Some one I know has been offered a solar panel deal

The information I have been given is that the panel installation would
normally cost 10k

At that rate it would pay for itself in ten years due to a combination of
electricity not paid for and inconme from the excess going into the grid
they say

They are offering the panels for 250ukp and say that they make their money
by taking the money from the excess going into the grid

My current electric bill is about 80ukp per month

How big would the panels need to be to generate in excess of this usage?

I cannot see how this could ever work so can some one please explain

Regards

It's been done to death on here in the past. To work out how much you
could generate, assume an average output over a year of about 2 Watts
per square metre of panel. Peak is higher, and comes in the Summer, when
your energy use is at its lowest, but that's a reasonable average over
24 hours a day, 365 days a year.

Points at a brochure which explains it, but the profitability comes from
the enhanced rate they pay you for the power you feed into the grid.

Someone is confused..
there are companies that will install the panels free.
they get FITs payment, you get the free electricity
they are effectively renting the roof space.

After 25 years when the FITs stop the panels are yours.

Don't solar panels generate DC?

How is this fed back into the N grid?

Yes.

How is this fed back into the N grid?

Using a grid tie inverter that converts DC-AC and synchronises the
frequency and phase of the AC to the grid supply.

There is a grid tie inverter, Does lots of amazing things.

They feed a ~£1k DC-AC converter that synchronises to the grid.

It also cuts the feed if there is a power cut, they don't want their works
getting a shock if they are fixing cables and have turned the feed off, i.e.
you can't use the panels to provide power in a power cut with the standard
installation.

Doesn't this make it one of those "Solar Farms" that have specifically
been sidelined by this year's budget? Only individuals are supposed to
get the full FIT from now - yes?

No.

Only installations on domestic (and possibly very small business) property
gets the money.

It's irrelevent who owns the installation.

They are having a review of very large (50Kw+) arrays. Dunno the
outcome.
It was to stop foriegn firms coming in and making off with all the
money as has happened with wind turbines out at sea.

You can't do this.
The reason being only accredited installers are allowed to do the
work.
You need a certificate to connect to the local grid and another one to
send to whoever you are selling your power to. Plus a copy of the
invoice.
Only accredited installers can give you these.

In practice tthe best size to go for is 4kw if you have room. This
gets the optimum price for your power. The next price band is 10Kw
but few people have a roof that big. (Barn roof size).

I have a 4Kw array, we do all our power using activities in the middle
of the day.
In Summer we can cut our electric by 80% but we are retired and able
to do this.
We have generated 630Kwh in 35 days. Best day 29 Kwh, worst day 6Kwh.
It will be a lot less in Winter.
I need to average 10Kwh/day over a year to get the projected money
back.

Not actually very informative since a full year's data is needed. I
have been recording my daily power generation.
I need to avarage 10kwh/day over a year to make the projected money
back.
So far I have averaged 19 but Winter is yet to come.
Max has been 29, min has been 6.

Have you recieved payments from your buy & how long do they take after
getting the meter reading.?

They also didn't reveal how much the system cost, so whole statistic
becomes a bit meaningless.
