Q: Solar products must be in the sun
Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
Q: Solar garden lamp product parameters
* main body material: the lamp post is full steel structure, whole hot galvanizing / plastic spray treatment* solar modules: crystalline silicon 15-80WP (by load configuration)* operating voltage: DC 12V - 24V* controller: solar lamp controller, light control + time control
Q: How to make solar energy?
Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.
Q: What are the disadvantages of traditional solar water heater
As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?
Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.
Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.
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: 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: Are solar panels now in use?
Generally through the position, speed and torque in three ways to control the servo motor to achieve high-precision positioning of the transmission system, the transmission technology is the high-end products.
Q: Solar energy product development prospects?
2012-2016 China solar cell market analysis and Investment Research Report1 solar water heater industry faces new integration. Industry concentration is not high, at present the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. A line of enterprise and brand most high-end centralized development mode, to keep the solar intelligent and widely used will be closer, the solar water heater into the application of high-end, intelligent, integrated, brand enterprises lead the development direction of the industry's highest level and lead the industry, sales of high-end products less.
Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee
