Huayao PV HY455-M120BDD 455W Monocrystalline Solar Panel
Model HY455-M120BDD | Monocrystalline | 120 Cells | Mono | 1500V System Voltage
Product Overview
The Huayao PV HY455-M120BDD is a high-efficiency monocrystalline solar panel designed for dependable energy production. It delivers 455Wp of maximum power with 21.02% module efficiency. This model uses 120 cells and supports a 1500V maximum system voltage. Its compact frame, strong construction, and 30-year power warranty make it suitable for long-term solar projects. The panel is engineered for stable performance in demanding outdoor conditions. It is built for residential, commercial, and utility applications where reliable output matters.
Key Benefits
High Power Output: The module reaches 455Wp for strong daily energy generation.
Excellent Efficiency: Its 21.02% efficiency supports better space usage on rooftops and ground systems.
Long Warranty Coverage: A 15-year product warranty and 30-year power warranty add long-term confidence.
Durable Construction: An anodized aluminium frame and IP68 junction box improve durability and protection.
Wide Operating Range: The panel performs across temperatures from -40°C to 85°C.
How It Works
This monocrystalline solar panel converts sunlight into electricity through advanced photovoltaic cells. The 120-cell layout helps capture solar energy efficiently across the module surface. Its electrical design balances voltage and current for stable output under standard operating conditions. The panel is also built to maintain performance in varying weather and temperature conditions. With strong glass, a corrosion-resistant frame, and sealed junction box protection, the module is made for dependable long-term operation. The temperature coefficients help explain how performance changes as conditions shift during the day.
Photovoltaic Conversion: Sunlight strikes the monocrystalline cells and produces direct current electricity. This creates usable solar power for connected systems.
Electrical Output Balance: The panel produces 35.5V at maximum power and 12.82A current. This balance supports efficient string design.
Environmental Protection: The IP68 junction box and aluminium frame protect the module from outdoor exposure. This supports stable operation over time.
