- 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
- Base salary is not high, the Commission is generally 1-2%, different places.
- Q: Solar products must be in the sun
- Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
- Q: Solar garden lamp product parameters
- Rainy days guarantee: can work continuously for more than 15 rainy days (regional / seasonal different) (can be made on request)Without the need for laying underground cables, without payment of lighting, key components of solar panels, solar garden lights the solar street lamp intelligent controller, DC maintenance free storage battery and a lighting lamp through the national development and Reform Commission, the world bank /GEF/ photovoltaic products certification. The utility model is mainly suitable for the lighting and lighting of the city road, the small square, the industrial park, the scenic spot, the park green belt, etc..
- Q: Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
- Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.
- Q: Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
- Solar thermal products are solar water heaters, as well as solar heating systems (usually in the North). Solar water heaters are used in several sets of hot plate, the more common is flat solar and vacuum tube solar two, the former used more in the south, the latter used more in the north.
- 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: Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery
- 1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or
- 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: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.
- Solar automatic drip irrigation systemThe day before, Xinjiang production and Construction Corps three group introduced from Australia two solar automatic irrigation system, used for the first time in china.According to reports, this system is mainly composed of solar panels, automatic controller, water pump, filter, fertilizer tank, field network composed of several parts, it is the biggest characteristic of the photoelectric conversion of DC is generated by solar panel, direct drive pump automatically for the implementation of field crop irrigation, three solar panel configuration, total light area of 3.84 square meters, can produce a voltage of 132 volts, the power of 540W, the amount of water per hour is 2200 liters, 30 acres of drip irrigation can meet the needs; at the same time according to the optical conditions, the system can automatically open and close, the winter slack season, the system can also install conversion equipment, to meet the electricity needs of workers living.
- 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.
