Yes, if the panel gets enough direct sun, and the makers' own figures for enough run from 10 minutes a day to six hours. Reolink, Blink and Tapo quote under an hour; Wyze about one; eufy one to two; Arlo two; Ring three to six. Every one of them means direct sun on the panel, not daylight. Every figure is from the maker's own pages, read 3 October 2026.
Tapo says this camera keeps going on 50 minutes of direct sun a day, has the panel built in, and records to a microSD card with no plan.

The makers all say yes, and each attaches a condition. The useful part is how far apart the conditions are: a Blink camera on Solaris is said to keep going on less than an hour of sun, while Ring asks for up to six.
| Maker | Panel or camera | Direct sun a day | Under what conditions |
|---|---|---|---|
| Blink | Solaris (Outdoor 4, Outdoor 2K+) | At least 45 minutes | "for optimal performance" |
| Tapo | C465, panel built in | 50 minutes | Lab sunlight, up to 100 events a day |
| Wyze | Solar Cam Pan 2K | About 1 hour | "under normal usage" |
| eufy | S220 / eufyCam S4 | At least 2 hours / 1–2 hours | "normal SoloCam usage" |
| Arlo | Essential Solar | As little as 2 hours | "Depending on settings, use, activity" |
| Reolink | Argus 4 Pro, 6W panel | 10 minutes | Awake 300 seconds a day; 25 °C sun simulated |
| Ring | Doorbell panels / camera Solar Panel | 3–4 / 4–6 hours | Clouds give no charge |
Each figure from the maker's own support or product page, read 3 October 2026. They are measured differently and cannot be ranked against each other; the column on the right says what each assumes.
The gap is not only the panels. Reolink's 10 minutes is for what it calls "Standard Mode, which operates based on PIR triggering and wakes up for 300 seconds per day", from "a 25°C (77°F) sunny condition simulation"; its 3W-panel cameras need 20 minutes on the same table. Tapo's 50 minutes comes with a footnote: "standard environmental conditions (1000W/m2, 25°C, AM1.5) and specified working scenes (up to 100 events triggered per day)". Wyze's hour is for "normal usage conditions". A camera that records two hundred clips a day facing a busy street needs more than its maker's number, which is why Wyze warns against pointing a camera at "swaying trees, bushes, busy roads".
How many hours of sun does a solar camera need?
It depends on the camera, and the makers' figures are far apart. Reolink lists 10 minutes a day for its Argus 4 Pro on a 6W panel; Ring's Solar Panel for security cameras needs "a minimum of four to six hours a day". The table has each maker's own figure and what it assumes.
eufy gives the clearest picture of the arithmetic. Its S340 page says the panel can "collect and store 800 to 1,200 mAh per day" in good sun, and the camera "uses 100 to 200 mAh over a day and night of average use". On a good day the panel makes several times what the camera spends; the margin is what carries it through the bad ones.
Reolink's blog draws the line that matters: "That number only counts peak sun hours, when sunlight hits the panel straight-on at full strength, not the total time the sky happens to be light out." A bright yard under an overhang is not direct sun.
Do solar cameras charge on cloudy days?
Poorly, by the makers' own account. Ring says "Filtered or indirect sunlight through the clouds will not provide a charge to your doorbell"; Tapo that its A201 panel is "essentially unable to collect solar energy" on rainy days; Wyze that its panel "is unlikely to perform well in cloudy, rainy weather".
eufy is the most hopeful, calling a dip in cloudy weather "expected behavior" that recovers "as sunlight improves". Ring's doorbell page puts the practical point plainly: if your installation area "is frequently very cloudy or gets a lot of rain or snow, this could limit the amount of sunlight" the panel gets.
What happens in winter?
The battery carries it. Tapo says the C465 runs "up to 180 days without sun exposure", and Blink warns in advance when Solaris runs low. Reolink's advice for shorter days is placement: face the panel south in the northern hemisphere, north in the southern.
Ring adds that "The seasonality and how far north or south you live will affect the strength of the sun." Reolink's blog goes further: a panel in shade in winter "can generate close to zero usable power". A camera with a large battery, or a panel you can move for the winter, is what gets through the dark months.
Where should the solar panel go?
In open, direct sun, facing the equator. Reolink, Ring and Blink all say to face the panel south in the northern hemisphere; Reolink and Ring warn against the shadow of trees, buildings and overhangs, and Reolink adds that its panel "cannot get power from indirect light such as LED light or moonlight".
Blink sells a 13-foot extension cable for its older Solar Panel Mount so the panel can sit in the sun while the camera stays where it is needed, and Ring's doorbell panel "Can be mounted anywhere on a wall or roof that gets direct sunlight". Reolink also says to clean the panel regularly; Blink to clear "debris, leaves, or snow". For a wider list of battery and solar cameras that record with no plan, see the outdoor page.
Does a solar camera still need a subscription?
A solar panel keeps the camera powered; it does nothing for the recording. A Ring or Blink camera on solar still needs its plan, or a Sync Module drive for Blink, to keep video. A camera that records to a card or a hub keeps it with no plan, sun or not.
That is the question this site answers brand by brand: Ring, Blink, eufy and Tapo, and all of them together on the roundup. Tapo's C465 has the panel built in and records to a card; eufy's S340 records to its HomeBase; Reolink's Argus 4 Pro takes an optional panel.

A camera with the panel built in, one with a removable panel and a HomeBase, and one that takes an optional panel. All three record locally with no subscription. Specifications as published by each maker, read 3 October 2026; nothing was tested.
