Solar lighting 1

because solar energy is renewable and green, using it to generate electricity can minimize carbon dioxide emission and air pollution. Therefore, solar lighting based on this characteristic has been designed and used in garden and street. The pictures below show this lighting system in garden and street.
Battery pack holder is main part in this lighting system, which includes design of inclination and wind resistant.
1.   Design of inclination
To make sure a solar cell module can receive enough solar radiation in a year, it is necessary to choose the best angle for the solar cell module.
2.   wind-resistant design
In solar street lighting system, it requires wind-resistant design. Wind-resistant design is divided into two aspects, one for wind-resistant design of the battery pack holder, two for the lamp standard.  
There are several advantages of solar lighting system. Firstly, it is energy-saving because solar energy is renewable. Secondly, it is environmental friendly and safe. Thirdly, it costs less due to no maintenance and lower electric charge. Besides, this kind of lighting can ensure regular work at least 15 days in rainy days.
Although solar lighting has significant effects on environment, to develop it still has some barriers to overcome. Next blog will talk about the problems.
