Import 300 Watt Solar Panel — Buy in wholesale FOB from Supplier in China

Yangtze Solar Power Co., Ltd. offers a 300W monocrystalline solar panel designed for residential and utility applications, featuring a positive power tolerance of 0 to +3%. The panel integrates 72 monocrystalline cells, each measuring 156x156 mm, and achieves a module efficiency of 15.54%. It is rated for wind loads up to 2400 Pa and snow loads up to 5400 Pa, with additional resistance to salt mist, ammonia, and blown sand, making it suitable for coastal, agricultural, and desert environments.

Monocrystalline panels like this one are known for their higher efficiency and better performance in low-light conditions compared to polycrystalline alternatives. The cells are encapsulated in 3.2 mm high-transmission, low-iron tempered glass, a standard configuration for maximizing light absorption while maintaining durability. The panel undergoes 100% EL double inspection to ensure defect-free modules, reducing the risk of hot-spot heating and early degradation.

This panel is ideal for off-grid systems, residential rooftops, or utility-scale projects where space efficiency is a priority. The electrical parameters include a maximum power voltage (Vmp) of 36.2V and a maximum power current (Imp) of 8.35A, with an open-circuit voltage (Voc) of 45.2V and a short-circuit current (Isc) of 8.77A. Buyers should confirm these values align with their inverter specifications. Originating from Hefei, Anhui, the panels are certified by TUV, CE, and UL, providing assurance of compliance with international safety and performance standards.

Yangtze Solar Power Co., Ltd. is based in Hefei, Anhui Province, China, with its registered address at No.72 Shufeng Road, Shushan District. The company specializes in monocrystalline solar panels for residential, commercial, and utility applications, with a focus on durability in harsh environments. Its harbor-tier verification status confirms a documented business presence, though specific production capacities or export histories are not disclosed in the profile.

The supplier provides a 10-year product warranty and a 25-year linear power output warranty, which are standard for quality solar panels. While the profile mentions certifications from TUV, CE, and UL, buyers should request copies of these certificates to verify their authenticity and applicability to the specific panel model. As with any new supplier, conducting a factory audit or requesting references from existing clients can provide additional confidence in the product’s quality and reliability.
