Frequently Asked Questions
FAQs
Why should I clean my solar panels?
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.
How often should I clean my solar panels?
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.
Can’t rainwater clean my solar panels?
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.
What methods do you use to clean solar panels?
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.
How long does a cleaning session take?
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.
How do I know if my panels need cleaning?
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.
