Waaree Energies WSMD-400 400W PERC Monocrystalline Solar Panel
WSMD-400 | PERC Technology | 144 Monocrystalline Cells | Mono | 1500V System Voltage
Product Overview
The Waaree Energies WSMD-400 400W PERC Monocrystalline Solar Panel delivers exceptional energy performance for residential and commercial installations. This high-efficiency module features 144 premium monocrystalline cells utilizing PERC technology to maximize light absorption. Its robust design ensures reliable operation across diverse environmental conditions with a temperature coefficient of -0.37%/°C for Pmax. The panel achieves a remarkable 19.87% efficiency rating, optimizing power density at 198.7 Wp/m². Manufactured by Waaree Energies Ltd in India, it supports a maximum system voltage of 1500V for flexible array configurations. The anti-reflection coated tempered glass protects against physical damage while enhancing light transmission. This solar solution is ideal for maximizing renewable energy generation on limited roof spaces.
Key Benefits
High Efficiency Output: Achieves 19.87% module efficiency to maximize energy generation per square meter.
PERC Technology: Utilizes Passivated Emitter and Rear Cell design for enhanced light absorption and lower degradation.
Robust Durability: Features 3.2mm tempered glass with anti-reflection coating for superior weather protection.
Low Temperature Sensitivity: Maintains performance with a Pmax temperature coefficient of -0.37%/°C in hot climates.
Long Warranty Coverage: Includes 12-year product warranty and 25-year power warranty ensuring 81.9% output retention.
How It Works
The Waaree WSMD-400 solar panel converts sunlight into usable electricity through the photovoltaic effect. Sunlight photons strike the 144 monocrystalline silicon cells, exciting electrons to create an electric current. The PERC technology adds a passivation layer on the rear side, reducing electron loss and improving efficiency. This design allows the panel to capture more light energy, especially in low-light conditions. The generated direct current flows through the MC4 connectors to an inverter for conversion into alternating current. The panel operates efficiently between -40°C and 85°C, ensuring year-round energy production. Its high system voltage of 1500V enables flexible wiring for large-scale solar arrays.
Photon Absorption: Sunlight photons strike the monocrystalline cells to excite electrons and generate direct current electricity. The PERC layer minimizes electron recombination for higher efficiency.
Current Generation: Excited electrons flow through the internal circuit to create a measurable electric current at 10.02A. The voltage at maximum power reaches 40.07V under standard test conditions.
Energy Conversion: Direct current exits via MC4 connectors to an inverter that converts it to alternating current for home use. The panel maintains 91.65% output after 25 years of operation.
