How to Fix Arlo Solar Panel Not Charging — Troubleshooting Checklist
- Insufficient direct sunlight
- Panel obstruction or dirt
- Loose or faulty charging cable
Problem Description
You have installed an Arlo Solar Panel on your Arlo camera and the battery level continues to drop despite the panel being connected. This quick troubleshooting checklist covers every possible cause in order from most common to least common. Use this guide if you have already installed the panel and it is not working as expected. It applies to all Arlo Solar Panel models across all compatible cameras: Arlo Pro 2, Pro 3, Pro 4, Pro 5S, Ultra, Ultra 2, Essential, Essential XL, and Essential Spotlight.
Why This Happens in Real Homes
Most Arlo solar panel not charging complaints trace to one of three causes: insufficient direct sunlight (50% of cases), excessive camera activity draining faster than charging (30%), or a loose/damaged cable (15%). Actual panel hardware failures are rare — less than 5% of cases. The checklist approach works because users can quickly identify which category their issue falls into and apply the targeted fix rather than trying everything at random.
Symptoms
- Camera battery percentage doesn't increase
- Arlo app shows 'Not Charging' or 'Slow Charging'
- Camera still requires manual charging
- Solar panel is exposed to sunlight
- Charging icon not visible in app
- Happens after panel installation
Recognize these? Here's what usually causes it.
Common Causes
- Insufficient direct sunlight
- Panel obstruction or dirt
- Loose or faulty charging cable
- Extreme temperatures
- Outdated camera firmware
- Faulty solar panel
Most fixes happen in the first 3 steps.
Do not attempt to open or modify the Arlo Solar Panel or camera, as this can void your warranty and expose internal components to weather damage. Contact Arlo Support for suspected hardware issues.

Step-by-Step Solution
Checklist step 1: Is the cable fully connected at both ends?
Check the panel end: the cable should be plugged firmly into the port on the back of the panel. Check the camera end: the magnetic connector should snap onto the charging pins with a definite click. If either connection is loose, the circuit is broken and no charging occurs. Remove and reattach both ends.
Checklist step 2: Does the Arlo app show a solar/charging indicator?
Open the Arlo app, go to your camera, and check the battery section. A sun icon or charging indicator should appear when the panel is providing power. If no indicator appears during daylight hours, the panel is not connected or not generating power. If the indicator appears but battery is still dropping, the panel is working but the camera uses more power than the panel provides.
Checklist step 3: Is the panel getting direct sunlight?
Go outside during midday and look at the panel. Is the sun hitting the panel surface directly? Any shade — even partial shade from a small branch — dramatically reduces output. The panel needs 3-4 hours minimum of unobstructed direct sunlight. South-facing (Northern Hemisphere) or north-facing (Southern Hemisphere) gives the best exposure. Reposition if shaded.
Checklist step 4: Is the camera recording too many events?
Check your camera event history for the last 24 hours. Count the number of motion recordings. More than 20-30 events per day can exceed what the solar panel can replenish, especially with HD or 2K recording enabled. Lower motion sensitivity, narrow activity zones, or reduce video quality to decrease power consumption. If the camera has a spotlight, reduce its brightness and trigger frequency.
Checklist step 5: Is the cable damaged?
Inspect the full length of the cable from panel to camera. Look for kinks, cuts, animal chew marks, or connector corrosion. Outdoor cables are exposed to UV, rain, and animals. A damaged cable may look fine externally but have a broken internal wire. If the cable shows any visible damage, replace it with an Arlo replacement cable. This is more common than panel failure.
Checklist step 6: Is it a seasonal issue?
If the panel worked fine in summer but the battery started dropping in fall or winter, reduced daylight hours and lower sun angle are the cause. Solar output in December can be 25-30% of June levels. Options: manually charge the camera via USB once a month during winter, reduce camera activity to minimum, or accept that the solar panel is a 8-month solution that needs supplemental charging in winter. This is normal and does not indicate a panel defect.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Periodically check the Arlo app for your camera's battery status and charging icon to confirm the solar panel is working effectively. If the icon is not present, re-evaluate panel placement and connections.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
