As an example, according to an email seen by Engensa from the energy regulator Ofgem, officials have calculated that the cost of the Feed-in Tariff to household energy bills is less than £1 per year. This agrees with Engensa’s own research found here. In contrast, the UK tax payer pays hundreds of times more than this towards the cost of decommissioning nuclear power stations and looking after the nuclear waste they generate. According to the Government’s own figures, £6.93bn of taxpayers money was given to the Nuclear Decommissioning Authority in 2010-2011, which equates to £260 per household.

As Green Party leader Caroline Lucas MP pointed out in a recent speech, when there are dozens of Big 6 employees working inside Parliament contributing to policy as secondees, and hordes of energy company lobbyists pushing for the decisions they want, it is very important that the Government is absolutely transparent about the costs and benefits of the various options so that the public, not big companies, can decide.

Whilst roof-top solar no doubt has its place, an innovative company based in Scotland and Somerset, SolParks, has looked further afield and brought another variant of solar PV to the UK market – the solar car canopy.

The solar canopy is a structure built over a car parking space with solar PV panels mounted on its top. The canopies bring a number of direct user benefits such as shelter in poor weather, keeps cars shaded from the heat of the sun and can add further to user amenity, by adding in electric vehicle charging points (powered by renewable power, rather than mains) and using LED lighting under the canopies, which can be sensor operated, rather than large street lighting, to provide bright, safe car parking.

The power generated by the solar PV can be supplied direct to the car park owner, or can be supplied to the national grid.

The environmental and user benefits are obvious but also extend to easing legal issues between landlord and solar PV operator.

Elliot Roe of Solparks says “we researched the market for more innovative solutions for solar PV and found car park canopies in both France and USA, where the markets are far larger.   The benefits in the UK are obvious as well and we are innovating even further by using the FITs to enhance the financial benefits for users.”

Solparks is looking for installations of 12 car parking spaces up to 100.   Roe goes on to say “we can provide the installation to a site owner without any cost to them.  We undertake the planning consent, construction works, grid connection and pay for the canopies and solar PV.  The user in return receives discounted power and gains the benefits for their car park users.   The power they can’t use on site is exported to the grid.”

Using the power generated from solar PV on site can save the landowner power costs and can provide a valuable hedge against the threat of rising electricity prices. It also sends a strong, visible, message to customers about green credentials.

Roe says “ we are happy to work with any size of car park owner; however, an ideal customer would be one with multiple car parks. That way the customer achieves wide spread benefit, and the amount of power generated becomes a meaningful contribution to reducing their power bills.”

Solparks feels its solution offers much more simplicity for building owners.  The solar PV doesn’t compromise the core building, no structural surveys or reinforcements are needed and we can also accommodate re-development much more readily.

So why, given all these advantages, is the product limited to 100 spaces in any one location ?  Roe comments that “the changes in the FIT from 1 August make it very difficult, with the FIT alone, to achieve the sorts of levels of returns that are needed to fund a roll-out on a larger scale.  There are other commercial solutions that could be looked at to achieve much larger deployments however and we would be delighted to hear from any potential Solparks customer”

Solparks provides a fully turn-key service to those wanting to purchase rather than lease.  The service includes planning, grid connection, Ofgem accreditation, procurement of all materials and onsite installation. Solparks can also provide an ongoing operation, maintenance, monitoring and reporting service.

The Solparks product comes with a full 25 year warranty over the steel and PV installations plus a 2 year workmanship warranty.

And what of electric vehicle transportation ?    Solparks believes solar car parking can play a large role in the infrastructure needed for electric vehicles – both cars and scooters.    Roe says “adding charging points below the canopies, powered by the sun, is an easy next step and can provide further amenity to customers”.

Given the benefits, we expect to see many Solparks installations starting to appear, and provides large car park owners with another potential revenue stream from an asset that they already own.

