The role of the various parts:
(1) solar panels: solar panel solar power system is the core part of the solar system, the highest part of the value. Its role is to convert solar radiation to electrical energy stored in batteries or sent to, or promote the work load.
(2) Solar Charge Controller: transistors, resistors, capacitors, inductors form of comparative voltage boost charging and discharging circuit, light control circuit can also be used, or the use of integrated operational amplifier constitutes a voltage comparator hysteresis can also be used microcontroller. Given the general use of the former consider cheap.
(3) Battery: Its role is when there is light energy emitted by the solar panels stored up, and then released when needed.
In addition the design uses a special battery charging management chip UC3906 design solar charge controller, through laboratory testing, its performance to meet the requirements.
Solar energy as a new, first applied in the civilian aspects of the lighting. Currently, in the west light engineering, non-trunk solar lights, solar garden lights and solar lawn lights, solar decorative lights, etc. have been gradually scale. In the design of solar lighting, involving light, solar systems, battery charging and discharging control many factors, any one aspect of the problem will cause a product defect. In this paper, the external characteristics of the solar cell, battery charge and discharge control, solar lighting often makes LED lamps with trichromatic energy efficient comparison and analysis of their respective advantages and disadvantages and the use of the occasion. At the same time on the market for solar lights circuit design problems existing proposed improvements. Since the solar lights that they have unique advantages, in recent years, rapid development. Small lawn lamp power, mainly in the decoration for the purpose of mobility requirements, in addition, the circuit laid difficulties, the high water requirements, so that the above requirements can be powered by solar lawn show many unprecedented advantages. Especially in foreign markets than other solar lawn is a huge demand for the product. In 2002, only Guangdong and Shenzhen for the manufacture of export solar lawn consumes solar cells reach 2MW, was equivalent to a third of the domestic production of solar cells, this year remains strong momentum of development, which is that people did not expect.
