Wondering how to calculate solar panel wattage per meter? This guide explains the power output of 2-meter solar panels, their real-world applications, and industry trends. Whether you're planning a rooftop installation or a commercial solar farm, we'll break down the numbers you need.
Understanding Solar Panel Wattage per Meter
A typical 2-meter solar panel generates 300-400 watts under standard test conditions (STC). This translates to 150-200 watts per linear meter, though actual output depends on three key factors:
- Cell efficiency (monocrystalline vs. polycrystalline)
- Sunlight intensity and geographic location
- Installation angle and shading
Pro Tip: New bifacial panels can boost output by 15-20% by capturing reflected light on both sides.
Solar Panel Power Density Comparison
| Panel Size | Total Wattage | Watts/Meter |
|---|---|---|
| 2m × 1m | 340W | 170W |
| 2.2m × 1.1m | 400W | 182W |
Industry Applications of 2-Meter Solar Panels
From residential rooftops to industrial complexes, 2-meter solar modules dominate multiple sectors:
- Residential: 8-12 panels can power average homes
- Commercial: Warehouses use 500+ panel arrays
- Agriculture: Solar pumps and irrigation systems
Case Study: Solar-Powered Cold Storage
A Vietnamese seafood company installed 240×2m panels (total 81.6kW) to maintain -25°C storage temperatures. The system:
- Covers 60% of energy needs
- Reduces diesel costs by $18,000/year
- Paid back in 4.7 years
Solar Technology Advancements
Recent breakthroughs are reshaping the industry:
- PERC cells achieving 22.8% efficiency
- Thin-film panels with 180W/m output
- Smart panels with micro-inverters
Did You Know? EK SOLAR's latest 2m dual-glass panel delivers 420W output with 30-year warranty, ideal for high-humidity coastal areas.
