ExTEL Solar Dust Detection System is a good helper for maintenance and operation
Checking the amount of dust falling on the module is the most direct basis for determining when to wash away dust and dirt from the module. ExTEL Energy has developed a solar dust detection system (DAS 2.0), which contains 2 small modules. The exposed module is an indicator of the cleanliness of the case site. The other module is covered and not exposed for a long time to prevent it from being affected by environmental dust. clean mod.
Chen Jinxiong, general manager of ExTEL, said that DAS 2.0 opens the lid regularly every day and compares the cleanliness of the two modules. The internal computer will automatically calculate the amount of dust, and the mobile phone can receive the message remotely to determine the timing of cleaning. Chen Jinxiong said that in order to maintain the continuous and effective power generation of the solar system, maintenance and operation is very important. Regular cleaning is mostly adopted. However, cleaning the modules is not only time-consuming, but also difficult to determine the timing. Too many times or not enough times are not a good idea, and it affects the cost or power generation. Income cannot be based solely on rules of thumb.
Since the launch of DAS 2.0, it has been recognized by the market as the best helper for maintenance and operation. If the amount of dust detected by DAS 2.0 does not reach the level that requires cleaning, it can be postponed or canceled. The annual savings will exceed the investment cost of the equipment. On the contrary, if cleaning is neglected, DAS2.0 will also show reduced power generation and loss of electricity revenue, giving investors a deeper sense of "pain" with specific data.
ExTEL launches a leasing plan to increase the popularity of DAS2.0 at an affordable price. Chen Jinxiong emphasized that the company has expertise in detection and analysis technology and equipment, and is a partner of EPC and professional maintenance companies, forming a complementary and business division of labor rather than competition. It also serves project investors and owners.
