In order to make everyone more full understanding and understanding of solar energy products, we will solar garden lights, solar lawn lamps and ordinary garden lights, ordinary lawn lamps for the following comparative analysis: First, the economic analysis of economic comparison: simple economic analysis Lies in the use of digital statistical methods, clear and clear to solve the problem. Here, we form the form of the lamp prices, installation costs, supporting costs, the use of consumption, safety and other aspects of the five aspects of data calculation. Let's take the following two comparative cases.
Security: As the energy used by ordinary lamps for the exchange of electricity, in the 10 years of use will occur during the pipeline aging, there is a very serious security risks. Safety: solar lighting is less than 36V safe DC, there will be no security problems. The following basic conclusions can be drawn from the above table: 1, the product itself, the solar lamps than ordinary lighting cost is higher; 2, in this case, if the cost of the entire construction process into account, the installation of solar lighting 3, the larger scale, the higher the cost of installation of ordinary lamps, the initial investment will be higher than the solar energy lamps; the same time, the average investment in the installation of ordinary lamps and lanterns; 4, operating costs, the ordinary lamps were significantly higher than the solar lamps, and will be higher and higher (electricity, labor, etc.). 5, the use of stability, the popularity of solar energy weather and the use of environmental impact is its weakness (by changing the control mode to enhance stability), should not be used in the lighting requirements of very strict places. Note: According to the conventional district in accordance with the Beijing Municipal Price Bureau Beijing price (room) word [1997] No. 341 "on the residential district street lamp maintenance fee approved" "pure residential building area of ??a one-time collection of street lights maintenance fee 6 yuan / square Rice "provisions, making the initial investment in general lighting than the initial investment in solar lighting a lot. In short, a comprehensive comparison, solar lighting to save investment characteristics is quite obvious. Solar road lighting than ordinary power road lighting to save about 31.7% of the gold fee. Second, the social benefits analysis: a technology, a product with economic benefits is a good thing, but its vitality, and whether it is compatible with social development, whether it has a social relationship beyond the other products have a direct relationship. Solar energy technology and the emergence of products, in line with the needs of social development, in line with environmental requirements, the social benefits brought about by ordinary products can not be compared
