATION OR ENGINEERING DESIGN
This is an indicative estimate, not a quotation or engineering design. Final recommendations depend on a site assessment, load profile, tariffs, equipment selection and professional modelling. No savings or payback figures shown here are guaranteed.
Good questions
About the calculator
Straight answers to the questions we hear most. For anything specific to your property, an assessment gives you numbers rather than generalities.
How accurate is the calculator?
It is an indicative model using conservative South African assumptions: your tariff, location-based solar yield and typical system costs. It is designed to show whether solar deserves a proper look, not to replace engineering. A site assessment and load profile always precede a real proposal.
Why do you ask about my monthly bill instead of kWh?
Most people know their spend, not their consumption. We derive an estimated annual consumption from your bill and tariff, and you can adjust the tariff assumption if you know your exact rate.
Does the estimate include batteries?
If your objective includes backup or maximising solar usage, the model adds indicative battery capacity and its cost. Battery sizing in practice depends on which circuits you protect and how long outages last, which the assessment defines precisely.
