☀️ Solar Hour Power, often referred to as Peak Sun Hours, is a key concept in solar energy that helps determine how much electricity a solar panel can generate in a day. It’s not just about how long the sun is out—it’s about how strong the sunlight is
-
A Peak Sun Hour is one hour of sunlight that delivers 1,000 watts per square meter.
-
It’s a way to measure the intensity of sunlight, not just the duration.
-
For example, 5 peak sun hours means your solar panels receive the equivalent of 5 hours of full-strength sunlight.
- Daily Energy Output = 300W × 5 hours × 0.75 / 1000 = 1.125 kWh/day
-
Arizona, USA: ~7 peak sun hours/day
-
Bengaluru, India: ~5.5–6 peak sun hours/day
-
London, UK: ~2.5–3.5 peak sun hours/day
