Greensun GSM445-144 445Wp PERC Monocrystalline Solar Panel
GSM445-144 | PERC Technology | 144 Half-Cell | Monocrystalline | 1500V System Voltage
Product Overview
The Greensun GSM445-144 445Wp PERC Monocrystalline Solar Panel delivers exceptional performance for residential and commercial installations. This high-efficiency module features advanced PERC technology to maximize energy yield even in low-light conditions. Its robust monocrystalline construction ensures long-term durability against harsh weather elements. The panel achieves a remarkable 20.1% efficiency rating, making it ideal for space-constrained rooftops. With a maximum power output of 445 Wp, it significantly boosts overall system capacity. Users benefit from a precise power tolerance ranging between 0% and +1%. The lightweight design at 24 kg simplifies mounting and reduces structural load requirements. Manufactured by Greensun Solar Energy Tech Co., Ltd in China, this product adheres to strict quality standards. It is part of a power range spanning 445 to 460 Wp for versatile system scaling.
Key Benefits
High Energy Efficiency: Achieves 20.1% module efficiency to maximize power generation per square meter.
Advanced PERC Technology: Utilizes Passivated Emitter and Rear Cell tech for superior low-light performance.
Precise Power Tolerance: Guarantees output between 0% and +1% to ensure reliable system sizing.
Lightweight Design: Weighs only 24 kg, reducing structural stress and easing installation logistics.
Low Temperature Coefficient: Maintains efficiency with a -0.4%/°C Pmax coefficient in hot climates.
How It Works
This solar panel converts sunlight into usable electricity through the photovoltaic effect within its 144 monocrystalline cells. The PERC layer on the rear side captures reflected light that standard cells would miss, boosting total energy output. When photons strike the silicon cells, they excite electrons to create a direct current flow. This current is then collected by the busbars and transmitted to the junction box for external connection. The panel's design minimizes resistive losses, ensuring maximum voltage reaches the inverter efficiently. Its robust construction protects internal components from moisture, dust, and thermal expansion over decades.
Photon Absorption: Sunlight photons hit the silicon cells, exciting electrons to generate direct current. This process occurs instantly upon exposure to light.
PERC Enhancement: The rear passivation layer reflects unused light back into the cell for a second absorption chance. This increases total current generation significantly.
Current Collection: Excited electrons flow through busbars to the junction box for external circuit connection. The system maintains high voltage stability under load.
