September 9th to 10th, DAH Solar was invited to attend the 4th China International PV Industry Summit Forum 2021, exhibiting our patented product Full-Screen PV Module and innovated product Low-Current PV Module.

Both products rely on the innovative technical processes, the excellent power generation gain and practical value have been unanimously recognized by the industry experts, as well as the high praise of  many professional media chanel in PV industry.

What is Full-Screen PV Module

What are the core advantages of Full-Screen PV Module compared to Normal PV Module?

No water, No dirt left on the Surface, Full Screen PV Module is capable to decrease power generation loss.The modules are operated outdoors all year round. Due to the height difference between the frame and the glass, the rainwater cannot be drained out of the normal modules. In rainy and snowy weather, or in areas with heavy dust, the modules are prone to water and dust accumulation, especially at the bottom of the module, which affects the power generation of the entire module. For full-screen module there is no height difference between the frame and the glass, No water No dirt left on the Surface and it Design Strong Self-cleaning Ability, Effectively reduce power generation loss, as well as manual cleaning frequency and operation and maintenance costs.

How much does water and dirt affect the power generation of normal modules?

The average power generation loss is over 6%. Research by professional institutions has shown that among the various factors that affect power generation, module dirt and shadowing account for 25%, which is also confirmed by outdoor filed comparison experiment between full-screen and normal modules. The test data of past year shows that, without manual cleaning and only natural washing by rain, the average power generation of the 182 full-screen module with the same battery and version is 6.15% higher than that of the 182 normal module.，in some days even higher than 9.62%. With time, due to the continuous accumulation of dust, the difference in power generation between the full screen and the normal modules will gradually increase.

The front of the module is all glass, how reliable is it?

No difference from normal modules. The full-screen PV modules adopts a unique and innovative structural design to make it have the same reliability as normal modules. This is also one of the core technologies of the full-screen PV module patent. According to the TÜV laboratory’s tests of damp and heat, high and low temperature cycle, mechanical load, and combined rigorous, the full-screen PV module has excellent waterproof performance (IP68) and mechanical load performance (5400Pa on the front and 2400Pa on the back). In addition, according to the climate characteristics of different regions in the outdoor demonstration test, the full-screen module can increase the power generation by more than 6.15% compared with the normal module, and won the "TÜV North German Outdoor Demonstration Quality and Effect Award".

How wide is the application of the full-screen patent? Has it been mass-produced?

Full screen technology can be applied to 99% of the modules on the market.(Except for some customized components such as frameless or BIPV).The core technology of the full-screen PV module lies in the innovative structural design and manufacturing process. At the beginning of the design, the compatibility with the mainstream modules on the market has been considered. Therefore, as long as the full-screen patented technology and process of DAH Solar is adopted, it is enough to apply the full screen technology to modules of various layouts and sizes.

The production line has been upgraded in June of this year. Full-screen modules are currently in mass production, and all production indicators have reached the level of conventional modules, By now over 100 megawatts worldwide have been placed.

In this summit forum, DAH Solar not only exhibited full-screen modules, but also brought innovative products-low-current modules. As the name suggests, the main feature of low-current modules is their lower operating current, as well as module power and power generation gains brought by low current.

10W higher of single module.The three-cut process effectively reduces the resistance loss, has more cell gaps and higher reflection efficiency, resulting in higher module power. Compared with half-cell modules, the power of a single module can be increased by 10W. Therefore, with the same installation area, the installation capacity of low-current modules is 1.82% higher than that of normal half-cell modules.

1.5% increase of power output per watt . At present, the working current of normal 182 modules is above 13A, while the working current of low-current modules is only 8.41A~8.83A, with lower working current and lower power loss, the power generation can be increased by more than 1.5% while reducing risk of hot spots.

Higher system compatibility. Low-current modules can not only achieve module power and yield, but also can be well matched with existing inverters and systems, especially for photovoltaic systems below 20KW, which will effectively reduce system costs and electricity costs.

Innovation leads development, craftsman creates the future! As one of the top 100 photovoltaic brands in China,we always believe that DAH Solar will surely be able to move towards a brighter future in the development of new photovoltaic energy, continue to bring better innovative products to the industry, continue to create higher value for users. Finally to be a benchmark in the photovoltaic subdivision field!

New productsNew products ''Full-Screen'' PV module 430-460w and 182cells three cut Low-current pv module 520-560w mono In addition DAH innovative product SolarUnit Smart PV System 920-1100w are on sale.