Thin film solar modules

I’m particularly interested in certain thin film modules that have now demonstrated their reliability and are starting to gain market acceptance. Some thin film PV companies have been around for over 20 years and many have fallen by the wayside. The surviving companies however are now looking very strong. Their products have now proven themselves in the lab and in the field, and the companies that make them have found ways to reduce production costs and improve efficiency. Thin film has inherently lower manufacturing cost than crystalline silicon, and the potential for efficiency improvement is greater. Therefore I’m confident that over time we will be seeing more thin film get installed.

Storage

A common theme of this years show is storage. Every inverter manufacturer had some kind of energy storage product on show this year. Most solar inverter manufacturers offer back-up energy storage systems that use batteries (typically Lead-acid or Lithium Ion). These provide day/night storage so that solar energy can be used after the sun has set in the evening. Batteries however are not great for storing energy over long periods, so they don’t solve the problem that more energy is produced in summer months than during the winter.

To deal with this problem, Fronius have unveiled their ‘Energy Cell,’ a hydrogen fuel storage system for the home. During the summer, an electrolyzer uses excess electricity from the PV system to split hydrogen from water and store it in a tank. During the winter, this hydrogen is then turned back into useful electricity via a fuel cell. The system has already been a prototype for several years, but this year’s Intersolar showed the system as being almost ready for the mass market. Of course the technology will start out very expensive, but it shows that solar energy can deliver constant power, and its only a matter of time before the cost of the technology falls.

Inverters

We spent some time with SolarEdge who have strengthened their product range and now offer a wider range of inverter sizes, all fully accredited for the UK. They have also been developing their system to be used on larger installations, so people may use them on commercial jobs as well from now in. They also launched a new solar ‘tetris’ game for Xbox Kinect – has to be seen to be believed!

Racking

Hilti have just launched their new flat roof mounting system and it looks amazing. It will make flat roof installations much more secure and manageable, and mean much lower risk of damaging the laminate. Also cool is this robot, used for cleaning solar panels on large arrays. It has 20 moveable sucker pads on the bottom that allow it to hop around cleaning the panels without falling off!

Energy and Climate Change Minister Greg Barker said, “I want to drive an ambitious roll out of new green energy technologies in homes, communities and small businesses and the FiT scheme has a vital part to play in building a more decentralised energy economy.

“We have carefully considered the evidence that has been presented as part of the consultation and this has reinforced my conviction of the need to make changes as a matter of urgency. Without action the scheme would be overwhelmed. The new tariffs will ensure a sustained growth path for the solar industry while protecting the money for householders, small businesses and communities and will also further encourage the uptake of green electricity from anaerobic digestion.”

The new tariffs (below) will go ahead from August 1, 2011 and will apply to all new market entrants.

>50 kW – ≤ 150 kW Total Installed Capacity (TIC) - 19.0p/ kWh
>150 kW – ≤ 250 kW TIC – 15.0p/ kWh
250 kW – 5 MW TIC and stand-alone installations – 8.5p/ kWh

This effectively writes off large scale solar in the U.K. For a government that is attempting to be green this is a huge step backwards.

Greg Barker has ensured that for the same cost there will be less green energy produced. Here at solar feed in tariff we believe this is a terrible move for U.K policy.

Already extremely concerned by the growing evidence for ‘human-caused’ climate change, Prof Mackay’s course taught me some astonishing facts, such as how the amount of solar energy delivered to the Earth is ten thousand times the total amount of energy we use over the course of a year.   He made me realise that human civilisation has a huge amount of work to do to halt its greenhouse emissions, but he also gave me the hope through new technologies, we really can wean ourselves off fossil fuels without impacting our quality of lives too severely.

After a PhD and several years working in solar photovoltaics for a large company in Germany, I returned to the UK and was astonished to find that the Government has extremely low ambitions for solar energy and even more astonished that it is using David Mackay’s analysis, at least in part, to justify this.  At present, the Treasury’s £360m cap on Feed-in tariffs means that support for solar PV at all scales will end by mid-2012 and limit solar PV capacity in the UK to less than 3% of Germany’s current installed base.

