Confirm Compatibility and Power Needs
Ring Doorbell 2 supports optional solar panels designed for Ring devices, including the Ring Solar Panel (3W) and certain third-party panels with a 5 V/1–2 A USB output that meet USB Power Delivery specs. Verify that your panel outputs within this range to avoid underpowering or damaging the doorbell. Ring recommends using panels intended for low-voltage USB devices to simplify integration and reduce risk of electrical issues.
Pick Location and Mount the Panel
Select a Sun-Friendly Spot
Place the solar panel where it receives 4–6 hours of direct sunlight daily, avoiding deep shade from trees, roof overhangs, or vents. For consistent year-round performance, tilt the panel toward the equator (south in the Northern Hemisphere, north in the Southern Hemisphere) at an angle roughly equal to your latitude.
Mounting Options and Hardware
Use the included mounting brackets and hardware to attach the panel to a wall, eave, or flat surface. Prefer screws into studs or masonry anchors for stability; if temporary, use high-grip adhesive strips rated for outdoor use and regularly check hold strength. Route the cable along trim or under eaves with clips to keep it secure and weather-resistant.

Prepare the Doorbell and Cable
Before connecting, fully charge the Ring Doorbell 2 battery to 100% to avoid interruptions during setup. Use the USB cable provided by Ring, ensuring the connector fits the doorbell's micro-USB port. Inspect the cable for cuts or fraying, and verify that the panel's USB-A or micro-USB plug matches the cable end. If using an extension cable, choose one with thick conductors and weatherproof connectors to preserve safe current delivery.
Connect and Test
Plug the cable into the solar panel's USB output, route it safely to the doorbell, and connect to the micro-USB port on the back of the device. The Ring app will show charging status; when sunlight is sufficient, the battery icon indicates solar charging. If the battery does not charge, verify the panel output with a multimeter, ensure the cable is fully seated, and check for shadow or debris on the panel surface.
Ongoing Maintenance and Troubleshooting
Keep the panel clean from dust, bird droppings, and snow to maximize output. Periodically check cable clips and mounting screws for looseness, especially after storms. In low-light seasons, expect slower charging; if the doorbell frequently prompts battery changes, consider adding a second panel or temporarily supplementing with a USB-wired charger until conditions improve.
