Good communication, professional, and completed quickly. The job ended up being bigger than the quote based on the initial inspection, but the price was fair. Would use again.

We are Solar Technicians. Not pest control experts or window cleaners. We have the knowledge and experience when it involves installing or maintaining your Solar Panels. You wouldn’t want a brick layer working of your solar panels, would you? All our work comes with a Workmanship Guarantee and we are covered by our Public liability insurance. We do not use any chemicals or treatment to clean the solar panels and our specialist equipment protects the ARC on the face of the solar panels. Using the wrong equipment could be detrimental to your solar panels. We only use the highest standard of materials for Solar Bird Protection and the correct equipment for carrying out Solar Panel Cleans. Hence why pest control experts stuff chicken wire under the Solar Panels & window cleaners get poor results when they attempt to clean the Solar Panels from the ground with a soft bristle brush. We will be gaining access to the roof without scaffolding, which keeps the cost down and also using the correct equipment to clean the panles that will remove the build up of Lichen, Algae & any pollen / dust whilst still protecting the ARC on the face of the solar panels. We would advise a solar clean once a year, anymore is not necessary. If you wish to have both services completed at the same time, we would be happy to offer a discount. Please feel free to read our reviews on Google, for your own peace of mind of the quality service we provide.

Kevin quoted and did the job. Very polite and helpful. Job done a few days ago, 1 or 2 pigeons still hanging around which was what Kevin said but no bird mess on the paving since he did the job which is a very good sign to indicate what Kevin done is working as there was always bird mess in the morning that needed cleaning. Top professional 5 stars to Kevin. Would definitely recommend Kevin to anyone who has issues with pigeons nesting and sheltering under solar panels
