Junction Box-qc 091721-B (5A)

Small box, big solution! Though seems simple, it actually devotes to the profound understanding of the PV. The back button hardwired terminal holds the cable tightly to the most, and as it hides in the potting adhesive, which effectively avoids the risk of leakage caused by traditional crimping; The optimal designed potting area minimizes the cost; Low external and extensible form design can meet the demand of most thin-film modules. Approved by TUV and UL, and universally accepted. QC Solar, innovation everywhere!

Q: For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

Q: Solar products must be in the sun: Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)

Q: Product category and comparison of solar thermal utilization: Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.

Q: How to open solar stores: The solar industry is not mature, thousands of manufacturers, the winter "evaporation" summer prosperous seasonal manufacturers to consumers without security, therefore, with the help of the selected brand manufacturers force, forming and other brand segmentation is very important. In store layout, arranged according to the national unified you have chosen is specified by the manufacturer of the store template, establish the standard image of the store, which is beneficial to the consumers of your store "authentic" recognition, to "store security", according to the promotion plan provided by the manufacturer, with you in the local the promotional ideas store promotional site layout. Outside the store hanging promotional banners, the store posted eye-catching promotional posters, shopping guide to wear uniform clothing to consumers with a good visual image. Unified image of the terminal to do a good job, consumers will think that the product is reliable. Through training, so that the target customers to keep the root". Most of the customers entering the store is the target customers, to retain this part of the customer, to work hard on the training. In the terminal market, direct contact with the customer's shopping guide, shopping guide thrust plays a decisive role to a certain extent, in the solar energy marketing, customer and sales information is asymmetric, the customer can ask the seller about the solar energy many knowledge, if the sales sales ability is not strong enough, for the customer asked miss some of the main selling point, will sell in a passive state, natural products are unable to reach a deal, the good selling performance does not come out, it will be the loss of a large number of customers

Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.

Q: What are the third generation solar cells: The physical connotation contained in it is: should keep the advantages of the second generation thin film solar cell with low cost, and is much higher than the Shockley-Queisser limit (32.8%) high efficiency, stable and reliable performance and the battery and battery rich material sources. In other words, the so-called third generation solar cell is a kind of high efficiency, low cost, long life, non-toxic and high stability of the near ideal photovoltaic solar cells."

Q: 30MW solar thermal power plant total investment: The most expensive. Amorphous silicon solar cell conversion efficiency is the lowest, but the cheapest price, the most promising in the future will be used for general battery. Once a large area of the component photoelectric conversion efficiency of 10%, the price per watt power generation equipment down to $1 - $2, it is enough to compete with the current mode of power generation.

Q: Good solar polymer or monocrystalline: Spark solar energy products are also exported to many countries and regions such as Italy, Hongkong, Taiwan, the United States, Japan, Korea, Germany and other regions. After years of continuous development and improvement, not only to ensure good quality requirements, and won the domestic and foreign business partners to praise and affirmation. Stand on your point of view the factory must promise: fast delivery! Quality assurance! Price service is good. This season can undertake a large number of solar panels. This product can be customized for the price can also be agreed! Welcome to inquire or visit our company to discuss cooperation!

Q: What are the references of the solar automatic tracking system: Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply

Q: Solar energy product development prospects?: 2012-2016 China solar cell market analysis and Investment Research Report1 solar water heater industry faces new integration. Industry concentration is not high, at present the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. A line of enterprise and brand most high-end centralized development mode, to keep the solar intelligent and widely used will be closer, the solar water heater into the application of high-end, intelligent, integrated, brand enterprises lead the development direction of the industry's highest level and lead the industry, sales of high-end products less.
