Solar Panels Query

[Highlander]

The guy says the idea is to run as much electricity as possible during the day when its free
but how do you know that you are using too much and therefore paying for the extra?

You cant really answer this River, if you have a 3kw system, which it probably will be, [ we need to know how many panels when you know], then if the sun is blazing, you could be producing 3kw at any one time,.. then you would be hard put to use more than you are producing

As the days get less sunny, you will get less energy free,..etc, etc

But remember that you still pay your electric bill as normal,.. so if your bill was normally £600 a year and we have a good summer, your bill will be considerably less ,.. you will still have a bill though, because you will bound to use more in the winter than you produce

Last year we produced more electric than we used, and made over £400,.. but of course we also get paid the tarriff at 43p per unit,.. that money will go to your landlord,..[ well its not that much now, its something like 20p per unit ]
