New UK Feed-in Tariff – 21p

After a period of uncertainty we now know where we are with Feed-in Tariffs for rooftop solar in the UK. Now that PV costs have come down considerably (e.g a 4kW system can now be around £7,500 as opposed to £20,000 back when the FiT was launched in April 2010) the FiT has come down too. It is now 21p/kWh for those that can demonstrate that they have an EPC (Energy Performance Certificate) of ‘D’ or better. Oherwise the FiT is 9p/kWh. This is to encourage people to invest in energy efficiency first.
The FiT is set to come down again in the coming months. We will be updating our software soon to reflect these changes. Our priority for the moment has been our work with the Energy Saving Trust so you can check out the Solar Energy Calculator on their site which is now updated.

Solar Feed-in Tariff reductions announced by DECC

Feed-in Tariff Key Figures:

On Monday the 31th October 2012, the Department of Climate and Change (DECC) announced the results of the UK Feed-in Tariff review.

Here are the key figures:

  • Feed-in Tariff (generation tariff) will be 21 p/kWh for installations after the 12th December 2011
  • 

  • The export tariff remains the same at 3.1 p/kWh as does the tariff lifetime of 25 years.

So those who have their installations complete before the 12th December will receive 43.3p/kWh over 25 years (increasing by Retail Price Index (RPI) every April). Those that have their installation completed after 12th December they will receive 43.3p/kWh until April 2012 and then 21.0p/kW for the remainder of the 25 year term.

Feed-in Tariffs have proved a success

The reductions in the solar PV Feed-in Tariff represent a 50% drop in support which may alarm some individuals and organization. Howver, Solarjuice support this decision as PV install costs have fallen considerably since the introduction of the UKs Feed-in Tariffs, back inApril 2010, and these tariff reductions are simply in-line with installation cost reductions. At the start of the Feed-in Tariff a 4.0 kW(p) solar PV roof top  installation would have set you back ~£20k and now costs are much closer £10k – which is a similar 50% drop.

The UK now has over 40,000 solar PV rooftop installs and an established network of 3000 MCS accredited PV installers to continue the good work.  Now that the ball is rolling we expect the price of a 4kW(p) installation to continue to fall.  This is a testament to the efficacy of Feed in Tariff schemes which are introduced as a temporary measure to stimulate the grow certain areas of key concern such as clean, secure, renewable energy.

Energy Saving Trust and Solarjuice release the Solar Energy Calculator

To coincide with the launch of the national Energy Saving Week on the 24th October 2011, the Energy Saving Trust and Solarjuice are launching the Solar Energy Calculator.

This calculator is based on the Solarjuice Juice-o-meter software engine with information and figures on such aspects as electricity costs from the Energy Saving Trust. The calculator can be found here: http://www.energysavingtrust.org.uk/Generate-your-own-energy/Solar-PV-electricity-panels/Solar-Energy-Calculator

Energy Saving Trust LogoIan Cuthbert CPhys, Microgeneration Advice Manager, at the Energy Saving Trust says: “The Energy Saving Trust is happy to be working in partnership with Solar Juice to develop our joint Solar Energy Calculator.  Installing solar photovoltaics is a big decision for UK householders to make. It is therefore important that householders are given the best possible estimates for their annual generation, savings and income from Feed-in-Tariffs in order to make an informed choice about whether or not to go ahead.  Overall, we hope that this new calculator will give people the confidence they need to go ahead with their installation.”

Unlike most other calculators, our financial figures are based on today’s money (i.e. ‘real’ accounting terms). This means that we do not have to make an assumption about inflation over the next 25 years (a difficult thing to do!). It also assumes that energy prices rises over 25 year will be in-line with inflation.  Although current energy prices rises are ahead of inflation we hope that over 25 year the UK will have sorted out its energy needs out.   

However, we do appreciate that it is useful to see income from a ‘nominal’ accounting perspective (i.e. including inflation) so the EST/Solarjuice team are working with the Department of Climate and Change (DECC) on predictions for inflation over the coming 25 years for both Retail Price Index (RPI), to which the Feed-in Tariff is linked, and electricity price rises.

