This paper investigates the outdoor performance of a 20 W monocrystalline silicon solar module in
relation to air mass (AM) in Kakamega. Direct measurement of air mass and module output
parameters from experimental setup was done in Kakamega at a location 0.28270 N and 34.7519
E. Experimental results showed a decrease in ISC and VOC with increasing AM. The maximum
output power produced by the module reduced with an increase in AM. Maximum power was
therefore seen to be produced at noon in this region. VOC increased from 19.47 to 20.04 then
decreased to 19.49 V while ISC increased from 0.36 to 1.19 then decreased to 0.48A. It was
observed that both the FF and of a monocrystalline solar module increase with increase in air
mass. The module performed better during the afternoon than morning and evening hours with the
peak performance observed close to AM 1.
