Energy Usage
To choose the right solar system in Iloilo, start by understanding your daily electricity consumption. Whilst typical Iloilo households consume 7 kWh daily, homes with good insulation and modern appliances often use far less energy.
Simple changes like sealing draughts, upgrading to LED lighting, and setting hot water timers often cost far less than extra solar panels and deliver immediate bill savings.
Typical energy usage per person per day in Iloilo:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 1.8kW solar system would typically cover your average daily electricity consumption. Optimal sizing ranges from 2.8kW to 3.7kW to accommodate daily and seasonal generation variations.
While December is the weakest month for solar in Iloilo, September more than makes up for it — and a battery can help bridge the gap between seasonal highs and lows.
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 Iloilo
Solar Battery Sizing
A solar-only system in Iloilo covers about 50% of your energy needs during daylight hours, but without a battery the 50% you use at night still comes from the grid. The jump from 50% to 99% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.
