Q:What are the disadvantages of traditional solar water heater

Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.

Q:What are the third generation solar cells

What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!

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

Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.

Q:In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?

Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.

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 products must be in the sun

Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)

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

If your house has a little heat preservation effect, the heat collector area is not enough. The first is fraud, very high! Followed by the heat collector is often no place to swing! Again, so many collectors, the heat generated in the summer there is also a problem

Q:There are two years of foreign trade experience of the business to enter the basic salary and commission is what level is reasonable?Products are solar lights, solar chargers, solar power systems, solar power, LED induction lamps and other solar energy products

Yes, for example, solar lights, developing and developed countries are in great demand

Q:The steps of making solar technology stubs

1 with a brush clean eraser material: big eraser, waste brush.Tools: scissors, glue.
