Best security camera solar panel: match the panel to your camera model

Updated 2026-11-10 · Pick: Reolink Solar Panel 2 (6 W), $39.99 on Amazon (checked 2026-11-12), buy on Amazon: https://www.amazon.com/dp/B0BGJ2561Q?tag=dealectric-20

Short answer. The best security camera solar panel is the one your camera's maker lists for your exact model: solar panel compatibility follows brand and generation, not watts. For Reolink cameras, the 6 W Solar Panel 2 fits every Reolink battery camera except the original Argus and Keen.

How this table was made: each figure comes from the maker's own US product page or manual, or from the reviewer named next to it, checked 2026-11-10. Dealectric does not test units itself.

What the differences mean

• Reolink 6 W vs Reolink 3 W: 0.97 A ÷ 0.54 A = 1.8× the charging current at the same 6 V, so a drained battery refills in about half the sun-hours.
• eufy 3 W vs the SoloCam S340's included panel: 3 W ÷ 2.2 W = 1.36, about 36% more rated output from eufy's certified add-on panel.
• Ring 4 W: 4 W ÷ 5 V = 0.8 A of rated charging current.
• Cable reach: Reolink's 4 m lead plus Reolink's 9 m extension limit = 13 m (about 43 ft) from camera to panel. Ring gives 2 m (6.5 ft) and Wasserstein 4 m (13.1 ft). Blink's own mount gives 2 ft detached, or 2 + 13 = 15 ft with its separately sold extension.
• Cost per rated watt: eufy $29.99 ÷ 3 W = $10.00/W; Ring $59.99 ÷ 4 W = $15.00/W.

Solar panel compatibility by camera model

Reolink. Reolink's 3 W, 6 W (Solar Panel 2) and 12 W (Solar Panel 3) panels fit 'all Reolink battery-powered cameras except Reolink Argus and Keen', and Reolink's DC-powered cameras can't use them. Solar Panel 2 and 3 use USB-C. The 3 W panel comes in Micro-USB or USB-C versions; for a port mismatch, Reolink says to use a USB-C to Micro-USB cable. Reolink advises no more than 9 m (30 ft) of extension cable in total, because longer runs slow or destabilise charging. The Argus 4 Pro takes only the included USB-A to USB-C cable. All three panels charge only between 0 °C and 45 °C (32–113 °F), and Reolink says charging may stop below 0 °C to protect the lithium battery. For cold sites, Reolink's Solar Panel 2S carries a 5,900 mAh (42.48 Wh) battery that powers the camera directly from 0 °C down to −20 °C, by Reolink's support article. Its product page gives a narrower working range of −10 °C to 50 °C.

eufy. eufy's 3 W add-on panel, the T8705011, fits the cameras in the table. eufy says only certified eufy panels can sync with eufyCam. On the eufyCam S3 Pro, the external panel and the built-in panel charge the camera at the same time. The SoloCam S340's included panel can be mounted away from the camera on the supplied USB-C extension, and eufy recommends a 20°–30° tilt.

Ring. The USB-C Solar Panel plugs straight into the USB-C models. It reaches the barrel-jack Battery and Solar models through its included adapter. Ring lists the 1st-gen Stick Up Cam as not compatible.

VMA5600	Magnetic	VMC4040P, VMC4041P, VMC4050P, VMC4060P, VMC5040, FB1001, VML2030 (not VMC4070 or VMC5050)
VMA3600	Micro-USB	VMC2020/2030/2032 only; not Pro, Go or Security Lights
VMA4600	Micro-USB	VMC4030P, VMC4030, VML4030, AL1101; not Essential

Arlo notes that its panels trickle-charge: they are not built to refill a low battery, and heavy use can drain the battery faster than the panel replaces it.

Not recommended

Blink Solar Panel Mount on a Blink Outdoor 4, XT or XT2. Blink's own FAQ says the mount fits only the Blink Outdoor (3rd Gen) and is 'NOT compatible' with the Outdoor 4, XT and XT2. For those cameras, the Wasserstein panel in the table covers the Outdoor 4 through its USB-C converter.
