Rapid increases in energy demand and energy deficiency are two contradicting facts that face developing countries at the present and unexpectedly in the future. Compared to fossil fuel energy generation and nuclear power stations renewable energy (RE) is considered the safest benign energy generation sources. Renewable energy sources are offering the suitable solution for such situations, as had been the answer for remote, isolated dwelling electrification, substituting or integrated with diesel fueled generators. Renewable energy sources are: solar, wind, biomass, hydro, tidal and geothermal. The well known RE sources are; solar, wind, hydro-power, biomass and geothermal. Renewable energy technologies revolve these sources into utilizable forms of energy not only electricity but also heat, chemicals, or mechanical power. There are two modes of renewable energy connection; the first one is connected to grid (on-grid) and the other is isolated or off-grid system.
