Flagsun Green Power FSMH144-400W-G1 Monocrystalline Solar Panel
FSMH144-400W-G1 | Monocrystalline | 144 Half-Cell | Mono | 1500V System Voltage
Product Overview
The Flagsun Green Power FSMH144-400W-G1 Monocrystalline Solar Panel delivers exceptional energy performance for residential and commercial applications. This premium 400-watt panel features advanced monocrystalline technology with 144 high-efficiency cells optimized for maximum power output. Its robust design ensures reliable operation in diverse environmental conditions while maintaining a high module efficiency of 19.9 percent. The panel is engineered with a temperature coefficient of -0.355 percent per degree Celsius, ensuring minimal power loss during hot weather. Weighing only 21.5 kilograms, it offers an ideal balance between durability and ease of installation. The IP68-rated junction box provides superior protection against water and dust ingress. This solar panel is manufactured by Flagsun Green Power Co., Ltd. in China, a trusted global supplier of renewable energy solutions since 2014.
Key Benefits
High Power Output: Generates 400 watts of peak power for efficient energy generation in limited space.
Superior Efficiency: Achieves 19.9 percent module efficiency to maximize sunlight conversion into electricity.
Temperature Resilience: Low temperature coefficient minimizes power loss during high-temperature operation.
Durability & Protection: IP68 junction box and robust construction ensure long-term reliability in harsh weather.
Lightweight Design: 21.5 kg weight simplifies installation while maintaining structural integrity.
How It Works
The Flagsun Green Power FSMH144-400W-G1 Monocrystalline Solar Panel converts sunlight into usable electricity through the photovoltaic effect. When photons from sunlight strike the monocrystalline silicon cells, they excite electrons, creating a flow of direct current electricity. This DC power is then collected by the internal busbars and transmitted through the junction box to external inverters. The panel's high efficiency ensures that a significant portion of incident solar energy is converted into electricity. Its optimized cell design minimizes energy losses and maximizes output under varying light conditions.
Photovoltaic Conversion: Sunlight photons excite electrons in monocrystalline cells to generate direct current electricity. This process occurs instantly upon exposure to solar radiation.
Current Collection: Busbars collect the generated current from each cell and channel it to the junction box. The IP68-rated box protects connections from environmental damage.
Power Transmission: Electrical current flows through MC4 connectors to external inverters for AC conversion. The 300mm cable length ensures flexible installation options.
