“I was first introduced to Optisol in 2016 where we required panel cleaning on a few of our solar farms. Although we had left it until late into the summer, Jack and the team were able to be accommodating and make space to carry out the works, working mainly over the weekends. After completion of the works, inspections were carried out where the quality was second to none, no issues arose from any part of the planning, issuing of safety documents to cleaning, a true professional outfit. 

Since our initial meet RES have used Optisol in other areas of the business, from ground works to lifting, no job is unable to be completed by Jack and his team, and true to form, was carried out to the upmost professionalism. 

I would have no issues with further recommending Jack and Optisol to any other business, their ability to carry out work along with their business ethics, are something which we as a company are pleased to be associated with.”

“I meant what I said about the high quality photovoltaic panel cleaning you carry out. 


Over the last 10yrs I have been involved with solar farm construction, operation & maintenance and now, asset management. I have seen at least 6 different companies claiming to do similar work to you, but none, and I mean NONE of them come close to your professionalism, dedication and attention to detail.


It was obvious to me that you and your team don’t just want to splash some water over the panels and get off site as quickly as possible, you guys actually want to do a quality job, clean the panels and leave the site in a better state than you found it.


You should be proud of the work you do and the service you offer. Based on what I saw you doing and the fantastic end result, I would not hesitate to recommend you and your company for future contracts.”

Mark Harding-Rolls - Head of O&M Service Delivery

“This will be the third year we have contracted Optisol to panel clean (mechanically and by hand) the solar parks we are responsible for.


Despite the geographical challenges and contractual requirements demanded by owners, the service they provide is excellent and always delivered to a very high standard.


Their experienced and very competent operators are trusted to conduct all works on site in a safe and controlled manner.


Communication is good, they are always on time, very flexible and reliable.


BSR has therefore got every intention of remaining in contract with them and are very grateful for the excellent service they provide.”

“I can honestly say, it has been my pleasure to work with Optisol, your attention to detail surpassed my expectations.”

Robert Paine – O&M Service Manager UK

“Sam and his team have been extremely reliable contractors, cleaning 46MW solar portfolio spread across 7 UK sites, who we would have no hesitation in using again. They were very professional in their approach, providing a quick turnaround on relevant method statements, safety information and pricing estimates. Where necessary Sam was completely transparent in managing both ours and the owners expectations, and went above and beyond to work around a tight inspection schedule at very short notice. Again, we will certainly be using Optisol Services for future projects given the competitive price and quality of the work.”
