How to match with purchase PV Junction Box

Purchase PV Junction Box,first of all concerned, we must establish a condition, no matter short-circuit current or just the maximum operating current, a component of the nominal data are in the standard test conditions, the values that the ambient temperature 25 ℃, the standard light intensity 1000W/m2, AM1.5 conditions, the test data.

But we must be clear that components send to different regions and different regions will produce changes in light intensity, such as Tibet, Ningxia and Xinjiang and other parts of part-time segment of the light intensity may reach 1700W/m2 so, then this time the battery pieces of current and voltage will change with changes in light intensity, I did the test in this regard, when the light intensity from 1000-1300W/m2, the current into a linear upward trend. So now most of the components for manufacturers in terms of no clear selection criteria, are likely to experience some selection criteria is the maximum operating current of 1.25 times, and some selection coefficient is 1.3, 1.4, but I think have no scientific basis.
