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.
