Did you know that Australia is one of the leading countries in the world regarding the adoption of solar energy? It has the highest uptake of solar globally, with around 30% of homes with rooftop solar PV. The country has abundant sunshine, which makes it an ideal location for solar power generation. A home solar PV system installation costs thousands of dollars, but it pays its cost over time.
Thus, with increasing demand and mass production, many homeowners and businesses are gradually adopting the system! However, to maintain the efficiency and longevity of solar panels, it is essential to keep them clean. In this blog, we will explore the basics of solar panel cleaning in detail. Read on to find out more!
Do Solar Panels Need Cleaning?
Solar panels play a vital role in harnessing the power of the sun to generate clean and renewable energy. However, they can accumulate dirt, dust, pollen, bird droppings, and other debris over time. It raises an important question: do solar panels need cleaning? The answer is a resounding yes, and we’ll tell you why:
Maximising Energy Efficiency:
Clean solar panels operate at their maximum efficiency. Accumulated dirt and debris on the panels can block sunlight, reducing their ability to generate electricity. Regular cleaning ensures optimal sunlight absorption and energy production.
Maintaining Longevity:
Solar panels are a long-term investment; proper maintenance ensures longevity. Regular cleaning prevents the buildup of grime that can damage the surface of the panels and lead to costly repairs or replacements.
Enhancing Financial Returns:
Clean solar panels produce more energy, translating into greater financial returns. Removing dirt and debris maximises the electricity output and earns more through net metering or feed-in tariffs.
The Effect Of Neglecting Solar Panel Cleaning
While solar panels are durable and low-maintenance, neglecting their cleaning needs whether it be residential or commercial solar cleaning, it can have several adverse effects. Here’s a look at the potential consequences of not cleaning solar panels:
Reduced Energy Output:
The accumulated dirt, dust, and debris on solar panels create a barrier between the sun and the photovoltaic cells. It obstructs the absorption of sunlight and diminishes the panels’ energy-generating capacity. Over time, the lack of cleaning can significantly decrease the overall energy output of the solar system.
Decreased Efficiency:
Dirty solar panels operate at a lower efficiency level. The reduced sunlight penetration leads to a decrease in solar energy conversion into usable electricity. More panels might be required to achieve the desired energy production, resulting in additional costs and wasted potential.
Potential System Damage:
Neglected cleaning can accumulate stubborn dirt, grime, and bird droppings on solar panels. These elements can corrode the panel surfaces, causing long-term damage. If left unattended, the deterioration may require expensive repairs or even replacement of the affected panels.
