Q:What is the future of solar power

Those who despise misleading consumer advertising! 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:Solar electric vehicle charging device

Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.

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:Product category and comparison of solar thermal utilization

The solar industry did a survey on the overall evaluation of the use of solar energy users, think very satisfied with only 3.5% basic satisfaction was 12.6%, average and unsatisfactory accounted for 35.2% and 48.7%; the user evaluation of the service, satisfied and satisfied for a total of 24%, and that no service dissatisfaction accounted for 76%.

Q:Solar energy products, that is, I would like to open a home solar products Daquan

Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it

Q:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?

Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of

Q:Solar products must be in the sun

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

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:How to make solar energy?

Many products using solar energy.1 boxes, 1 plastic bottles and cans; paint, glue, aluminum foil, plastic cloth; out of the plastic foam, metal bottle and transparent plastic paper, ready to do a solar water heater. You can do it.

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
