Q: What is the difference between photovoltaic products and solar energy?: Photovoltaic and solar energy is a concept.Photovoltaic (Solar Power): solar photovoltaic power generation system (Solar power system) for short, is a kind of semiconductor material using solar photovoltaic effect, will be directly converted to a new generation of electric power system with solar radiation, operate independently and grid connected in two ways.

Q: Solar products must be in the sun: Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)

Q: Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers: Second, the earth, no matter where there are solar energy, can be developed and used in the field, there is no transport problem, especially for the underdeveloped rural areas, islands and remote areas have more value. Third, solar energy is a clean energy, in the development and utilization, will not produce waste residue, waste water, waste gas, no noise, but will not affect the ecological balance.

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: 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?: Give you an example, for example, the same car, are four wheels, but Mercedes Benz and Xiali price is much worse, because Mercedes Benz safety good quality is high, can ensure the safety of life, your value

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 state has introduced the relevant subsidy policy, fairly good prospects.Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

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.
