Model BBS24MC505 | Mono PERC | 132 Half-Cut Cells | Bifacial | 1500V System Voltage
The Bluebird Solar BBS24MC505 505W Mono PERC bifacial solar panel is designed for high efficiency rooftop and ground mounted systems. This advanced module combines monocrystalline half-cut cells with bifacial PERC technology to harvest more energy from both the front and rear sides. With a panel efficiency up to 20.46%, it delivers strong output even where space is limited on residential, commercial, or industrial sites. The module sits in a robust anodized aluminium frame with 3.2 mm tempered, anti reflection glass for long term durability. A 12 year product warranty and 30 year power warranty support long life performance and bankable returns for your solar investment. This panel is engineered and manufactured in India by Bluebird Solar Pvt. Ltd., a trusted brand with decades of experience in electrical and solar products.
High power density for limited roof space: The 505 W output and up to 20.46% efficiency enable more energy generation from smaller areas. This makes the module ideal for rooftops where every square meter counts.
Bifacial PERC technology for higher yields: Bifacial Mono PERC cells capture sunlight from the front and reflected light from the rear. This helps increase total energy production over the lifetime of the system.
Long term performance assurance: A 12 year product warranty covers material and workmanship defects. A 30 year power warranty limits degradation, helping the array deliver reliable energy for decades.
Robust construction for harsh climates: The panel uses 3.2 mm tempered, anti reflection coated glass and an anodized aluminium frame. This construction supports long life operation in diverse outdoor environments.
Optimised for utility, commercial, and rooftop systems: With a 1500 V system voltage rating and 25 A series fuse rating, the module fits modern string inverter architectures. It suits utility plants, C&I projects, and residential rooftops.
This Bluebird Solar BBS24MC505 Mono PERC bifacial solar panel converts sunlight into electricity using advanced monocrystalline half cut cells. Each of the 132 cells is precisely cut and interconnected to form a high performance circuit with lower internal resistance. When sunlight hits the panel surface, photons are absorbed in the Mono PERC cells and converted into direct current power. The bifacial design allows the rear side to capture reflected light from surfaces such as concrete, white roofs, or the ground, increasing total energy yield. The module operates reliably across a temperature range from minus forty degrees Celsius to eighty five degrees Celsius, with carefully engineered temperature coefficients that help stabilise performance in hot conditions. Generated DC power flows through the IP rated junction box into the system wiring, then to an inverter which converts it into AC power for on grid or off grid use.
Mono PERC half-cut cell conversion: High quality monocrystalline PERC cells capture sunlight and convert it into electrical energy efficiently. The half cut design reduces resistive losses and improves shade tolerance, which can increase real world production.
Bifacial rear-side energy gain: The panel uses a bifacial configuration so its rear side can also absorb reflected light. When installed above a reflective surface or with adequate ground clearance, this rear side gain can lift total kWh output over the year.
System integration and protection: Current and voltage produced by the module are controlled by the array design, series fuse rating, and maximum system voltage limit. The IP rated junction box, quality encapsulant, and tempered glass protect internal components, ensuring safe integration with compatible inverters and balance of system hardware.
