Energy Usage
Your daily energy consumption determines the optimal solar system size for your home in Central Visayas. If your usage is above 7 kWh per day, switching to efficient appliances, smart hot water, or a pool pump timer can bring you closer to efficient-home levels.
Reducing your energy consumption before installing solar can lower your system size requirements and improve returns. Consider upgrading insulation and switching to energy efficient appliances first.
Typical energy usage per person per day in Central Visayas:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A solar system sized at approximately 1.8kW would cover your typical daily energy needs. Systems sized between 2.8kW and 3.7kW perform best, accounting for natural fluctuations in solar production.
Production peaks in September and dips in December, but across the year a 2.8 kW system in Central Visayas generates approximately 4,700 kWh in total.
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 Central Visayas
Solar Battery Sizing
At around 50% self-sufficiency without a battery, you're still buying 50% of your electricity from the grid — mostly in the evenings and overnight when solar isn't generating. A 10 kWh battery makes the most difference in winter when daylight hours are shorter — helping maintain closer to 99% self-sufficiency year-round rather than just in summer.
The best way to see whether a battery makes financial sense for your Central Visayas home is to model it with your actual usage — try the full Photonik design tool for a personalised estimate.

Solar & Battery System Cost Central Visayas
Understanding Solar & Battery System Costs
A 2.8 kW solar system in Central Visayas is priced at approximately ₱157,639, whilst adding 10 kWh of battery storage increases the total investment to around ₱486,817. While batteries extend the payback period beyond 6.4 years, they also protect against future electricity price rises and provide backup power during outages.
These are estimated costs — actual prices vary based on your roof type, equipment choice, and installer. We recommend getting at least three quotes to compare for your Central Visayas property.
