Solar energy is the energy generated by the continuous process of nuclear fusion in the sun's internal or surface sunspots. Earth's orbit average solar radiation intensity of 1367w / ㎡. The circumference of the Earth's equator is 40,000 km, which can be calculated, the Earth's energy can reach 173000TW. The standard peak intensity at sea level is 1kw / ㎡, and the annual average radiation intensity of the Earth's surface is 0.20kw / ㎡, equivalent to 102000TW of energy. Human beings rely on these energies to survive, including all other forms of Renewable energy (except for geothermal energy resources), although the total solar energy resources equivalent to the energy used by humans now more than ten thousand times, but the energy density of solar energy is low, and it varies from place to time, it is development and utilization Solar energy is facing the main problem. These characteristics of solar energy will make it in the whole integrated energy system in the role of certain restrictions.
Although the solar radiation to the Earth's atmosphere is only 2.2 billionth of its total radiant energy, but has reached 173,000TW, that is, the sun per second to the earth's energy is equivalent to 5 million tons of coal. Earth's wind energy, water, ocean temperature difference, wave energy and biomass and some tidal energy are derived from the sun; even fossil fuels on earth (such as coal, oil, gas, etc.) are fundamentally ancient Since the storage of solar energy, so the broad range of solar energy included in the range is very large, narrow solar energy is limited to the solar radiation energy of light and heat, photoelectric and photochemical direct conversion.
Solar energy (Solar Energy), generally refers to the radiation energy of sunlight, in the modern general power generation. Since the earth is the main body of the sun to provide the heat and light to survive, and since ancient times humans also know how to sun dry objects, and as a way to save food, such as salt and salted fish and so on. But in the fossil fuel reduction, the intention to further develop solar energy. The use of solar energy has a passive use (light and heat conversion) and photoelectric conversion in two ways. Solar energy is a new type of renewable energy. The broad sense of solar energy is the source of many energy on Earth, such as wind energy, chemical energy, water potential and so on. Solar home lighting, solar portable light
With the increasing resources of the Earth, the basic energy investment costs are rising, a variety of security and pollution hazards can be described as ubiquitous. In this way, solar lighting products with solar water heaters should be popular after the popular, where we have the effect of solar lighting and the use of electricity fixtures for practical comparison.
* Comparison of a commercial lighting installation complexity: in the city lighting project has a complex operating procedures, first of all to lay the cable, where we should carry out the cable trench excavation, laying the dark tube, pipe threading, backfilling and other large infrastructure projects The And then a long installation and commissioning, such as any one line problems, will have a large area of ​​rework. And terrain and line requirements are complex, labor and ancillary materials are costly. Solar lighting installation is simple: solar lighting installation, do not lay a complex line, just do a cement base, and then fixed with stainless steel screws can be.
* Comparison of two city lighting lighting expensive electricity: commercial lighting in the work of a fixed high electricity, long-term uninterrupted on the line and other configuration maintenance or replacement, maintenance costs increased year by year. Solar lighting free electricity: solar lighting is a one-time investment, without any maintenance costs, three years to recover the cost of investment, long-term benefit.
* Comparison of three commercial lighting has security risks: electricity lighting due to the construction quality, landscape engineering transformation, material aging, power supply is not normal, water and electricity pipeline conflict and so on to bring a lot of security risks. Solar lighting is no security risks: solar lighting is ultra-low voltage products, safe and reliable operation.
Other advantages of solar lighting: green, can be a noble ecological community development and promotion of new selling points; sustainable reduction of property management costs, reduce the cost of the public part of the share of the owners. In view of the comparison, the safety of solar lighting without hidden danger, no energy consumption, green, easy installation, automatic maintenance and maintenance of the inherent characteristics of the sale of real estate, municipal construction directly bring the obvious advantages.
