Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect. A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect. UniPower focus on PV system in many different applications, such as Telecom applications, grid connected applications, as well a hybrid application to get optimum OPEX and CAPEX.
