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:Solar energy product development prospects?

Summary: 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. Domestic solar water heater market development problems, intense competition. Local laws and regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. The pain of the industry - too frequent flow of talent. The flow of talent of the solar water heater industry is too frequent, among enterprises personnel frequent job hopping, which is harmful for the development of enterprises, but also bring the product homogeneity and marketing homogeneity consequences, market promotion means that the same product function and price of roughly the same situation.

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:For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...

Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

Q:Home solar heating products can not mature?

1, the local climate: the solar water heater solar tube is not winter frost, but many people will find that in addition to solar tube other basically frozen broken in the actual use of the process, all the cold area, far distance roof is not recommended, the summer hail smashed zirendaomei. Before taking a bath before half a bucket of cold water, it is really a waste;2, installation conditions: the water pressure is not good, the floor is high, ready to install solar energy and electric hybrid proposal wash sleep. The related auxiliary equipment comprises a booster pump, a controller, will force you to spend a lot of innocent money, you are hard to feel the donkey3, economic price: the use of the price, the price of solar water heater in more than 3000, 1500 yuan, 2000 yuan while the gas water heater, solar electricity, but the experienced friends all know no electricity solar still can not be used, all can not talk about energy saving. On the use of the cost of natural gas pipeline gas prices in the province, followed by electricity tariffs, the overall cost of speaking, to buy more than 1500 yuan solar electricity tariff equivalent to 3000 degrees, enough for a few years of use.

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:How to make better use of solar energy

According to the history of the use of solar energy, solar energy has been used for more than 3000 years of history. The use of solar energy as a source of energy and power, only 300 years of history. The real solar energy as a much-needed supplementary energy in the near future, the basis of the future energy structure, it is a recent thing. Since 1970s, the rapid development of solar technology, solar energy utilization

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: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.

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.
