    Quite a day, not only broke the 10MWh mark, but also got an Hawaii, 5.57 to be precise(ish). Plus best day of the year, and best week too.

    Currently forecasting 113% for May if the rest is average ...... weatherman is not too confident of that.

    Best day yet for me!
    23.04kWh = 5.76 ho's - same as you tunnel ;)

    I've now exceeded April's figures, up a ladder tomorrow too to clean the bird pooh off so may be gone for some time!!!!

    As an aside, thoughts/suggestions on panel cleaning? My jetwash won't reach,not got the power but then it is 13 years old!, so looking for extending poles with brush attachments?

    That's a cracking result so far! Better than initial expectations I guess?

    Today was my best day @ 21.16kWh / 5.3 O's - still room for improvement too, from looking at the generation curve.
    I've also just exceeded April's monthly total.

    Rely on the elements to do it for you?

    I can't imagine the economics make sense in terms of your valuable time spent cleaning.

    It's going to hoof it down with rain overnight/morning according to the forecast so would expect that to give the panels a decent wash.

    Yes, My Installer gave me a spread sheet with all the info i.e. output, future fuel costs, RPI, etc and estimated by year 7, I would be in profit.

    Some of his numbers were higher that actual, but the estimated kWh were around 10% down on what I'm achieving:T

    Some people may say the fuel savings are not all down to S/P but, having them fitted (and using Wattson) has made me more aware of where my cash is going;)

    Considering I was paying £120.00 a month for electric and gas 5 years ago, and I am now paying £70.00 a month (OK some due to being more aware) I believe I will be in profit in year 5:D

    Hi

    That's a really decent saving considering the increase in fuel prices over the last 5 years ....

    Considering that the combined gas & electricity increase over that period must be at least 50%, you must now only be consuming 39% -(70/(120x1.5))of the energy you were using 5 years ago and the annual current cost savings would be £1320 (((120x1.5)-70)x12), which is pretty much the same as the average UK household total dual fuel energy expenditure (including standing charges), or the cost of ~9000kWh of imported electricity.

    Well done, but I reckon that the majority, as opposed to "some", of the saving isn't pv related ..
