    can anyone help, did my first solar clean this week and apart from a school boy error of taking wrong pole was nice job and custy could see difference straight away, then they asked what savings would they get. As didn't have any data prior would you;

    • Take initial data readings between two times prior
    • Find out there rate of return (is that pence per kW?)
    • Clean
    • Take two further readings on a similar type day
    • Work out difference and should be "hey presto!" wonga saved!!
    Or is this completely wrong.

    Just about to price a commercial and want to sound like I know why I'm on about

    It would be almost impossible to calculate the savings as you could never replicate the same conditions.

    With that on mind, just say 10percent.:thumbsup::D

    Why test between two times?
    Just get a reading off the inverter/charge controller at the same time on two cloudless days.

    First figure that comes in to you head below 25%. If they are more persistent tell them to look on the internet. Most of the time they probably won't bother.
