Just bought a housr with Solar Panels on FiT contract ... help

Hi all,

Completed on our new home about a month ago and it has solar panels, I've finally got all the documentation to Eon (who they were with) and got the tariff sent through, but I'm a little confused of exactly what we'll get paid.

Below is what they've sent through for my approval. 

In terms of our set up, we have a Fronius IG TL ... no idea if this passes 100% back to the grid or some to the house (assume it doesn't store any as I think you need batteries for this)

So based on the above and below, what would we get paid per unit the solar panel makes?

Thanks in advance for any help

It is pretty clear. You will be paid 27.85p for every kWh that your array generates. You are on a deemed export tariff which has a 4.25p/kWh rate. Your export payment will be based on 50% of your total generation x 4.25p.

Both the FIT and exports are adjusted annually for RPI.

If it's sunny and you turn the oven on, the power from your solar PV will be used towards powering it, any excess will then be sent out of the grid, similarly, if there isn't enough solar PV and you turn the oven on, the difference will be made up from grid draw.

Electricity, however its generated, just goes to the nearest point its needed basically.

You'll get to use the electricity generated as long as you are consuming it at the same time (unless there is a battery it cannot be stored). This should lower your consumption from the grid and hence your bills.

You'll also get paid for what you generate - whether you use it or not

I have an iboost which send electricity to my immersion heater to heat water. If you've got one of those you'll have 2 small white boxes with "iboost" on them. One probably next to the RCD with a flashing light and another close the the water tank (in the airing cupboard?). You can press some buttons on it to see the saving in kwh.

You will get the 27p for all power generated whether you use it or export it, Around 4000 kwh a year. You will get the 4p for 50% around 2000 kwh a year.

The Solar is a higher voltage +2v above the grid, So will be used in the house first before going out to the grid.

Make the best effort to use washer/dryer between 10am-4pm, Anything below 4kw will not import from the grid if its sunny.

 Other brands of Solar Power Diverters are available, Immersun is another.

Thanks so much for all your quick replies! Super useful! Sounds like we need to ensure we use energy intense stuff during the day as much as possible Will check to see if its linked to the immersion heater but doubting it will be as it seems quite an old heating system the house has!

Some people simply manually turn on the immersion when its sunny, They are 3kwh usually so it likely imports 20%-50% when clouds passes by, If the is a timer 30min at 1pm would have a good chance topping it up without importing too much.

Diverters monitor the export so only a very little is imported.

It is 12 years and two months since the solar panels were installed and in that time they have generated 31274.87 kWh of electricity.  That's 3076 kWh per year on average.  That's  £856.73 per year for your generation plus £65.37 per year for your deemed export, if you achieve the average amount of solar generation.

Plus all the free electricity you use while it's being generated.

Thank you, didn't realise you could work that out from that but looking now it's quite easy to do! Very interesting and a great addition to know, will certainly help with the bills since the price increases
