280Wp Photovoltaic Panel Specifications: Technical Guide & Applications
Understanding 280Wp Solar Panels: Key Features & Benefits
280Wp photovoltaic panels have become a popular choice for residential and small commercial solar projects due to their balanced efficiency and cost-effectiveness. These mid-power solar modules offer reliable energy output while maintaining compatibility with most rooftop mounting systems.
Technical Specifications Breakdown
- Power Output: 280 Watts peak (Wp) ±3%
- Cell Type: Monocrystalline PERC (Passivated Emitter Rear Cell)
- Dimensions: 1700mm × 1000mm × 35mm
- Weight: 18.5 kg
- Temperature Coefficient: -0.35%/°C
Pro Tip: The -0.35%/°C temperature coefficient means output decreases by just 3.5% for every 10°C temperature rise above 25°C – better than industry average.
Performance Analysis: Real-World Applications
Recent field tests show 280Wp panels maintain 92% efficiency after 25 years of operation. For a typical 5kW residential system:
| System Size | Annual Production | CO2 Reduction |
|---|---|---|
| 5kW (18 panels) | 6,500 kWh | 4.2 tons |
Installation Case Study: Urban Rooftop Project
A recent installation in Madrid using 280Wp panels achieved 21.8% system efficiency – 3% higher than local polycrystalline installations. The 8.4kW system:
- Reduced electricity bills by 85%
- Paid back installation costs in 6.2 years
- Withstood 120km/h winds during storm testing
Industry Trends & Technological Advances
The solar industry is moving toward higher efficiency modules without significant size increases. 280Wp panels represent the current sweet spot between:
- Power density (165W/m²)
- Manufacturing costs ($0.28/W)
- Installation flexibility
Did You Know?
Global demand for 270-300Wp panels grew 34% in 2023, driven by residential retrofits and commercial carport installations.
Frequently Asked Questions
Are 280Wp panels suitable for cloudy climates?
Yes, their low-light performance (85% output at 200W/m² irradiance) makes them effective in diffuse light conditions.
What maintenance do they require?
Basic cleaning 2-4 times yearly and annual electrical checks. Most systems include 12-year product warranty.
