Get your solar panels working up to 25% more efficiently

Extend the lifespan of your panels and get them back to working at their best with our professional solar panel cleaning service.

A well-maintained Solar PV System can operate 25% more efficiently than one that is neglected

solar panel cleaning and maintenance using professional equipment

If you're not getting your solar panels professionally cleaned and maintained, they are likely to be working at only 75% of their optimum efficiency.

It’s a myth that solar panels can just be installed and then left for years to do their thing. Like any other technical home accessory, they need to be carefully maintained and looked after in order to keep working properly.

That’s where we come in. From as little as only £180, we can get your solar panels back to their best and working up to 25% more efficiently, within just 2 hours.

Benefits of regular solar panel cleaning & maintenance

Maximise energy production and efficiency

Regular maintenance ensures that your solar panels are clean and free from dust, dirt, debris, and any other obstructions that may hinder their efficiency. Clean panels can absorb more sunlight and produce more electricity, thereby maximizing their energy output.

Smarter, more aesthetically pleasing looking panels

No one likes to have anything on their property that looks messy and untidy, which is why we take care to make your solar panels look as good as new and enhance the overall appearance of your property as much as possible.

Extended lifespan of your panels and system

Proper maintenance helps identify and address potential issues early on, preventing them from developing into major problems. By fixing minor defects promptly, such as loose wiring or damaged components, you can extend the lifespan of your solar panels and avoid costly repairs or replacements.

Maximise overall safety of your installation

Solar panels involve electrical components, so safety is paramount. Regular maintenance includes inspections of the electrical connections, wiring, and other critical components to identify any hazards or potential risks. Addressing these issues promptly reduces the chances of electrical malfunctions, shocks, or fires.

Protect your investment in solar

Solar panel installations represent a significant financial investment. Regular maintenance helps protect this investment by ensuring that the system operates optimally and provides the expected return on investment. It minimises the risk of performance degradation, efficiency losses, or warranty voidance due to negligence.

Better performance monitoring

Maintenance visits often involve monitoring the performance of the solar panels. By analysing data on energy production, system efficiency, and other metrics, you can identify any deviations from expected performance levels. This allows you to take corrective actions if necessary, such as replacing underperforming panels or optimising system configuration.

Preserve your warranty coverage

Many solar panel manufacturers provide warranties that cover defects and performance issues for a specific period. However, these warranties often require regular maintenance as a condition. By adhering to the maintenance requirements, you ensure that your warranty remains valid and can take advantage of any potential repairs or replacements covered by the warranty.

Higher resale value for your solar panel system

Well-maintained solar panels can increase the resale value of your property. Prospective buyers are more likely to pay a premium for a home with a functional and efficient solar system. Much like a car MOT, evidence that you have maintained the solar panel system in your home will serve to increase the resale value of your property further.

Solar Panel Cleaning & Maintenance


Find the answer to your questions below.

Yes, cleaning solar panels can increase energy output by up to 30%. The removal of obstructions allows more sunlight to reach the photovoltaic cells.

Yes, regular cleaning can extend the lifespan of solar panels by preventing buildup that might cause long-term damage.

Cleaning frequency depends on the location and environmental conditions. In general, solar panels should be cleaned every 6 to 12 months. However, areas with heavy dust, pollen, or pollution may require more frequent cleaning.

Whilst solar panel systems are generally low maintenance, annual servicing is crucial to keep your panels clean, free from damage, and in optimal working condition. Regular maintenance also allows you to identify and fix any potential issues before they escalate. This will help save you from costly repairs further down the road and help ensure that your panels are generating the most energy possible.

Solar panels are known for their reliability, but like any technology, they can encounter their fair share of issues. It’s important to be aware of the potential problems your panels could experience, such as:


  • System failure due to poor quality installation
  • Damage from debris, wildlife, and inclement weather
  • Corrosion of panel surfaces and wiring
  • Problems with the inverter (which may have a shorter lifespan than the panels)
  • Solar battery malfunctions
  • A combination of any of the above factors

Solar systems are complex, so unless you’re a trained solar technician or engineer, you might struggle to identify and resolve any problems with your panels. That’s why we’re here to help!

You can clean the solar panels yourself using a soft brush or a gentle spray of water. However, if your solar array is installed in a hard-to-reach or high location, or if you’re uncomfortable doing it yourself, hiring a professional cleaning service is recommended.

Rainwater can wash away some dirt, but it may not be sufficient to maintain peak efficiency. Professional cleaning removes stubborn grime and improves performance.

The ideal time to clean solar panels is in the early morning or late afternoon when the panels are cool. Avoid cleaning them during peak sunlight hours, as water can evaporate quickly, leaving behind residues.

You can monitor your solar system’s performance through its monitoring software or inverter. A noticeable drop in energy production may indicate the need for cleaning.

No, cleaning your solar panels as per the manufacturer’s guidelines will not void the warranty. In fact, it may be a requirement to maintain warranty coverage.

Yes, after extreme weather events like dust storms or strong winds, it’s advisable to inspect and clean the solar panels to ensure they are operating optimally.

Yes, winter cleaning is essential, especially in snowy regions, as accumulated snow can significantly reduce energy production.

The extent of improvement depends on the initial level of dirt and shading. Cleaning can lead to efficiency gains of 10% or more, especially if the panels were heavily soiled.

No, harsh chemicals can damage the panels and should be avoided. Use only manufacturer-approved cleaning solutions.

Neglecting regular cleaning can lead to reduced energy production, decreased system efficiency, and potential long-term damage to the panels.
