About this product

Product information from the supplier.

Engineered for high-efficiency energy conversion, our Half Cell Poly Solar PV Modules are designed to deliver consistent power output across diverse environmental conditions. By utilizing an advanced SB 5BB design, these modules significantly reduce cell series resistance and stress between interconnectors, ensuring superior conversion efficiency and long-term stability for residential and commercial solar systems.

With a maximum power output of 330W and a verified module efficiency of up to 17.5% by TUV Rheinland, these polycrystalline panels are optimized for performance. Featuring anti-reflective and anti-soiling surface treatments, our modules minimize power loss from dust and debris, while the integrated bypass diodes provide critical protection against array shading, making them a reliable choice for maximizing ROI in photovoltaic installations.

Frequently Asked Questions

Q: What are the benefits of Half Cell technology in these solar panels?

Half cell technology reduces current flow and internal resistance, which lowers heat buildup and improves efficiency. It also allows the panel to continue producing power even when partially shaded.

Q: How does the anti-soiling surface improve energy production?

The anti-soiling coating prevents dust and dirt from adhering to the glass surface. This ensures that maximum sunlight reaches the cells, reducing the frequency of cleaning and preventing power loss.

Q: Can these modules withstand extreme weather conditions?

Yes, these modules are certified to withstand heavy mechanical loads, including wind loads up to 2400Pa and snow loads up to 5400Pa, ensuring structural integrity in harsh climates.

Q: What is the purpose of the EL double-inspection?

Electroluminescence (EL) inspection acts like an X-ray for solar cells, identifying micro-cracks or defects invisible to the naked eye. Double inspection ensures 100% defect-free delivery.

Q: Is this polycrystalline module suitable for low-light areas?

Absolutely. These modules are specifically engineered for outstanding performance in low-light irradiance environments, making them ideal for regions with frequent cloud cover.

Q: What does "Positive Power Tolerance" mean for this product?

A positive power tolerance of 0+3% means the actual power output of the module will be equal to or greater than the rated 330W, but never less, guaranteeing the specified performance.
