Model Bi-55-535 | Mono PERC | 144 Half-Cut Cells | Bifacial | 1500V System Voltage
The Waaree AHNAY Bi-55-535 535W bifacial monocrystalline solar panel delivers high output for modern projects. This premium AHNAY series module uses advanced mono PERC half-cut cells to maximize efficiency and reliability. Bifacial glass-glass construction captures light from the front and rear sides for higher yields. The panel is engineered for utility, commercial, and large residential arrays that demand strong performance. A robust 1500V system rating supports long strings and optimized BOS costs. Linear performance guarantees and low annual degradation help protect long term energy production. With a 12 year product warranty and power output assured to 82.05 percent at 30 years, this Waaree panel is designed for dependable energy generation. The Bi-55-535 offers an effective balance of power density, durability, and long term value for professional installers and asset owners.
High bifacial energy yield: Framed dual glass bifacial construction allows rear side generation for extra kWh per module. Higher backside gains can be achieved with reflective surfaces and optimized layout design.
Efficient 535W power class: Nameplate power of 535 watts with up to 20.78 percent efficiency reduces required roof or ground area. Fewer modules are needed for a given system size, helping lower racking and wiring costs.
Durable glass-glass design: Dual 2 mm glass layers enhance mechanical strength and long term weather resistance. The IP68 junction box and MC4 connectors support reliable performance even in harsh climates.
Stable long term performance: A total degradation rate of only 0.6 percent per year helps maintain output. Linear performance warranties assure 91.95 percent power at 12 years and 82.05 percent at 30 years.
Flexible system integration: A 1500 volt system rating and 25 amp series fuse allow long strings with reduced BOS costs. Compatibility with most modern string and central inverters is supported through standard electrical parameters.
This Waaree Bi-55-535 module converts sunlight into electricity using high efficiency monocrystalline PERC cells. Light strikes the front glass and passes to the 182 mm half cut cells, where photons are converted into DC power. The bifacial structure also captures reflected and diffuse light on the rear side, boosting total energy yield. The cells are wired as 144 half cut pieces to lower internal resistance and reduce power loss. Generated DC power flows through the IP68 junction box and MC4 connectors into the DC circuitry and inverter. The panel operates efficiently from cold to hot conditions due to carefully controlled temperature coefficients. System designers can use the 1500V rating to create long strings that feed compatible inverters, keeping energy harvest stable over decades.
Bifacial dual glass generation: The module uses tough glass on both sides instead of a backsheet. Front side glass receives direct sunlight, while the rear side collects reflected light from the ground or nearby surfaces. This dual side capture can significantly raise effective watt output under suitable site conditions.
Half-cut mono PERC cell architecture: Each 182 mm monocrystalline PERC cell is cut into two equal halves and arranged as 144 cells. This layout reduces current through each cell string, limiting resistive losses and improving efficiency. Half cut design also offers better shade tolerance compared to full cell layouts.
Thermal and electrical optimization: The Bi-55-535 is engineered with favorable thermal coefficients to help power stability. Power decreases by only -0.35 percent per degree Celsius, while current slightly rises with temperature. A nominal operating cell temperature of 43 degrees Celsius supports reliable output in hot environments.
