Q: For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

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: What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.: Solar energy can solve hot water, power generation, heating, swimming pool, breeding, lighting, cooking, and many other problems, you really want to design a comprehensive utilization of solar energy can find me

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 electric vehicle charging device: Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.

Q: What is the future of solar power: Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.

Q: Is there any water in the solar energy to water?: Yes, but it's best not to add water during the day

Q: Now there is no sun, cloudy days can use solar products?: At present, I have not found this kind of solar energy

Q: Solar energy application technology, there is no prospect: At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.

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
