1.1 INTRODUCTION Energy is vital for human survival and development. Most of today’s energy comes fossil fuels and Biomass. However these types of fuels are deplitable and emit green house gases e.g. CO2which leads to global warming. (See Fig 1.1).On the other hand, renewable energy is inexhaustible and does not any produce green house gases that can pollute the environment. Therefore there is need to shift to renewable sources of energy. Figure 1.1: A graph showing energy consumption and development between 1965 and 2010 ( For example, in Kenya here is a large geographical imbalance in electricity demand and supply. For instance electrification rates ranges from 15-20% nationally and at rural it ranges from 5-10%. Electricity only accounts for 10% of the total final energy consumption. 60% of all electricity is consumed by commercial and industrial sectors. Only 24% is consumed by households. The demand is rapidly increasing and there is need to incorporate renewable energy in the energy sector in order to make Vision 2030 a reality. Renewable energy is the energy that comes from sources that are continually replenished. This include: solar energy, wind energy, hydropower, ocean energy, geothermal energy. One of the promising renewable sources of energy is solar energy. Solar renewable energy has many advantages and these include: Plenty of resource: The sunlight reaching the Earth’s surface is abundant approximately 8000 (120000 TW/Hr) times
