Q:What is the difference between the expensive solar energy and the cheap one?

Give you an example, for example, the same car, are four wheels, but Mercedes Benz and Xiali price is much worse, because Mercedes Benz safety good quality is high, can ensure the safety of life, your value

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:What are the disadvantages of traditional solar water heater

As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?

Q:Monocrystalline silicon market when the turnaround, to what extent

China's solar photovoltaic industry is not a bright prospect of solar photovoltaic industry competition and traditional fossil energy competition. As a result of fossil fuel causes global warming, the world is looking for new alternative energy program, the EU put forward in 2020, the substitution of renewable energy to reach 20%, 2050 reached 80% - 100% plan, Chinese also proposed in 2020 reached 15% China the proportion of non fossil energy, so in the future alternative energy plays a leading energy what is energy?

Q:Solar electric vehicle charging device

Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.

Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater

What solar products:The current solar products include: solar water heater, solar lamp, solar battery, solar power, solar fan cap, solar fan, villa solar power systems, solar flashlight, solar charger, solar cars, solar powered aircraft etc..The main components of solar water heater: flat solar water heater, vacuum tube solar water heater, wall mounted solar water heater.Solar lights include: solar street lights, solar garden lights, solar home lighting.Solar cells are: silicon solar cells, multi compound thin film solar cells, nano crystalline solar cells, organic solar cells.

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: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:In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?

The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.

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.
