Solar Panels Cleaning

Solar panels are increasingly popular among building owners seeking to reduce energy costs and support sustainability goals. However, maintaining optimal energy production requires more than installation; regular upkeep is necessary to keep panels functioning efficiently.

One aspect of effective maintenance is cleaning to prevent the build-up of debris and pollutants that can reduce performance over time. Universal Tankers provides water deliveries tailored for solar panel cleaning, offering a reliable source of purified water as an efficient panel cleaner to help maintain the energy generation capabilities of your photovoltaic (PV) system.

For sites without access to a mains water supply, Universal Tankers can arrange solar panels cleaning through trusted third parties. By coordinating with professional cleaning providers, we help ensure that panels are properly maintained, even in remote or challenging locations. This solution is designed to give building owners access to the resources needed for effective panel maintenance, regardless of site constraints.

What factors affect solar panels’ cleaning needs?

Solar panels are designed to efficiently harness sunlight, but their performance can be impacted by environmental factors. Over time, they accumulate dust, bird droppings, pollen and other pollutants, forming a layer of grime that reduces sunlight reaching the photovoltaic cells, lowering energy output. Studies suggest energy production can decrease by as much as 7% annually due to dirt accumulation, with local conditions influencing the extent. For instance:

  • Urban areas may experience higher pollution levels, leading to fine particulate deposits on panels.
  • Rural and agricultural areas often encounter dust and organic material build-up.
  • Coastal locations may face salt residue from sea spray, which can be corrosive.

With these conditions in mind, maintaining a regular cleaning routine with appropriate equipment and water is essential to keeping solar panels in optimal condition.

Benefits of solar panel cleaning

Universal Tankers’ water delivery services support the cleaning of solar panels, providing access to purified water that enhances the efficiency and longevity of solar installations.

  • Enhanced efficiency: clean panels are more effective at capturing sunlight, supporting consistent energy production. Regular cleaning reduces energy waste, enabling building owners to maximise their return on investment. Consistently clean panels produce higher energy output, contributing to greater energy savings.
  • Prevention of damage: dirt left on panels can cause "hotspots," where sections overheat, reducing system efficiency and potentially causing structural damage. Regular cleaning helps mitigate this risk, protecting the integrity of the system and reducing the likelihood of costly repairs.
  • Cost-effectiveness: using purified water for regular cleaning extends the lifespan of panels and helps maintain their efficiency. Clean panels generate more energy, reducing energy costs and minimising the financial impact of inefficiency or repairs caused by dirt accumulation.
  • Warranty compliance: many solar panel warranties specify regular maintenance to remain valid. Neglecting cleaning or allowing grime to build up can void these warranties. Access to reliable water deliveries ensures panels are maintained according to manufacturer conditions, preserving warranty coverage and safeguarding the investment.

How often should solar panels be cleaned?

The timing of cleaning varies based on location and environmental factors. Regular cleaning tailored to your solar PV system’s needs can optimise its efficiency and long-term performance.

  • Frequency recommendations: cleaning intervals depend on location and environmental conditions. For most sites, cleaning every six to twelve months supports consistent energy production. In areas with higher pollution, frequent bird activity, or agricultural dust, more frequent cleaning may be necessary to avoid debris build-up. Universal Tankers can supply purified water as part of a plan tailored to your site’s needs. For locations without a mains water supply, we can coordinate cleaning through professional third-party providers.
  • Monitoring output: declines in energy production may indicate the need for cleaning. Access to timely water deliveries and reliable cleaning services can help you address performance concerns efficiently, keeping panels in good condition.
