Does my location affect solar kilowatt-hour production potential?

Latitude and Sunlight Hours

The amount of sunlight a location receives is a crucial factor in determining solar kilowatt-hour production potential. As you move closer to the equator, the number of sunlight hours increases, resulting in higher energy production. For example, a location at 30°N latitude can receive around 2,500-2,800 kWh/m² per year, while a location at 60°N latitude can receive around 1,000-1,200 kWh/m² per year. This translates to a 20-30% increase in energy production between the two locations.

Panel Angle and Shading

The angle at which solar panels are installed also affects energy production. A panel installed at the optimal angle (usually between 20° and 40°) can increase energy production by 10-20% compared to a panel installed at a steeper angle. Additionally, shading from trees, buildings, or other structures can significantly reduce energy production. A 10% shading reduction can result in a 5-10% decrease in energy production.

System Design and Efficiency

A well-designed solar system can help maximize energy production potential. Using high-efficiency panels (15% or higher) can increase energy production by 10-20% compared to standard-efficiency panels. Additionally, using a microinverter or power optimizer can help to optimize energy production by up to 5-10%. By considering these factors, you can design a solar system that maximizes energy production potential based on your location and specific conditions.
