For remote areas, there are various types of solar systems that can be integrated, depending on the scale, location, and purpose of the project. Off-grid systems are standalone and provide electricity to individual households or small clusters of users. Components include solar panels, batteries, inverters, and charge controllers, which can power basic appliances such as lights, fans, and mobile phones. Mini-grid systems are small-scale networks connecting multiple users within a limited area and provide electricity from a central generation source. These systems typically have a distribution system, a metering system, and a backup generator. They can power more diverse loads such as refrigerators, pumps, and machines. Grid-connected systems feed electricity into the existing grid and provide an alternative or supplementary source of power for the remote area. These usually have a grid-tie inverter, a protection system, and a monitoring system. They can reduce the dependence on fossil fuels and improve the grid stability and reliability.
