220 Photovoltaic Panel Size A Comprehensive Guide for Solar Projects
Why 220W Solar Panel Dimensions Matter for Your Project
When planning solar installations, the 220 photovoltaic panel size often emerges as a sweet spot between power output and space efficiency. This guide will help you understand how these dimensions impact rooftop layouts, commercial arrays, and overall project economics.
Standard Dimensions of 220W Solar Panels
Most 220W panels measure approximately:
- Length: 1,650 mm (5.4 ft)
- Width: 990 mm (3.25 ft)
- Depth: 35 mm (1.38 in)
Comparative Analysis of 220W Panels
| Brand | Dimensions (mm) | Efficiency |
|---|---|---|
| Model A | 1650×990×35 | 18.2% |
| Model B | 1670×1000×40 | 17.8% |
Calculating Required Installation Space
Want to know how many 220W panels your roof can accommodate? Follow this simple formula:
"Total space = (Panel length × Panel width) × 1.3 (safety margin)"
Real-World Application Example
A 5kW system using 220W panels would need:
- 23 panels (220W × 23 = 5,060W)
- Approximately 32.5㎡ of roof space
Balancing Efficiency and Physical Size
Recent advancements in PERC cell technology allow manufacturers to maintain high efficiency ratings while keeping panel dimensions manageable. The latest 220W models now achieve up to 19.3% conversion efficiency – comparable to many 300W+ panels from five years ago.
Commercial Installation Case
EK SOLAR recently completed a 100kW warehouse installation using 220W panels. The compact size enabled:
- 15% more panels within the same roof area
- Reduced mounting hardware costs
- Simplified maintenance access
FAQ: 220 Photovoltaic Panel Dimensions
Q: Can I mix different panel sizes in one system?
A: While possible, we recommend using identical panel dimensions for optimal performance.
Q: How does panel thickness affect installation?
A: Thinner panels (30-35mm) generally allow for easier mounting and better heat dissipation.
