As PV power plants continue to increase, centralized management and information integration become thorny problems.Enterprise PV systems mainly supply power for their own needs and may sell excess power to the power company whereas Photovoltaic (PV) power plants specialize in solar energy collection and then feeding the energy into the grid.To transmit the data of the PV systems wired or wireless networks can be used. However, wireless networks have the advantage of flexibility and are the best choice for those who want quick deployment.Taking into account the requirements of wider coverage and long-distance transmission, the existing fiber-optic networks had many shortcomings ie high cost, complicated wiring and long construction period, and it may also have been necessary to excavate walls, drill holes, embed wires, or even destroy the original building structure. After evaluation, the Juli Group decided to adopt an easy installation and easy expansion wireless network system for early completion of this project.
