Cleaning and electrical testing – ground mounted 200kW

Our cleaning and maintenance division are uniquely equipped to deal with any PV issue that you may be experiencing.  Armed with state of the art cleaning brushes, pumps and chemical treatments, along with their own dedicated access lift we offer a first-class service that is competitively priced.

DSC_0471We operate and maintain many hundreds of sites across the UK and Europe and our customers come to us year after year – with a large proportion of our new sites coming from recommendations rather than advertising.

We take pride in our work and take all steps necessary to ensure that you get the most you possibly can from your PV installation.

Generally that will simply mean keeping it clean and undertaking electrical testing once a year, although it may involve all sorts of other functions, ranging from lichen removal, to inverter replacement to detailed monitoring and fault-finding.

In this case, our electrical testing identified that one inverter had failed and did indeed need to be replaced.  This is surprisingly common given the number of inverters being installed, so it is absolutely essential that it is noticed while the equipment is still under warranty.  Otherwise the cost of a new unit will run into the thousands.
