1 December 2016
During the fifth year of generation the system has generated 3426kWh and outperformed the SAP calculation by 17.7%. This represents additional income of 423 over the predicted 1305.

In addition to the 1723 from the Feed in Tariff payments, there was also a saving of 310 on the cost of imported electricity*, to produce a total fifth year return of 2033, some 386 and 23.4% above the projected 1647.

Total return (including import savings) over the first five years of generation has been 10385, 2568 (32.9%) beyond expectations of 7817 and representing an annual total return on investment of 22.1%.

During August 2016, total income from the system reached an amount sufficent to cover the original cost plus the interest on that sum had it been invested.
* a small proportion of this saving will be due to changed occupancy patterns during the year.

5 October 2016
Payment of 652 for energy generated in the three months from July to September has been received after submitting September's reading on 29 September.

21 August 2016

During the third year of generation the system has generated 3408kWh and outperformed the SAP calculation by 17.2%. This represents additional income of 385 over the predicted 1304.

In addition to the 1688 from the Feed in Tariff payments, there was also a saving of 393 on the cost of imported electricity*, to produce a total third year return of 2081, some 519 and 33.2% above the projected 1562.

Total return over the first three years of generation has been 6078, 1513 (33.1%) beyond expectations and representing an annual return on investment of 21.9%.
* a small proportion of this saving will be due to changed occupancy patterns during the year.

3 October 2014
Payment of 654 for energy generated in the three months from July to September has been received after submitting September's reading on 29 September. Payment within five working days of submitting a claim would seem to be the norm.

2 July 2014
Payment of 626 for energy generated in the three months from April to June has been received after submitting June's reading on 29 June.

23 April 2014
EDF have written to advise that they may cancel Feed in Tariff payments as they have failed to gain access to the generation meter. They require to do this every two years to take a reading and to check the installation. Failure to respond to their letter within 10 days will, they advise, mean that they will suspend payments and contact OFGEM. With families quite commonly taking holidays away from home for periods of 14 days, 10 days is clearly an inadequate period within which to respond to such a threat.

To make matters worse, EDF have, in fact, made just one attempt to gain access to the meter despite their claim to have done so on three occasions and to have left written notice on the third of those occasions.

2 April 2014
Payment of 241 for energy generated in the period January to March has been received after submitting March's reading on 28 March.

1 April 2014
Feed-in and export tariffs of 46.81p per unit/kWh and 3.3p per unit/kWh have been updated in line with inflation using the annual RPI rate of 2.7% as at December 2013. The new tariffs are 48.07p and 3.39p respectively with the effect that each generated kWh is valued at 51.46p plus the savings on energy that does not need to be imported from the grid.

7 January 2014
Payment of 177 for energy generated in the three months from October to December has been received after submitting December's reading on 30 December.

3 December 2013
During the second year of generation the system has generated 3486kWh and outperformed the SAP calculation by 19.9%. This represents additional income of 379 over the calculated 1304.

In addition to the 1682 from the Feed in Tariff payments, there was also a saving of 389 on the cost of imported electricity*, to produce a total second year return of 2071, some 550 and 36.2% above the expected 1521.

Total return over the first two years of generation is 3991, 988 and 32.9% beyond expectations.
* a small proportion of this saving will be due to changed occupancy patterns during the year.

3 October 2013
Payment of 626 for energy generated in the period July to September has been received after submitting March's reading on 30 September. It would appear that EDF's original committment to make FiT payments within 60 days is no longer relevant and that they are turning round claims as they are submitted.

1 August 2013
July 2013, with a total output of 569.240 kWh, 40.8% above the SAP prediction and valued at 276, has been the highest generating month to date.

3 July 2013
Payment of 714 for energy generated in the period March to June has been received after submitting June's reading on 28 June.

As was the case in June 2012, EDF's estimate for generation between the submission of March's reading and 1 April when the tariff was increased was an overestimate which has led to a small underpayment.

1 June 2013
EDF have requested a generation meter reading prior to the end of June. Once again they have asked for the meter to be read 'in the next few days' as they may need to validate the reading.

4 April 2013
Payment of 159 for energy generated in the period January to March has been received after submitting March's reading on 27 March.

1 April 2013
Feed-in and export tariffs of 45.4p per unit/kWh and 3.2p per unit/kWh have been updated in line with inflation using the annual RPI rate of 3.1% as at December 2012. The new tariffs are 46.81p and 3.3p respectively with the effect that each generated kWh is valued at 48.46p plus the savings on energy that does not need to be imported from the grid.