The Green Deal: New Financing for Energy Efficiency and Generation

The Green Deal is billed by the government as a ‘revolutionary programme to bring our buildings up to date’ and is due to come in force in October 2012. It offers UK residents (specifically ‘bill payers’) a chance to have 100% of the upfront costs related to certain energy saving and energy generating equipment funded by businesses. This is in effect a loan which is paid off over the lifetime of the installation by the money derived from savings on monthly bills. The golden rule of the Green Deal is: ‘estimated savings on bills will always equal or exceed the cost of work.’

The Green Deal sounds great and, in theory, Solar PV technology is potentially covered! Solarjuice take a closer look…

The Green Deal is a response by the government to its legally binding national carbon emission targets and is part of the new Energy Bill 2010-11. The British Government first committed to cutting UK carbon emissions by 60% by 2050, compared to 1990 levels, but in October of 2008 increased its commitment to an 80% reduction by 2050. UK homes contribute 27% of the UK’s total carbon emissions and it is estimated that 85% of our existing housing stock will still be around in 2050. Therefore, if the UK is to achieve its target, it is imperative that homeowners improve their energy performance.

The Green Deal is the coalition government’s main incentive to convince bill payers to ‘do their bit’ and is a key component of the Energy Bill 2010-11. The Bill has three principal objectives: tackling barriers to investment in energy efficiency; enhancing energy security; and enabling investment in low carbon energy supplies.

The Green Deal loans help pay for energy saving/generating technologies but the government is keen to stress that it is not a loan in the typical sense as consumers are asked to see it as a form of financial incentive, a way of removing the need for large upfront capital outlay, effectively a ‘pay-as-you-save’ scheme. The golden rule means that you will never pay back more money that you are saving on your monthly energy bill. Let’s illustrate this with a Solar PV example:

If we assume that your monthly electricity bill is £50 a month and you save 30% after installing solar PV you will save £15/month. Therefore under the Green Deal the ‘loan’ for your PV system should not cost you more than £15 a month in repayment (if you haven’t already done so, try our Juice-o-meter to check how much you could actually save on your bill). Solar PV panels are usually guaranteed for 25 years but can operate for over 40 years. If the green deal states that the maximum loan period is 25 years you would only be able to pay back £6,500 in this period (assuming a modest 3% annual energy inflation rate). Although PV installation costs are steadily decreasing, this amount is unlikely to cover PV system costs for sometime. However if the Green deal was to allow you to take the loan for 40 years you would be able to pay back £13,500 (@3% inflation) and be able to repay the initial costs. If you are allowed to take a higher inflation rate – e.g. 8% – you would be able to payback over £13,000 in 25 years! 

So in theory funding is possible for Solar PV but it depends on the cap on any finance deal imposed by the government. For example a householder may be limited to a loan of £6,000 in which case installers may be able to offer complimentary financing. The finer points of the Green Deal for solar PV will be announced by DECC (Department for Energy and Climate Change) in the run up to October 2012. Solarjuice will be looking for the conditions relating to the maximum loan amount, the maximum loan term for PV, the inflation rate and conditions surrounding compatibility with the existing Feed-in Tariff scheme for solar PV. So far the government have said “Other financial incentives such as Feed-In-Tariffs and the Renewable Heat Incentive will complement the Green Deal. Green Deal Providers may wish to promote all these options with customers. However, DECC does not intend to create a mechanism for combining these financing streams.”

Green Deal Finance is set to cover the following technologies:

Heating, ventilation and air conditioning Condensing boilers. Heating controls. Under-floor heating. Heat recovery systems. Mechanical ventilation (non-domestic). Flue gas recovery devices.
Building fabric Cavity wall insulation. Loft insulation. Flat roof insulation. Internal wall insulation. External wall insulation. Draught proofing. Floor insulation. Heating system insulation (cylinder, pipes). Energy efficient glazing and doors.
Lighting Lighting fittings. Lighting controls.
Water heating Innovative hot water systems. Water efficient taps and showers.
Microgeneration Ground and air source heat pumps. Solar thermal. Solar PV. Biomass boilers. Micro-CHP.

