Using data processing and applying computer algorithms it can be possible to make this energy system more efficient. This paper represents the principle of on-grid photovoltaic cell system and characteristics of its components. A microcontroller based data acquisition system used to collect data from panel. The system compromises of data acquisition system, Zigbee and RS-232 communication modules and computer that permit user to collect data wirelessly. 8-bit 40-pin Atmel AT89C51 type microcontroller used to monitor. After collecting data wireless communication module Zigbee and serial communication module RS232 used to transmit collected data to user computer. Characteristics and operation of setup complete system provided and result of this experiment show that data acquisition is simple and stable. Keywords: solar energy, photovoltaic cell, data acquisition, microcontroller, communication, serial, Zigbee. Introduction Renewable energy resources are becoming one of primary sources of energy due to its abundance. Today, as civilization grows rapidly various challenges are occur in front of energy structure. Because of interest regarding pollution and global warming demand of renewable energy resources are increased. Solar energy is most promising source of renewable energy sources because of its abundance, versatility and environmental friendly nature. Evolution and utilization of this energy not only provide way to use of these resources but also produce efficient assessment to adjust resources in better way to overcome energy resource crisis. There are different environmental and geographical factors that affect resources, so measurement of solar resources under these factors make system cost effective and enhance usage rate of renewable solar energy. Data acquisition helps to measure status of solar systems under these factors. Accuracy of data acquisition system is also important because
