Cost of solar panels will match fossil fuels by 2013

Wednesday, May 13th, 2009

Solar energy will fall in price to match the cost of conventional fossil fuel electricity far sooner than previously expected, the UK’s largest solar company has claimed in a new report. Solarcentury said British homeowners will see solar achieve “grid parity” – the point where solar electricity rivals or becomes cheaper than conventional nonrenewable electricity – by 2013. Most predictions suggest that technological innovation will not bring the price down far enough until 2020 or later.

The company suggested falling production costs for solar panels and increasing conventional electricity costs have brought parity closer. Prices for solar and grid electricity in residential homes are expected to crossover at around 17p to 18p per unit of electricity (kWh) in 2013, followed by parity for commercial solar electricity in 2018.

Last December, the renewable energy analysts New Energy Finance predicted silicon costs – a key material for much solar panel technology – would fall by 31.5% in 2009 compared with 2008 levels. Energy consultants Element Energy, under commission from the government, have also forecast solar PV costs will fall by around half between now and 2020.

Derry Newman, CEO for Solarcentury, said: “When you reach grid parity, you have a watershed moment where the perceptions of investors and consumers shift. People have been programmed to believe solar is expensive and takes a hundred years to pay back, but when parity arrives people realise it takes 8-10 years to payback, and they can then be making money out of it.”

Jeremy Leggett, executive chairman of Solarcentury said, “The feed-in tariff that the government has said it will bring in from April 2010 is vital. A burst of premium-pricing for solar energy, of the kind now on offer in 18 European countries, will stimulate a very fast-growing market.”

Experts said the projections were based on significant assumptions in future energy prices, which have been extremely volatile over recent years – last year saw gas and electricity prices double, but now household bills are falling again.

Ray Noble, solar PV specialist at the Renewable Energy Association, said: “The predicted grid parity by 2013 could be possible if all of the predictions, both in terms of grid electricity prices increasing and reductions in the cost of solar PV, come through. However that’s a big if – any slight changes in the pricing can add further years to this date.” He added that the important message is that even if grid parity slipped to 2016, the moment when solar can compete on cost is not far off.

Chris Goodall, Green party parliamentary candidate and author of Ten Technologies to Save the Planet, warned the grid parity predictions were based on unrealistic price assumptions. “This projection of residential grid parity depends crucially on continually increasing prices of conventional electricity, but I just don’t see any evidence that residential electricity will cost 17-18p a kWh in 2013. The ‘underlying’ retail price of electricity at the moment is no more than 11p per kWh,” he said.

Newman argued that China will continue to take more fossil fuel and believes peak oil will begin to bite in 2013, which will both contribute to rising prices in fossil fuel electricity.

The solar panels revolution begins

Monday, April 20th, 2009

The solar panels photovoltaics industry is the fastest-growing green energy industry in the world. Growth in 2008, announced this week, was fully 89%, notwithstanding deep recession. 2008 venture capital investments in “cleantech” have also been totted up of late.

More than 50 families of green energy technology interest venture capital investors, but in 2008 more than 50% of all their cleantech investment globally in went into solar photovoltaics. There is a solar revolution in the making, and UK plc ought to be part of it – not just for the sake of our competitiveness, but also our oft-stated desire to lead in fighting climate change, and in generating new green jobs to pave the way out of recession.

All this fast growth, globally, is because many governments are now actively building domestic solar industries, using market-enablement mechanisms such as feed-in tariffs and subsidies.

As with all technology, this kind of support is needed if the kit is to be commercialised fast. It needs to stay in place only long enough for the price of solar electricity to be driven firmly below the price of conventional electricity. From that point – “grid parity”, in the jargon – a mass market becomes inevitable.

A recent report by the UK Photovoltaics Manufacturers Association showed that grid parity in Britain may be as close as 2013 for the residential sector, and 2018 for the commercial sector, notwithstanding our cloudy skies. This proximity is another reason for a burst of market-enablement support: we need to build a domestic industry rapidly if we are to meet demand, come the mass market.

