- Q: What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.
- Solar hot water, solar photovoltaic power generation, various solar lamps
- 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: 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: Is there any water in the solar energy to water?
- How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill
- 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: 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: PV solar products market sales
- The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity."According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat.
- Q: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.
- Solar door lock lampThis is a new type of solar lock lamp solar panel for charging the battery, a LED lamp lighting, a full charge can continuously light 720 times, each time for 10 seconds, 10 seconds will be automatically extinguished, this time is enough for you to insert the key inserted the place.
- 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: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.
