One of our customers, an O&M provider managing several utility-scale plants, received the thermographic results for a 50 MW solar farm. They need to quickly identify critical issues, launch warranty claims, and address vegetation and soiling, yet site managers and technicians feel overwhelmed by massive spreadsheets.
Their dataset is massive: hundreds of hotspots, module and string defects, warranty-relevant failures, shading, vegetation, and soiling. Managing this manually was unsustainable. Without the right tools, finding what truly matters is time consuming.
Let’s look at how they solved this challenge using filtering functionality of Sitemark.
The team needs to quickly identify critical hotspots, vegetation and soiling issues, and warranty-related defects.
Their main goals are to:
Locate the most relevant findings for each team
Initiate the warranty claim process promptly
Generate filtered reports for different stakeholders
Here is the workflow the O&M team followed:
The analyst opens the inspection and selects the Filters button.
From the Thermal Anomalies layer, they create a rule such as:
Hotspots and Multi hotspots with ΔT > 10 °C and all the physical internal issues.
Immediately, the map view updates to show only anomalies matching those conditions. A dataset of thousands shrinks to a clear list of high-impact issues.
Then, the analyst creates a filter to focus on defects eligible for warranty claims so the team can quickly identify issues that can be officially documented, and submitted to the manufacturer, ensuring faster resolution and proper coverage under warranty.

Last, the analyst would like to flag vegetation, soiling, and droppings issues to quickly trigger cleaning and trimming activities on-site.
After applying the filters, the map instantly highlights the affected areas, allowing teams to target cleaning or trimming efforts efficiently and focus maintenance where it’s needed most.
The Analyst saves all these filters so all team members can access the same view without recreating it each time.
💡Tip: After setting up your filters in Sitemark, make sure to save them so you can quickly reuse the same filter later!
With the filter applied, the analyst generates a PDF report or creates a link.
Only the filtered anomalies appear in the document, ensuring the client receives:
a concise list of issues, clear visuals, no unnecessary information.
Outcome
By using Sitemark’s filtering, the O&M team achieves:
Faster decision-making by narrowing thousands of points down to the most relavant ones for the team
Clearer communication between analysis, reporting, and field teams
Higher-quality reports tailored to client expectations and on-site technicians
