NIDON Clean Energy welcomes JEBSCO Mechanical, Inc. as a primary design and build partner. JEBSCO’s expertise in commercial and residential HVAC and solar thermal technology is a major value-add as NIDON continues to scale and expand its business into new frontiers.
This chiller is rated to typically draw about 63 amps but with supplementary power from the SunTrac panels, the load across three days in 28°C experienced a 75% decrease with a near steady state amp draw of 16 amps:
eGauge meter reading across a one-day time interval (April 21, 12:10 PM to April 22, 12:10 PM HST)
eGauge meter reading across a 12-hour time interval (April 21, 12:10 AM to April 22, 12:10 PM HST)
eGauge meter reading across a 10-minute time interval (April 22, 12:00 PM to 12:10 PM HST)
Timestamps reflected on the above data captures follow local Philippine time (PHT) and is to be adjusted back 18 hours to depict actual amp draw with respect to time of day in Honolulu, Hawaii (HST).

Along with the massive drop in amp draw, there is a corresponding decrease in the work being conducted by the unit’s digital scroll compressor leading to a significant reduction in the machine’s wear and tear on top of substantial electrical cost savings.
Data is being tracked and recorded by an eGauge metering device in a three-phase configuration and placed inside an outdoor-rated enclosure:

Update: Efficiency data across two week
Below is a screen capture of meter readings for the first two weeks of recording with the eGauge. The compressor amp draw still averages at 15-16 amps, with significant dips between midnight and dawn due to the cooler ambient temperature.
Update: One month’s worth of meter readings
A month of meter readings shows amp draw still at an average of 15-16 amps.
The recorded amp draw by compressors post-installation is reduced by 60%. Energy savings will correspond with amperage drop to the compressors, along with reduced wear.
For the Hawaii market, this is foundational to achieving the Hawaii Clean Energy Initiative which aims to achieve 100% renewable energy reliance by 2045. SunTrac has been successfully deployed across Hawaii on all major brands of air conditioning, to now include commercial systems. The technology reduces demand charges and electrical usage, leading to less land for solar, wind, and battery, protecting the people and the beauty of the islands in the process.

This is the state of our home. And along with its rapidly worsening condition is our obligation to speed up our efforts to save it.
Thanks to improving capabilities and available technology, we are presented with a myriad of ways to contribute to this global mission. As a matter of fact, most—if not all—of these green solutions are win-win for both us and the world.
One such alternative is clean energy. It taps into the world’s existing resources and generates energy by working with natural movements and states. In effect, there are no wastes and energy flows in an efficient cycle that poses no harm to the Earth. Clean energy is fundamentally from the environment and for the environment.
The gains zoom past macro level into our everyday lives. Costs to power our workplaces, our leisure centers, and our homes significantly decrease with the use of clean energy. It is an investment with multifaceted returns.
