Maintenance requirement

As part of a commercial solar PV maintenance contract in London, DW Energy carried out routine system testing and professional panel cleaning.

Dirt and grime can restrict solar performance over time, making regular inspection and cleaning important for maintaining the system and meeting any manufacturer-specific maintenance requirements.

Testing and cleaning

Our engineers tested the PV system before thoroughly cleaning the solar panels and checking their condition.

Measured results

Testing following the maintenance work recorded an immediate improvement across both strings:

String 1: voltage increased by 9.2 V
String 2: voltage increased by 11.6 V

The results demonstrate how planned solar maintenance can help commercial systems continue operating effectively.
