GPRS network used to monitor the generation and use of solar energy in residences

Resumo

The article describes a system for solar power generation, integrated into a "grid-tie" inverter, converting Direct Current "DC", generated by the plates in Alternating Current "AC" on the standards of electrical distribution network. The energy generated is quantified by smart metering module that transmits the information in specified periods of time to a microcontroller via GSM modem. The modem provides the measured data on the internet, using networks and cellular antennas. The monitoring, fault detection and maintenance are performed by a supervisory station. Employed board types, best inverter selection and studies about control equipment and devices have been described. The article covers and explores the global trend of implementing smart distribution electrical energy networks and the incentive to use solar renewable energy. There is the possibility of the excess energy produced by the system be purchased by the local power utility.
