- Q: What is the difference between photovoltaic products and solar energy?
- At the same time, the solar photovoltaic power generation system, which is centralized, such as large northwest ground photovoltaic power system; one is distributed (divided by >6MW), such as building roof photovoltaic power generation system of industrial and commercial enterprises, residential roof photovoltaic power generation system.Solar photovoltaic effect, referred to as photovoltaic (PV), also known as the photovoltaic effect (Photovoltaic), refers to the uneven illumination of semiconductor or semiconductor and metal parts of the potential difference between the phenomenon of.Photovoltaic is defined as the direct conversion of ray energy. In the practical application, it usually refers to the conversion of solar energy to electric energy. Its implementation is mainly through the use of silicon and other semiconductor materials made of solar panels, the use of light to generate direct current, such as our daily lives can be seen everywhere in the solar cell.
- Q: Solar garden lamp product parameters
- * main body material: the lamp post is full steel structure, whole hot galvanizing / plastic spray treatment* solar modules: crystalline silicon 15-80WP (by load configuration)* operating voltage: DC 12V - 24V* controller: solar lamp controller, light control + time control
- 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: What is the future of solar power
- Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.
- Q: Now there is no sun, cloudy days can use solar products?
- In addition, if you are a household, engage in electric heating can be complementary to each other!
- Q: 30MW solar thermal power plant total investment
- At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price
- Q: Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery
- On the direct use of solar energy in humans is still at the primary stage, mainly solar collectors, solar water heating systems, solar heating, solar power, solar wireless monitoring etc.. Along with the development of modern enterprise system in our country's popularization and deepening development of enterprise informatization construction unceasingly thorough, safety and prevention work for enterprises using digital video technology has been combined with the development of solar energy technology represent the general trend, the launch of the real Winncam zero wiring for wireless monitoring solution. (solar wireless monitoring installation renderings)In the modern industrial park, the implementation of video surveillance system, the security department can realize all-weather real-time video monitoring in the industrial park at the entrance, the main road, office buildings, such as perimeter wall sites; the relevant departments can understand the situation, strengthen campus security management, improve work efficiency; the relevant departments can real-time understanding of each monitoring point the leading enterprises in the office; using a desktop computer, you can keep abreast of the real-time status of each monitoring point, handling emergencies, can also record multiple days ago, tracking and analysis, in addition to the establishment of local network monitoring system, but also to focus on remote video monitoring of branches. The actual production of Zhongcheng labor discipline inspection at any time Trw Corporation employees according to the actual needs of the park, some difficulties to take power, we use Solar power supply, with reference to the relevant international standards and national standards, combined with the company's experience in the Industrial Park monitoring and accumulated, the preparation of this zero wiring solar wireless monitoring technology program.
- 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: Advantages and functions of solar energy
- The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance
- Q: What are the current domestic solar energy products, which practical
- The advantages of solar water heaters and photovoltaic power generation are once and for all, slowly after many years of use can see the advantages of saving electricity bills, but the disadvantage is instability, a lot depends on the intensity of light.
