The care of solar panels is key because dirt and pollutants can cut their efficiency. In India, with its fast growth of solar use, keeping panels clean is crucial for everyone.

Dust on solar panels can cut their power by up to 30 percent in a month. This can have big financial impacts. For instance, if a 150-megawatt solar plant produces 1 percent less energy, it could lose over INR 15 crores a year. These facts show that good cleaning can boost energy production, not just new tech.

Cleaning solar panels needs a lot of water, around 10 billion gallons a year. This method is expensive and uses a precious resource. But, new waterless cleaning systems may change this. They can clean more often, cost less, and work well even in very humid places like much of India.

Using these new cleaning methods helps meet global goals to cut carbon dioxide emissions. To hit these goals, renewable energy must grow 12 percent each year until 2030. Better solar panel care, including smart cleaning systems that use rainwater, will be important.

In dry places, dust can make solar panels half as efficient. In the Middle East, dust can cause losses between 10 percent to 70 percent. Using automated cleaning systems could greatly reduce these losses. This highlights how vital clean solar panels are.

  • Renewable energy was about 29% of global power in 2020, growing 2% per year.
  • The most advanced solar cells are now 31% efficient.
  • According to Smestad et al. (2020), dust can lower yearly revenue by 4% per panel. This costs about INR 8,000 per panel each year in India.

Fenice Energy, with over 20 years in clean energy, says regular solar panel cleaning is key. It boosts energy and is a main part of solar panel maintenance. This keeps your renewable energy investment safe for the future.
