Free installs - advice

My monthly bill wasnt even £100 a month before the install and that's with a 6 bed detached and 6 people living in the house so I doubt you will save that much Jazz. £150-£200 is what I make from the feed in tariff which isn't bad for an £8000 outlay. The actual saving on my bill is about 30% and prior to fitting my monthly direct debit had gone up to £83 a month. The big money is in the feed in tariff that the government pay.

I meant £200/year.
So you make £200/month on feed-in, what tariff is that on?

I am on the old 46p a unit one I just got in time. I think I got just short of £1900 last year at 43p a unit plus about £300 of savings for the year.

Tell me about it...    

I work from home so make sure any high energy use goes on when the power is pouring in, so we use just about every drop generated.  I can see that if the house is empty during the day, you're not going to save enough for it to be worth the hassle unless you're getting a good feed in tariff.

There are people home all day at ours and as you say washing machine/dishwaser etc is all done during daylight hours to maximise.

I'm getting a couple of people round next week as the green deal allows you to pay for the install using the savings.
I am also using the immersun immersion to heat up the hot water with the electric that isn't being used.

So how much do you produce on a cloudy day? Is it enough to run dishwasher etc?

I use 6200 kW/year on electric and 13500 kW of gas in a 4 bed detached.
In Nov 09 I was paying 8.3p/kWh and now paying 12.8kw/h for electric and 2.7p/kWh for gas which is now 4.28p/kWh

54% increase on electric and gas in 4 years.

On a cloudy day in the summer it can be 10-11 units in the winter it can be less than 2. I will check how much I pay when I get home.
