Solar Design Philippines
Energy Usage
The right solar system size for your Philippines property depends on how much electricity you use each day. The average household uses around 15 kWh per day, whilst energy efficient properties may use only half that.
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 Philippines:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 3.9kW of solar to match your average consumption. We recommend sizing between 5.9kW and 7.9kW for optimal results as solar output fluctuates daily and seasonally.
Expect around 30.2 kWh daily from a 6.6 kW system in Philippines, with production varying from 4.15 kWh/kW/day in December to 4.92 kWh/kW/day in September.
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 Philippines
Solar Battery Sizing
A 6.6 kW solar-only setup in Philippines delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. Installing a 10 kWh battery boosts your energy independence to around 99% per year, cutting grid dependency down to 1%.

Solar & Battery System Cost Philippines
Understanding Solar & Battery System Costs
A 6.6 kW solar system in Philippines is priced at approximately ₱309,354, whilst adding 10 kWh of battery storage increases the total investment to around ₱623,901. Payback periods for solar-only installations average approximately 8.0 years, whilst battery storage extends payback but significantly improves energy independence.
The breakdown covers equipment, installation, and taxes. Adjust the system size and battery sliders to see how different configurations affect your investment and payback timeline.
