Flagsun Green Power FSMH144-405W-G1 Monocrystalline Monofacial Solar Panel
FSMH144-405W-G1 | Monocrystalline PERC | 144 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Flagsun Green Power FSMH144-405W-G1 Monocrystalline Monofacial Solar Panel delivers exceptional performance for residential and commercial energy systems. This high-efficiency module features 144 premium monocrystalline cells arranged in a robust half-cell design. Its maximum power output of 405 Wp ensures reliable energy generation even under varying weather conditions. The panel achieves an impressive efficiency rating of 20.2%, maximizing energy yield per square meter. Engineers designed this unit with superior temperature tolerance, operating effectively between 45±2 °C. Its compact dimensions of 2008x1002x30 mm allow for flexible installation on diverse roof structures. The lightweight design of 21.5 kg simplifies handling and mounting processes for installers. This solar panel represents a top choice for sustainable power solutions in China and globally.
Key Benefits
High Power Output: Delivers 405 Wp maximum power for efficient energy generation in all lighting conditions.
Superior Efficiency: Achieves 20.2% module efficiency to maximize energy yield from limited roof space.
Temperature Resilience: Operates reliably at 45±2 °C with minimal power loss due to temperature coefficients.
Robust Construction: Features IP 68 protection class and durable junction box for extreme weather resistance.
Easy Installation: Lightweight 21.5 kg design with standard dimensions simplifies mounting for any installer.
How It Works
This solar panel converts sunlight into usable electricity through the photovoltaic effect within its 144 monocrystalline cells. When photons strike the silicon surface, they excite electrons to create a flow of direct current. The half-cell design reduces internal resistance and minimizes power loss during energy transmission. Three bypass diodes in the junction box protect the system from shading or cell failure issues. The IP 68 sealed enclosure ensures the internal electronics remain safe from moisture and dust damage. This reliable mechanism provides consistent power for homes, businesses, and industrial facilities worldwide.
Photovoltaic Conversion: Sunlight photons excite electrons in monocrystalline silicon cells to generate direct current electricity. This process creates a continuous flow of energy for immediate use.
Half-Cell Technology: Splitting cells reduces internal resistance and lowers heat generation during operation. This design improves overall efficiency and extends the panel's operational lifespan significantly.
Protection System: Three bypass diodes prevent power loss when parts of the panel face shading. The IP 68 junction box shields electronics from water and dust exposure effectively.
