Solar & Battery Pricing for Philippines Design, Cost & Payback Calculator
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.
Solar Planning & Design
To size your system, start with two questions: how much electricity you use, and how much roof space you have.
1. Energy usage
A typical Filipino household uses between 5–10 kWh of electricity per day (150–300 kWh/month), with air-conditioned homes in Metro Manila or Cebu often reaching 12–15 kWh daily. The Philippines has a tropical climate with consistently high temperatures year-round, so cooling is the dominant variable — a single window-type AC unit running 8 hours adds roughly 4–5 kWh/day. Refrigerators, electric fans, and lighting make up the baseline. Seasonal variation is modest, though the hot dry season (March–May) typically pushes consumption higher. We start with your daily energy usage because it determines the system size needed to meaningfully reduce your Meralco or local utility bill.

Representative flat export rate (feed-in tariff). What you earn per kWh of surplus solar exported to the grid. Your actual rate depends on your provider, plan, and time of day.
Estimated at 75% of the retail grid rate. A battery lets you store daytime solar and export during expensive peak hours, so each exported kWh is typically worth more than a flat feed-in tariff. Real returns depend on your time-of-use tariff and battery efficiency.
2. How many panels can fit on your roof?
Filipino homes predominantly use corrugated metal (GI sheet) roofing on pitched frames at 15–30°, which works well with rail-mounted solar clamps. Urban homes in subdivisions often have concrete tile or flat concrete roofs that allow standard flush-mount or tilt-frame installations. A typical single-storey home has 30–50 m² of usable roof area, fitting 6–12 panels (2–5 kW). Multi-storey townhouses may have only 15–25 m² of rooftop. Water tanks (elevated tipo), satellite dishes, and nearby structures casting shadows are common space reducers in dense residential areas.
Installations must comply with the Philippine Electrical Code (PEC) and use equipment listed with the DOE (Department of Energy). For net metering eligibility, the system must not exceed 100 kW and must be installed by a licensed electrical engineer or master electrician. The distribution utility (e.g., Meralco) inspects the installation and installs a bidirectional meter before activation. All inverters must have anti-islanding protection and meet relevant IEC standards.

System sizing Philippines
System Costs
The overall price of a solar and battery system depends on equipment quality, installation complexity, and any available rebates or incentives.
Estimated price
Solar prices in Philippines have come down significantly in recent years — a 2.8 kW system now costs around ₱157,639, making the economics more attractive than ever. Payback periods for solar-only installations average approximately 6.4 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.

Rebates & incentives
The Philippines does not offer a direct national cash subsidy for residential solar installations. The primary government support is the net metering programme (DOE Department Circular 2013-05-0009 and subsequent updates), which allows systems up to 100 kW to export excess generation for credits. Solar equipment imports benefit from duty-free treatment and VAT exemptions under the Renewable Energy Act of 2008 (RA 9513), which also provides a 7-year income tax holiday for RE developers. For residential customers, the practical incentive is the high retail electricity rate itself — at P12–13/kWh, self-consumed solar provides immediate savings, and some local government units offer real property tax exemptions for homes with renewable energy installations.
Payback
Simple payback is the system price divided by annual savings. The price side depends on equipment quality, installation complexity, and rebates. The savings side depends on your electricity usage, the buy rate per kWh, and the feed-in tariff for exported energy.
Simple payback calculation
Electricity rates & feed-in tariffs
Philippine residential electricity rates are among the highest in Southeast Asia. Meralco (serving Metro Manila and surrounding provinces) charges approximately P12–13 per kWh all-in, with the generation charge making up the largest component and fluctuating monthly based on power supply contracts and spot market prices. Outside Meralco's franchise, electric cooperatives charge similar or slightly lower rates. Under the DOE's net metering programme, excess solar exported to the grid is credited at the generation charge rate only (approximately P7/kWh), not the full retail rate — meaning self-consumed solar is worth roughly twice as much as exported solar. This makes sizing your system to match daytime consumption the most cost-effective approach, with typical payback periods of 5–7 years for well-sized residential systems.
