Count solar panels on a roof or array from a photo
Works with JPG, PNG, WEBP · Free up to 20 MB, Premium 50 MB
Shoot the area from directly above in a single pass so the solar panels sit flat in frame and do not hide each other — counted detections receive dots for review. Built for surveyors, site managers, solar installers and car park operators — review and correct each photo before adding it to a CSV or PDF tally.
- Review the photo, then count visible solar panels
- Count without marking; add example boxes if you need a guided recount
- Stop counting the same solar panels twice to be sure of the total

Tips for an accurate count
• Use an even, well-lit photo with the solar panels fully in frame
• Check that each marked example boxes a whole solar panels rather than a repeated part
• Dots and heatmap show retained detections — review and correct the tally
About the Solar Panels Counter
The solar panels counter counts visible solar panels from your photo and marks detections for review. Auto mode uses the selected item name. For a guided recount, mark up to three examples of what you want counted. Visibility, overlap and similar-looking items can affect the total. Built for surveyors, site managers, solar installers and car park operators.
How It Works
1. Photograph your solar panels
2. Check that solar panels is selected, then choose Count
3. Review the markers and correct the tally; add example boxes for a guided recount if needed
4. Add to the tally sheet and export your count as CSV
Perfect For
• Module counts from a drone survey before commissioning
• Checking an installed array against the design drawing
• Asset records for an operations and maintenance handover
• Quick sizing estimates from an existing rooftop photo
Counting solar panels from a drone or rooftop photo
Solar panels are counted by installers and asset teams from a drone survey before commissioning, to check an installed array against the design drawing, for asset records at an operations and maintenance handover, and to estimate the size of an existing rooftop system. The unit matters: a module, a string or a whole table can each be counted, and the counter counts whatever you mark.
Each module is divided into a grid of cells, and close up those cells form a repeating pattern that can be read as many small items. Mark one complete module, frame included, as the example in Similar items so the module is the unit; mark a whole table instead to count tables. Glass reflects the sky, and a sun reflection can white out several modules, so fly with the sun behind you or on a bright overcast day. Shoot as close to straight down as the site allows, since steep angles foreshorten panels and merge rows.
Row by row, check the markers and correct the tally, then add each roof face or block as a labelled row; a PDF report of the tally is available on Premium for a handover file. Vehicles in the site car park can be counted from the same pass with the vehicle counter, and anything else in the frame with the object counter, which takes a typed item name.
Array photo checks
- One complete module or table marked as the example
- Sun behind the camera, or bright overcast light
- A straight-down angle wherever the site allows
- One roof face or block per tally row
Frequently asked questions
- How high should the drone or camera be?
- High enough that the whole area fits in one frame, low enough that each item is still a clear shape — a few dozen pixels across is a good target. Keep the camera pointing straight down and the light even, then review every marker before using the total. Two passes only compare with each other if the height and angle match.
- Does it count single modules or whole tables?
- It counts whatever you mark. Mark one module and it tallies modules; mark one complete table and it tallies tables instead. Panels at a steep angle to the camera foreshorten and can merge, so shoot as close to straight down as the site allows and review every marker.
- What if the photo has more than just solar panels in it?
- Auto mode uses the selected item name to find what to count. For a guided recount, mark one complete, clearly visible solar panels — up to 3 examples for different-looking kinds. Similar-looking distractors can still affect the result, so review every marker before using the total.
- Can I count several photos into one total?
- Yes — count each photo and add every reviewed result to the tally sheet as a labelled row. If you use example boxes, mark them separately on each photo. Export the tally as CSV or a PDF report, or save it to your account.
- Is it free and private?
- Yes. You can count, review and download a free result without an account. Downloads are free without a watermark. No signup required. Server-processed photos are encrypted in transit and removed under our Security policy.
