How to Increase Solar Panel Efficiency?

A solar system's efficiency depends not only on panel quality but also on installation details and maintenance habits. This article covers the factors that directly affect panel performance.

Panel Angle and Orientation

The angle and orientation of panels relative to the sun directly affects how much sunlight they receive. For most of Turkey, south-facing panels tilted to match the region's latitude typically deliver the highest annual output. Getting the angle/orientation right before installation is a decision that affects efficiency for the system's entire lifetime.

Shading

Partial shading from building overhangs, chimneys, trees, or neighboring structures can noticeably reduce output at the panel or string level. A shading analysis during the site survey is important for correctly positioning panels.

Temperature Effects

Solar panels can lose some efficiency at high temperatures. Mounting systems that allow airflow beneath the panels help mitigate this effect.

Regular Cleaning and Maintenance

Dust, pollen, bird droppings, or dirt buildup can reduce the light reaching the panel surface and lower output. Periodic cleaning, scheduled according to the region's dust/pollution levels, helps maintain the system's long-term efficiency.
