High-efficiency 550 Wp Mono PERC Bifacial solar panel with rear-side power gain, durable build, and excellent low-light performance; Ideal for rooftops, homes, and commercial setups.
Okaya’s Mono PERC Bifacial Solar Panels combine high-efficiency PERC cell design with the added advantage of rear-side power generation. Engineered for Indian conditions, they deliver up to 21.3% efficiency with consistent performance even in low-light environments. Designed with MBB half-cut cells and durable EVA encapsulation, this 550Wp solar panel is ideal for residential rooftops, industrial buildings, and commercial solar farms.
A bifacial solar panel captures sunlight from both its front and rear surfaces. While the front side absorbs direct sunlight, the rear side generates additional electricity by utilizing light reflected from the roof, ground, or nearby surfaces. The amount of extra energy produced depends on factors such as mounting height, ground reflectivity (albedo), and installation design, but bifacial technology generally delivers better overall energy generation than a comparable single-sided panel.
A typical 3kW solar system requires approximately 6 panels of 550Wp each (3,000W ÷ 550Wp, rounded up). The final number may vary depending on roof orientation, shading, available installation space, and inverter sizing, so it is advisable to confirm the exact system design with your solar installer before purchase.
This panel is suitable for both residential and commercial installations. Its 550Wp output, advanced half-cut Multi Busbar (MBB) cell technology, and durable construction make it equally suitable for residential rooftops, commercial buildings, industrial facilities, and utility-scale solar projects.
Partial shading affects all solar panels, but this model's half-cut Multi Busbar (MBB) cell design improves shade tolerance and reduces electrical losses compared to traditional full-cell panels. As a result, shading over a small portion of the panel has a lower impact on overall power generation, helping maintain better performance in real-world rooftop conditions.
This is the non-DCR version of the panel and is intended for standard private residential and commercial installations. If your project requires eligibility under government programs such as the PM Surya Ghar Yojana, you should choose the Okaya OP144MHB550W-DCR model, which complies with Domestic Content Requirement (DCR) guidelines. The non-DCR version is not intended for subsidy-linked DCR applications.
The two warranties cover different aspects of the panel. The 12-year product warranty protects against manufacturing defects and workmanship issues, while the 30-year performance warranty guarantees that the panel will continue to generate electricity at or above a specified minimum output level throughout its service life. Together, these warranties provide both product reliability and long-term performance assurance.
