Successful Implementation of Solar Monitoring System for APM Solar in Payao

We are excited to announce the successful completion of a solar farm monitoring system for APM Solar in Payao. The site had been operating without a monitoring system until O&M engineer K. Nattawat discovered our services and entrusted us with the project.

Project Highlights:

Challenges with Fiber Optic Wiring:

The site presented a unique challenge as the fiber optic wiring was laid without terminals, and the labels on the wires had completely faded. To avoid excessive costs, we hired local fiber technicians in Payao to handle the fiber splicing and signal testing. The job was executed flawlessly, demonstrating our commitment to resourceful and cost-effective solutions.

Installation of a New Weather Station:

Initially, the site lacked a weather station. We installed a new set, but encountered challenges when integrating devices from China and Europe on the same RS-485 BUS. Thanks to our expertise in electronic design, we were able to successfully combine these systems, ensuring efficient and accurate weather monitoring.

Handling Non-English Equipment:

The DC current meter modules in the combiner boxes were imported from China and came without English documentation. Fortunately, one of our skilled engineers is proficient in Chinese, which enabled us to locate the necessary documents online and fully comprehend the Modbus register specifications.

Exceptional Support from O&M Engineer K. Nattawat:

What truly impressed us was the passion and skill of O&M engineer K. Nattawat. Despite working alone, he provided excellent support throughout the project. His proactive approach was highlighted when he swiftly replaced a faulty inverter with a functioning one from another part of the site. This quick thinking minimized energy loss and maximized output, significantly benefiting the site owner.

This project not only showcases our technical capabilities but also highlights our ability to collaborate effectively with on-site personnel to overcome challenges and achieve great results. We are proud to support APM Solar in enhancing their operational efficiency and look forward to future opportunities to innovate and improve.

Project Solar Monitoring System Site Saraburi 5MW

17th Jun 2017 : Install String Level PV Monitoring System

Blue Solar Solution Co., Ltd. has been entrusted by Irradiance Solar and Jetion Solar to install a Solar Monitoring System for monitoring the operation of Solar Panels at the string level in a 5MW Solar Power Plant project located in Ban Mo District, Saraburi Province.

Blue Solar Solution has connected 54 Combiner Boxes, allowing for the monitoring of up to 864 PV Strings, which covers more than 17,000 solar panels.

On the installation day, the solar irradiance reached 1,100 W/sq.m. in Saraburi Province, making it an ideal location for Solar Farm development.

If any solar panel in a string is underperforming, it affects the overall performance of the entire string, which consists of up to 20 solar panels. Due to the series connection among the panels, the current flowing through the entire string is uniform and equals the output of the least performing panel.

Therefore, installing a monitoring system capable of delving into the performance at the string level is crucial. It ensures that the invested capital yields the highest possible returns in the future.

At Blue Solar Solution Co., Ltd., we have a team of engineers specialized in monitoring systems. We can provide consultation and assistance in installation, configuration, and design of data connections for various devices to ensure timely project completion.
