8. Off-Grid Solar Lighting Testing and Reliability

Solar photovoltaic (SPV) LED appliances, e.g., street lights are used in households, roadway lighting all over the countryside area where electricity availability is not proper. This can minimize electricity bills, and being off-grid, it does not depend on grid availability. These LEDs are specially constructed with battery, tested, and certified as per national and international standards. SPV street light installed in the field should work efficiently, but climatic conditions affect the system's long-term durability reliability. Therefore, it is necessary to ensure that the features provided to SPV LED should be highly reliable in its performance and operation. The light should be maintained in an adequate condition with proper security of theft. In this chapter, details about the off-grid LED lighting system are explained. It includes the characterization of PV module in the field and balance of system of lighting systems also.
