Areas that receive abundant sunlight year-round can generate more kWh per panel compared to regions with frequent cloud cover or shorter daylight hours. For instance, solar panels installed in sunny states like California or Arizona can expect higher energy outputs than those in cloudy locations like the Pacific Northwest.
