    There was a letter in the paper today - some bloke saying it was 'technically impossible for home generated electricity [solar, mini-windmills etc.] to be fed back into the national grid.'

    If you think that's a load of ****** you should read the Daily Mail letters page.

    I have a customer with a roof full of solar panels and a 2 way meter so he can sell his excess generation to the grid. He gets more for his excess units than he pays for standard units from the grid!!

    Yes people have 2-way meters and get paid for the excess they generate (in theory), but does it really go back into the 'national grid'? Because my windmill generates 250W on average for 24hrs, say, does that really mean a power station somewhere can run for a fraction of a second less (presumably) as a result?

    In reality the excess is probably just being used by appliances in nearby houses on the same phase and reducing the load on the local transformer. But this is nevertheless part of the grid.

    Question 1

    The customer with a roof full of solar panels and a 2 way meter - how much would that cost to install said solar panels?

    Question 2
    How would the windmill push back the voltage from the national grid, how would this actually work? Does the voltage have to be chopped to maintain the frequency of the mains or to match the frequency of the mains?

    thanks gents
