Panel Overview and Specifications

The Shark 440 bifacial solar panel boasts impressive power generation capabilities, ranging from 440 to 530 watts. Its substantial size, approximately 7 feet tall, makes it a significant addition to any rooftop. This single panel is claimed to be sufficient for powering a typical Indian household.

The panel's dimensions are substantial, measuring approximately 6.9 inches in height and 3.4 inches in width. Its half-cut cell technology enhances efficiency and mitigates the impact of shading. The panel is remarkably large considering its high power output.

Half-Cut Cell Technology and Efficiency

The Shark 440 utilizes half-cut cell technology, where each cell is divided into two, reducing resistance and improving performance. This design significantly minimizes power loss from shading, a common issue with traditional solar panels.

Even when placed on its back, the panel demonstrates a considerable voltage output (around 42 volts). This is due to its bifacial design capturing light from both sides, demonstrating its advantage over standard panels.

Installation and System Requirements

Installation requires a solar inverter, but a solar charge controller is necessary when connecting to a battery system. High voltage from the panels requires a charge controller to regulate the voltage and prevent damage to the battery.
