Which Solar Panel Is Best in Singapore? A Complete Breakdown

When researching solar panels, you’ve probably come across terms like monocrystalline, polycrystalline, N-type, or P-type.If these sound confusing — don’t worry. This guide breaks them down in a simple, clear way so you can understand what truly matters for your home or building in Singapore.

Monocrystalline vs Polycrystalline Panels

Monocrystalline Panels

Monocrystalline panels are the most popular choice in Singapore, known for their superior performance and sleek appearance.

Pros:

• Highest efficiency

• Performs better in hot weather

• Long lifespan (25+ years)

• Modern, uniform black finish

Cons:

• Higher upfront cost

Polycrystalline Panels

Polycrystalline panels are a more budget-friendly alternative, though slightly less efficient.

Pros:

• More affordable

• Reliable and durable

Cons:

• Lower efficiency

• Reduced performance in high heat

Side-by-Side Comparison

Feature	Monocrystalline	Polycrystalline
Cost	Higher	Lower
Efficiency	More efficient	Less efficient
Lifespan	25+ years	25+ years
Temperature Performance	Better performance in heat	Less effective in heat

👉 In Singapore, homeowners and commercial buildings typically choose monocrystalline panels for higher performance and a cleaner look.

N-Type vs P-Type: What’s the Difference?

P-Type Solar Panels

• Older, widely used technology

• More affordable

• May experience Light-Induced Degradation (LID), which reduces efficiency over time

N-Type Solar Panels

• Higher efficiency (around 21–24%)

• Better performance in heat

• More resistant to degradation

• Higher long-term power output
