As a renewable energy expert with a focus on solar technology, I've had the opportunity to work with various solar panel installations across different environments. It's an interesting question about the maintenance of solar panels, especially regarding the need for cleaning.
Solar panels are indeed designed to be relatively self-cleaning due to their smooth surface, which is meant to shed water and debris naturally. However, there are several factors that can affect the efficiency of this self-cleaning process. The accumulation of dust, dirt, bird droppings, and other organic matter can significantly reduce the amount of sunlight that reaches the photovoltaic cells, thereby impacting the electricity generation capability of the panels.
In particularly dry regions, where there is less rainfall to wash away the dust, or in areas with minimal panel tilt, where gravity is less effective at removing debris, the buildup can be more problematic. Even a small amount of grime or bird droppings can have a noticeable effect on a panel's performance. It's important to note that this effect is not uniform; the impact on electricity generation can vary depending on the location and concentration of the dirt.
The frequency of cleaning needed can depend on the specific conditions of the installation. For instance, panels in urban areas may require more frequent cleaning due to higher levels of air pollution, while those in rural areas might need less attention. Additionally, the angle at which the panels are installed can play a role in how often they need to be cleaned. Panels installed at a steeper angle are more likely to shed water and debris more effectively.
When it comes to cleaning solar panels, it's recommended to use a soft brush or cloth to avoid scratching the surface, and to use water that is not too pressurized to prevent damage to the cells. It's also important to clean the panels during the early morning or late afternoon to avoid the risk of the panels overheating from direct sunlight while wet.
In conclusion, while solar panels are designed to be self-cleaning, environmental factors and the specific conditions of the installation can necessitate periodic cleaning to maintain optimal performance. Regular inspection and maintenance are key to ensuring that your solar panels continue to generate electricity efficiently.

Solar panels are generally self cleaning, but in particularly dry areas or where panel tilt is minimal, dust and other substances such as bird droppings can build up over time and impact on the amount electricity generated by a module. Grime and bird poop doesn't need to cover an entire panel to have an effect.