 In practice, an accredited ‘Green Deal Assessor’ will examine your property and will recommend the most suitable energy saving measures to reduce your energy bills (loft or cavity insulation, double glazing etc). Should you wish to implement any recommendations, the assessor will issue you with a quote for a Green Deal Plan.

There is one other aspect in which the Green Deal truly differs from a traditional loan: you are not ultimately responsible for the loan, your house is and when you sell your house the obligations (and benefits) will be passed on to the new owner.

Solarjuice welcome the Green Deal and look forward to further developments to the scheme.

Thin Film and AZUR 2P coatings – IKEA and The Body Shop go solar!

Ikea and The Body Shop are amongst the big brands leading the way for solar PV in the UK. But there are many ways to juice up your building and these are two examples of very different methods.

Ikea has decided to go down the thin-film road for installations on ten of its UK stores. The £4million investment comprises 39,000 panels supplied by GS-Solar UK, a subsidiary of GS-Solar (Fujian) Co., based in Quanzhou, China. These panels, due to be installed by March 2012 in order to qualify for the highest Feed in Tariff rate, will cover an area of 31,000m2 and provide, on average, 5% of each store’s electricity requirements. These installation will generate around 1,600,000 kWh per year, or enough electricity for just under 500 homes. The stores fitted so far include Milton Keynes, Edmonton, Warrington and Southampton. The reason given for choosing thin film is primarily financial as thin film can be cheaper per installed Watt than more traditional mono or poly-crystalline PV panel and can be more suitable for the UK climate as they perform well in cloudy condition. Thin-film also has the lowest embodied energy which is important from an environmental/CO2 emission point of view.  With these UK solar installations, Ikea are adding to their worldwide commitment to renewables with major projects already completed in the US (573kW in Sacramento, California) and in Germany (449,000kWh and 149,000kWh in Regensburg and Freiburgrespectively).

By contrast, the Body Shop chose to use over 3,800 AZUR 2P modules to create an 883kWp solar photovoltaic energy system from AZUR SOLAR at their head officesin Littlehampton, West Sussex, and in doing so built the UK’s largest commercial on-roof Solar PV solution to date. One of the main reasons to select these panels is the unique “2P” coating. Whilst they come at a premium, they are virtually free of degradation and can produce around 15% more lifetime power. Whereas most rival panels see a steady drop off in performance, AZUR 2P panels offer the impressive guaranteed of 98% efficiency after 20 years (compare to a typical 80% efficiency after 20 years for crystalline technologies). It’s encouraging to see The Body Shop International, well known for its rigorous ethical standards and code of conduct, taking the lead in sustainable development as well.

At Solarjuice we are often asked which technology is better. The answer will depend on the situation for example whether you want to maximise energy production, CO2 savings or financial returns. Other consideration include the available roof space as thin film panels require a large area due to their low W/m2 (around half of crystalline PV). Other factors include panel orientation, local shadowing, aesthetics and the overall budget. The Body Shop had a specific energy reduction target that would be difficult to achieve by using thin film alone as Bill Hughes, international environment, health & safety director for The Body Shop explains:

“The installation of our own environmentally friendly solar PV solution using AZUR SOLAR manufactured and installed modules is an important part of our plan to reduce our CO2 emissions from the site by 50%, by 2015.  We have a long history of working to protect our planet and this project is a significant investment in our programme of initiatives to improve the environment. This approach remains true to our original values; by producing our own clean energy we not only secure a sound economic and environmental future for the business but we also confirm our commitment to reducing our CO2 emissions.”

Ikea on the other hand, is dealing with multiple site in the UK alone and made a commercial judgment that favoured thin film for their particular case.

Solarjuice believes that regardless of the technology both Ikea and The Body Shop made the a great decision to invest in the Feed-In Tariffs now and benefit no doubt from the goodwill generated by the positive publicity surrounding their environmental strategy.

