    Actually no, most energy companies are taking the view at the moment that Export Meters are too costly to be worth fitting, and are therefore offering "deemed export" - basically they just assume that you will use half of what is generated and export half, so they will pay you 41.3p per unit on everything you generate plus 3p per unit on half of that amount.

    That said, they will still be rather unhappy if they find at the end of a billing period that your meter reading is lower than it started.

    .......and when they 'phone up to complain, just put them on hold and ask them to press half a dozen telephone keys at random and play them a bit of music.:rotfl:

    Eventually tell them that it is a 25 year contract and if they can get the cheque to you by the end of the week you will agree to take your business elsewhere?:T

    BTW EDF is trying to get involved in the installation of PV panels: 0800 0511905 (I have no idea if they are any good or competitive on price.)

    Anyone on here had the system from A Shade Greener installed (or pending or surveyed) in Derby ?
    I know DERBYshire is available as an area within range but I think Derby itself might be borderline.

    Where is a representive from the company when you want / need one, especially when there was one answering queries like this. Can we have Sarah back PLEASE ?

    Do you think they use Google Maps to work out the "1 hour range" ?

    If I use the directions facility and put my postcode in as one location and TANKERSLEY as the other (it's 0.8 of a mile from junction 36 of the M1) it comes up with 2 possibilities.

    M1 down to junction 25 and then into Derby via the A52 or only down as far as junction 28 and use the A38 instead.

    It calculates the distance via the A38 as 51.3 miles and a "travel time" of exactly "1 hour 0 mins"

    It is actually further using the A52 at 54.6 miles but has a reduced time at just 58 minutes.

    Hope this means I am within range because my roof is pointing just where it needs to and I'm sure it is plenty big enough.

    So any Derby success ?

    It's very simple solarquestions - just read it all on the ASG site ;)

    Won't export meters be redundant when we all have to have smart meters? And therefore won't people gain less free electricity from ASG systems?

    Sorry, new to the forums.

    Not sure if someone has mentioned this already. Sorry if they have.

    So it's estimated that the govt. will give £800 per year (est. on a 3kw system).

    so.. here's my math:

    £0.413p / kwh (less than 4kw retro fit).
    ISIS installs 3kw system.

    £0.413p x 3 = £1.239 (earning per hour from Govt. FIT scheme).
    Shortest day of the year has 7hours a day. (worse case for whole year avg.)

    £1.239 x 7 = £8.673 / day

    £8.673 x 365days = householder gets paid £3,165.645 / year.

    This is not including the 3p "deemed usage" either.
    What have I calculated wrong? pls help.

    (of course, this money goes to ISIS if I take the free install option, and to me if I pay up front)

    Your calculations are flawed for 2 reasons.
    1) You are assuming that all daylight is strong sunlight (e.g. your worst case scenario of 7 hours a day)
    2) you are assuming that the numbers of hours of sunlight per day is linear

    A better way of looking at the calculations would be the following:

    A PV system will generate a number of units directly proportional to how far North or South you are in the county. Southern counties will have a higher percentage, Scottish will be lower. I live near Chester, and over the last two years, I have got roughly 850 watts per Kwp installed

    So, my system is 1.44 kwp, and 1.44*850 equals about 1200 units per year.

    1200 * 41.3p, would be £495, plus your export bonus of maybe £20 (1200 * half exported* 3p)

    So if you are further south than Chester, maybe do 900 units per kwp, and if you are further North, maybe do 800 units per kwp

    Hope this helps

    PS you have a final flaw, the government doesn't give you a penny. They tell the energy companies that they must do this, so the money comes from them, not government.
