To improve the efficiency of solar systems, it is very important to get more information about solar panel performance, tracking and maintenance. In this paper data monitoring of solar power system is performed by combination LPC2148 ARM7 Processor and SIM900 GPRS wireless Communication. The ARM7 processor is used for data automatic analysis, processing, displaying and saving automatically whereas GPRS wireless communication device is responsible for real time data transmission to the monitoring center. This system monitors the ambient temperature around solar power generation equipments, humidity, solar irradiation, generated current and voltage by solar panel and battery voltage it also controls the battery charging level.
