Importance of cleaning PV panels

Noticed my DHW temperature was not very high temperature and we have a couple days of clear skies, so should have been plenty of excess solar electricity.  So checked the PV output. Just over 1kW. Panels and roof covered a green film of pollen.

 

Out with soapy water and hose pipe and 10 mins later over 2.5kW.

We're getting paving done and now the whole area is covered in dust. Plus load sof pollen from the Scotts pines across the road. Filthy. Our panels are three stories up and no way to clean them and no rain forecast for two weeks.

Bit of a downer. I also looked at the gutter while I was there, so 10.mins cleaning panels, 30 mins cleaning gutter.
