Hi
I have an idea for cleaning solar panels and I need to know if it's efficient or not.
I did some searches for common cleaning methods such as robots and manual cleaning, but didn't find much details so I can compare these methods to each other.
Where can I find more details to compare efficiency and cost?

 

The current meter on the solar panel system can tell you the comparison between cleaning methods, together with the invoices for each method used.
Unless you expected that someone else has already done the study for you without knowing your method.

 

Do they need cleaning?

Where can I find the current meter data for solar panels cleaned using each method?!

 

Perhaps on the display of the system ? If not, adding an ampere meter ?
