I suppose what everyone would be interested to hear though is "did the output increase".

Well I have gained almost 2 solar panels out of it, Or about 400W, If thats an appropriate way to say it, everyone has different panels.
Haven't had really good sunny day since cleaning them.
The glass felt like sandpaper before cleaning them. ;)

What I meant was has the number of kWh per day increased. Do you have any monitoring ?
I suppose if they get that dirty then its good to do regular cleaning anyway - before the dirt builds up so much its impossible to remove or causes damage.

Hi Benny
Its an off grid shed, so I have no need for any KWH monitoring, it Just sits idle most of the day until the HWS starts and I use a few power tools, most often use more power than the panels can put in, the charge controller registers a higher output thats how I see bit better performance after cleaning.

unless you need exercise and are bored and the panels are really dirty, don't worry about cleaning. there are more threads on this forum about it.
