Solar Camera Sun Hours in Fayetteville, Arkansas: Winter Guide

Q: What angle should I mount the panel at in Fayetteville?

Roughly 51 degrees from horizontal, facing south in the US, using the rule of thumb of latitude plus about 15 degrees. It is an estimate.

Good sun all year

Fayetteville gets good sun all year. Even December, the dimmest month, averages 2.14 peak sun hours a day, which is usually enough for a low-power solar camera.

Average peak sun hours per day, from NASA's 25-year monthly climatology. A peak sun hour is one hour of full-strength sunlight (1,000 W per square metre) on a flat surface. The dashed 2-hour line is a planning guide, not a hard limit: below it, a 5 W panel collects under about 7.5 Wh a day by our estimate, so the battery has to cover more of the camera's use.

Monthly figures and 5 W panel estimate

January	2.47	9.26
February	3.06	11.47
March	4.08	15.30
April	5.15	19.31
May	5.75	21.56
June	6.66	24.98

November	2.71	10.16
December	2.14	8.03

Panel estimate = 5 W × peak sun hours × 0.75. The 0.75 allows for real-world losses such as panel angle, heat, dust and charging. It is a planning figure, not a guarantee, and a camera's own panel may be rated higher or lower than 5 W.

What this means for a solar or 4G camera in Fayetteville

Sunlight is one important factor, alongside the camera's battery size, how much power it uses, cold and shade. June has about 3.1 times the sun of December. No month falls below 2 peak sun hours.

Compare these with the camera's daily power use, the energy it uses in a typical day, in Wh. Few listings give it directly; some give a typical runtime instead, which you can turn into daily use by dividing the battery's stored energy by the number of days it lasts.

Battery capacity is different: it is stored energy, not daily use. A 10,000 mAh battery at 3.7 V holds 10,000 × 3.7 ÷ 1,000 = 37 Wh. That tells you how long the camera can run when the panel falls short, not how much it needs each day. If daily use is higher than what the panel collects, the battery covers the gap until it runs low.

Even in December a 5 W panel collects about 8.03 Wh a day by our estimate. Compare that with your camera's daily use; shade is usually a bigger risk here than the season.
Tilt the panel about 51° toward the equator and keep it clear of branches and eaves.
Dust, pollen and heat haze trim output, so wipe the panel a couple of times a year.
Longer clips and higher-quality recording settings use more power. With more sun to work with, you may have room for them, but check the camera's battery life figures first.

About the panel angle: 51° is your latitude (about 36°) plus roughly 15°, a common rule of thumb for getting the most from low winter sun. It is an estimate, and the best angle for your spot depends on shade and how the panel mounts.

Check a camera against Fayetteville's winter

Before you buy, look for these on the product page or in the manual:

Daily power use. Compare it with the 8.03 Wh a day a 5 W panel collects here in December. Don't compare the battery's capacity with this number: capacity tells you how many days of reserve you have, not what the camera uses.
Panel size. A bigger panel, or one you can mount away from the camera in full sun, gives you more margin.
Charging temperature. Check the camera's rated operating and charging temperatures.
Connection. Wi-Fi models need your router in range; 4G models need mobile coverage and a data plan.

Common questions

Will a solar security camera work in Fayetteville in winter?

Usually, yes. Even in December the average is 2.14 peak sun hours, so a low-power solar camera should keep charging. The camera's power use, battery size, shade, snow on the panel and panel angle all matter as much as the city average.

What angle should I mount the panel at in Fayetteville?

A common rule of thumb for the dim months is latitude plus about 15 degrees. For Fayetteville that is roughly 51° from horizontal, facing south in the US. It is an estimate; a steeper angle also helps snow slide off.

How did you work these numbers out?

We took NASA POWER's monthly climatology of all-sky solar irradiance on a horizontal surface (parameter ALLSKY_SFC_SW_DWN, 25-year average, 2001 to 2025) at Fayetteville's coordinates (36.07, -94.17). That value, in kWh per square metre per day, equals peak sun hours. The 5 W panel figure is 5 × peak sun hours × 0.75, and the rank sorts all 249 places by their dimmest month.

Do I need Wi-Fi?

No. A 4G camera uses a mobile data plan instead, which suits places without Wi-Fi. Check coverage at your property before buying, and note that a data plan is an extra running cost.
