Waaree Energies WSD-400 400Wp PERC Polycrystalline Solar Panel
WSD-400 | PERC Technology | 144 Polycrystalline Cells | Mono | 1500V System Voltage
Product Overview
The Waaree Energies WSD-400 400Wp PERC Polycrystalline Solar Panel delivers exceptional energy generation for residential and commercial projects. This robust module features 144 high-quality polycrystalline cells optimized with PERC technology for enhanced efficiency. It achieves a peak power output of 400 Wp with a module efficiency of 18.4%. The panel is designed to withstand harsh climatic conditions with a temperature coefficient of -0.38%/°C for power. Its durable construction includes an anodized aluminum frame and 3.2 mm tempered glass with anti-reflection coating. The WSD-400 offers a 10-year product warranty and a 25-year performance warranty guaranteeing 80.7% output. This solar panel is ideal for maximizing energy savings on limited roof spaces while ensuring long-term reliability.
Key Benefits
High Power Output: Generates 400 Wp of power to significantly reduce electricity bills for large energy consumers.
Enhanced Efficiency: Achieves 18.4% module efficiency using PERC technology to maximize energy from available sunlight.
Long-Term Warranty: Backed by a 10-year product warranty and 25-year performance warranty ensuring 80.7% output retention.
Weather Resistance: Features an IP68 junction box and tempered glass to withstand heavy wind, snow loads, and extreme temperatures.
Low Degradation Rate: Maintains power with a low annual degradation rate of 0.77% for sustained energy production over decades.
How It Works
The Waaree Energies WSD-400 solar panel converts sunlight into electricity through the photovoltaic effect. Sunlight photons strike the 144 polycrystalline silicon cells within the module. These cells absorb the energy and release electrons to generate an electric current. The PERC technology enhances this process by capturing more light on the cell's rear side. This design increases the overall efficiency and power output compared to standard panels. The generated direct current flows through the MC4 connectors to your inverter system. The inverter then converts this current into usable alternating current for your home or business. This continuous cycle ensures reliable renewable energy generation day and night.
Photovoltaic Conversion: Sunlight photons hit the polycrystalline cells to release electrons and create a direct electric current. This process is the core mechanism of solar energy generation.
PERC Enhancement: The Passivated Emitter and Rear Cell layer captures reflected light to boost efficiency. This technology increases power output by utilizing more of the available solar spectrum.
Current Transmission: Generated electricity flows through the IP68 rated junction box and MC4 connectors safely. The system then transmits power to the inverter for conversion into usable energy.