1 March 2013
EDF have emailed their usual request for a generation meter reading to be provided by the end of the month. There is, however, a new element to the request on this occassion as they ask for the meter to be read 'in the next few days as we may need to validate your reading'. This is followed by a warning that if they 'have not received or are unable to validate your reading, payment could be delayed to the next quarter'.

7 January 2013
Payment for energy generated in the period October to December has been received after submitting December's reading on 30 December.

2 December 2012
After the first full 12 months of generation, the system has generated 3293kWh and outperformed the SAP calculation by 13.1%. This represents additional income of 229 over the calculated 1305.

In addition to the 1535 from the Feed in Tariff payments, there was also a saving of 389 on the cost of imported electricity*, to produce a total first year return of 1924, some 442 and 29.9% above the expected 1482.
* a small proportion of this saving will be due to changed occupancy patterns during the year.

3 October 2012
Just five days after the latest generation meter reading was submitted to EDF, payment of 545 has been received. Total income from the panels since 2 December 2011 amounts to 1387, with savings on imported electricity to be added.

1 October 2012
EDF have sent notification that payment for the period from 29 June 2012 to 28 September 2012, the most recent date on which the generation meter was read, will be made within five days.

4 September 2012
The SAP prediction of income of 1262 from generation for the entire year has been met after only 277 days.

1 September 2012
EDF have requested a generation meter reading prior to the end of the month.

17 July 2012
EDF have sent notification that payment of 635 for the period 21 March 2012 to 29 June 2012 has been made by BACS transfer. This is in respect of the 1359kWh generated during that period. As the Feed in Tariff rates changed on 1 April 2012 in line with inflation, EDF have estimated the generation meter reading for 30 March. Their estimate is a little inaccurate and has resulted in a small underpayment. At 19 days after submission of the reading, the payment was made well within EDF's 60 day target.

15 June 2012
EDF have requested a generation meter reading prior to the end of June.

24 April 2012
EDF have sent notification that payment of 206 for the period 22 November 2011 to 21 March 2012 has been made by BACS transfer. This is in respect of the 460kWh generated during that period at the rate of 43.3p for each kWh generated, and 3.1p per kWh for the 50% of the generated power which was deemed to have been exported. At 34 days after submission of the reading, the payment was made well within EDF's 60 day target.

1 April 2012
Feed-in and export tariffs of 43.3p per unit/kWh and 3.1p per unit/kWh have been updated in line with inflation using the annual RPI rate of 4.8% as at December 2011. The new tariffs are 45.4p and 3.2p respectively with the effect that each generated kWh is valued at 47p plus the savings on energy that does not need to be imported from the grid.

21 March 2012
After a wait of four months, EDF have emailed confirmation that the installation has been registered with OFGEM. The email also included two documents: 'FIT Terms _NHH_ - V1.7 TERMS ONLY' and 'Statement of Terms'. The former is to be signed and returned to EDF by Recorded Delivery post within 14 days and confirms details of the installation and its registration with them. The latter is for reference only. Unfortunately, a promised meter reading form was not included and so had to be requested separately before being completed and returned with the 'Statement of Terms'.

25 January 2012
EDF have confirmed that they will miss the March deadline for receipt of their Statement of Terms/Contract and that that will result in a generation meter reading being requested in June. With payments being made within 60 days of a reading being submitted (EDF say they are currently making payments within 40 days), this raises the prospect of the first payment being made some 8½ months after the FiT application form was received by EDF. EDF confirmed that today's lost appeal by the government can only make matters worse.

18 January 2012
After a long period without any contact, a telephone call to EDF elicited the news that they were 'hoping' to be able to supply a contract 'by March' when the next meter reading would be due. If they were unable to meet that deadline they expected to despatch contracts 'soon after' and the meter reading would then be required at the end of the next quarter in June. If that was to be the case, six months would have elapsed since the system was commissioned and payment could be delayed by another 60 days.

A welcome gift of a 'Sunny Beam' for Christmas to make following output much easier!

3 December 2011
EDF wrote to confirm that they could confirm that 'you have provided the basic required information to form eligibility at this stage for the higher rate tariff (e.g. 43.3p per unit/kWh) and you do not need to do anything else at this time'. They also advised that the next step would be to make final checks on the application and then register the system with the scheme administrator (Ofgem)

25 November 2011
A telephone call to EDF confirmed that they had received the FiT application form and that on first inspection it appeared to be valid.

24 November 2011
The Feed in Tariff application form, along with supporting documents, was emailed to EDF.

22 November 2011
The system was installed and commissioned.
