Q:Solar garden lamp product parameters

* storage battery: fully enclosed maintenance free lead-acid battery 15V20Ah - 80Ah* light source type: energy saving high power integrated LED, rare earth high efficiency energy saving lamp* protection level: IP65* use temperature: -30 degrees to 70 degrees, wind resistance is more than 150Km/h* lighting time: adjust as needed* pole height: according to need

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

Cohesive light film vacuum tube is used their thermal power generation technology, positive negative light, heat, warming faster, higher water temperature, which is unique in the world (Himin patent, ultra cold polar tube, Antarctic expedition team designated products, 40 degrees below zero still out of hot water, hot water is not broken; they are equipped with low winter) the temperature of the water level sensor, accurate induction, automatic operation of the whole system, you don't have to worry about is not water ah, can bathe ah; not only that, once the hot water machine what, their customer service staff will serve you within 48 hours. This is not high price but not expensive, is the value for money, or even value for money?

Q:What are the disadvantages of traditional solar water heater

We now have a factory in Wuxi, the production of solar water heaters, the core components - superconducting heat pipe, so that the product in place. Heat pipe is a vacuum glass tube inside, no leakage, no water absorption of solar heat, but the use of dark metal materials such as heat transfer, heat transfer efficiency is high temperature superconducting material.

Q:How much does it cost to install solar energy in rural areas

The question is more ambiguous, the installation of solar energy in rural areas there are many kinds of circumstances, is not used all year round, is not the villa type, is not the need for surfing the bathtub?Install solar energy in rural areas, the number of homes decided to install what kind of solar energy.

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

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:Buy solar water heater mainly look at what?

Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.

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:Good solar polymer or monocrystalline

Working principle: the light of the sun to the solar battery plate current generated through the inverter controller for battery charging, 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:

Q:Solar energy application technology, there is no prospect

At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.
