I. Introduction
As a result of increased pressure to reduce carbon dioxide (CO2) emissions into the atmosphere, the deployment of renewable energy systems, mostly wind and solar energy systems is fast increasing in many countries around the world [1]. Among various renewable energy conversion technologies, photovoltaic (PV) systems have gained a stronger integration into the power sector owing to the decrease in prices of solar panels and associate components like inverter, not undermining the huge energy available from the sun [2]. Nevertheless, the adoption of PV technology in Sub-Saharan Africa is still on a low scale despite the abundance of solar resources on the continent [3]. In Kenya, the ministry of energy introduced feed-in tariff policies to encourage the integration of more PV systems into the distribution network [4].
