    On residential???

    I have been looking at some panels over the weekend, and they look clean!

    Some have been installed 9 months, others just over a year.

    Are they really going to see an improvement, AND be more efficient?

    How will they know?

    Do they have a % meter or something?

    Input.....input i need inputtttttttttttttt.

    Yeah they`ll be able to know how much electricity is produced. when there installed "free", companys take what isnt used after a certain time of day and sell it to power grid.. so they must know.

    bit of a vague answer but some one else will go in to more detail i`m sure (yawn)

    I think unless you have thousands of these on a farm the output increase after cleaning would be minimal.

    So just say you charge a customer £30 a year to clean the panels on roof.

    Are they going to get this back within the year?

    most arnt paying any thing. free supply during the day and stored energy is what the installation company make their money on.

    they`d only produce more power in the day so save on using any excess grid power to back up what the panels make.

    most will have them cleaned from a aesthetic point of view rather than a saving.

    One customer I did has a monitor for each panel on his system and he could see the power produced on each panel I was cleaning increase, phone him the next day to see how it was and he said even though it was cloudy there was more power been produced on the cloudy day than it did the day before on a brighter day.

    Some people say that there is a 25%+ more power being produced when cleaning is done.
    Some installation companies say in there warranty that they have to be cleaned to keep warranty valid.


    This panel was cleaned after a year of it being up, (in bedford)
