THE DESIGN OF PHOTOVOLTAIC ENERGY IN CITY

STREET LIGHTING

ABSTRACT

In the 21st century,with the intensification of the world energy crisis, solar energy is considered as the most common and clean energy. It is focused on by human with its inexhaustible and unpollution advantages. In the human life, the solar PV has very extensive use, the basic form of which can be divided into two categories: independent power generation and combined to the grid. With the development of photovoltaic technology and the need of world sustainable development, the developed countries have also started to promote photovoltaic combined to the grid in the city, mainly to build the PV system of household rooftop and the MW-level large-scale combined to the grid system. At the same time, the application of solar PV in the construction of urban lighting has also been greatly promoted. At present, the domestic solar photovoltaic technology in the city lighting has shown rapid development momentum,such as street lights, signs, lawn lamp of roads, schools, parks, residential quarters and other places, making the city more environmentally, energy saving, convenient and safe in the public lighting.

In order to respond positively to the call of national energy saving and emission reduction and developing low-carbon economy,for the purpose of its
