Yes. That's what I do. No problems whatsoever.

When EDF installed my smart meter they told me to inform my FIT provider (E.ON Next) in case they wanted to move me to metered export.

It has nothing to do with either EDF or E.ON. It depends entirely what is says in you FIT contract. That is your agreement, and if they want to vary it then they need to get your approval.

With respect, I think you misunderstand.

Per the current Standard Conditions, deemed export is permitted where "it is not possible or practical to measure the
Export by way of Export Meter Readings" (see page 309 of the document). It's not possible to vary the Standard conditions by way of a FIT contract between my supplier and me.

If you have a specific reason to belive otherwise I would appreciate a link to the statutory text, court proceedings etc. that detail it.

No I don't misunderstand. I'm simply saying that the contract terms are paramount. I can know what my contract says, but I can't know what other contracts say, in different domains or different times. A simple but important point, to go back to your own contract and check what it says.

And I disagree. Law is paramount, contract terms can only work within the law. If the regulations made under the Electricity Act say something, you can't have a valid contract that says something different. (If you do have such a contract, that term is invalid.)

FWIW (which is not much, in this case) my FIT terms with E.ON Next state:

If Your System has an installed capacity of 30kW or less and You don’t have an Export Meter, then You agree to allow Us to deem the amount of electricity that Your System has exported to the local electricity network using Ofgem’s guidelines.

Hi all, had solar since 2015, have a 3.5kw system and it's about paid for itself, so looking at next steps, which is about using some of the power I am exporting.

Given that I am a pretty high energy user, with 2 teenagers in the house, and so far my solar production is very good for about 8 month of the year I want to try and reduce my grid consumption to as near to zero as possible between April and October down from the circa £900 it is costing me per ear for electric at the moment (yes I change my tariffs regularly to try and get the best deal).

Any advice greatly appreciated.

How much are you importing from the grid during those 8 months? Do you have monthly meter readings that will let you work this out?

I've just posted my monthly stats over in the "talking bout my generation" thread. I don't have a battery. During Apr/May/Jun/Jul we imported 154/100/93/99kWh, roughly £23/15/14/15 worth of electricity (total £67). There isn't a lot of scope for a battery to save me money during the productive solar months.

Your numbers could of course be quite different to mine!

Don't know as I have no current way of monitoring, all I can tell you is the kids are both on xboxes all evening and the TV is on plus electric cooker.  The placement of my solar panels means that production slips off after about 6 this time of year.  My panels are split into two strings, I have a Sunny Boy 3600TL inverter so got 5 panels more of less SSE, and then 9 panels more of less east on another roof, so thinking about moving them around and keeping the east facing but when I have a SSE facing extension with a flat roof putting the other string on there and adding another couple of panels to take it up to 4kw.

Sorry another question, do I need to tell anyone about that in terms of FIT providers or can I just do it?  Or maybe add another 3 or 5?

If you have a Zappi and hub then the Myenergi app will show you your data for generation, consumption, import and export.

Yes thanks, will now but I've only had it 2 weeks.

People with EVs who started on the Vehicle-to-Grid trials were asked as a condition of the trial to agree to a change in their contract.

Exactly what I was thinking.  You need to agree to a change of contract to cancel your FIT.

"Edit, yeah if you add panels on same inverter you need to tell fit... however be aware they will either reduce your fit by a percentage or cancel it altogether... thats what edf told me when I asked.

Hence I went with a stand alone system instead.

If it doesn't go through you fit meter, the fit provider doesn't care.
The dno might, but thats a different matter really"

Yep to this too.  You'll probably need to get agreement from the DNO which will cost.    

I installed my extra panels with micro inverters as the cheapest way to add some extra capacity.  

(Apologies to Solarchaser. For some unknown reason I was unable to use the 'quote' function).

Well, it depends on what the contract says, of course. In reality, I've never heard of anyone coming off deemed export due to having a Smart Meter fitted.

We had a smart meter fitted last year when we switched to Octopus and we're still on deemed export. FIT paid by EON.

Go on then, @Exiled_Tyke @orrery @EVandPV all three of you. What exactly do your contracts say regarding deemed export and export meters? We're all itching to know.

I posted mine above, in case you want to compare.
