This is an east-west (E-W) solar plant, and I’m wondering how to clean it properly. I don’t think I can do it with this brush (picture attached). Any suggestions?

Hi, I am Henry from South Africa, in the Overberg district. Done some solar cleaning jobs, did the ISCA training, but yes battle to get the South African mentality correct as people still believe rain alone is good enough for cleaning the panels. Hope to learn from you all.

Hi Solar Cleaners! I need your help. We are facing severe drought in Mauritius and the business is getting affected. I desperately need your help to come up with a solution to provide water for cleaning. (Dry cleaning is not effective in our very hot and humid island). Any technologies you know or might have heard that can recycle used water or convert sea water? Any idea is welcome. I look forward to hearing from you! Thank you

In modules that are connected in series, if one module fails, it can affect the entire string to which these modules are connected. But what happens if the modules have optimizers? Do they still impact the other modules that are connected in series? Example: If we have five modules connected in series, each with 400W power output, and one module fails, reducing its output to only 100W, then the "healthy" modules, which would normally operate at 400W, also drop to 100W. Does the same happen with modules that have optimizers?

Just a headsup that i've activated map location of all our members. You can now see where everybody is located 😉
