PV solar panel(module) from silicon wafer

Normally PV solar cell can be classify two kind according to substrate of PV solar cell
first is silicon crystalline base PV cell second is non silicon crystalline PV cell
silicon crystalline base PV cell cell one more classify two kind mono crystalline or multi crystalline mono crystalline wafer is make from mono crystalline ingot by slice












multi crystalline wafer is make from multi crystalline ingot by slice

you can see what is difference on surface between mono & multi
this mono or multi crystalline silicon wafer is use for substrate for PV solar cell by screen printing and other extra process










this mono or multi PV solar cell use for mono or poly(multi) PV panel (module) normally 156x156mm, 6x9= 54 solar cell using for 200watt panel

China to cut 15% of PV solar FiT subsidy by 2018

The Chinese government's National Development and Reform Commission (NDRC) says it will reduce its PV solar FiT subsidy by about 15% in 2018 China is divided into three regions according to the solar resources, and in the case of large-scale solar power plants, the subsidies according to the regions no 1 area is CNY0.55/Kw(USD 0.0825), no 2 area is CNY0.65/Kw(USD 0.0975) & no 3 area is CNY 0.75/Kw(USD 0.1125) Rural solar FiT subsidies, which aim to offset the income disparity between urban and rural areas, will maintain CNY0.42/Kw same as this year By the third quarter of this year, the PV solar plant installed in China will be about 43 Gwh, which will reach 54Gwh by the end of the year this is an increase of nearly 50% compared to the installation of 34.5Gwh solar power plant in 2016 The total cumulative facility capacity is expected to reach 77.8 Gwh by 2016, and 132.3 Gwh by adding 54 Gwh in 2017 The new subsidy rate announced this time will apply from Januar
