This document summarizes a solar power system provider in Indonesia and provides examples of solar power systems installed at telecommunications towers. The company designs, installs, and maintains solar power systems, including grid-connected and off-grid systems. It describes two solar power systems installed at telecom towers, one a hybrid solar-wind-battery system providing 40 kWh per day and another a 12 kW solar system providing 52.8 kWh per day to meet the towers' power needs. Site pictures of the installed systems are also shown.
