Q:Solar energy items in daily life
Solar water heater, charging treasure, rotating wheel, battery board Solar cell / solar engine
Q:Solar panels can be charged directly to mobile phones and other products
Solar panels can not be used directly to charge mobile phones and other products. The output voltage of the charger for mobile phone and other products at around 5V, and the output voltage of the solar panel is not fixed, fluctuated, when more than 5.5V or higher, causing permanent damage to products such as mobile phone, must control the output voltage between 4.5 ~ 5.5V through the conversion circuit.Built in battery is in order to output more stable, but the premise must be configured safe and effective protection circuit and voltage conversion circuit.
Q:What is the difference between photovoltaic products and solar energy?
Photovoltaic technology has many advantages such as: without any mechanical moving parts; in addition to sunshine, without any other fuel, can work in the sun and the oblique case; at the same time solar modules without maintenance, to minimize operating costs; and from site selection, is also very convenient, in the roof of the city open space, can be used. Since 1958, solar photovoltaic effect in the form of solar cells in the field of space satellites for the first time the application of energy. Today, the small automatic parking meter and rooftop solar panels, solar power center to the vast area, its application in the field of power generation has spread all over the world.Solar energy is a rapidly growing form of energy, the solar market has made great progress in the past ten years. According to information, according to the average annual installed capacity of solar power systems, the global solar market composite average annual growth rate of 47.4%, from 2003's MW growth of up to 2826 MW in 2007 to. It is estimated that by 2012, the annual installed capacity of solar energy system may be further increased to 9917 MW, while the entire solar energy industry sales may grow from $17 billion 200 million in 2007 to $39 billion 500 million in 2012. This growth is due in large part to the rapidly growing global market demand, rising electricity prices and various government incentives.
Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Solar energy as a new energy source, it has three advantages compared with conventional energy:First, it is the most abundant energy that human beings can use, it is estimated that in the past 1 billion 100 million years, the sun consumes its own energy of 2%, can be said to be inexhaustible.
Q:Home solar heating products can not mature?
Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time onlineRecommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales
Q:Solar industry products trade prospects
Base salary is not high, the Commission is generally 1-2%, different places.
Q:How about the effect of wall hanging solar energy
Wall really electricity, as to what the effect depends on the brand. Hodge is certainly not good, the water temperature is low in winter. Now a lot of property to buy solar, generally for the hodge. As for the solar energy is better or you use absolute OK Himin - winter!!!
Q:What are the solar products?
Solar water heater solar range solar heatingSolar energy air conditioning hot water system solar panel solar energy power generation system encapsulation glue film solar battery lawn lamp garden lamp scenery complementary lamp signal lamp landscape lamp buried lamp
Q:How to do a good job of solar water heater marketing?
Two, energy saving (cost savings): the impact of solar water heater life components. About the use of solar water heaters for heating homes, can save daily for heating water electricity, gas costs 90%, can reduce household expenses, to the society, can reduce our province limited energy resources consumption, the energy and ancillary facilities for agricultural and industrial production, have greater social benefits.
Q:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heating
