Solar Design Pretoria
Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Pretoria. Whilst typical Pretoria households consume 15 kWh daily, homes with good insulation and modern appliances often use far less energy.
Lowering energy usage before solar installation—via improved insulation and efficient appliances—often reduces required system size and enhances financial returns.
Typical energy usage per person per day in Pretoria:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
To offset your average consumption, you'd need roughly 3.9kW of solar capacity. We recommend sizing between 5.9kW and 7.9kW for optimal results as solar output fluctuates daily and seasonally.
A 6.6 kW solar installation in Pretoria typically produces 29.3 kWh per day on average, with seasonal output ranging between 3.80 kWh/kW/day (June) and 4.87 kWh/kW/day (October).
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Pretoria
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Pretoria, depending on your consumption patterns, drawing 50% from the grid. With a 10 kWh battery added, energy independence increases to approximately 99% per year, whilst grid dependency falls to 1%.

Solar & Battery System Cost Pretoria
Understanding Solar & Battery System Costs
A 6.6 kW solar system in Pretoria is priced at approximately R106,088, whilst adding 10 kWh of battery storage increases the total investment to around R213,957. Solar systems typically achieve payback in around 5.8 years, whilst adding battery storage extends the payback period but provides greater energy independence.
The pricing breakdown includes equipment, installation labour, and applicable taxes. Use the sliders to adjust system size and battery capacity to see how pricing and payback change.
