Most of distributed roof PV station will use 166 solar panel

166mm solar cell will become the main specification for the solar modules.

166mm solar cell rapidly occupy the distributed market with their advantages of flexibility, lightness, high efficiency, full load and stable income. At present, they have become the mainstream of module selection in the distributed field. The reasons are following:

1、 The large-size solar module of large silicon wafers are of high value in ground power plants

 Large solar module can save costs. 1)If we can be supported by terrain conditions , the increase of support size apportions the single cost of support and foundation. 2)The cost of cable and inverter is saved; 3)The labor cost is saved.

2、 Advantages of 166 photovoltaic modules in roof distributed power plants

Different from the logic of the ground power station, the roof distributed power station needs to be covered with the roof as much as possible, and one person can move it. 

In addition, the working current of 166 module is lower than 11a, which can widely match distributed inverters, power optimizers and micro Inverters from different manufacturers and power segments around the world. There are many inverter models in roof distributed projects, and the certification and power grid access standards in different countries are different. Therefore, the time cycle and cost required to comprehensively improve the current are very high. It is difficult for large silicon chipsolar module to challenge the  position of 166 sollar cell in the household market.

3、 The advantages of 166 photovoltaic modules in industrial and commercial distributed projects

Small businesses are similar to residential roofs. For large-scale industrial and commercial application scenarios, a large number of solar module are usually arranged in pieces (leaving a certain maintenance channel space), rather than carrying two strings of solar module with a single support like the ground power station, and there is no need for pile foundation, and the amount of support metal is low. Therefore, the BOS cost savings brought by large solar module are significantly reduced, mainly due to slight labor cost savings. As in the consumer market, improving component efficiency to increase the total installed capacity is the most important. In addition, 166 assembly has better load capacity under the installation form of four point installation.

If the roof is flat and easy to handle, large businesses can also use 182solar module with high efficiency.

In the future, 182 solar module will be used in ground power stations, and 166 solar module will be used in household and industrial and commercial roof power stations.