When I re-read Mackay’s key book ‘Sustainability Without the Hot Air,’ I find it paints a very compelling argument for solar energy.   Prof Mackay repeatedly points out that solar energy can deliver far more energy than any other renewable energy technology in the UK, as illustrated by the fact that the amount of solar energy we receive in the UK is fifty times the total amount of energy we use, including transport and heating.  At the time of writing, David Mackay singled out two hurdles for widespread solar adoption in the UK; cost and space. It seems as though these hurdles have been interpreted by the Government as insurmountable barriers, whereas careful re-examination of these hurdles using up-to-date figures reveals them to be significantly less onerous than Mackay first assumed.

In relation to costs, David Mackay states ”it will be wonderful if the cost of photovoltaic power drops in the same way that the cost of computer power has dropped over the last forty years.” This is exactly what has been demonstrated over the last 5 years.  Jenny Chase, a solar energy analyst at the research firm Bloomberg New Energy Finance claims “In 2011 we expect an oversupply of solar panels which will put continued downward pressure on system prices.” In his book, David Mackay uses a solar electricity cost of €0.25 per kWh which is 4 times current wholesale electricity costs, but only twice the price of retail electricity, and seeing as prices have continued to fall exponentially since the time of writing in 2008 we can expect this gap to be closed fast.  In fact, the cost of solar energy is falling much faster than that of any other energy technology to the point where it is the expected to compete with unsubsidized retail electricity prices in UK latitudes by 2014/2015¹.  In contrast, the cost of nuclear energy has risen 5 fold since 1970 according to a recent study by Yale University’s Arnulf Grubler².  By supporting the solar industry now, it will soon be able to support itself without subsidy.

Digging deeper into the Government’s original modelling of overall ambition for PV, the Renewable Energy Association has found that a mid-range future fossil fuel price scenario was used which assumes a cost of $80 per barrel of oil in 2020 (which is unlikely considering current prices are frequently above $100).  By using such unrealistic forecasts, the value of investment in solar energy is being systematically undervalued.

The second issue that Prof Mackay raises is with the amount of area required to get large amounts of solar energy.  Whilst there is a vast amount of solar energy available to us in the UK, that energy is disperse, meaning you do indeed need to cover a considerable area in solar panels to cover our electricity needs.  Prof Mackay points out that to get our current electricity (50 units of electricity per person per day) needs would require 200m² per person.  This is a huge amount of area, but it’s important to realise that reaching that target is highly plausible.  The total amount of roof space per person in England is 47m², domestic gardens 114m², and roads and open spaces make up 60m² and 2300m² per person respectively³, so by using a proportion of roof space and a small proportion of open space we could certainly get close to 200m².  Its important to point out that open space does not mean prime farmland, there are many brown field sites that could be put to good use.  Nor do solar panels on open space prohibit the use of that land for other means.  When placed in fields for example, solar arrays can still permit some animal grazing and in other countries, solar arrays are often positioned along motorway banks or as canopies above car parks.

Obviously getting between 100m² and 200m² of solar panels per person in the UK would be a gigantean undertaking and one that would change the look of our country, but this would be just one of a long line of gigantean undertakings that have taken place in our history.  The expansion of organised farming, the construction of road and rail networks, and more recently the construction of electricity and mobile phone grids were all projects that have profoundly changed our country and its appearance.  Just because the task may be large, does not make it impractical.  In the UK we happily resurface 60m² of road per person every 5-10 years.

Solar energy has already proven itself highly popular in the UK.  It is one of the few technologies that can be produced effectively on a domestic scale giving power to families to generate their own electricity.  Solar energy can also be deployed staggeringly quickly.  In 2010 alone Germany installed 8GW of solar energy distributed among over 200,000 individual installations.  That is equivalent to over two nuclear power stations, and there is no way those nuclear power stations could be built so quickly.

There is a misconception that micro-generation does not result in large amounts of energy, but multiplied thousands of times, the amount of energy we can harvest from small solar installations is enormous.  The UK will of course need a balanced mix of different energy technologies, but lets give solar its rightful place alongside the other major forms of energy generation.  As Prof Mackay points out; ‘to complete a plan that adds up, we must rely on one or more forms of solar power. Or use nuclear power. Or both.’

