Q:New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.

As a result, the room window has become a new type of "solar window", "guide" the sun gathered on the four sides of the solar cell. The previous solar cell concentrator, is the use of large areas of moving mirror to track the sun. It is only in the roof and other open areas to set up the previous condenser. In contrast, solar windows do not take up space, easier installation and low cost.

Q:How to promote the use of solar energy in China

Can you be more specific? Because I'm working on a project report, it's best to talk about two aspects of government and solar energy companies

Q:What are the disadvantages of traditional solar water heater

Lift people on science and technology, doubt, this contribution should be attributed to the Tsinghua sunshine and Emperor Ming in the past few years, their initial promotion products contributed to improvements in the manufacturing process, the product has also made a contribution. Make people know the solar water heater.

Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers

Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.

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.

Q:What are the third generation solar cells

Major technical breakthrough:Multi junction solar cellNanostructured solar cellsPhotoelectrochemical solar cell

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: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:Good solar polymer or monocrystalline

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;3, the local meteorological data, such as sunshine time, weather disasters, storms and so on;4, the construction site must be open, in the installation of solar cells can not be tall buildings or other things blocking the sun;

Q:Solar heating easy to use? Has anyone used it

Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