UK Solar PV Feed-in Tariff rises from to 43.3p/kWh

Ofgem have announced the new feed-in tariff levels for the year: 1st April 2011 – 1st April 2011.  For normal solar PV installation (domestic retrofitting below 4kW) the Feed-in Tariff has risen from 41.3p/kWh to 43.3p/kWh.

Tariffs are adjusted annually to reflect the changes in inflation. Ofgem use the Retail Price Index (RPI) which for 2010 was 4.8%.

We have updated our Juice-o-meter to reflect the official 4.8% price so you can see for yourself how profitable a solar PV can be for you and your home.

Solar Thermal and the World’s first Renewable Heat Incentive (RHI)

The Feed-in Tariff has been with us now in the UK since April 2010. It was set up to help boost the amount of green electricity production from renewable energy technologies like rooftop solar electric (PV). A Feed-in Tariff is now in place in the best part of 50 countries world-wide and is really helping this important new sector to take off. 

But it is not all about renewable electricity…what about renewable heat? And what about rooftop solar thermal (and other technologies like heat pumps and biomass burners)?   

Before the release of the Feed-in Tariff, almost all solar installations in the UK were solar thermal – helping homes across the UK meet their hot water needs. But now, most solar installers have seen a complete switch from new customer who now wanting solar electric (PV). 

But solar thermal could be making a come back as the 10th of March 2011 saw the announcement, by the government, that the UK is to have the world’s first renewable heat incentive (RHI) to incentivise the uptake of renewable heat energy. So what is it all about… 

“This incentive is the first of its kind in the world. It’ll help the UK shift away from fossil fuel, reducing carbon emissions and encouraging innovation, jobs and growth in new advanced technologies.” (Secretary of State for Energy, Chris Huhne) 

Sounds good…Solarjuice investigates what the launch of the new RHI means for solar thermal…. 

First off, it is important to note that the Feed-in Tariffs are paid for by the Utility companies under a legal obligation made by the government. In contrast, the RHI will be paid for directly by the Treasury and so it is not as generous.  Let’s take a look at the figures… 

Main Facts: 

  • A typical UK solar thermal installation will cost around £3500-4000 (4m2 of rooftop evacuated tubes).
  • This will produce about 50-60% of your hot water needs (shower, bath, washing up, washing machine use for a typical 3-Bed home).
  • With RHI support the payback time will be around 15-20years.

The Details: 

  • Payments will be based on the amount of heat you generate – i.e. for each unit (kWh) of renewable heat energy which is produced and will be measured by a heat-meter.
  • The tariffs will be paid for 20 years to eligible technologies that have installed since 15th July 2009.
  • The first full system of RHI payments will be available to households from October 2012 (to coincide with the launch of the PAYS “pay as you save” Green Deal).
  • In the interim, up to 25,000 household installations can get a “RHI Premium Payment” to encourage take-up.
  • The RHI tariff scheme will pay 8.5p per kWh(th) for solar thermal installations.
  • The RHI tariff will increase annually in line with inflation.

During the RHI consultation period, which has lasted over a year, the solar thermal support was expected to be around twice this amount. Nevertheless this is still a £860m government scheme and is expected to increase green capital investment by £4.5 billion up to 2020. It is hoped that the RHI will “revolutionise the way heat is generated and used in buildings” and “reduce emissions by 44 million tonnes of carbon to 2020, equivalent to the annual carbon emitted by 20 typical new gas power stations”. 

So what is a RHI “premium payment”? 

Up to 25,000 installations from July will be supported by a “RHI Premium Payment” to help people cover the purchase price of green heating systems. For Solar Thermal this is likely to be around £300/unit which is around 7-10% of the install price. 

Those taking up the Premium will then be eligible for a RHI tariff from October next year. Details of the “RHI Premium Payment” and how this will apply will be released in May this year. There will be clear eligibility criteria in order to qualify for a Premium payment which include having a well insulated home (based on its energy performance certificate) and agreeing to give feedback on how the equipment performs. 

