Flagsun FSM636-190W 190W Monocrystalline Standard Solar Panel
Model FSM636-190W | Monocrystalline | 36 Full Cells | Monofacial | 1000V System Voltage
Product Overview
The Flagsun Green Power FSM636-190W monocrystalline solar panel delivers reliable 190 W power output for small to medium systems. It is designed for off‑grid, backup, and residential applications that demand stable performance and long service life. High efficiency monocrystalline cells help maximize energy harvest even on limited roof or ground space. The module operates within a wide temperature range from -40 to 85 °C for year round use. A panel efficiency up to 18.9 percent supports excellent power density per square meter. Power tolerance from 0 to plus 3 percent ensures dependable output with reduced performance risk. Tempered glass and an anodized aluminium frame add mechanical strength and weather protection. The FSM636-190W sits in a versatile 180 to 200 W product range, giving system designers flexible matching options. It is manufactured in China by Flagsun Green Power Co., Ltd., a specialist in cost effective solar modules. This robust design makes the panel a practical choice for cabins, RV systems, telecom loads, and small grid tie arrays.
Key Benefits
High efficiency power density: Panel efficiency up to 18.9 percent allows more power from compact mounting areas.
Reliable output tolerance: A 0 to plus 3 percent power tolerance supports consistent field performance over time.
Stable electrical performance: Optimized Vmpp at 18.3 V and Impp at 10.38 A simplify system matching and controller sizing.
Robust mechanical design: 3.2 mm tempered glass and an anodized aluminium frame enhance durability in outdoor conditions.
Wide operating temperature range: The module operates from -40 to 85 °C for reliable service across harsh climates.
Versatile power range options: The 180 to 200 W series supports flexible string design and project optimization.
How It Works
This monocrystalline solar panel converts sunlight directly into usable DC electricity through high purity silicon cells. When sunlight reaches the cell surface, photons transfer energy to electrons in the semiconductor. These energized electrons move through an internal electric field to create current flow. At the array level, panels are wired in series or parallel to reach the desired voltage and current. The FSM636-190W delivers 190 W at standard test conditions, with Vmpp at 18.3 V and Impp at 10.38 A. Its open circuit voltage of 23 V and short circuit current of 10.89 A define system design limits. Temperature coefficients control how power changes under real operating temperatures. The tempered glass and aluminium frame protect the cells while allowing high light transmission. Energy produced by the panel is normally routed to a charge controller, hybrid inverter, or DC load. From there it can be stored in batteries, converted to AC power, or consumed directly on site.
Monocrystalline cell conversion: High purity monocrystalline cells absorb incoming sunlight across the front surface area. An internal junction separates charge carriers and drives electrons into the external circuit. This process yields stable DC output suitable for battery charging and inverters. The 18.9 percent module efficiency helps maximize energy yield under standard conditions.
Voltage and current operating point: The module operates around its maximum power point at 18.3 V and 10.38 A. MPPT charge controllers or inverters track this point to extract maximum available power. Open circuit voltage at 23 V provides headroom for cold conditions and wiring losses. The short circuit current of 10.89 A defines conductor and protection device sizing.
Thermal behavior and reliability: Power output decreases slightly as cell temperature rises above test conditions. The temperature coefficient of Pmax is -0.43 percent per degree Celsius, managing performance loss. Voc changes with a coefficient of -0.34 percent per degree Celsius, affecting cold weather voltage. Isc increases marginally with a 0.049 percent per degree Celsius coefficient, maintaining current stability.
