Hello guys. What do you answer to the eternal question -why shouldn't I let the rain wash my panels?

Hi guys! In a Facebook group (Solar Cleaners Network), there's been some talk about how we should approach new clients. The consensus seems to be that we should avoid emphasizing that cleaning the panels will directly increase productivity or lead to a certain percentage of improvement. Instead, we should focus more on the maintenance aspect—preventing hot spots, addressing issues with the structure, etc. What’s your opinion on this? How do you present your services to a new client? Also, how do you ensure that clients will return after six months (if we’re talking about residential clients) after a one-time cleaning? Or what about commercial clients, where you have to return after three months, for instance?"

Hello everyone! My name is Teodor Marinchev, I am 22 years old, and I am from Bulgaria. I am starting a business in solar panel cleaning, and I would love to learn new things.