The full table, for all the renewable heat technologies covered by the RHI are given below. Further detail of the scheme can be found at www.decc.gov.uk/rhi

Feed-in Tariff review by UK government

It has just been announced that the UK Feed-in Tariff has gone under review by the UK government with a view to decreasing its support for solar PV.  With less than a year since its launch, the government has sent shockwaves into the solar PV industry. But how will this impact home-owners interested in a solar PV roof top installation…?

Chris Huhne, the energy secretary, has announced that the government will be looking to reduce the Feed-in Tariff for solar PV installations above 50kW.  This is reportedly to prevent large-scale solar farms, often instigated by foreign investors, which are currently springing up on land across the country and taking funds away from communities and homeowners. A 50Kw installation would use around 250 panels and cover the best part of 400m2. This is well above the 4kW limit often seen for residential installs.

Solarjuice believe that solar panels belong on roof tops as the transmission losses are much less (the electricity transmission losses in the UK grid are between 7-10%) and they do not require any additional land. We also believe that many energy generators also become smarter and more efficient with their energy use as they become more aware of energy.

We predict that there will be a flurry of solar homes springing up the summer of 2011 as homeowners take advantage of the increase in Feed-in Tariff from 41.3p/kWh this April to keep in line with the RPI inflation index. Homeowners will also want to get their installs done before the government turns its attention to residential installations.

It is worth keeping in mind that Feed-in Tariffs have been due to reduce  in April 2012 since the inception of the Tariff. This reduction is to take into account the natural fall in installation costs as panels decrease in price and the UK PV installers become more established and streamline their operations – e.g.by  using the Juice-o-meter Pro which reduces energy prediction and paper processing time.

Energy Price Rises in the UK

What’s happening with UK Energy Prices
ScottishPower announced increases in its standard domestic gas and electricity prices effective from 25th November 2010. Electricity bills will increase by an average of 8.9% (prices for gas will increase by an average of 2%).This will affect 2.5 million households. 
ScottishPower is now the third of the UK’s big six energy suppliers to announce an increase to its prices.
British Gas, who supply electricity to six million homes in the UK, initially followed the lead of Scottish and Southern Energy, (SSE) and raised the price of its gas and electricity by an average of seven per cent.
“The change in prices announced today is as a result of sustained increases in the wholesale energy market, with the wholesale costs for an average Dual Fuel customer up 26% since 31st March 2010. The rising burden of non-energy costs faced by Britain’s energy suppliers, including the cost of meeting government environmental and social programs and the cost of distributing electricity on the national grid, has also placed further upward pressure on energy bills.”

Long Term Trends in Energy Prices
Energy is essential for modern life. It is up there with food and water. And while globalisation has been great in terms of exchange of information, know-how and goods between countries, things like energy (and food/water) are better off being less intimately linked. To ensure worldwide stability energy should be supplied locally (as well as cleanly and sustainably).  But this getting more difficult as fossil fuel reserves deplete and the countries with the main remaining reserves hold onto control.
Renewable energy sources such as solar electric power, solar thermal, wind energy, geothermal power (including heat pumps), hydropower and biomass are the ticket to independent, locally controlled, clean, sustainable energy supplies. Until these technologies and industries become established, energy prices will continue to escalate.  This is not so much due to fossil fuels ‘running out’ but because the easily extracted resources (the ‘low hanging fruit’) have been tapped and because distribution is so uneven.
According to Sir David King, the UK Government’s former chief scientist, the world’s oil reserves have been exaggerated by up to a third, who has warned of shortages and price spikes within years. Their new research argues that estimates of conventional reserves should be downgraded from 1,150bn to 1,350bn barrels to between 850bn and 900bn barrels and claims that demand may outstrip supply as early as 2014.
In the UK, over the last 10 years, electricity prices have been raised an average by 6% per year which is well ahead of inflation.  Over the next ten years Solarjuice estimate that the trend will probably be similar if not worse if the recent announcement by Scottish Power are anything to go by.
This means additional driving force for the shift to localised (decentralised) renewable energy production. The best way we believe for homeowners to power their home is though grid connected solar PV which can now provide 100% of a home’s electricity need (on an average annual basis) if basic energy efficiency is practiced.
We are supporting this industry which we hope will become established and bring solar PV to 1,000,000 homes in the UK. When we are at this level the solar industry and its associated infrastructure is likely to be at a position where it will be able to snow-ball and deliver the latest highly efficient/cheap/green solar roofs to everyone and, hopefully, energy price rises will be a thing of the past.

