Solar Panel Installation Cost by System Size

System size is the primary cost driver, measured in kilowatt-peak (kWp). Ranges below are all-in estimates covering panels, inverter, mounting, wiring, labor, permits, and net metering assistance.

System Size	Best For	Monthly Bill	Est. Cost Range	Est. Monthly Savings	Payback
3 kWp	Small home	₱3K–₱5K	₱200,000–₱280,000	₱2,000–₱3,500	5–8 yrs
5 kWp	Medium home	₱5K–₱8K	₱350,000–₱480,000	₱3,500–₱5,500	5–8 yrs
8 kWp	Large home	₱8K–₱12K	₱560,000–₱680,000	₱5,500–₱8,000	5–8 yrs
10 kWp	Large home/business	₱12K–₱20K	₱700,000–₱900,000	₱8,000–₱12,500	4–7 yrs

What Does the Cost Include?

Solar Panels (40–50% of Total)

Tier 1 panels from LONGi, JA Solar, Canadian Solar, and Jinko Solar with 25-year linear performance warranties.

Inverter (15–25% of Total)

String inverters for standard configurations. Microinverters for shaded roofs. Hybrid inverters for battery-ready systems.

Mounting System (10–15%)

Typhoon-rated racking meeting Philippine wind load requirements.

Wiring and Protection (5–10%)

DC and AC wiring, disconnect switch, circuit breaker, surge protection, and conduit per Philippine Electrical Code.

Installation Labor (10–15%)

Professional installation supervised by a PRC-licensed electrical engineer.

Permits and Net Metering (5–8%)

Building Permit, Electrical Permit, CFEI, and complete Meralco net metering application. DIMC fee shall not exceed ₱3,000 for residential.

Factors That Affect Your Final Cost

Roof Area and Orientation

South-facing roofs produce the highest output. Limited area may require higher-efficiency monocrystalline panels.

Shading Conditions

Heavy shading may require microinverters. A shading analysis is conducted at every site assessment.

Panel Technology

Monocrystalline (19–22% efficiency) costs more but needs fewer panels. Polycrystalline (15–17%) needs more roof space.

Inverter Type

String inverters are lowest cost. Microinverters cost 20–40% more. Hybrid inverters add ₱30,000–₱80,000 but enable future battery storage.

Electrical Panel Condition

Outdated distribution boards may need upgrades. Quoted separately from the solar installation.

Roof Structure and Access

Steep or complex roofs and scaffold requirements add labor cost. All conditions evaluated during the free site assessment.

Solar Panel Savings and Return on Investment

SAVE
