Despite the uncertainty surrounding the UK solar photovoltaic industry, the fact remains that with the feed-in tariff in place in any form, there will continue to be a market for investors. The coalition government has announced that they will be changing the feed-in tariff to focus on smaller scale, roof-mounted solar installations to the detriment of large scale solar farms.

However, for those installing solar pv panels, there are still very healthy returns to be had from the payments which come from the feed-in tariff scheme something which Eco Environments believe is the main catalyst behind the growth of the industry in the UK.

There is a very evident media focus on climate change and the resulting political rhetoric which follows and also, a growing culture of awareness in green energy, recycling and the need to dramatically reduce carbon emissions on a domestic level. David Hunt of Eco Environments believes however that the growing interest in installing household, roof-mounted solar panels comes not from a desire to be environmentally friendly but from the commercial advantages which come as part of the feed-in tariff.

Hunt believes that,

“Most people are looking at it now domestically because they are going to get two or three per cent on an ISA or out of the bank account, but with the solar they can get 15 per cent”.

At a time where it is very hard to find savings accounts offering attractive interest rates and there is a worldwide lack of confidence in traditional investment opportunities in the stock market, it is perhaps unsurprising that the great majority of people look to install solar panels for purely financial reasons. After all, while it is the government’s business to meet carbon reduction targets and appear to be environmentally friendly, it is the homeowners business to dramatically reduce their utility bill while hopefully creating a very steady revenue stream on the side

Cambridge based solar technology company Polysolar has developed a hi-tech photovoltaic glass which could be used at next year’s Olympic Games in London and also the 2022 FIFA World Cup in Qatar. Polysolar’s transparent PV glass has been designed for use by architects in windows, cladding and glass structures as a way of generating green energy. The glass is already in use in other countries and is able to generate 100w of energy from each pane of glass making it an effective way of generating clean energy from wall and roof space.

Explaining the idea behind the glass, Hamish Watson the founder of Polysolar said,

“Our product is different from any other solar panel on the market, because it can be used as a building material, making it a highly cost effective integral part of the building. Unlike traditional solar cells, which need to be southward facing, the glass can be positioned anywhere, so is more flexible for large scale architectural and engineering projects and hence it generates a higher yield.”

Importantly, Polysolar’s glass has received MCS certification for the UK feed-in tariff. This means that where installed, landlords will be able to generate revenue from the energy which the panes generate which is used or fed back into the national grid. The Ploysolar product will also have the attraction that where installed, property owners will see massive reductions in their electricity bills. Aside from the obvious financial benefits, Hamish Watson is well aware that the green credentials of solar pv technology will be very welcome by event organising committees.

“Our PV glass has generated a lot of interest and we are in discussions to install it at the 2012 Olympic village, where it could be used to help generate power for information displays across the site. We have also had early discussions with the organisers of the 2022 World Cup and the developers of London’s Walkie Talkie building – both projects are obviously quite exciting for our company.”

Wadebridge, sitting in picturesque North Cornwall is a sight to behold with its abundance of solar panels furnishing rooftops with not inexpensive solar pv equipment. This concentration of roof mounted solar pv panels in Wadebridge has not occurred by chance, rather it is the result of a project designed to make the Cornish town the first in the country to be powered by solar energy.

The project, known as the Wadebridge Renewable Energy Network or WREN is a scheme which hopes to meet self set targets of generating a third of its electricity from solar by 2015. By hooking into the government’s feed-in tariff mechanism WREN has hoped to install projects throughout the town and of course off sets costs through the tariff scheme. With bold targets of installing 7MW by 2015, Wadebridge could become a potential beacon for wholesale community solar projects in the UK but of course also reflects the fickle nature of an industry completely reliant on government tariff legislation.

The feed-in tariff enables small scale solar pv generators to generate revenue for the electricity produced and consumed by solar projects. Through the feed-in tariff WREN has projected that it could potentially generate £2.5million over the project’s 25 year life span with the money being reinvested back into other green energy projects. Recent announcements of the cuts to be made to the tariff could prove detrimental to Wren’s plans and the potential for healthy yields over the course of the project.

Stephen Frankel, the founder of Wren explained that,

“In contrast to recent green announcements, their success could be limited due to Government proposals to restrict the size of solar installations in the UK”.

“Proposals to limit the Feed-in tariff, payment for clean electricity, to small 50kWp systems means the town wouldn’t go ahead with mid to large scale projects which would bring much needed income into their community fund and help the town meet their renewable energy targets”.

With the government’s consultation on proposed cuts to the feed-in tariff drawing to a close, solar industry members are anxious to see how drastic changes to the tariff will be. Many involved within the UK solar industry are fearful that reductions in the solar tariff of up to 70 per cent for pv energy generators over 50MW. Whatever the nature of changes to the solar feed-in tariff mechanism, it is more than likely that the worst affected will be large scale installations such as the large scale solar farm sites which were looking to tap into tariff revenue.

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.”