Knowing all this, it was with hope in my heart that accepted an invitation from the government to speak at its jobs summit in January, about the scope for a UK green new deal. In March, I attended the Low Carbon Summit in similar mood. There, Gordon Brown called for a global green new deal, using those exact words. Peter Mandelson said that the UK must play a full role in the unfolding green industrial revolution. Ed Miliband said we are in race, both because our competitors are forging ahead, but also because climate change is speeding up faster than expected.

But a few days later, the government cut its main support programme for solar photovoltaics without warning. Scarcely being able to believe what I was hearing, I remonstrated with No 10, and the Department of Energy and Climate Change. I was told that ministers hadn’t known about the decision, which had been taken by DECC officials – wait for this – because solar PV was proving more popular than the other technologies in the programme, and the civil servants wanted the others to catch up. I waited, hoping for corrective action. It hasn’t happened. Job losses have started in solar companies, and still nothing has been done.

Funding for solar PV has been cut before in recent years, only to be reinstated later. The industry in the UK has been put on a kind of stop-start drip-feed. Overseas, in contrast, governments have opted for the kind of reliable commitments that allow businesses to make realistic plans, and hire people, while attracting investors. Its almost as though Whitehall has decided it actually wants to kill this industry in the UK, for some reason. I can’t bring myself to believe in such a conspiracy, but if you did want to kill an industry, in a Yes Minister kind of way, you’d do just what the government is doing.

On 20 April a letter will be delivered to Gordon Brown signed by the National Federation of Roofing Contractors, the Federation of Master Builders, the Electrical Contractors Association, leading architects, and most of the UK solar industry. Essentially, it asks the government to act consistently with its rhetoric on the green new deal, and give the domestic solar PV industry the chance to play a role in the creation of new jobs that this country so badly needs.

It really shouldn’t be this difficult to make reality sit comfortably with rhetoric.

Uk government dragging it’s feet on renewables

Monday, September 1st, 2008

In two years’ time, the UK seems certain to miss one of the core environmental targets of the Blair-Brown years. The Government pledged that 10 per cent of the country’s electricity would be generated from renewable sources, principally from wind farms, but also including tidal and solar panels.

Press releases from the Department for Business, Enterprise and Regulatory Reform (Berr) still boast of the target, which was first promised in 2000 and enshrined three years later in the energy White Paper. And in a statement to The Independent on Sunday, a spokesman for Berr insists that all is well and that: “Estimates show there’s more than enough renewables developments either up and running or in the pipeline to potentially meet the 10 per cent goal.”

But the energy industry does not agree. Senior figures point out that less than 5 per cent of electricity was generated from renewable sources in 2007, up from just over 4 per cent the previous year. This is not, they argue, a sign of rapid progress from a country that that has a far less buoyant renewables industry than Germany and Denmark, although it is far windier.

Despite the impending failure, the Government is pushing for still-tougher targets. The Secretary of State at Berr, John Hutton, is currently consulting with energy companies on plans to generate 15 per cent of all energy – that is, transport fuel and heat as well as electricity – from renewables by 2020 in line with EU ambitions. Responses are due next month, and seem set to recommend that one-third of electricity should come from renewables, to make up for shortfalls in heat and transport. The cost of this is £100bn.

James Vaccaro, managing director of the renewables fund at Triodos, a pioneer in ethical banking, offers one of the gloomier predictions for 2010: that the UK will hit around 6 per cent rather than 10. He recalls a civil servant from the then Trade and Industry Department visiting Triodos’s Bristol offices in 2000.

“The official said, imagine the 2010 target as being part of a pie,” recounts Mr Vacarro. “He said small commercial projects were a small part of the pie, but it would be big renewables schemes that took up the major share.”

Mr Vaccaro countered that there were simply not the available resources in the UK energy market to build the massive wind farms needed to provide the 10 to 15GW to generate 10 per cent of all electricity. Instead, the industry had to be built from the bottom up, with a series of small wind farms of around 10MW that would cost in the region of £12m to £14m. He added that the UK had to get used to the idea of the necessity of these smaller schemes.

It’s a view he still holds. As an example, he points to a British Energy/Amec joint venture to build a 650MW scheme off the coast of Scotland on the Isle of Lewis, rejected in April on the grounds that it threatened the island’s bird population.

