Regular Preventative Maintenance Scans

Our most popular service. Typically at annual intervals, but modulated as site failure rates warrant.

Reactive Troubleshooting Scans

Expedite and support warranty claims, assess extreme weather damage, and investigate under performing assets. We often partner with on-the-ground independent engineering services.

Commissioning or Asset Transfer Service

Full DC health check, establishing a baseline site evaluation.

Portfolio Analysis and Reporting

Our data is analyzed for significant trends across a portfolio to inform our clients’ investment and operating decisions, affording efficient prioritization and planning of maintenance and remediation actions. These trends can be analyzed over time, tracking DC health trends and confirming repairs.

Advanced Analytics

Analysis of our data correlated with other information (inverter performance, IV scans, module serial numbers, etc.) to contextualize and correlate our clients’ issues.


Client Benefits

OWNERS

 

 

Optimize System Performance
We find an average of 1.2% capacity loss for our customers due to string and module faults which are not being found by current O&M practices.

 

FINANCIERS, INSURERS

Proactively Mitigate Risks
100% module-level site coverage ensures that module and O&M quality can be assessed on a regular basis. Our tools allow evaluation of critical risk factors on a regular basis; systemic, latent failure modes can be diagnosed and addressed in their infancy.

 

Track DC Performance
Fault reporting for every module in your portfolio, obtained in a consistent, scalable, and cost-effective way over a project lifetime. Key performance metrics can be compared against industry averages

O&M PROVIDERS

 

Decrease O&M Costs
On-site labor accounts for the largest O&M cost on a PV site. Replacing manual inspection techniques (IV curves, current clamps, etc.) with Heliolytics services can decrease preventative O&M costs by over 10%. With an accurate listing of faults mapped out across a site, your corrective O&M actions are streamlined.

 

 

Increase Site Safety
The use of Heliolytics reduces the number of high voltage combiner boxes technicians are exposed to on a regular basis by over 90%. Heliolytics inspections can identify hot spots and fire hazards which are not detected by manual electrical testing reducing fire risk.


Heliolytics' Process

Reporting: Why It's So Important

Clients rely on our reports to readily identify DC issues and provide clear conclusions to guide their operations and investment decisions. Our results are presented in a detailed report by fault category and severity, with accompanying summary statistics, fault maps, and listings.

Our analysis provides actionable insights, identifying string and module failures in a way that makes the remediation by on-site staff purposeful and targeted. Armed with the knowledge of what is wrong and exactly where faults are located, corrective actions are as efficient as possible.


What Can Heliolytics Detect?

Our service involves the acquisition and analysis of ultra high resolution infrared and visual images for every module in a PV system. With >2.5 GW scanned to date, we compare potential DC faults in your system against our extensive fault library. We have developed an imagery analysis software suite specifically for the PV industry in order to provide our customers with consistent, high-quality results and summary statistics.
