Cleaning your solar panels is one of the simplest methods of making sure your investment works out. Dirt, dust, and bird droppings may not appear to be a major problem, but these elements can reduce its efficiency, because they may obscure sunlight. This will reduce your power output and raise your electricity bill in the long run. As the energy demand grows, the cleaning of solar panels cannot be ignored by homeowners and businesses.
Feroze Power takes you through the ins and outs of solar panel cleaning, including the reasons why and how frequently you need to clean the panels.
Why Solar Panel Cleaning Matters
To produce maximum energy, solar panels require direct sunlight. A dusty coating, even thin, is capable of blocking rays and diminishing performance. Research has revealed that dirty panels may lose 15- 25 percent of their output. Maintaining solar cleaning would keep your system providing the same amount of results and would save you more in the long run.

How Often Should You Clean Solar Panels?
It depends on where you live. Depending on your location, dust storms, rain, or bird population might mean that you have to clean panels more frequently. Usually, the professionals suggest once every two years. To maintain the performance at its best levels, some households even clean quarterly.
Best Methods for Solar Cleaning in 2025
There are multiple approaches to how to clean solar panels:
- Washing with water: Effective on light dust.
- Soft sponges and brushes: These can be used when there is hard dirt.
- Green products: Soft detergents which will not break the glass.
- Automated cleaning systems: Becoming popular in 2025 on large rooftops.

Tools and Products You Can Use
The correct equipment makes a huge difference. Homeowners often use:
- Brushes with soft bristles that are extendable.
- Spray-attached garden hoses.
- Streak-free drying squeegees.
High-pressure washers and harsh chemicals should be avoided, as they can damage the panels.
Professional vs DIY: What’s Better?
DIY is effective when you have a small house and are confident about your safety and tools. Nevertheless, professional services will provide more extensive cleaning and may include inspections for damage. The professionals provide superior value in large installations by preventing costly breakdowns.
Safety Tips for Cleaning Solar Panels
Safety should always come first:
- Avoid cleaning during peak sunlight hours to prevent burns.
- Use non-slip ladders and safety harnesses for rooftop work.
- Turn off your solar power system before starting.
Costs of Solar Panel Cleaning
On average, cleaning costs depend on size and accessibility:
- Residential systems (≈ 10 kW) ~ PKR 3,000 to PKR 5,000
- Small systems in housing (up to ~3-6 kW) ~ PKR 1,500 to PKR 3,000 depending on access
- Medium-large rooftop systems (7-10 kW) ~ PKR 6,500 to PKR 9,500
Regular cleaning is an affordable way to protect your investment.
Future of Solar Cleaning Technology
Due to the prevalence of renewable energy, maintenance has also become more innovative. In 2025, we’re seeing the rise of:
- Minimal water-consuming cleaning robots.
- Self-cleaning coatings that repel dust
- AI-driven monitoring tools that signal when cleaning is required
