Abstract

SURVEY OF THE MOST SUITABLE SITE FOR SOLAR STATION IN YOLA, NORTH EASTERN NIGERIA USING LANDSAT-7 ETM+ SATELLITE IMAGE

Hayatu A. A. and *Alkasim, A.

ABSTRACT

Solar radiation is the key to the optimum performance of any solar/photovoltaic device. Identifying the best site to receive of the solar radiation has been the major difficulties for the users of such devices. This paper finds out the best site for optimal performance of solar devices in Yola metropolis, North eastern Nigeria using ENVI 4.5 software and thermal band 6.2 to estimate solar radiance, surface reflectance and surface temperature, from Landsat-7 Enhanced Thematic Mapper Plus (ETM+). Imagery sensors acquired as a digital number (DN) ranging from 0 – 255 in thermal band, were first converted to radiance values (wm-2sr-1 ?m-1) using the bias and gain value specific to the individual pixel, then the radiance was converted to surface reflectance and eventually to surface temperature in (Kelvin). This study reveals the most suitable site for solar station in Yola and these areas are suggested based on the solar parameters during the dry and rainy seasons within the period of study, the areas identified with their locations are: Karewa GRA Extension (9o14’39.93”N, 12o27’3.44”E), Around the Yola International Hotel (9o16’06.93”N, 12o28’07.55”E), FCE Academic Area (9o15’12.39”N, 12o28’21.34”E), Jambutu Motor Pack (9o17’5.19”N, 2o25’25.43”E), Along Airport Road (9o15’57.99”N, 12o25’55.99”E), AUN Administrative Block (9o11’57.71”N, 12o30’05.46”E), Police Roundabout (9o15’31.18”N, 12o27’23.43”E) and Gate II Jimeta Modern Market (9o14’54.78”N, 12o26’58.28”E).
