Solar & Battery Design Tools for Philippines Design Systems, Calculate ROI & Find Installers

Design solar and battery systems across the Philippines using Photonik's professional design platform. The Philippines enjoys strong tropical sunshine year-round, making it one of Southeast Asia's most promising solar markets. With high electricity prices and frequent grid reliability issues, rooftop solar offers Filipino homeowners both significant cost savings and energy security.

Energy Usage

Residential energy usage in Philippines typically ranges from 15-30 kWh daily, with 7 kWh being common for a standard household. Energy consumption patterns vary widely in Philippines, but 7 kWh per day is a useful starting point for comparing solar system sizes and expected savings.

Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.

Typical energy usage per person per day in Philippines:

Low (Efficient)
~4 kWh
Medium (average)
~6 kWh
High (intensive)
~9+ kWh

Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.

Solar System Sizing

Based on 7 kWh daily usage, a 1.8kW system is a good starting point for Philippines — though many homeowners choose to install slightly more. Going larger within the 2.8kW to 3.7kW range typically improves long-term value, since solar panels produce well for 25 years or more.

Expect around 12.8 kWh daily from a 2.8 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

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. Including a 10 kWh battery typically raises annual self-sufficiency to around 99%, with grid reliance dropping to 1%.

Local incentives and rebates can significantly improve battery economics — check what's available in Philippines and use the Photonik design tool to factor them into your calculations.

Solar & Battery System Cost Philippines


Understanding Solar & Battery System Costs

For Philippines homeowners looking to reduce their electricity bills, a ₱157,639 solar installation can dramatically lower or even eliminate that ongoing monthly cost. The 6.4-year payback estimate is based on current electricity prices — if rates continue rising, as they have historically, your actual payback could be even faster.

For the most accurate pricing, use the full Photonik design tool — it accounts for your specific roof, local installer pricing, and available rebates in Philippines.
