A common oversight is assuming that rainfall alone is sufficient to keep solar panels clean.

While it's true that rain can help wash away surface dust, dirt, or pollen, it's not quite effective against more stubborn residues like bird droppings. For those residing in regions where rain is infrequent or too gentle, a more hands-on approach to cleaning solar panels might be necessary.

The question often arises: "Does the accumulation of dirt and debris on solar panels significantly impact their efficiency?" The answer is nuanced. Indeed, these elements can hinder sunlight penetration and energy conversion, yet the efficiency reduction is generally minimal, often less than 5%. For a standard 5kW solar setup, this could translate to a mere $20 reduction in energy costs over time, not per month. In dry areas, eventual rainfall might cleanse the panels after months, suggesting that immediate cleaning might not always justify the effort. However, it's wise to regularly review your energy bills and system performance. Noticing a spike in your electricity expenses could signal the need for cleaning or maintenance.
