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

Some solar energy is more expensive than other products! But is it worth it?! We do not have a word called a penny a point goods, product quality and price are proportional to

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:Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!

Third, the less the number of parts as possibleFourth, when the whole is a way to allow glue

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:Product category and comparison of solar thermal utilization

Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.

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

Solar energy power supply system for LED street lamp LED floodlightSolar lamp with LED outline lamp solar corridor lampSpecial lighting system for LED pulse cold light beauty lamp tent

Q:Is it hot in summer and the water is hot in winter?

Wall really electricity, as to what the effect depends on the brand. Hodge is certainly not good, the water temperature is low in winter. Now a lot of property to buy solar, generally for the hodge. As for the solar energy is better or you use absolute OK Himin - winter!!!

Q:Solar panels with single crystal silicon or good thanks

The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.

Q:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?

Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.

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

Solar energy can be combined with heating. But it is still defined as "energy saving" more appropriate, rather than defined as "heating". The use of solar energy must be energy efficient. Suggest you can use gas stove heating, more money. If you want to save energy, then the gas stove and solar energy, solar bath, gas stove for heating and auxiliary heating as a solar energy.
