While the specific frequency of solar company inspections may vary depending on factors such as weather and local conditions, it is generally recommended to inspect your solar panels at least once a year.

However, if you live in an area with heavy pollution, frequent dust storms, or high levels of bird activity, you may need to increase the annual inspection frequency.

When it comes to pollution, areas with high levels of air pollution can cause a build-up of dirt and grime on the surface of solar panels. This can reduce their efficiency and overall performance.

Regular inspections can help identify any dirt or pollution build-up, and prompt you to clean your solar panels for optimal efficiency.

Dust Storms

In regions prone to frequent dust storms, the panels are more likely to accumulate a layer of dust and debris. This can hinder the sun’s rays’ absorption of sunlight and reduce the panels’ electricity output amount. By increasing the frequency of inspections, you can promptly address any dust accumulation and ensure solar panels require maximum efficiency and energy production.

Bird Activity

For areas with high bird activity, inspections become even more crucial. Birds can leave droppings on the panels, which not only affect their efficiency but can also lead to potential damage if left unattended.

Regular inspections allow for the identification and removal of any bird droppings, preventing long-term issues and maintaining the high quality solar panels’ performance.
