Accumulated dust and debris on a solar panel

In order to function to its maximum efficiency, your solar panels need to be exposed to sunlight as much as possible. However, there are numerous factors that affect its performance such as system design, temperature, up to external or environmental factors like solar irradiance and soiling (also known as dust accumulation). What is solar soiling and how does it affect your system?


Solar soiling in a nutshell

Aside from how the system is designed, shading plays an important factor in your solar system’s efficiency. A small shaded part of your panels can contribute a lot to system loss. Normally, we only think about the big factors that can cause shadings, such as trees, vents, and nearby establishments, but we also need to watch out for the dust and grime that can accumulate on the panel’s surface over time. The accumulated dust and dirt particles on a solar panel are what is commonly referred to as solar soiling.

Numerous environmental factors can cause dust to accumulate such as volcanic eruption – like the recent Taal volcano activity, soil and salt deposition, and air pollution. The accumulated dust instigates the soiling effect. Soiling blocks the amount of light that your panels harvest which causes a drop in power production. Not only that, but soiling can also cause hot spots. Higher temperatures hamper power production, which can also cause energy losses and cell degradation over time. Expect that the reduced power output and losses in savings will continue until you get your solar panels cleaned.


Maintenance is key

Clean and maintained solar panels

A solar system does not require intricate and detailed maintenance. “For solar systems situated in places with everyday traffic such as EDSA or C5, frequent monitoring and cleaning is recommended,” says Mike De Guzman, President and CEO of Solaric Corp. “Dust intensity can vary from place to place. Cities in Metro Manila are of course more susceptible to pollution compared to the provinces, so the dirt and dust accumulate faster in the metro.”

Prolonged dust accumulation, accompanied by rain and humid weather, will cause the dust particles to harden – otherwise referred to as cementing, which makes it harder to remove. These cemented particles can become irremovable and cause permanent damage and deterioration in the solar module. Never underestimate these small particles as they could eventually cause big problems in the long run.
