As a result, the comprehensive sustainability assessment is a big issue in the feasibility study of solar based street lighting systems. The feasibility study of street lighting system based on energy saving analysis and economic feasibility have been highlighted in a number of research projects , , , .
However, solar PV powered street lighting system has also two important shortcomings: (1) the devices have a relatively higher price than grid electricity from traditional electricity generation; (2) a bigger size of energy storage component is needed, because of the time difference between the energy resource peak and electricity consumption peak.
A study performed by the European Commission has shown that between 30% and 50% of electricity used for lighting could be saved by investing in energy-efficient lighting systems . In Spain, in some municipalities, the consumption of energy in public lighting reaches up to 80% of the total electricity consumption.
The present paper investigates and compares the economic feasibility of two types of systems: islanded and grid-connected system, for the street lighting systems in Hunan Province, China. Based on two options of solar panel materials, a simulation model of the system is developed for economic, technical and environmental feasibility.
The major findings from the systems’ modelling of the 14 cities of Hunan Province are outlined below: For 80 watts PV based street lighting systems, the cost of energy (COE) of single crystal panel system is about 0.4–0.5 CNY/kW h more than the polycrystalline system.
Overall, these studies are all able to confirm that under their local solar irradiation, the energy consumption of street lighting system is significantly reduced by integrated solar energy devices, but the extent would vary from region to region.