Planning is one of the big problems for these wind farms. Although there are hopes that recent changes to the planning process, such as fast-tracking major infrastructure proposals and revamping the appeals procedure, will enable schemes to be approved faster, there is a huge backlog of wind-farm applications that councils have to go through.

Gaynor Hartnell, deputy director at the Renewable Energy Association, says there are “reams of projects” in the pipeline, perhaps as much as 14GW, mainly in Scotland. This would correlate with the Government’s claims that there are “potentially” enough developments to meet the 2010 deadline. However, Ms Hartnell says that delays in granting planning permission – there is also a shortage of qualified planners working for local authorities – means that the UK will not hit the 10 per cent target until 2012.

Juliet Davenport, chief executive of Good Energy, a renewables firm that last week announced interim results showing an 18 per cent increase in turnover to £6.3m, is equally critical of the planning system. And while she remains optimistic that the Government can reach 8 per cent renewables in two years, Ms Davenport has a real planning horror story.

The Ministry of Defence (MoD) has opposed Good Energy’s application to construct a 10MW wind farm, arguing that it could harm its communications ports. However, Good Energy is unable to respond, as the MoD will not provide information on its concerns. Officials say that the relevant documents are classified. “They said that they would not hand them over to us because of the threat of terrorism,” sighs Ms Davenport. “You end up going round and round in circles.”

It is this type of problem, she adds, that has led to the UK having the lowest renewables use as a percentage of all its energy in Europe, bar Malta and Luxembourg. “We’ve got the engineers to build the wind farms, but it’s a difficult market because of the regulatory regime,” she says.

Richard Ford is the UK grid connections manager at Renewable Energy Systems, a company that has developed wind farms for 20 years. What is delaying renewables’ progress, he says, is the difficulty of linking the farms to the National Grid. Faced with a huge volume of applications, the grid will not allow power stations to connect until it has developed the extra capacity required to take the additional power.

Mr Ford would like the grid to manage demand, rather than wait until there is space, since a slot might not be available for 10 years. Planning permission lasts five years in England and Wales, and three in Scotland. As a result, a company can build a wind farm and leave it idle for five or seven years, or it can secure a slot and wait to apply for planning permission, which it might not secure.

“We and others are making applications to the grid before we are certain the developments can be built,” explains Mr Ford. “We would prefer a ‘connect and manage’ approach.”

The Association of Energy Producers believes some progress has been made. Its chief executive, David Porter, points out that just five years ago, renewables projects accounted for only 2 per cent of the UK’s electricity.

Mr Porter’s great worry is that this new target of 15 per cent of all energy coming from renewables by 2020, set by the UK in agreement with other EU states, is much tougher. As wind power is by far the UK’s most advanced technology, with the Scottish government looking into the possibility of a £5bn off-shore grid to connect turbines, it will be the electricity providers that will have the biggest role to play in meeting this target.

He talks of the need to “minimise the cost impact on consumers”, and says a radical overhaul of planning and grid connection is vital “to stand a chance of meeting 2020 targets”.

Already, then, the energy industry is playing down its chances of success at this next stage. Berr can talk up its achievements all it likes, but few in the know appear to believe the department will be able to back this up when the first renewables deadline is reached it in just two years.

PV solar could see big price drop

Tuesday, August 26th, 2008

We’ve been hearing for awhile that solar silicon production is going from scrambling to catch up, to having way too much stock. Now we have an idea how much the prices are expected to fall.

According to information provided to UK’s New Energy Finance by polysilicon and solar-wafer buyers and sellers, solar silicon could drop in price by as much as 43% next year. Additionally, silicon wafer prices could drop 41% – and contract silicon prices dropping by 67% – in 5 years. In New Energy Finance’s report, wafers should retain their value in 2009, but as supply increases, prices could hit less than $6 per wafer, or $1.62 per watt starting in 2011. So just as quickly as prices skyrocketed, they’ll drop again (sound like the housing market to anyone?), which means price parity for solar could be just around the corner, despite various setbacks.

