On the subject of solar panels, it always occurred to me...
I nearly had mine done maybe 15 years ago and got cold feet. Iirc after 20 or 25 years, they become your responsibility and that bugged me, what are you going to do then, have to pay to get them repaired, replaced, removed ? A bit short sighted I admit but it is a relevent point.
And then I look across the road to people that had theirs done maybe 5 to 10 years ago...covered in mildew or lichen. Their efficiency must be down 30%
It's not all black and white, it's not all win win.
I just get out a bucket of water and my extension poles and give them a clean. Takes about 20 mins.
The Eco washing up liquid is quite expensive though and may run out one day despite buying 5 litres.
