ECONOMIC COST COMPARISM OF SOLAR ENERGY AND GENERATOR IN POWERING STREET LIGHT
Abstract
The focu® of this study was to compare the cost of solar powered street lighting and
sos! of generator powered street lighting. Data were collected from examining the
street lighting in the major streets in Calabar which is the research case study. cost
analysis for solar and generator powered street lighting was carried out by using
documents obtained from Mantract Nigeria Limited dealers of sales, installation and
maintenance of generating devices. Information about sales and installation of solar
power system where gotten from solar power solution company Ndidem Isang Iso
Road Calabar. In the analysis, considering Etta Agbor, Mary Slessor Avenue,
Marian/Ndidem Iso Road, Parliamentary Road, Calabar Road, and Murtala
Mohammed Highway as major streets in Calabar and using the two means of
powering street (solar and generator) for five years, it was realized that the cost of
generator powered street lighting is higher than the cost of solar powering street
lighting using generator is more expensive than using ar energ :chanism. It
was concluded that, the solar powered street lighting is more cost effective and
environmentally friendly as compare to generator powered street lighting. It was then
recommended that, where electrical energy is needed in large amount and for a long
period, solar power should be first recognized while for electricity backup purpose
like in hospital etc, generator should be used.