Secure, low-carbon and affordable energy requires investment of £250bn, in electricity alone, if the Coalition is to meet the target of providing 30% of energy from renewables by 2020. This target is in danger of not being met due to lack of action being taken now to invest in a future smart grid that can intelligently connect users and suppliers.

Prof. Roger Kemp from the Institution of Engineering and Technology said: “The report takes a simplistic view of the subject and plays down technical issues. It refers to offshore turbines as having ‘very low running costs’ without factoring-in the potential routine maintenance of large structures in a highly aggressive environment and the lack of significant long-term operational experience in areas like the North Sea.

“When talking about wave energy, the report assumes that the limiting factor in adoption will be economics, while we consider that technical viability could be equally important.

“Demand response will have a central role to play, but the challenge of moving from the current ambition for smart metering to a smart grid with full public involvement is only hinted at.  The need to engage the public is crucial.”

There are many engineering and social issues to be resolved before the optimistic ambitions contained within this report can be achieved.  Its publication coincides with the publication of the government’s infrastructure adaptation report and combined they highlight the extent of the engineering challenges and opportunities presented by climate change.

The solar feed-in tariff works by guaranteeing fixed, premium rates for units of energy both used and fed-back into the grid by small scale pv generators. The government has made it clear that it would like to see households benefitting from this scheme rather that large scale projects. Indeed, smaller scale solar businesses have argued that this change is necessary to ensure that funding goes to those areas which most need capital. While this may be the case, other solar businesses have stressed vehemently that strong tariff support for larger scale projects is essential as it will be those projects whch drive the industry, bring costs down and of course put impetus on technological innovation.

Whatever the differentiation between small and large scale projects made by the Department of Energy and Climate Change (DECC), the essential fact is that reducing the feed-in tariff will harm the UK solar industry by significantly reducing investor confidence in solar projects. All previous research and experience from abroad has shown that a strong tariff system is needed in order to provide investors in solar pv with long term returns on investment protected by government legislation; where these tariffs fall by the wayside, investor confidence in ROI tends to as well. Many within the industry have therefore been lobbying the government incessently, trying to convince the DECC of the need to rethink proposed cuts. Leonnie Greene of the Renewable Energy Association stated that,

“Our view is that the overall ambition is much too low and the government clearly does not understand the strategic importance of solar. We are going back to a scenario where a few wealthy green home owners can install solar, when we want to be widening access to solar, particularly through community scale projects.”

The investment mandate for the Bank is to deliver the Government’s aims on economic growth, facilitate the transition to a green economy and support the UK’s industrial transformation. Much of the focus to date has been on investment in the manufacture of low carbon goods and the rollout of green infrastructure.

Dr Tony Whitehead, Director of Policy at the IET said: “Energy conservation and efficiency should be amongst the first priorities of a sustainable energy policy.

“Energy is set to become increasingly expensive in the future, and to survive in the global market, UK firms will not only need to produce new products, but to produce them at competitive prices. This means driving costs down wherever possible.

“The manufacture of low carbon technology is often seen as a panacea to meet the UK’s carbon reduction requirements whilst at the same time creating a renaissance in UK manufacturing. Yet the manufacture of low carbon goods is not in itself automatically green. A green industrial revolution should first focus on greening manufacturing processes to reduce energy and resource use.

“For the UK to achieve its targets on carbon emissions there needs to be extra support for green manufacturing processes. Energy conservation and efficiency in the manufacturing sector should be a priority for the Department of Business, Innovation and Skills and more widely across government.

“In addition, access to the Green Investment Bank by SMEs will be paramount. SMEs are able to develop and commercialise products rapidly in niche areas. By its very nature, green technology and processes will require innovative solutions; an area where SMEs can develop a competitive advantage for UK plc. SMEs should have priority access to the Green Investment Bank to spur green growth and technology.”
