How Tanfon solar panel efficiency ? The test will tell you the truth

Today we visited a local customer in Zimbabwe and saw that his showroom had solar panels purchased from us as well as solar panels purchased locally. Then we moved the two solar panels out under the sun to test the difference. What's the difference? Our test video will tell you the truth:

 

Zimbabwe solar panel testing

The sunshine is very good today. At 2:45PM in the afternoon, the sun is shining in the sky. We use a multimeter to connect the port of the solar panel to test the current and voltage. After testing, the voltage of our Tanfon solar panel is 34.9V, the current is 14.6A, P=UI, so the power is 509W, actual power of this solar panel is 450W. This shows that when the sunlight is good, our solar panels produce more electricity than the actual power.

We used the same method to test the solar panels purchased by other suppliers locally. After testing, the voltage was 35.2v, the current was 7 A, and the power was only 246.4W. However, the power of this solar nameplate is 350W. Under good sunshine conditions, the test result is only 246W, which is lower than the marked power, more than 100 watts lower.

So you get what you pay for. Our solar panels are guaranteed to have sufficient power and high power generation efficiency for you! we use the N-type TOPCON half cell solar panel, the panel cell brand is LONGi, it is the top brand in the solar. Make sure the best quality for you ,We have professional EL testing equipment,EL testing is a very important test, which can avoid or control the occurrence of cracks in finished products. If cracks exist, the life of the battery panel will be affected;btw,we use P-type crystalline silicon wafers and N-type crystalline silicon wafers have different power generation efficiencies.Why is the power generation efficiency of N-type crystalline silicon wafers higher than that of P-type?


Because their grid lines are different
P-type crystalline silicon wafer gate lines: 9-11 gate lines
N-type crystalline silicon wafer gate lines: 16-18 gate lines

So Tanfon solar panel is the TOP solar panel !
