Summary: Discover the technical specifications, industry applications, and design advantages of double-glass bifacial solar modules. This guide explores key dimensions, performance metrics, and real-world use cases for renewable energy professionals.

Why Double-Glass Bifacial Modules Matter in Solar Energy

As solar projects demand higher efficiency and durability, double-glass bifacial modules have become a game-changer. These panels generate power from both sides by capturing direct sunlight and albedo reflection, making them ideal for commercial solar farms and industrial installations.

Key Technical Specifications

• Power Output: 400W to 670W (depending on cell configuration)
• Front/Rear Efficiency: 21.5% front side, +10-25% rear gain
• Dimensions:
  • Standard 144-cell: 2278mm x 1134mm x 35mm
  • Half-cut 132-cell: 2094mm x 1038mm x 30mm
• Weight: 28.5kg to 35.2kg per module

Industry Applications: Where Bifacial Tech Shines

From desert solar farms to urban carports, here''s how different sectors benefit:

Application	Performance Gain	Typical Configuration
Utility-scale plants	12-18% more annual yield	Vertical east-west mounting
Commercial rooftops	8-15% energy boost	3.5m elevated structures

Case Study: 50MW Project in Arizona

A solar farm using 72-cell bifacial modules achieved:

• 19.2% higher annual output vs. monofacial panels
• ROI improved by 2.4 years
• LID (Light Induced Degradation) below 1% after 3 years

Design Considerations for Optimal Performance

Three critical factors determine success with bifacial technology:

1. Mounting Height: Minimum 1m clearance for rear-side light capture
2. Surface Albedo: ≥0.5 reflectance value recommended
3. Row Spacing: 2x module height to minimize shading

"The true value of bifacial modules isn''t just in specs sheets – it''s about system-level optimization." - Solar Engineering Digest, 2023 Industry Report

Future Trends: What''s Next for Bifacial Tech?

Emerging developments include:

• Ultra-thin glass (1.6mm front/2.0mm rear)
• Seamless microinverter integration
• AI-powered yield prediction software

Recent NREL data shows bifacial modules capturing 37% of new utility-scale installations in 2024 – up from just 12% in 2020.

FAQ: Your Top Questions Answered

Q: Do bifacial modules require special maintenance? A: No more than standard panels, but ground surface maintenance impacts rear-side performance.

Q: Can I retrofit existing structures? A: Yes, if mounting systems allow sufficient rear-side clearance and tilt adjustment.

Final Thoughts

Understanding double-glass bifacial module specifications goes beyond physical dimensions – it''s about maximizing energy harvest through smart system design. With 20-30% higher lifetime yields than conventional panels, this technology is reshaping solar economics across industries.
