Risun 340 340W Polycrystalline Solar Panel
Model No. 340 | Polycrystalline | 144 Cells | On-grid | 1500V System Voltage
Product Overview
The Risun 340 is a reliable polycrystalline solar panel designed for consistent power generation and long-term value. It delivers a maximum output of 340 Wp with a module efficiency of 17.1 percent. This model is built for installations that need dependable performance, stable electrical characteristics, and strong durability. The panel uses 144 cells and a robust 2000 x 992 x 40 mm structure. It is suitable for commercial and residential projects where proven solar technology is preferred. The 10-year product warranty and 25-year power warranty add further confidence for buyers seeking a durable solar solution.
Key Benefits
Strong power output: The module delivers 340 Wp for steady energy production in everyday solar applications.
Durable construction: Tempered glass, an anodized aluminium frame, and IP67 protection support long service life.
High system compatibility: A maximum system voltage of 1500V supports modern solar installations and design flexibility.
Reliable temperature behavior: Low temperature coefficients help maintain output during changing weather conditions.
Practical installation format: The 40 mm frame and 22 kg weight make handling straightforward for qualified installers.
How It Works
The Risun 340 solar panel converts sunlight into usable electricity through its polycrystalline silicon cells. When sunlight reaches the cells, electrical current is generated and passed through the module circuitry. The panel is engineered to deliver stable performance at the maximum power point, which helps support efficient energy harvesting throughout the day. Its electrical ratings, protective components, and structural materials work together to create dependable operation. The junction box, cable design, and frame construction also contribute to safe power transmission and system integration. This design supports consistent output in a wide range of installation environments.
Photovoltaic generation: Sunlight activates the polycrystalline cells, which produce direct current electricity. The module is built to convert solar energy efficiently under standard operating conditions.
Power transfer: The panel sends energy through its 4 mm² cable and junction box. This supports secure and reliable connection to the broader solar system.
Protection and durability: Tempered glass, IP67 protection, and an anodized aluminium frame help the module handle outdoor exposure. These features improve resilience during long-term use.
