After trying and failing they decided to heed my advice and give Celtic Cleaner a call. They came out at the last minute and did an amazing job! Their customer service is the best in the industry!"

Solar Panel Cleaning

Did you know you must clean your solar panels to order to maximize efficiency?

If you are reading this section, you have likely invested in a clean solar energy setup, playing your part in protecting our planet so that our children and our children’s children can go on to enjoy it!

You have also conducted some smart business, knowing that the money you have spent is really an investment and that you will save money in the long run. But if your solar panels are unkept and dirty, they're not saving you as much money as they could.

At Celtic Window Cleaning we provide an effective method of cleaning solar panels — saving you the danger of cleaning them yourself! Request a free quotation via one of the buttons below:

About The Owner

Richard was raised in the northeast of Scotland in the fair town of Banff. His love affair with window cleaning really started in London, where he mastered the skill while working for The London Window Cleaner. His former employers shine windows for the likes of Marriott hotels, the Victoria and Albert and British museums, and even Buckingham Palace!
In 2014 Richard married and relocated to Bellingham, where he embarked on his own window cleaning business, Celtic Window Cleaning. When not cleaning windows, Richard enjoys cycling, rugby, playing guitar, cooking, sampling our local breweries and talking about Scotland, Scottish culture and scotch!
