Rural PV Solar Parks

Monitoring and Control

Solar energy has been growing strongly in recent years, due to rapid technological developments in Photovoltaic (PV) panels and batteries. PV arrangements for rural areas brought new challenges, particularly in what concerns to online monitoring and control of equipment and production in remote areas. Nowadays Rural PV Parks still have no such monitoring and control systems, which significantly increases the risk of power outages and limits the quality of the service offered.

Eneida has developed an innovative and robust solution to remotely
monitor and control both performance and condition of Rural PV Parks.

The Eneida’s Rural PV Solar Parks solution

It is based on the smart device EWS GIP-rg, with aquisition, processment and communication capabilities, that works as the core of a modular and integrated system.

By default the EWS GIP-rg is able to acquire, log and process data coming from PV panels or string groups as well as from PV inverters, thus allowing for a very detailed monitoring of the asset. The EWS GIP-rg is also a Wireless Sensor Network gateway that allows the integration with other monitoring and control modules in order to enrich the capabilities of the system as a whole. Finally, it also supports communications via GPRS and GSM, making it ideal for integration with remote systems and software.

Monitoring and Control Extensions

The EWS GIP-rg, being a wireless smart device able to communicate within a WSN over the ISM 433MHz, 868MHz or 915MHz band, has the flexibility to increase the number of monitored parameters (such as humidity, temperature, sunlight, etc), as well as its control functionalities, with very low implementation costs. This is done by adding extra sensors and actuators that easily integrate with the EWS GIP-rg.

Theft and damage detection is an important example of a monitoring extension to the GIP-rg.

Integration with Third-party Software

The EWS GIP-rg communicates over GRPS using the HTTP/HTTPS protocol and is prepared to interact with REST APIs. This makes its integration with third-party softwares as easy as possible.
