Types of Solar Panels
The fundamental types of solar panels for both residential and commercial are defined by solar cell composition: Monocrystalline, Polycrystalline, and Thin-Film.
- Monocrystalline: Single, high-purity silicon crystal; most efficient; higher cost; uniform dark/black look; best when roof space is limited.
- Polycrystalline: Multiple fused silicon fragments; slightly less efficient; more affordable; distinct blue, speckled appearance.
- Thin-Film: PV material on glass/plastic/metal; flexible/lightweight; lowest efficiency; good where space/weight or form factor matters.
Other Notable Types
- Bifacial: Captures light from front and back to boost yield.
- PERC: Enhanced cell structure for improved efficiency.
- CPV: Uses optics to concentrate sunlight onto high-efficiency cells (specialized).
How to Choose
- Residential: Balance efficiency, aesthetics, and size/output for your home.
- Commercial: Maximize generation and cost-efficiency; consider larger, high-efficiency or bifacial.
