Estimate What Solar Could Generate at Your Property
Use the Mr Solar PV Calculator to create an initial estimate based on your location and proposed solar array. It is a useful starting point before we assess the roof, shading, electricity use and battery requirements in detail.
Three simple steps to an initial estimate.
The result helps you understand possible annual generation. Mr Solar then turns that estimate into a property-specific solar and battery design.
Enter your location
Your postcode or property location helps the calculator use the relevant regional solar resource.
Describe the proposed system
Select the assessment type and provide the available roof or system information requested by the calculator.
Review the estimate
Use the result as a guide, then ask Mr Solar to check the roof, electrical installation, consumption and tariff strategy.
Mr Solar PV Calculator
Complete the calculator below. For the most accurate proposal, have a recent electricity bill or your annual consumption in kWh available.
Generation is not the same as bill savings.
The calculator estimates how much electricity a solar array may generate. Your financial result also depends on how much of that electricity you use directly, how much can be stored and how much is exported.
- Daytime electricity used directly in the home
- Surplus solar stored for evening and overnight use
- Battery usable capacity and discharge power
- Electricity import and export tariff rates
- EV charging, heat pumps and electric hot water
- Seasonal differences between summer and winter
A complete property assessment.
We compare the estimate with your actual consumption and design a system around the way the property uses electricity—not around a standard panel package.
- Roof condition, direction, pitch and shading
- Suitable 400–500W modern panel options
- Inverter size and maximum power delivery
- Battery capacity related to evening usage
- DNO application and export limitations
- Monitoring, certification and aftercare
