RV Solar by State: Sun Hours and Sizing Compared
The same solar system produces very different results in Arizona than in a shaded forest campground, because daily harvest follows local sun hours.
These state guides show the typical solar resource, the regions where RVers run on panel power, and what to plan for.

Sun Hours Compared
The eight states side by side, sorted by solar resource.
Pick Your State
Sun hour figures on each page are approximate averages based on published NREL solar resource data.
Arizona
Arizona offers some of the best solar conditions in the country for RVs. See typical sun hours, how to size a system for desert boondocking, and what to plan for.
California
California spans desert sun and foggy coastline, so RV solar sizing depends on where you camp. See typical sun hours by region and how to plan a system.
Texas
Texas runs from humid Gulf Coast to high desert, and RV solar output follows. See typical sun hours across the state and how to size a system that keeps up.
Florida
Florida sun is strong but comes with humidity, storms, and shade. See typical sun hours, how snowbirds size RV solar, and what to plan for in the Sunshine State.
Nevada
Nevada pairs a top tier solar resource with vast public land. See typical sun hours, how to size for high desert boondocking, and what to plan for.
New Mexico
New Mexico combines a top tier solar resource with high desert camping. See typical sun hours, sizing guidance, and what to plan for in the Land of Enchantment.
Colorado
Colorado mixes intense high altitude sun with mountain shade and snow. See typical sun hours, how to size RV solar for the Rockies, and what to plan for.
Utah
Utah pairs red rock boondocking with a strong solar resource. See typical sun hours, how to size a system for the canyon country, and what to plan for.
Turn Sun Hours Into a System Size
Daily harvest is roughly panel watts multiplied by local sun hours, minus real world losses.

Common Questions
Why do sun hours matter for RV solar sizing?
A peak sun hour is a full hour of standardized strong sunlight, and your daily harvest is roughly panel watts multiplied by local sun hours. The same 400 watt array collects noticeably more energy per day in Arizona than in a cloudy or shaded region, so where you camp changes how much panel you need.
Which state is best for RV solar?
The desert Southwest leads the country. Arizona and New Mexico average roughly 5.5 to 6.5 peak sun hours per day based on published NREL solar resource data, with Nevada close behind, which is why the winter boondocking crowd concentrates there.
Do these pages tell me my exact production?
No. The figures are approximate statewide averages from published NREL solar resource data. Season, weather, shade, panel angle, and temperature all move real world output, so treat the ranges as planning inputs rather than guarantees.
