Chinese photovoltaic enterprises used to face many restrictions such as technical and trade barriers.
In 2010, the mass production of PANDA modules marked a crushing of monopoly of high-efficiency crystalline silicon technology from foreign photovoltaic companies. PANPA has become one of the three high efficiency cell technologies available for mass production and application, marking that Chinese photovoltaic enterprises began to compete in the global high-end photovoltaic market with efficient N-type mono-crystalline products.
Excellent power generation, excellent reliability and high cost performance: PANDA bifacial series modules, based on the state-of-the-art PANDA N-type monocrystalline silicon cell technology, feature good weak light and longer effective service life than conventional modules. Additionally, the bifacial power generation increases the power generation of modules by up to 30%.
The picture on the left shows the highest level (severity level 6) cyclic Salt Mist test for 1 cycle, simulating the state of the module frequently changing between "normally salt-filled environment" and "dry environment". One cycle test takes 7 days, 4 times IEC standard cycle test takes 32 cycles in total, plus other test items, the whole procedure takes 242 days.
After the test, the visual inspection found that there were no corrosion products on the frame and glass, and no defects (pinholes, bubbling or cracking, etc.) in the silicone and film. The IV test results showed that the degradation rates of each parameter of the module were low, the power degradation rate was only 1.9%.
