FAQs

Dirty solar panels can significantly reduce their efficiency by blocking sunlight and decreasing energy output. Regular cleaning ensures your panels perform at their best, maximises your energy savings, and prolongs the life of your solar system.

The frequency of cleaning depends on your location and environmental factors. Generally, we recommend cleaning your Residential panels every 1 year. However, for Commercial use or if you live in areas with high dust, pollution, bird activity, or near trees, twice a year or more frequent cleaning may be necessary.
While rain may wash off some surface dirt, it is not sufficient to remove stubborn grime, bird droppings, or mineral buildup. Professional cleaning ensures a thorough clean that rain alone cannot provide.
At Ultimate Solar Care, we use eco-friendly methods such as deionised water and reverse osmosis technology. These systems remove all impurities, ensuring a spotless clean without leaving streaks, spots, or residue. We avoid harsh chemicals to protect your panels and the environment.

The duration of a cleaning session depends on the size of your solar system and the level of dirt. On average, residential cleanings take about 1-2 hours, while commercial systems may take longer.

If you notice a drop in your energy output or see visible dirt, grime, or bird droppings on your panels, it’s time for a cleaning. Regular inspections can help you identify when professional cleaning is needed.
