Why the Temperature Coefficient Matters for Solar Modules

When evaluating solar panel performance, the double glass module temperature coefficient often becomes a critical talking point. But what does this term really mean? Simply put, it measures how much a solar panel's efficiency drops as temperatures rise. For instance, if your module has a temperature coefficient of -0.35%/°C, its output decreases by 0.35% for every degree Celsius above 25°C. Now imagine this happening in desert installations where ambient temperatures regularly hit 45°C – that's a 7% efficiency loss right there!

Key Factors Influencing Temperature Coefficient

• Material selection: Double-glass modules typically use ultra-clear glass with low iron content.
• Encapsulant quality: Advanced EVA or POE materials reduce thermal resistance.
• Frame design: Aluminum alloys with thermal breaks minimize heat transfer.

Real-World Performance Data Analysis

Let's examine field data from three installation types:

Notice how temperature variations significantly impact energy harvest – this is why manufacturers are racing to develop modules with coefficients below -0.30%/°C.
