Q:Solar panels can be charged directly to mobile phones and other products
Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.
Q:What are the third generation solar cells
What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!
Q:Solar industry products trade prospects
Base salary is not high, the Commission is generally 1-2%, different places.
Q:Solar products must be in the sun
Solar energy products are generally inseparable from the sun, but there are also some of the solar radiation energy demand for smaller products
Q:Buy solar water heater mainly look at what?
Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
Q:Product category and comparison of solar thermal utilization
What is the reason?The main reason is that China's solar energy (water heater) is the most in-line vacuum tube solar water heater, vacuum tube itself is vulnerable, tube explosion caused by vibrations, icing, improper water and other reasons, the vacuum tube fouling phenomenon is very serious, affecting the normal use, needs a great amount of customer service service, high maintenance costs. Once, encountered bad weather, frequent accidents, too busy to attend to all enterprises and dealers.Where is the way out?According to the experience and lessons of foreign countries, the use of a new type of high-performance flat solar energy is the most feasible and effective solution.
Q:Solar electric vehicle charging device
Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.
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:30MW solar thermal power plant total investment
At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price
Q:Is there any water in the solar energy to water?
Yes, but it's best not to add water during the day
