PRIOR ART
[002] Owing to the booming of the Internet, the real-time transportation ways nowadays include several wire communication networks, such as the Ethernet and several wireless communication networks, such as the Global Standard for Mobile Communications (GSM) and the General Packet Radio Services (GPRS) to precede the distant data transmission.
[003] It has now become a primary need to do the real time monitoring of the power generation systems for continuous performance. But most of the area usually has no stable electrical power supply and the Local Area Network (LAN) to transmit the real¬time monitoring data. Thus the solar power generation systems which are installed in such areas need to be monitored continuously. Solar systems involve power conditioning units, solar charge controllers, inverters etc. and need to be monitored collectively. Also the solar systems can be integrated with normal/traditional power sources like Grid, Diesel Generator, Gasoline based generators, inverters, uninterrupted power supply etc. The wire communication network is very costly and difficult to build up. If the base stations widely spread are adopted, the wireless communication networks, such as the GPRS or the GSM/CDMA, WiFi, Bluetooth, Zigbee, WiMax, TETRA, 3G and Next Generation

Networks Satellite communication like VSAT etc. precede the distant data transmission.
