Summary: Understanding photovoltaic panel specifications is critical for optimizing solar projects. This guide explores 280W solar panel parameters, industry applications, and data-backed insights to help professionals make informed decisions.
Why 280W Photovoltaic Panels Dominate Mid-Scale Installations
With global solar capacity reaching 1.6 TW in 2023 (SEIA data), mid-power panels like 280W modules have become the backbone of commercial solar systems. Let's break down their technical advantages:
- Optimal power density: 17.3% average efficiency rating
- Temperature coefficient: -0.35%/°C (outperforms 80% of polycrystalline panels)
- Dimension standardization: 65" x 39" x 1.4" (compatible with most mounting systems)
Pro Tip: 280W panels deliver 8% better ROI than 250W models in areas with limited roof space – perfect for urban solar installations.
Technical Specifications Breakdown
| Parameter | Value | Industry Average |
|---|---|---|
| Maximum Power (Pmax) | 280W | 265-300W |
| Open Circuit Voltage | 40.5V | 38-42V |
| Short Circuit Current | 9.12A | 8-9.5A |
Real-World Applications: Where 280W Panels Shine
These panels have powered diverse projects worldwide:
- Agricultural Solutions: A 500-panel dairy farm installation in Wisconsin reduced energy costs by 62%
- Commercial Rooftops: 1.2MW system using 280W panels achieved 4-year payback period
- Hybrid Systems: Combined with lithium batteries for 24/7 power supply in remote clinics
Installation Considerations
While 280W panels offer versatility, professionals should note:
- Require 30A charge controllers for optimal performance
- Best paired with 48V battery banks
- Wind load rating: 130 mph (meets Florida hurricane codes)
Case Study: A 280W panel array in Arizona maintained 94% output after 3 years of desert operation – outperforming warranty expectations.
FAQs: Photovoltaic Panel Specifications
- Q: How does temperature affect 280W panel performance?A: Output decreases 0.35% per °C above 25°C – better than most polycrystalline modules.
- Q: What maintenance do these panels require?A: Semi-annual cleaning and annual electrical checks ensure optimal performance.
