In order to further study the reasons for the poor power generation performance of multi-busbar modules in actual projects, the company also compared the power generation performance of 12BB single-sided modules and 18BB double-sided modules under various radiation intensities, whether it is 12BB modules or 18BB modules For components, the lower the irradiation intensity, the worse the power generation performance. For example, when the irradiation amount is 200~400W/m2, the power generation of the multi-busbar module is more than 3% lower than that of the conventional 5BB module under this radiation intensity.
It can be said that “practice leads to true knowledge”, and the data obtained from empirical experiments are the most convincing. To sum up, due to the poor low-light performance caused by the low series resistance of the multi-busbar module, its power generation performance in outdoor practical applications is poor, and the average power generation of the 5BB module is about 2% lower than that of the 5BB module.
This means that although the power of MBB modules increases by about 5 watts, it does not actually increase the power generation income, and the investment income is even lower than that of 5BB modules. MBB technology looks beautiful, but its practical application is not so good. The actual power generation capacity is doubtful, and its application value at the client end is not high. MBB technology is “beautiful if it is beautiful, but it is tasteless”. It is still too early to say what the so-called MBB outlet is!
