Witham Group, one of the UK’s leading independent lubricant and paint manufacturers, has announced the launch of Qualube SolaBright, a new, specially formulated cleaning solution, designed to maintain the efficiency and longevity of solar panels. This new product arrives as the UK sees a significant surge in solar energy adoption.

The Growing Need for Solar Panel Maintenance
The UK has experienced substantial growth in solar panel installations, with a 6.6% rise in solar capacity since January 2023, reaching 15.7 GW across 1.4 million installations as of January 2025. This expansion reflects a nationwide push towards renewable energy, further bolstered by fresh government policy commitments aiming to triple the UK’s solar capacity by 2030.
However, the efficiency of these solar panels can be significantly reduced by the build-up of dirt, lichen, dust, debris, and other contaminants. These substances block sunlight from reaching the photovoltaic cells, leading to a decrease in electricity production. Regular cleaning is crucial, with studies indicating that it can boost solar panel efficiency by up to 20%.

Introducing Qualube SolaBright
To address this growing need, Witham Group has developed Qualube SolaBright. This carefully formulated cleaning solution effectively removes common culprits such as lichen, mould, dirt, grime, and bird droppings without causing damage to the delicate surface of the panels.
Qualube SolaBright is a pH neutral, low-foaming detergent ideal for all types of domestic and commercial solar panels. It is now available in 5-litre and 25-litre containers and can be found in the cleaning products section of Witham Group’s website.
This new addition to Witham Group’s cleaning range underscores the company’s commitment to supporting the UK’s transition to a greener future by providing effective solutions for maintaining renewable energy infrastructure.
Already Receiving Great Reviews!
A recent customer review for Qualube SolaBright:
“We have a 250kW/hr solar power generation site with 960 ground mounted panels. This was installed in 2015. Dirty panels can reduce power generation and therefor income by up to 20% so it is essential to clean them effectively and efficiently at least twice per year. Over the years I have tried various different cleaning products, usually detergent based to work with different brush types. We settled on a power driven brush in 2024 and initially used a TFR product but this didn’t loosen the lichen spots. We then tried a solar panel cleaner which was more successful. In July 2024 and since we have been using Witham SolaBright Panel cleaner and this is the best yet! Sprayed on from a pressure washer lance and left to soak into the dirt, grime, bird droppings and lichen for approximately ten minutes, followed by the power brush and an excellent result is achieved.”
