7. Q: Do you have solar project engineer who can guide me to install system?

A: Yes, we have a professional engineer team. They can teach you how to install a solar system.

Q: What is the typical lifespan of a solar silicon wafer?: The typical lifespan of a solar silicon wafer can vary depending on various factors such as the quality of the wafer, manufacturing process, and operating conditions. However, in general, a well-maintained and properly installed silicon wafer used in solar panels can have a lifespan of 25 to 30 years or even longer.

Q: Ultrasonic cleaning cleaning silicon?: Yes, but it is said to be the frequency of the 1MHz cleaning machine. Is not an ordinary low-frequency 100K below the frequency of cleaning machine.

Q: In the silicon surface cleaning, there is a final step, the silicon chip into the 4% concentration of HF solution soak for five minutes, to hydrogen passivation treatment, and then rinse with deionized water after nitrogen drying,What is the role and mechanism of this hydrogen passivation?: Wire cut damage layer thickness of 10 microns.Generally use 20% alkali solution in the corrosion condition at 90 C

Q: Solar silicon wafer cutting fluid content is polyethylene glycol, flash point 182-278 DEG C, saturated vapor pressure of 6.21KPa/20 C / C in storage in the barrel, after exposure, its volatile gas is harmful?: 2, the glass can not be used as the bearing plate of the crystal rod, if the use of graphite plate, grinding down the silicon powder containing a certain amount of graphite, it is difficult to deal with the recovery of silica fume3, can only be used for single crystal cutting4, the cost of the problem, and now the price of diamond wire fell faster, diamond wire cutting costs should be close to the cost of cutting free abrasive

Q: What are the different materials used for encapsulants in solar silicon wafers?: The different materials used for encapsulants in solar silicon wafers include ethylene-vinyl acetate (EVA), polyvinyl butyral (PVB), and thermoplastic polyurethane (TPU).

Q: How are solar silicon wafers protected from electrical surges?: Solar silicon wafers are protected from electrical surges through the use of protective devices such as surge arresters or varistors. These devices are connected in parallel with the solar cells and act as voltage clamps, diverting excess electrical energy away from the wafers. This helps prevent damage to the delicate silicon material and ensures the longevity and reliability of the solar panels.

Q: Can solar silicon wafers be used in solar-powered electric vehicles?: Yes, solar silicon wafers can be used in solar-powered electric vehicles. These wafers are typically used in photovoltaic (PV) solar panels to convert sunlight into electricity. By integrating solar panels made of silicon wafers onto the surface of a solar-powered electric vehicle, it can generate electricity from the sun and contribute to powering the vehicle. However, the efficiency and power output of the solar panels depend on various factors such as the size of the panels, the quality of the silicon wafers, and the amount of sunlight available.

Q: How does the efficiency of a solar silicon wafer change with cloud cover?: The efficiency of a solar silicon wafer decreases with an increase in cloud cover.

Q: What is the role of solar silicon wafers in reducing the digital divide?: Solar silicon wafers play a crucial role in reducing the digital divide by facilitating the production of affordable and sustainable solar panels. These panels can be used to generate electricity in remote and underserved areas where access to the power grid is limited. By harnessing solar energy, these communities can power devices such as computers, smartphones, and other digital technologies, thus bridging the gap in access to information and communication. Solar silicon wafers enable the production of cost-effective solar panels, expanding the reach of clean and renewable energy solutions, and contributing to narrowing the digital divide.

Q: What is the impact of impurity concentration on solar silicon wafers?: The impurity concentration in solar silicon wafers has a significant impact on their efficiency and performance. Higher impurity concentrations can lead to reduced solar cell performance, lower conversion efficiency, and decreased overall power output. Impurities, such as iron, can act as recombination centers and hinder the flow of electrons, affecting the charge transport properties of the solar cell. Hence, minimizing impurity concentrations is crucial for achieving optimal solar panel performance.
