    Hi everyone, I went out canvassing today to get more solar customers, and there were a few of the people who showed me their solar panel readings since 2010-2011 and the output power hasn't dropped what so ever even though they have never had their panels cleaned. So they turned me away and said they don't think there is need for cleaning as they have been producing the same amount of energy since they were new.

    Not to sure on what to say when they tell me this?
  2. Some panels really see little benefit in cleaning. Target the dirty ones!

    I have customers who's installers have told them they will never need cleaning
    I have other customers who have been told to have them cleaned three times a year. Who's right I don't know but my experience is that people believe what the installation company tell them.
