Solar lighting system provides a comfortable level of illumination in one or more rooms of a house. The Solar Home lighting system consists of a Solar panel, control electronics, battery, and luminaire(s).
Stand-alone solar PV systems work with batteries. The solar energy is stored in the battery and used to feed building loads after conversion from DC to AC power with a stand-alone inverter. These systems are generally used in remote areas without grid supply or with unreliable grid supply. The disadvantage of these systems is that the batteries require replacement once in every 3 5 years.
