That will be your custies 'misunderstanding' Doug - you're not to use cleaning solutions/chemicals on them but cleaning is obviously a very good idea if they want to maximise their feed in tariffs - clean vs dirty/dusty panels generate at least 1/3 more electricity (at least that's what google proved on their enormous arrays in the US used to power their server farms) 

It literally pays for itself to be reguarlly cleaned  - worth doing a little reading up on it - the cost/benefit analysis etc and explain it to your custy's so they get you back each year - I've got custies who get £2-3k back per year - they want their panels to be working optimally so they don't see a 'dip' in that return 👍

Thanks for the clarification. This makes total sense.

I’m testing a new product for lichen next week, approved by a pv manufacturer. Fingers crossed!!

Love to hear about it when you have tried it.

@solarpanelcleaningltd -  I'm guessing it must 'just' be a biocide? - is it really that much of an issue to warrant it's own product? I normally just get a few rosettes which quickly and easily lift off once soaked with pure/dwell/light scrub with WFP 🤔 Not sure i'd be in q  to pay for the product

I will be cleaning my panels later on today because we had rain all day yesterday and anything on them will be nice and soft. Hot pure water and I bump the pressure up to 70 and only takes me 5mins each side.

Just for solar panels but I use 60 when cleaning windows. Never got them cleaned, maybe Sunday, just too busy. Got a roof and pvc clean next week as well as a monoblock driveway fix. Still got 2 days of windows to clean and got asked to clean a conny today and maybe a new customer. Its all go at the moment, one job leads to another job. I have had 19 viewers on Checkatrade from Monday when I usually get 6 viewers in a full week. I hate being popular. 🤭

Depends if the computer measuring the power even still works? For them to show exactly the same post clean reading seems rare. Independent testing kit needed to be sure I imagine.

The readings are accurate , I have some very astute customers who keep an eye on output every hour of the day and they will keep  a record of kw produced  , sad but true 😬😂😬😂😬😂

At the beginning I used to keep a record of every day's readings till I ran out of ink. First year I got £1150 back but last year was £1500 back, so either its getting alot sunnier up hear or panels working better after the clean. The price did rise by about 15% though.

I think there's this happening, some deny it, but I've read about a thing called 'global warming' means even places like 'Scotaland' 😉 are getting more sun (less cloud) than ever before - year on year - might have a bearing🤔

Hope so, long may it continue but going by yesterday's rainfall who knows where its coming from now because I got caught in middle of it!
