Is My Home Ready for Solar?
Most homes in Metro Manila, Cavite, Laguna, and Bulacan are suitable for residential solar panel installation. SolarPro Install assesses each property individually to confirm suitability and determine the correct system size as part of the same solar panel installation process used across the Philippines. Four factors determine whether your home qualifies and what size system is appropriate — the full methodology behind that sizing decision is covered in our guide to solar panel system sizing for your property.
Roof Type
SolarPro Install installs on concrete, metal, clay tile, and asphalt shingle roofs. Our typhoon-rated mounting systems are compatible with all common residential roof types in the Philippines. Flat roofs can be fitted with tilt frames at the optimal angle for maximum output.
Roof Area Required
A 3 kWp system requires approximately 18 to 20 square meters of unshaded roof area. A 5 kWp system requires approximately 28 to 32 square meters. SolarPro Install assesses your available roof area during the free site assessment and recommends the maximum viable system size.
Property Ownership
Solar panel installation requires that you own the property or have the property owner’s written authorization. Meralco net metering registration is tied to the property’s Meralco account. Renters may install solar with the property owner’s consent, though ownership of the system needs to be clarified in the tenancy agreement.
Monthly Meralco Bill
The strongest financial case for residential solar is a monthly Meralco bill of ₱3,000 or above. Lower bills can still benefit from solar, though the payback period extends. SolarPro Install will give you an honest savings projection during the site assessment based on your actual 12 months of Meralco billing data.
Residential System Sizes and What They Offset
Residential solar systems in the Philippines typically range from 3 kWp to 10 kWp depending on roof area and monthly consumption. Here is how each size matches to a typical Meralco customer. The solar panel installation cost in the Philippines for each size below is an all-in figure covering panels, inverter, mounting, permits, and net metering assistance.
3 kWp
Small to Medium Home — Bill ₱3,000 to ₱5,000/month

What Is Included in a Residential Solar Installation
Every SolarPro Install residential installation is a complete, turnkey package. Nothing is left for you to source or coordinate separately. Eight components are included in every project at the quoted price.
Site Assessment and System Design
An engineer visits your property to measure roof area, assess orientation and shading, review 12 months of Meralco bills, and design a system sized to your specific consumption and roof conditions. A
site shading assessment is conducted at every visit to determine whether microinverters or a standard string inverter is right for your roof.
Inverter
The
solar inverter type for your Philippines installation depends on your roof configuration — string inverters for standard setups, microinverters for shaded or complex rooftops, and hybrid inverters for battery-ready systems. Brands: Growatt, Goodwe, Huawei, Fronius, SMA.
Typhoon-Rated Mounting System
Racking engineered to meet Philippine wind load requirements. Compatible with concrete, metal deck, clay tile, and asphalt shingle roofs. Designed to withstand typhoon-force winds.
Complete Wiring and Electrical Work
DC and AC wiring, disconnect switch, surge protection, and circuit breaker per Philippine Electrical Code, supervised and signed off by a PRC-licensed Professional Electrical Engineer.
LGU Permits and CFEI
Building Permit and Electrical Permit filed with your LGU on your behalf. CFEI coordination included as required for the Meralco net metering application.
Meralco Net Metering Application
Solar installation for Meralco customers in the Philippines requires a Meralco-accredited installer to file the net metering application. We handle the complete submission — Application Form, NMA, COC Fee, DIS follow-up, DIMC fee coordination, and bi-directional meter installation. Credits begin from the first billing period after energization.
Battery Storage Option
Solar battery storage in the Philippines ranges from 5 kWh for basic backup during outages to 15 kWh or more for homes that need air conditioning coverage overnight. SolarPro Install sizes battery capacity based on your specific backup load requirements.
Residential Solar in the Philippines: Physical Installation Takes 1 to 3 Days.
Residential Solar Installation Process
The complete solar panel installation process in the Philippines runs ten stages from site assessment to Meralco net metering activation. For a standard residential property, physical installation takes one to three days. The full process from signing to energization typically takes two to four months — LGU permit processing and Meralco’s Distribution Impact Study account for most of that window.

Residential Solar Savings Summary
Residential solar savings accumulate from two sources: direct consumption of solar electricity during the day and net metering credits for surplus electricity exported to the Meralco grid. The figures below represent estimated combined monthly savings from both sources. The solar savings available to Meralco customers in the Philippines grow with each Meralco rate increase — a flat-rate 25-year projection understates the actual lifetime return.
3 kWp₱2,000–₱3,500Est. monthly savings
5 kWp₱3,500–₱5,500Est. monthly savings
8 kWp₱5,500–₱8,000Est. monthly savings
10 kWp₱8,000–₱12,500Est. monthly savings
Payback period: 5 to 8 years. After payback, the system generates electricity for free for the remaining 15 to 20 years of its 25-year warranted life. The complete guide to solar panel lifespan in the Philippines covers year-by-year output projections and degradation data for Tier 1 panels. Solar panels and inverters are VAT-exempt under Republic Act 9513.
Frequently Asked Questions About Residential Solar Installation
Can solar panels be installed on any type of roof?
Yes. SolarPro Install installs on concrete, metal deck, clay tile, and asphalt shingle roofs using typhoon-rated mounting systems. The roof must be in good structural condition. Our site assessment includes a roof structural evaluation before any system is designed.
How many solar panels does my home need?
A 3 kWp system uses 8 to 10 panels. A 5 kWp system uses 12 to 14 panels. A 10 kWp system uses 22 to 26 panels. The exact count depends on the panel wattage chosen. SolarPro Install determines the right panel count and configuration during the free site assessment based on your roof area and consumption.
Will solar panels damage my roof?
A properly installed solar mounting system does not damage the roof. Penetration points are sealed with waterproof materials. SolarPro Install uses mounting systems designed for Philippine weather conditions including typhoons and heavy rainfall.
Do solar panels work during a power outage?
Standard on-grid solar systems automatically shut down during a power outage as a safety requirement for Meralco linemen.
Solar battery storage in the Philippines paired with a hybrid inverter continues to power your home during outages — capacity ranges from 5 kWh for basic loads to 15 kWh or more for overnight use with air conditioning.
Can I install solar if I live in a subdivision or village?
Yes, in most cases. Some homeowners associations have guidelines on the appearance of rooftop installations. SolarPro Install can provide documentation required by HOAs and advises on compliance with subdivision rules before installation begins. For townhouse owners specifically, the guide to
solar panel installation for townhouses in the Philippines covers party wall routing, roof area constraints, and HOA documentation requirements for multi-unit developments.
Can solar panels be installed in a condominium?
Condo solar is possible but requires additional steps not needed for landed properties. The guide on
solar panel installation for condominiums in the Philippines covers three scenarios: Condominium Corporation building-wide systems, penthouse units with exclusive-use roof rights, and individual units with direct Meralco accounts.
What warranty does the solar system come with?
Solar panels carry a 25-year linear performance warranty guaranteeing at least 80 percent output at year 25. Inverters are typically warranted for 5 to 10 years with extended warranty options. The mounting system and workmanship are warranted by SolarPro Install. Full warranty documentation is provided at system handover.