Solar PV and Solar Thermal Comparison – which is better?

If you are considering going for solar power on the roof of your home, you may be wondering which technology is the best option for you: Solar PV panels or Solar Thermal panels. Although they are both ‘solar panels’ these two technologies are completely different and there can often be some confusion. In simple terms, one meets the need for clean renewable electricity for our fridges, TVs, toasters and kettles, while the other produces clean renewable heat for the hot water in our taps, showers, baths and washing machines.

Evacuated Solar Thermal Tubes

Solar Thermal Evacuated Tubes

Photovoltaic Roof top Modules
Solar Electric PV panels

 

So which is better, Solar PV electric panels or Solar Thermal panels? There’s only one way to find out….

 

 

Solar Electric (2kWp) Providing electricity to your home and to export 

Solar Thermal (4m2) Providing hot water to your home.

Winner?
How much energy does it provide 50% of households electricity demand (on average annual basis for 3-bed gas-heated home) 50% hot water demand (on annual averaged basis) Solar PV
Max installable Can meet 100% of demand on an annual averaged basis (if energy efficiency mesures taken and roof space is available for panels) Can not practically meet much more than 50% of household’s hot water demand. Solar PV
What happens if energy is not used (e.g. occupants go on holiday) Electrical energy is exported through the ‘grid’ so the neighbours can use it (i.e. there is zero waste) Heat energy is wasted as water cools down Solar PV
Install costs £10,000 £3,500 Solar Thermal
Panel roof area 16m2 4m2 Solar Thermal
Government support 41.3p/kWh 19p/kWh (th) Solar PV
Export bonus 3p/kWh (& could be more in the future) - Solar PV
Time to Install 1 day (2 days if roof access is tricky) 1 -2 days draw
Income per year £1000 £350 Solar PV
Income lifetime 25 years(guaranteed) for PV Feed-in Tariff 15 years (guaranteed) for solar thermal RHI* Solar PV
Equipment guarantees 25 years (guaranteed) 5-10 years Solar PV
Equipment lifetime 40 or 50 years 20+ years Solar PV
Equipment payback 10 years (can be lower) 10 years draw
Earning after payback 15 years! 5 years Solar PV
Total profit earned >£15,000! >£1,750 Solar PV
Recyclable yes yes draw
Maintenance Extremely low very low Solar PV
Risks Extremely low Low (panel ‘evacuated tubes’ can reach 120°C Solar PV
CO2 saving/year 1000kg 233 kg Solar PV
CO2 saving/install >40 tonnes >5 tonnes Solar PV

And the winner is?

We think they are both great technologies. We think homes should plan to have both and in the future more and more homes undoubtely will. However, PV does have the clear advantages of:

  1.  Much higher return on investment.
  2.  Much higher carbon savings.
  3.  Hassle free (long life-times and low maintenance requirements).

Having said this, if you roof space is limited solar thermal may be your best bet.

Here at Solarjuice, we obviously favour solar PV. Although we like solar thermal a lot, we are particularly interested in the future potential for solar PV. This is becuase there is large scope in terms of both decreased costs and improved product development and performance through long term future technological developments (solar thermal is a relatively simple technology has pretty much peaked).

* the RHI is “Renewable Energy Incentive” and is the ‘heating’ version of the government Feed-in Tariff. This agreement is still in consultation phase so the solar thermal figures are not set in stone (unlike the PV Feed-in Tariff which is law from April 2010. The final RHI agreement will come into effect from 1st April 2011. However if you do decide to go for solar thermal today, your installation will still be eligible for the RHI (although the income you will get has not been finalised).