“The first results [from the Silicon and Wafer Price Index] have confirmed that we will be seeing significant falls in prices right along the value chain as the polysilicon bottleneck eases, bringing solar closer to competitiveness with other power sources,” New Energy Finance CEO Michael Liebreich said in a written statement, and carefully pointed out that the research is specific to contract prices, not spot prices for silicon.

We know that companies are interested in manufacturing the in-demand product, but will production slow at all in preparation of this over-supply? No matter what, it’s a sure bet that solar power prices will drop, so we can hope that the (so far) lack of tax credits will not be such a big factor stopping people from hooking up to the sun.

How green is your energy – UK energy special

Monday, August 18th, 2008

Cheap it may be. But is your electricity supplier clean or downright dirty? The argument over coal-fired power – often rated as the filthiest – is now white hot.

When we revealed a fortnight ago how to find the cheapest gas and electricity suppliers, E.ON emerged as one of our best buys. Readers then told us that, instead of saving money with E.ON, they wanted to switch away from the firm to protest against its involvement with new coal capacity at Kingsnorth, site of the Camp for Climate Action this summer.

Electricity has to come from somewhere – and most generation involves CO2 emissions or nuclear waste.

Only Good Energy is 100% sourced from renewables such as wind and waterpower. All companies have been set a government target of 9.1% of electricity from renewables by next March, rising to 15.4% by 2016.

Top of the coal burners is Scottish Power, where 55% of its generation comes from coal, substantially greater than its rivals. Not surprisingly, it also heads the carbon emission table.

EDF is the next biggest coal user at 47% followed by npower at 44% and E.ON at 42%. E.ON’s percentage is likely to rise should Kingsnorth get off the ground.

By contrast, British Gas (Centrica) takes just 18% of its needs from the fuel. It uses its own gas for electricity generation. But for those whose main worry is nuclear energy, Scottish Power’s supplies to its five million customers comes out well at only 1%.

Ecotricity, which figures prominently on green lists, mixes coal, nuclear, renewables and gas in almost equal amounts. The firm concedes it does not have a 100% green fuel mix although it does offer a 100% green supply for those who want it. “We are working towards more renewables. Our most popular tariff is made up of around 70% brown energy. Buying existing green energy, which is what most 100% tariffs contain, does nothing at all to reduce CO2 emissions or increase UK green energy capacity – you simply take something that already exists and have it for yourself.

“Robbing Peter to supply Paul is how we like to describe it. Most 100% green tariffs are a con, because they tell you you’ll reduce your carbon footprint etc, but don’t tell you someone else’s will go up as a direct result. Nothing really changes – it’s just a redistribution of existing green sources.”

Scottish Power says its high coal dependency is due to inheriting coal-fired stations – it owns Longannet station in Fife, one of the biggest in the UK. It is investigating “carbon capture” techniques. These cut down on emissions but are controversial on cost and energy grounds.

It says: “We will spend around £1bn on new renewable projects in the next two years including Europe’s biggest windfarm, Whitelee near Glasgow. Our renewable portfolio will be 10% of our capacity by 2010.”

But those who want pure green energy have to pay for it. A typical 3,300kilowatt electricity consumption costs £484 with Good Energy or £436 with Ecotricity New Energy Plus.

Scottish Power’s Green Energy H2O (it comes from hydropower) costs £354 (the same as its non-green supply) while the cheapest for non-green tariff (British Gas Click 5) costs £295.

Meanwhile Friends of the Earth says the best way to cut carbon is to turn off lights and power.

Why domestic solar panels not domestic windmills

Friday, August 8th, 2008

Rooftop wind turbines are actually net carbon emitters for most British properties, according to new research. Worse still, it appears that even if small turbines became common they could produce only a tiny fraction of the UK’s energy requirements.

The new report is titled Small-scale wind energy and is issued by the Carbon Trust, a quango dedicated to reducing greenhouse gas emissions. The research was carried out with the assistance of the Met Office and consulting engineers Arup.

According to the report’s authors, the most commonly used UK windspeed database is highly optimistic in the case of urban areas. They suggest that one should be wary of believing any figures offered by the wind-turbine industry.

NOABL [Numerical Objective Analysis of Boundary Layer] is a public domain reference dataset used widely in the UK wind industry … analysis by the Met Office suggests that NOABL tends to … over-predict the amount of power it is possible to generate with small turbines in built-up areas.

