Is your solar plant
We can help.
When it comes to plant underperformance, root-cause analysis and field diagnostics testing and investigation can uncover complex problems that routine maintenance may not. Borrego O&M resolves these issues through performance engineering and repairs or upgrades, helping to bring solar plant production back to optimal levels.
Recent Projects – Plant Diagnostics and Repair
80 MW ground mount portfolio
Borrego investigated declining project availability and identified existing and incipient module failures causing inverter downtime. Issues lead to warranty claims with OEM.
The lower edge of the image above shows where the internal component degradation and failure occurred.
3.2 MW rooftop portfolio
The Performance Engineering team investigated the root cause of failures in combiner boxes leading to thermal events and identified that the combiner boxes were mounted improperly, horizontally rather than vertically, leading to water intrusion damage.
Images above show the interior condition of the properly versus improperly mounted combiner boxes after more than 10 years of operation.
1.6 MW roof mount portfolio
The Performance Engineering Team determined cause of poor performance as heavy soiling and underperforming strings from rooftop equipment shading not originally modeled during the design phase.
The charts above show the data for daily performance index of inverters on site for the year 2021.
“We’ve worked with Borrego’s O&M Special Projects Team on a few occasions and have found them to have good communication and schedule adherence, and a quality work product.”Katelyn Edgar
Solar Plant Diagnostic Tools
We use in-field technology to perform site investigations combined with desktop reviews of DAS performance data and preventative and corrective maintenance case data to perform root cause analysis. Aerial drone flyovers and thermography analysis software can help reveal hot spots that warrant further on-site investigation. Further in-field testing is done following our equipment and manufacturer-specific technician iPhone checklists.
Solar Plant Repair & Upgrades
From our site diagnostic and root cause analysis work, we make recommendations for performance improvement. Putting our decades of solar engineering and construction experience to use, our O&M Special Projects team provides system owners quality engineered designs that meet code, permit, and utility requirements. Our field technicians perform the installation work, or we work with one of our preferred subcontractor partners all while keeping the project on time and on budget.
