Types of solar panels
available in the Philippines

Compare monocrystalline, bifacial, and polycrystalline solar panels — with Philippine-specific recommendations for 2026.

Monocrystalline Solar Panels

Most Popular

Monocrystalline panels are cut from a single silicon crystal, giving them the highest purity and efficiency. They are the top choice for Filipino homeowners with limited roof space who need maximum output per square meter.

Efficiency
20–23%
Lifespan
25–30 years
Price (per panel)
₱4,500–₱10,500 per panel
Pros
Highest efficiency in hot Philippine climate
Best performance in low-light / cloudy days
Sleek all-black or dark-blue aesthetic
25+ year performance warranty standard
Cons
×Higher upfront cost vs polycrystalline
Available brands: Jinko Solar, Trina Solar, Canadian Solar, Longi, Seraphim

Bifacial Solar Panels

Best for Flat Roofs

Bifacial panels have a transparent back sheet that captures reflected light from the roof surface. In the Philippines, light-colored flat roofs (common in concrete bungalows) can boost output by 15–30% compared to standard panels.

Efficiency
22–26%
Lifespan
25–30 years
Price (per panel)
₱7,500–₱13,000 per panel
Pros
Generate power from both front and back
10–30% more energy in reflective environments
Ideal for white flat roofs common in PH
Higher energy yield per square meter
Cons
×Requires elevated mounting for bifacial gain
×Higher cost than standard mono
Available brands: Jinko Tiger Neo, Longi Hi-MO 6, Canadian Solar BiHiKu

Polycrystalline Solar Panels

Budget Option

Polycrystalline panels are made from multiple silicon fragments melted together. They are cheaper but less efficient and degrade faster in high-heat environments like the Philippines. We generally recommend monocrystalline instead.

Efficiency
15–17%
Lifespan
20–25 years
Price (per panel)
₱2,800–₱5,500 per panel
Pros
Lower upfront cost
Widely available in the Philippines
Cons
×Lower efficiency in heat (degrades faster)
×Less suited to hot Philippine climate
×Larger footprint per kW
Available brands: Generic / local brands

Other panel types: solar thermal, thin-film & specialty

Solar Thermal Panels (Water Heating)
Heating Only

Uses sunlight to heat water directly (not electricity). Common for swimming pools, showers, and industrial hot water. More efficient than PV for heating applications — 60–70% efficiency vs 20% for PV panels.

Cheaper than PV per kWh of heat
Works well for pool heating in PH
Simple technology, lasts 20+ years
Note: Solar thermal does not generate electricity. For pool heating, it is excellent. For general home use, PV + heat pump is more versatile.
Thin-Film Solar Panels
Low Efficiency

Made by depositing photovoltaic material onto glass, plastic, or metal. Lightweight and flexible but much less efficient (10–13%) than crystalline panels. Rarely used for residential in the PH.

Lightweight — less roof load
Works in high heat (low temp coefficient)
Flexible substrates available
Note: Efficiency is too low for most Philippine residential roofs. Monocrystalline is a better investment for limited roof space.
Solar Panel Materials & Construction

Standard panels use 6 layers: tempered glass (3.2mm anti-reflective), EVA encapsulant, silicon solar cells, backsheet (white/transparent for bifacial), aluminum frame, and junction box with MC4 connectors.

Tempered glass withstands 2,400Pa wind load (typhoon-rated)
Aluminum frame is corrosion-resistant (ideal for PH humidity)
MC4 connectors are waterproof for monsoon rain
Solar Water Heater Panels
Hot Water

Specifically designed for heating domestic water using the sun. Evacuated tube collectors and flat plate collectors are the two main types. Common in PH for hotels, resorts, and residential showers.

Reduces electric water heater usage by 60–80%
Simple maintenance
Good ROI for high-hot-water homes
Note: Different from solar PV panels. For hot water only, not electricity generation. SolarX offers both PV and thermal solutions.

Solar panel type FAQs

Monocrystalline solar panels are the best choice for most Filipino homes. They have the highest efficiency (20–23%), perform better in heat and partial shade, and have a 25+ year lifespan. Bifacial panels are best for flat, light-colored roofs.
