5 FAQs about Ghana solar street light power supply system

Can solar power be used for streetlights in Ghana?

Again, the socio-political climate in the country complicates the design process by not allowing for ample time for a thorough design work to be done before incorporating streetlights onto the national grid. This paper discusses the use of solar power as an alternative source of electrical energy for street lighting in Ghana.

How do streetlights work in Ghana?

Streetlights in Ghana receive electrical energy from the national grid. To pay for the energy consumed, residential consumers on the grid are levied 0.0001 of their total monthly consumption. Unfortunately, these levies are inadequate to defray the cost.

Are Ghana's streetlights metered?

There is therefore the need to look at other alternative sources of electrical power, which do not depend on the national grid to light the streetlights. The findings show that most streetlights in Ghana are not metered, thus making it impossible to bill the respective District Assemblies.

Is the NPV of a grid-powered street light higher?

This study however shows that at a lower lamp number, the NPV of the grid-powered street light is higher, but as the number of lamps increases, the NPV of the PV-powered system becomes higher than that of the grid-powered street light system.

Does solar street lighting have a lower payback period?

In the context of work done on the economics of adopting solar street lighting (Masoud 2015; Nunoo, Attachie, and Abraham 2010; Wu et al. 2009), this study was able to identify that the grid-powered LED street lighting system has a lower payback period than the PVpowered configuration.
