Technical FAQs 4

Should solar panels face east or west?

Solar panels that face east or west will produce about 15% less energy than those installed on a south-facing roof. A north-facing roof is the worst direction for solar, as panels will produce around 30% less energy than if they face south.

How much solar energy does a south facing roof generate?

According to data from the U.S. Energy Information Administration (EIA), solar panels on roofs that are tilted 20% to the west from true south will still generate 89% of what a southern-facing roof will. Panels on roofs that face 20% east will generate 85% of those on a roof that’s oriented south.

Why do solar panels face south?

Homeowners and businesses benefit from higher energy production, increased savings on electricity bills, and a more sustainable and environmentally friendly energy source, making the investment in solar panels facing south highly rewarding. Explore why solar panels face south for optimal sun exposure.

Why do solar panels have a south-facing orientation?

A south-facing orientation ensures that all panels in the array receive sunlight evenly, allowing for a consistent output across the entire system. While south-facing orientation is optimal for year-round sun exposure, it is not the only factor to consider.
