How Many Peak Sun Hours in Arkansas?

SBI Editorial DeskUpdated Q1 · 20262 sections

Many homeowners worry about cloud cover, but solar engineers measure viability in "peak sun hours"—the specific times when solar intensity reaches 1,000 watts per square meter.

01

The Natural State Solar Reality

Arkansas is an excellent state for solar generation, receiving an average of 4.5 to 5 peak sun hours per day. This high level of solar irradiance is more than enough to offset a significant portion, if not 100%, of a home's electricity usage when the system is correctly designed.

02

Maximizing the Net Metering Cycle

During the long, intense days of July and August, your panels will vastly overproduce. Thanks to net metering laws, this excess summer power is credited to your account and helps cover your electricity needs during the shorter days of winter.
