Solar Calculation Information
Important information for sales and site survey
How the calculator works
The appliance calculator multiplies:
Quantity × Watts × Usage Hours
to estimate daily electricity consumption.
Solar generation is estimated using:
Solar kW × Peak Sun Hours × 80% Performance Ratio
The rooftop calculation uses the number of panels and the approximate area required per panel.
The final system size should be confirmed after a professional site survey, shadow analysis, roof measurement, electrical assessment and applicable DISCOM / government requirements.
