With the government originally due to review the Feed-in Tariff in summer 2012 it was a surprise to everyone when they announced a consultation for 31st October 2011. However this was not nearly as big as the surprise as the outcome of the meeting!
The government have decided that from the 12th December 2011 the Feed-in Tariff will be reduced by around 50%. See latest Feed-in Tariff »
Another meeting, the fourth in 9 months, has been planned for the new year which will consist of a comprehensive review.
The number of Solar Panels you have on your roof is determined by several key factors. Each of these factors plays a role in helping you decide on the number of Solar Panels you should fit on your roof.
Size of your roof
The most obvious factor determining how many Solar Panels you should fit on your roof is the size of your roof. If you can only fit eight panels on your roof then you are limited to eight panels.
When estimating the number of panels you can fit on your roof you should consider laying the panels both Portrait and Landscape.
The number of solar panels you have fitted obviously has a direct impact on the initial cost of having the system installed. However it is worth remembering that you are unlikely to have more panels added to your system once it has been fitted.
The solar panels themselves are relatively inexpensive with a large part of the installation cost going on tradesman and scaffolding.
The government has introduced the Feed-in Tariff to incentivise people to produce their own electricity. However the tariff has different tiers depending on the size of your renewable energy system.
The highest tier of the Feed-in Tariff is available up to 4 kW systems therefore its less cost effective to exceed this system size unless you are looking to get a system size of between 8 – 10 kW.
Overall it is advisable to get as many Solar Panels as you can on your roof without exceeding the 4 kW system size as you are unlikely to add more panels once it has been installed. Soon we will be adding a roof size calculator to our website so check back soon to calculate the size of your roof.
With almost all of the renewable energy sources tariffs last for 20 years, with the exception of Solar PV which is 25 years.
Is the tariff fixed and guaranteed for the entirety of the period?
Yes – once the start any given tariff, it is guaranteed for the full period shown above and is index linked.
What does index linked mean?
Each year a set level of generation and export tariffs will be adjusted pro-rate to the retail price index. The tariffs administrators will publish the updated tariff levels prior to the budget on the 1st of April each year.
Do the tariffs ever change?
Agreed systems tariffs will only change with the index-linking above.
Looking forward systems not yet registered tariff levels might change at the first review.
How long does the scheme last?
The incentive scheme is open to new installations until the end of March 2021 and so long as the UK is on target for its target mark of 15% renewable energy creation by 2020 this is likely to stand.
In theory a PV installation registered sometime in early 2021 will still be valid and receive tariffs until the 31st of March 2046.
