Did you know?
High-pressure washing is one of the most common causes of damage to commercial solar PV systems.
Excessive pressure can compromise the seals between the solar glass and aluminium frame. Over time, this allows moisture ingress, which may lead to grounding faults, reduced output, or premature system failure. In some cases, it can also invalidate manufacturer warranties.
That’s why professional solar cleaning is not about force. It’s about trained assessment, correct methodology, and working in line with manufacturer guidance and electrical safety standards. At Lowen Cleaning, we use controlled, low-pressure techniques designed specifically for live commercial environments.
If you’re responsible for a site with solar PV, it’s worth checking how it’s being cleaned.
