Solar Power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP).Photovoltaic convert light into electric current using photoelectric effect. The basic element of a PV system responsible for this conversion is the solar cell which produces direct current (DC) power when exposed to sunlight. The DC power thus produced fluctuates with the intensity of the irradiated light. This usually requires conversion to certain desired voltages or alternating current (AC), which requires the use of inverters Multiple solar cells are connected inside a module Modules are wired together to form arrays, then tied to inverters, which produces power with desired voltage and frequency/phase. Concentrated Solar Power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam to boil water which is then used to provide power.

Experimental Solar Power – Concentrated Photovoltaic (CPV): CPV systems employ sunlight concentrated on to photovoltaic surfaces for the purposes of electric power production. Solar concentrators are often mounted on a tracker in order to keep the focal point upon the cell as the sun moves across the sky.
