Waaree Energies WSM-3 395Wp PERC Monocrystalline Solar Panel
WSM-3 | PERC Technology | 72 Mono Cells | Monofacial | 1500V System Voltage
Product Overview
The Waaree Energies WSM-3 395Wp PERC Monocrystalline Solar Panel delivers exceptional energy performance for residential and commercial solar projects. This high-efficiency module utilizes advanced PERC cell technology to maximize power output even in low-light conditions. Its robust monocrystalline silicon construction ensures long-term durability and minimal degradation over decades of operation. The panel features a sleek design with an anodized aluminum frame that withstands harsh weather environments. With a maximum power rating of 395 Wp, it offers superior energy generation compared to standard panels. The 19.83% module efficiency allows for compact system designs while maintaining high output. This Indian-made product is manufactured by Waaree Energies Ltd, a leading solar PV module producer. It includes IP68-rated junction boxes and MC4 connectors for secure, weatherproof connections. The anti-reflection coated tempered glass protects cells while optimizing light absorption. Ideal for rooftops and ground mounts, this panel combines reliability with cutting-edge solar technology.
Key Benefits
High Power Output: Generates 395 Wp of electricity for maximum energy production per panel.
Advanced PERC Technology: Enhances cell efficiency to capture more sunlight and improve performance in dim light.
Superior Efficiency: Achieves 19.83% module efficiency for compact system designs with high output.
Long-Term Warranty: Includes 10-year product warranty and 25-year power output guarantee at 80%.
Weatherproof Design: Features IP68 junction boxes and tempered glass for protection against rain and dust.
How It Works
This solar panel converts sunlight directly into usable electricity through the photovoltaic effect. When photons from sunlight strike the monocrystalline silicon cells, they excite electrons to create an electric current. The PERC technology adds a passivation layer to reduce electron loss and boost overall efficiency. This current flows through the panel's internal wiring to the junction box for external connection. The MC4 connectors ensure a secure, weatherproof link to the rest of the solar system. The anti-reflection coating on the glass maximizes light entry while minimizing surface reflection. This process enables consistent energy generation throughout the day under varying light conditions.
Photon Absorption: Sunlight photons hit the silicon cells and release electrons to generate electrical current. The anti-reflection glass coating ensures maximum light penetration into the cell layer.
Electron Flow: Excited electrons move through the internal circuit to create a direct current. The PERC passivation layer prevents electron recombination to maintain higher efficiency levels.
Current Collection: The generated current reaches the IP68 junction box for safe external connection. MC4 connectors then link the panel to the solar inverter or battery system.
