Summary: Wondering how much energy a solar panel can generate? This guide breaks down photovoltaic panel output, explores efficiency factors like sunlight and temperature, and shares real-world data to help you calculate energy production for homes or businesses.

What Determines a Solar Panel''s Power Output?

While most residential photovoltaic panels are labeled as 300-400 watts, actual energy production depends on three key factors:

• Sunlight intensity: Output drops by 0.3%-0.5% for every 1°C temperature increase above 25°C
• Panel orientation: South-facing (in the Northern Hemisphere) panels yield 15-25% more energy than east/west setups
• System losses: Inverters and wiring typically cause 3-10% energy loss

"Think of panel efficiency like a car''s fuel economy – both tell you how well a system converts raw resources (sunlight/gasoline) into usable energy."
