Solar Module Water Quality Testing
   
 

In recent years, with the promotion of floating solar farms, some aquaculture and plantation operators have concerns about the installation of silicon-based modules for power generation.

 

To eliminate the public's concerns about the environmental impact of solar power generation, TSEC commissioned relevant experiments to prove it.


Mainly focused on two areas:

 

(1) Whether soaking modules in water will cause performance degradation

To clarify whether soaking modules in water will cause performance damage, a third-party independent agency was commissioned to conduct IPx8 experiments. That is, immerse the module in 5% salt water, with a depth of 1 meter, to simulate the experiment of the module in sea water, and observe no significant difference in electricity performance.

 

 

(2) Whether immersing modules in water will affect water quality

 

TSEC provided supporting modules for water immersion tests, and the water quality was outsourced to an environmental protection agency-approved laboratory for sampling and testing.

 

The first group of experiments simulates the situation where the solar panel in the solar farm is blown down by a typhoon. Assuming that the modules are undamaged, they are immersed in water for more than 7 days to see if the water quality is affected, and an environmental testing agency approved by the Environmental Protection Agency is commissioned to assist us in taking water quality samples from the solar modules immersed for more than 7 days and to conduct toxic substance testing.

 

According to the test results, a total of 25 items, including 8 heavy metals (arsenic, mercury, cadmium...) and general metals and volatile organic compounds (VOCs), were far below the Environmental Protection Agency's drinking water standards .

 

The other set of experimental conditions simulates the scenario where the module is shattered by an object and dropped into the water for more than 7 days. Therefore, the module is deliberately damaged and immersed in water for more than 7 days, and the same testing agency is commissioned to take sample and test, and it is also found that the test results for the 8 heavy metals (arsenic, mercury, cadmium...) and general metals and volatile organic compounds (VOCs)......, are far below the Environmental Protection Agency's drinking water standards.

 

 

To verify the reproducibility of water quality testing experiments, TSEC commissioned an outsourced test from another Environmental Protection Agency-approved laboratory that could assist us with immersion testing units, whether immersed or shattered modules, for their impact on water quality.

 

The laboratory feedback data indicates that the test values are also far below the Environmental Protection Agency's drinking water standards . This indicates that solar modules produced by our company will not affect water quality after soaking in water for several days and meet the drinking water standards set by the Environmental Protection Agency.

 

 

TSEC actively cooperates with government policies and conducts various tests to eliminate the public's concerns and provide more peace of mind while ensuring power generation efficiency.

   
   
TSEC modules pass strict TÜV Rheinland dual-85 PID test for 1000 hours
   
 

 TSEC modules pass strict PID testing up to 1,000 hours according to Germany's Rhine Dual 85 standard.

       

       

 

TSEC modules adopt TSEC high-quality anti-PID solar cell/packaging material
* Improve quality: improve the characteristic of the ARC layer to improve the quality of the cells
 

Improve the PID effect: the PID (Potential Induced Degradation) effect means that after the cells constitute a solar module or power plant, the potential difference formed by these cell damages the solar cell or module (Leakage path), and then which further results in the decrease of the power generation performance of the cells.
On the contrary, the feature of the product is to improve the characteristics of the ARC layer (SI-rich), which can effectively improve the anti-PID effect and improve the quality of the cells.

 

* Increase efficiency: repair surface danglingbonds to better the efficiency of cells
 

The danglingbond on the surface of the wafer is just the electron which has yet to form the bonding. The danglingbond has high activity, which tends to form the trap centers and then results in the reconnection of the electron/hole pair. Accordingly, the life of the carriers will be reduced, so the conversion rate will be decreased.
The feature of the product is to repair the surface danglingbonds by annealing to improve the efficiency of the products.

 

TSEC adopts 3–stage EL test
* Example of EL inspection result
 

 

The so-called EL inspection is to use the EL (Electroluminescence) phenomenon to perform the inspection, which makes the current flows through the cell and then uses special camera to check whether there is microrack or poor electrode or other defects which cannot be identified by naked eye inside the cell via the light-emitting characteristic of the cell.

The defect or impurity of the cell may show different color in the image, which can be used to check the quality.

 

Cell Product Features
*

TSEC's solar cell products are all PID-free, which can pass PID testing for 1,000hrs (test conditions: -1,000V, temperature: 85℃, humidity: 85%).

* TSEC's solar cell products have been highly praised by global customers for their high quality, high efficiency, high stability, and reliability.

 

 

 

In addition to inheriting all the advantages of E-Cell, V-Cell solar cell products have been successfully developed with high conversion efficiency through advanced processes and the introduction of new materials, and can be mass-produced using existing equipment. The V-Cell process can further reduce the back surface composite carrier velocity (SRV[cm/s]) to increase the open-circuit voltage (Voc) and improve the back reflection rate, thus increasing the short-circuit current (Isc).

 


Product Advantages
* High parallel resistance: After performance testing, parallel resistance values above the screening standard are selected to maintain high output efficiency in low-light environments.
* Low reverse leakage current: Can reduce the risk of hot spots, improve long-term operation quality, and provide protection in shaded operations.
* Low breakage rate: TSEC solar cells attach great importance to the manufacturing process, such as supplier selection, monitoring, and documentation, in order to achieve the goal of low breakage rate and high production rate for high-quality solar cells.
* Uniform appearance color: The solar cells are classified according to their shade and each category has uniform appearance.
* Good weldability: Good conductive materials make busbar electrodes easy to weld.
* PID-free solar cell product: TSEC adopts the most frequently used method to set up the PID test and acceptance standard for single assembled cell; after optimized parameter adjustment, the solar cell can have good resistance against the PID test.  All of TSEC cell products are PID-free products, which have passed the PID test for 1,000hrs (-1000V, Temperature: 85℃, Moisture: 85%).
