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.
