Model Bi-55-540 | P-Type Mono PERC | 144 Half-Cut Cells | Bifacial | 1500V System Voltage
The Waaree Bi-55-540 540W PERC bifacial monocrystalline solar panel is engineered for high performance on commercial and utility projects. Its advanced dual glass construction and bifacial design deliver excellent energy yields on rooftops, carports, and ground mount systems. A robust 144 half-cut cell layout improves shade tolerance and reduces resistive loss under real world conditions. With up to 20.98% front side efficiency, this module helps maximize power density where roof or land area is limited. The Bi-55-540 panel is built around reliable P-Type mono PERC technology and designed to lower the levelized cost of energy over its long lifetime. It suits both grid-tied arrays and appropriately designed off-grid systems using compatible inverters and charge controllers. Made by Waaree Energies in India, the module combines durable materials, optimized thermal coefficients, and a strong multi decade performance warranty.
High 540W output per module: Each panel delivers up to 540 W at Standard Test Conditions, which increases system power while reducing the number of modules required. This allows faster installation and lower balance of system costs across many project types.
Bifacial energy gain potential: The framed dual glass design harvests light from both the front and rear sides. Under suitable mounting, backside reflection can significantly boost total energy output compared with monofacial modules.
Efficient PERC monocrystalline cells: 182 mm mono PERC cells and half cut architecture raise efficiency up to 20.98% on the front side. This design reduces resistive losses and helps the module perform better under high irradiance and hot conditions.
Durable dual glass construction: Front and rear 2 mm glass layers improve mechanical strength and long term reliability. The IP68 junction box and quality encapsulation help protect the cells from moisture, dust, and harsh outdoor environments.
Long term performance assurance: A 12 year product warranty is combined with a linear power warranty. Output is warranted at 91.95% after 12 years and 82.05% after 30 years, which supports long term investment planning for solar assets.
This Waaree bifacial solar panel converts sunlight into usable DC electricity through high efficiency mono PERC cells. Light falling on the front glass is absorbed by the 182 mm cells, generating current at a maximum power voltage of around 41.75 volts. Additional light is captured by the rear glass when reflected off the ground or nearby surfaces, which increases total energy generation. The 144 half cut cell configuration reduces resistive loss, improves shade tolerance, and enhances energy harvest throughout the day. Electrical output flows through an IP68 junction box and MC4 compatible connectors to inverters or charge controllers. System designers can connect the module into strings up to 1500 V system voltage to match modern commercial and utility scale equipment.
Front side energy conversion: Direct sunlight hits the front glass and passes into the monocrystalline PERC cells. These cells generate DC power with a rated maximum of 540 W at Standard Test Conditions. Under typical operation, the panel runs near its maximum power point of 41.75 V and 12.95 A, where energy conversion is most efficient.
Rear side bifacial gain: The transparent rear glass lets the module capture reflected and diffuse light from behind the panel. When mounted over bright surfaces, the rear side can add significant extra wattage to the nameplate rating. This bifacial effect helps raise kWh production without expanding the array footprint.
Thermal and electrical stability: The module operates within an ambient range of -40 to 85 °C. Its power temperature coefficient of -0.35 % per °C limits output loss in high heat. A voltage coefficient of -0.27 % per °C and current coefficient of 0.05 % per °C support stable performance across changing weather conditions.
