4. INTRODUCTION
 Solar power plant is based on the conversionelectricity, using photovoltaic
(PV), or indirectlyusing concentrated solar power (CSP).
 Concentrated solar power systems use lenses or mirrors and tracking
systems to focus a large area of sunlight into a small beam.
 Photovoltaic into of sunlight into either directly converts light electric
current using the photoelectric effect.
 Concentrated solar power plants first appeared in the 1980s
