Smart PV Solution

With the most advanced automatic control, network communication and software technology, to obtain PV terminal data in a real-time manner, realize information monitoring, smart remote management, energy consumption trend assessment on photovoltaic device, and rational management and optimization of energy resources.

Solution Summary

The government supervision department lacks centralized management means and channels for current photovoltaic energy projects, lacks information technology and data visualization control platform, and has low monitoring efficiency for energy enterprises, and lacks data support for resource allocation, which leads to huge waste of energy resources. Energy production enterprises and energy service organizations face difficulties in locating energy device fault, and maintenance manpower cost is high. Device operation monitoring is insufficient, thus cause safety risk problem.

Photovoltaic monitoring solution combines the most advanced automatic control, network communication and software technology. By grasping the operation status of massive energy terminal, to obtain status, location, scope, capacity and other data in a real time manner. By model analysis on these data, it can remotely monitor and implement alarm management on photovoltaic terminal device; realize information monitoring, smart remote management on photovoltaic devices. Through the mining and analysis on energy consumption data, make energy consumption trend assessment, to achieve rational management and optimal allocation of energy resources.
