Solar energy has the advantages of pollution-free, sustainable, large volume, wide distribution and so on. Under the environment of global energy transformation and upgrading, it has been very popular. In addition, China, the United States, India and other countries photovoltaic market development is in full swing, it is more eye-catching.
In addition to the large photovoltaic power station, Xiaobian takes inventory of the current solar application products for you.
Rooftop distributed solar energy
The principle of roofing distributed solar energy is to install solar power plants at the top of the house and use optoelectronic technology to convert the solar energy into clean electricity for use. Such solar energy applications, while supplying electricity to the houses, can also sell surplus electricity and obtain additional economic income.
Although rooftop distributed solar energy takes full advantage of the roof without land, the city of tall buildings is more difficult to popularize, and the suburbs can have a better effect.
Solar energy for windows
The window uses solar energy to install a solar cell with a transparent film or special coating on the window. The conversion efficiency is low, but it can have both power generation and light transmittance.
At present, the installation of solar energy in the windows has been developed by scholars such as the United States and Japan, trying to make the power of solar windows electricity for room lights, computers and even air conditioners, and the appearance of windows can be the same as that of ordinary windows.
Solar ecological greenhouse
The solar photovoltaic power system, the photothermal system and the new nano ecological light transfer film technology are applied to the greenhouse, to improve the photosynthesis of the plants, to improve the quality of the crops and to increase the income of the farmers in the form of environmental protection.
Complementation of fishing and light
That is, laying solar panels on fish ponds, while photovoltaic panels can also generate sunlight, reduce water temperature and promote the development of aquaculture.
Build photovoltaic power stations on the roof of farms to transform and enhance traditional animal husbandry and provide green energy.
Sewage treatment system
After converting solar energy into heat and electric energy, it can be effectively used in sewage treatment. There are almost no two pollution and energy transfer in the process, which can solve the increasingly serious environmental problems in rural areas.
The combination of photovoltaic and agriculture also has some constraints, such as the hard dismantling of solar energy equipment, affecting the new planning of agriculture; in the season of less sunlight, photovoltaic panels cover the sun, reduce plant photosynthesis. In addition, although photovoltaic agriculture has a policy subsidy, its price is still high and does not apply to ordinary farmers' families.
Solar street lamp
Most of the common solar street lamps are powered by crystalline silicon solar cells and stored with colloidal batteries. The ultra bright LED lamps are used as light sources and controlled by the intelligent charge and discharge controllers. The solar panels are charged in the daytime, and the battery is discharged for lighting at night by the battery.
More and more solar street lamps are common in parks, scenic spots, schools and government agencies. However, solar street lamps have problems such as the instability of the storage battery and the insufficient electricity generation in the daytime.
Solar road hub
Foshan, China, has set up the first solar transport hub in China to install solar photovoltaic panels on the roof of a traffic hub, which can be recharged for electric vehicles, except for the use of nearby buildings.
Solar electric electric vehicle and electric bus
Electric vehicles are not difficult to see in life. It takes power as energy and supplies power through the installation of lithium electronic batteries. If it is matched with solar energy, it can reduce the driving cost, do not discharge harmful gases, and do not produce environmental pollutants.
Solar road surface
Laying solar panels on the road can reduce the demand for traditional power plants, using smart sensors to illuminate the lane demarcation line and road signs, and even warn drivers to be careful with dangerous objects. The prospect of solar road surface is good.
In the suburbs of Amsterdam, part of the 100 meter long solar bike lanes (SolaRoad) is paved with photovoltaic cells and covered with tempered glass. Since its opening in October 2014, this road has generated 3000kwh power by May 2015.
With the help of the US Transportation Department and the crowd raising website Indiegogo, a couple of Idaho couples designed solar roads.
Solar fridge is to set up photovoltaic panels outside the refrigerator to collect outdoor sunlight and convert them into electric energy, which is stored in the battery for refrigerators. As early as the "German Boulevard" held in Guangzhou in November 7, 2008, SIEMENS showed a solar refrigerator, which was listed in Germany at the beginning of the following year, with a price of 8000 to 10000 euros.
Solar air conditioning
Solar air conditioning is the main energy source of solar energy and renewable biomass fuel during heating. In cold room, a small amount of electric energy is used, using the low temperature of the ground source, and using the superconducting energy transport system to directly refrigerate, so as to achieve the most reasonable energy saving effect of cold room. It will not consume a lot of energy that is difficult to regenerate, and will not release too much carbon dioxide in the cold room.
In recent years, GREE, Haier and other electrical manufacturers are also developing solar air conditioners continuously.
Solar garbage can
The earliest solar garbage cans appeared on the streets of New York in 2006. A solar panel was set outside the trash can, and a sensor was set inside. It weighed more than the ordinary trash can, and could prevent the smell from spilling and lighting at night.
In China, Mount Huangshan, West Lake and other public places, solar energy trash can also be seen. However, solar energy trash cans are expensive and people are not accustomed to using them.
Solar water heater
The solar water heater can heat the water by converting the solar energy into heat energy, so as to meet the hot water use in people's life and production. In addition to the common flat solar water heater, there are also glass vacuum tube solar water heaters. Solar water heaters are widely used in solar energy applications.
The roof of the solar tent is covered with a thin film of solar energy. When sunlight comes, the thin film converts solar energy into electric energy, which is stored and used for tent lighting. Because of the flexibility of the film, solar tents can be folded, bent and stored arbitrarily.
The combination of solar energy and clothing can make clothes not only beautiful, warm and other functions, but also have functions of charging, lighting, sterilization and so on. Like Parker's coat, Holland designer PaulinevanDongen says the pocket can be full of electricity for smart phones in two hours.
In September 16th, solar powered suitcases sparked concern at the UN's UN-CEFC energy sustainable development grant.
Solar powered suitcase is a light and economical solar energy product. It can store sufficient electricity for emergency operation. It is currently being used in humanitarian relief such as maternal production in Africa, earthquake in Nepal.
Mobile phones are gradually becoming part of life, and mobile power also comes along. Solar mobile power, no need to use electricity, in the solar energy can be charged. Because of its convenience and low price, it is gradually accepted.
The solar notebook is a laptop computer driven by solar energy. Samsung's NC215s sets a black coat on the top, and installs solar panels to absorb solar energy and irradiate for 2 hours in the sun, providing 1 hours of electricity.
Other wearable solar devices
In addition to solar clothing, the wearable device manufacturer Misfit combined with the Shine bracelet set by the swaro world, implanted solar energy, the ring does not need additional battery and charge; it is exposed to the sun or LED light to complete the charge, and can also detect the sleep condition.
