Newly released M6 Silicon Wafers
The upgrade of M6 silicon wafer’s specification allows a larger light-capture area which increases the power of cells and modules while reducing the manufacturing cost per watt. After extensive evaluation, M6 is considered to be the optimal size of the new generation of silicon wafers.
On May 24, LONGi first announced the its price of M6 monocrystalline silicon wafers - at 3.47 yuan/piece. At a cost-per-watt comparison, M6 is equivalent to M2 and increases the output power by 8.8% vs M2. With M6, procurement cost of silicon wafers is reduced by 4% /watt.
LONGi’s existing crystal pulling and slicing are compatible with M6 which ensure the mass production and supply of M6 silicon wafers in 2019. The company' s scale of production is expected to reduce the price premium of M6 vs M2 silicon wafers to less than 0.2 yuan.
Next Generation M6 solar cell encapsulated modules
With M6 mono crystalline wafers, solar modules configured with 72 cells can achieve 430W. Compared with conventional polycrystalline power station systems, the BOS cost using 430W bifacial modules is 0.21 yuan/watt. Coupled with 10% more power generation and average annual degradation of less than 0.45%, the value advantages can reach 0.8 yuan /Watt more, significantly reducing the cost of electricity.
Experts in the photovoltaic industry have given unanimous affirmations and recognitions to the new products. Wang Bohua, secretary-general of China PV Industry Association, said: "PV enterprises should continue to innovate product technology to enhance the value of PV investment and promote the rapid decline of electricity costs. LONGi bring new breakthroughs to the development of the industry which is highly valuable for reference and promotion."
