Q:Are solar panels now in use?

Servo drive, also known as "servo controller" and "servo amplifier", is used to control the servo motor

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:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about

2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee

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

Solar water heater solar range solar heatingSolar energy air conditioning hot water system solar panel solar energy power generation system encapsulation glue film solar battery lawn lamp garden lamp scenery complementary lamp signal lamp landscape lamp buried lamp

Q:Solar energy products, that is, I would like to open a home solar products Daquan

You come to buy a small brand, I guarantee the same brand and the water temperature. There ah, is to buy low in quality, the water temperature is much higher than the big brands, better quality, but the price is low. This is the answer to the water heater. Now I have to answer your question: I think a large and complete solar business success is unlikely, because you can do fine, because no sales manufacturers will hate you, you will not get a low price, so in the competition you will be in a passive position. There is a large investment in the business field, but this is taboo, because you invested huge output and small, out of proportion. As the election, do fine, do in this field, you are the boss. Others want to see your face. You can make a big profit this time.

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:Solar energy items in daily life

Solar water heater, charging treasure, rotating wheel, battery board Solar cell / solar engine

Q:Buy solar water heater mainly look at what?

Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times

Q:What are the references of the solar automatic tracking system

This paper studied the sun automatic tracking of the independent photovoltaic power generation system based on solar photovoltaic power generation as an important way of utilization of solar energy, the development prospects are very broad. At present, the photovoltaic power generation system with fixed form, the power system has the disadvantages of low power efficiency, high cost and difficult to promote.

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

Solar panels can not be used directly to charge mobile phones and other products. The output voltage of the charger for mobile phone and other products at around 5V, and the output voltage of the solar panel is not fixed, fluctuated, when more than 5.5V or higher, causing permanent damage to products such as mobile phone, must control the output voltage between 4.5 ~ 5.5V through the conversion circuit.Built in battery is in order to output more stable, but the premise must be configured safe and effective protection circuit and voltage conversion circuit.
