You certainly won’t damage them with a brush unless doing something way out of the ordinary , if the panels need cleaning monthly or annualy just clean as required by the customer , we used to do some arrays every three months , but I hated doing them so gave the contract up

Ok thanks. Appreciate it

I've nothing to support this but my intuition but I would have thought that cleaning more frequently (and using less water or scrubbing than you would say six monthly or yearly) would mean less chance of water ingress or sealant damage.

But I would probably ask for a waiver if it was anything beyond an occasional domestic clean.

Iam going to do them. 6 monthly or a year.  To be safe. And a high flow rate. Possibly.   70. To 80. On the  box.  Thanks