The [free from the government biz department] Wind Speed Database (created using the NOABL model) does not reflect the effects of urban areas (the wind speed values are representative of open, level terrain.

There are a variety of sources of wind speed and direction data available. All of these data types have limitations, either in terms of their temporal or spatial extent, or in terms of their representativity of urban areas. There are a number of proprietary systems used by the wind energy industry. Tools such as WindFarmer, WindFarm and WindPRO do not include any functionality designed specifically for siting turbines in urban areas.

The researchers go on to model the expected yields of small wind turbines using a more realistic Met Office database which you have to pay for, rather than the free one, and they allow for the serious reductions in windspeed to be found close above urban rooftops. The results make depressing reading for microgeneration fanciers.

Because small turbines are mounted at relatively low heights, their mean hub height wind speeds may be close to their cut-in speeds. The implications are that, for long periods of time, a small turbine may not operate at all, or if it does operate (and visibly spin), it may not generate much electricity.

Practically speaking, small wind turbines require locations which are open, exposed and experience high wind speeds, which generally tend to be found in rural areas. Because the output to be expected from urban turbines is so low, the cost of the resulting energy is very high. According to the Carbon Trust analysts, electricity prices would need to be double their present levels before any urban turbine could earn its keep. Even if electricity soared to eight times its current price, economically viable urban turbine sites would still be a rarity.

Practically no urban sites have costs of energy below 25p/kWh. At 100p/kWh, the energy that could be generated at rural sites is about nine times that of urban sites; i.e. the split is 90 per cent rural to 10 per cent urban.

Eco-friendly green homes save energy

Friday, July 25th, 2008

UK households could cut their domestic gas bill by a total of £4.6 billion annually by employing energy saving, eco-friendly measures, a new study suggests.

British Gas claims that its ongoing Green Streets Trial has seen some participating families cut the amount of gas they used by 50 per cent and that other households reduced their total energy use by 30 per cent.

This was achieved by fitting solar panels as well as energy efficient boilers and light bulbs.

Phil Bentley, managing director of British Gas, commented: “For every £3 we spend heating our homes £1 is wasted because of poor insulation.
“And whilst strict standards on new build are needed, most of the energy being consumed is in the ageing homes we live in today.”

Participants in the study were granted a budget of £30,000 per household to spend on energy-efficiency fittings for their homes.

A hot summer for solar panels sales

Tuesday, July 22nd, 2008

Hot weather, rising domestic energy bills and concerns over climate change have conspired to make life easy for companies selling solar energy systems to householders. However, according to Cambridge UK based analysts, CarbonFree, some parts of the domestic renewable energy market are, themselves, starting to overheat with the benefits systems being oversold to householders.

Already a few renewable energy technology installers have made front page news in local newspapers for all the wrong reasons as customers discover that either promised benefits do not materialise or in some cases the systems do not work. According to CarbonFree the number of dissatisfied customers could increase this coming winter when the performance of solar energy systems fall. In addition, it believes that if the price of oil falls some householders, who were persuaded to buy at the peak of the market, may question the cost effectiveness of their new heating systems.

According to CarbonFree the problem of over selling is particularly acute with hot water solar installations, as the entry point into the market for small and relatively inexperienced installation companies is very low in terms of equipment and staffing costs. However, a report based on research CarbonFree carried out into microgeneration identified well-designed and professionally installed solar hot water heating as a relatively cost effective solution with a realistic payback period.

The report, “Householders as Energy Providers” catalogues a range of technologies that are deployed within microgeneration projects and describes government schemes vendors can use to increase take up of renewable energy equipment.

CarbonFree has identified energy storage as an important component in both microgeneration and large scale renewable energy installations. In its report “Watts In Store – Storing Renewable Energy”, CarbonFree predicts a growth in demand for equipment that can both even out short term peaks and troughs in solar and wind energy availability and also store energy during the summer for use in winter months. The report highlights “road energy” as an important technology in the energy storage market. In road energy systems, heat energy is taken from highways and airport runways during summer months and stored in aquifers to boost the performance of ground source heat pumps during the winter.
