Q: How to make solar energy?: Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.

Q: What are the disadvantages of traditional solar water heater: Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.

Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.: Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.

Q: How to do a good job of solar water heater marketing?: Three, safety: non pressurized solar water heater working principle. Gas water heaters, electric water heater is widely used in the existing safety problems, the province each year due to the accident, use water heater to cause death in 5 cases above, and with the increase of users, the number is rising, the use of solar energy does not exist poisoning and the hidden danger of electric shock, very safe, even if the solar water heater electric heating function, because the heating body away from the user, coupled with the use of time is only 1/10 of the electric water heater, so the possibility of harm has reached very little and negligible.

Q: How much does it cost to install solar energy in rural areas: Two see insulation performance. The storage tank is a hot water storage tank, and its performance is mainly reflected in the insulation effect. Good insulation not only depends on the thickness of the insulation layer, but also insulation materials and processes. The use of automatic numerical control constant temperature and constant pressure quantitative foam, high temperature curing, thickening insulation layer of the water storage tank to ensure that the layer is more compact symmetry, thermal insulation performance is more durable.Three see bearing strength. Like the solar stent skeleton, of course not fragile. At present, there is a more streamlined tower support, which uses reinforced, super high base, to overcome the traditional thin rod bracket thin wind resistance of the problem, wind, rain, hail, corrosion resistance.

Q: Now there is no sun, cloudy days can use solar products?: The amount of radiation of solar water heater is the meaning of the sun. The sun did not reach that he cannot.

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: Solar energy application technology, there is no prospect: At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.

Q: Solar panels with single crystal silicon or good thanks: Working principle: sunlight to the solar cell plate produced by the current through the inverter controller of the battery, the battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered:1, the actual total power (load) and the use of time, should be reserved for the normal operation of the system;2, the local effective sunshine time, the proportion of rainy weather;

Q: Are solar panels now in use?: Its function is similar to the frequency converter acting on the common AC motor, which belongs to the servo system.
