Q:What are the disadvantages of traditional solar water heater
We now have a factory in Wuxi, the production of solar water heaters, the core components - superconducting heat pipe, so that the product in place. Heat pipe is a vacuum glass tube inside, no leakage, no water absorption of solar heat, but the use of dark metal materials such as heat transfer, heat transfer efficiency is high temperature superconducting material.
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:What are the current domestic solar energy products, which practical
Our use of solar energy can be roughly divided into two types of light and heat conversion and photoelectric conversion, in terms of household solar water heater and solar photovoltaic power generation.The solar water heater is widely used, manufacturers have Wuxi Suntech, linuoruite, Himin Solar energy, I think the emperor of the more, certainly not bad.
Q:What are the uses of solar energy?
Uses as follows:Photothermal utilizationIts basic principle is to collect the solar radiation energy, and convert it into heat energy. At present, the most widely used solar collector, there are 4 types of flat plate collector, vacuum tube collector, ceramic solar collector and focus collector (trough, dish and tower). Usually according to the temperature and the use of the different, and the use of solar thermal light is divided into low temperature (<200 DEG C), the use of medium temperature (200 ~ 800 C) and high temperature utilization (>800 C). At low temperature using mainly solar water heater, solar dryer, solar distiller, solar heating (solar room), solar greenhouse, solar air conditioning system, the temperature is mainly using solar cookers, solar thermal power generation heat collecting device, mainly using high temperature high temperature solar furnace etc..
Q:Solar energy items in daily life
The solar water heater, solar flashlight, solar micro kitchen, decoration, solar car
Q:Outdoor solar energy products how to process the level of IP65
First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacles
Q:What are the third generation solar cells
Major technical breakthrough:Multi junction solar cellNanostructured solar cellsPhotoelectrochemical solar cell
Q:Solar panels can be charged directly to mobile phones and other products
Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of
Q:Solar garden lamp product parameters
* storage battery: fully enclosed maintenance free lead-acid battery 15V20Ah - 80Ah* light source type: energy saving high power integrated LED, rare earth high efficiency energy saving lamp* protection level: IP65* use temperature: -30 degrees to 70 degrees, wind resistance is more than 150Km/h* lighting time: adjust as needed* pole height: according to need
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.
