Our advanced panel solar bifacial represents a paradigm shift in photovoltaic technology. Unlike traditional monofacial modules that capture sunlight only from the front, this bifacial design harnesses reflected light (albedo) from the ground and surrounding surfaces, delivering up to 30% more energy generation per square meter. Engineered for high-durability and exceptional performance in diverse climates, this panel solar bifacial is the optimal solution for commercial rooftops, solar farms, and ground-mounted installations where maximizing return on investment (ROI) is critical.
Each module features a dual-glass construction with high-transparency tempered glass on both sides, paired with a robust aluminum frame. This design not only enhances light capture but also provides superior resistance to PID (Potential Induced Degradation), micro-cracks, and harsh environmental conditions such as salt mist and ammonia. Whether deployed over white gravel, snow, or a reflective rooftop surface, this panel solar bifacial consistently outperforms standard modules.

Q1: How much extra energy can I expect from a panel solar bifacial compared to a standard panel?
A: The gain depends heavily on the ground's reflectivity (albedo). On a white gravel roof (albedo 0.5), expect 15-20% more energy. On snow (albedo 0.8), gains can reach 30%. On grass or dark soil (albedo 0.2), gains are typically 5-10%.
Q2: Do I need special mounting or inverters for these bifacial modules?
A: No. Our panels use standard 1500V connectors and are compatible with all major string inverters and optimizers. However, we recommend using a reflective ground cover (e.g., white membrane or gravel) and mounting the modules at least 1 meter above the ground to maximize rear-side light capture.
Q3: Are bifacial panels more fragile than monofacial ones?
A: Actually, they are stronger. The dual-glass construction provides excellent mechanical strength. Our modules have passed hail impact tests (25mm ice ball at 23 m/s) and static loading tests up to 5400 Pa. The glass is heat-strengthened, not fully tempered, which reduces the risk of spontaneous breakage.
Q4: What is the warranty for this panel solar bifacial?
A: We offer a 12-year product warranty covering manufacturing defects and a 30-year linear power output warranty. The power warranty guarantees at least 98% of nominal power in year 1, with a maximum annual degradation of 0.40% thereafter, ensuring 87.4% output in year 30.
Q5: Can I install these panels vertically (e.g., on a fence or sound barrier)?
A: Yes! Vertical installation is a popular application for bifacial modules, especially in agrivoltaics or along highways. The vertical orientation captures morning and afternoon sun effectively and allows for easy cleaning by rain. Our frame is designed to handle the wind loads of vertical mounting.
Q6: How do I clean the rear side of the panel?
A: In most cases, natural rainfall is sufficient to keep both sides clean, especially if the panels are tilted at 10° or more. For dusty environments, periodic cleaning with deionized water and a soft brush is recommended. The self-cleaning coating on the front glass reduces soil adhesion.
Q7: What is the minimum order quantity (MOQ)?
A: For stock items, MOQ is 1 pallet (28 modules). For custom orders (e.g., specific cable length or connectors), MOQ is 1 MW (approximately 1,800 modules). We also offer sample orders for testing and certification.
