40 JANUARY 2015 PRO INSTALLER PRO BUSINESS www.proinstaller.co.uk Home grown UK solar is the way forward Britain’s solar power will be cheaper than gas by 2018, according to new industry analysis.The Solar Trade Association (STA) has published new analysis showing the cost of generating electricity from a typical 10MW solar farm in the UK is set to fall faster than many think over the next 15 years. The report, ’Cost reduction potential of large-scale solar PV’, is based on a survey of the trade association’s member companies and their cost forecasts between now and 2030. UK solar soon to be cheaper than gas The report finds that as long as the Government provides stable policy support, it will be cheaper to generate electricity from solar than by burning gas, as soon as 2018. Paul Barwell, CEO of the Solar Trade Association said: “A lot of people still don’t realise just how close solar is to being competitive with gas-fired power generation. UK solar is on its way to becoming subsidy-free, but it is critical we maintain stable Government policy that supports grid connected utility-scale solar as opposed to fossil fuel power stations.” In addition, the study shows that solar will be cheaper than the wholesale price of electricity at some point between 2025 and 2028. The cost of generating electricity from gas, on the other hand, is forecast to increase in real terms over the next 15 years, and will always be more expensive than wholesale power. The results show that the cost of building a large-scale solar farm is set to go down faster than currently estimated by the Government. This is thanks to a growing solar supply chain here in Britain, as well as falling global prices for solar panels and inverters; the equipment that changes the electricity produced by panels into the kind of power used by the grid. Greater ambitions supported by lower costs This research follows a recent report from the Centre for Economics and Business Research (Cebr) about the macroeconomic benefits for the UK of investment in solar, which showed that the UK could provide enough electricity to supply 15% of UK electricity demand by 2030, supporting almost 50,000 jobs. Big solar arrays alone could add more than £25 billion to UK economic output. The global solar market is forecast to be worth over £78bn ($134bn) by 2020, making it a key emerging technology market. The International Energy Agency, Fraunhofer, McKinsey, Deutsche Bank, Bloomberg and UBS have all said how solar has the potential to transform our energy supply. However, the Government recently announced that it was going to close the current Renewables Obligation subsidy scheme for solar farms over 5 MW (about 25 acres), which will slow the falling cost of generating solar electricity on a big scale. Paul Barwell continued: “It is clear that it makes political and economic sense for the Government to back large-scale solar, with the sector’s track record in creating jobs, and producing ever cheaper zero carbon power. This report makes that case even more strongly as our updated costs forecast shows that solar is even cheaper than thought. We just need one final push from the Government to get solar to being subsidy-free; a home grown solution to Britain’s energy crisis.” “It is in the interests of both energy bill payers and the planet to maintain stable support for good quality large-scale solar farms. If we invest now, and make sure the new Contracts for Difference support scheme works for solar, this technology could in 10 years’ time be bringing down energy bills.” WER calculator for the future The VEKA UK Group has unveiled the industry’s only BSI notified and BFRC certified window and door energy performance calculator. Principal Engineer Tim Williams has unveiled the only calculator in the industry capable of providing accurate SELs, DSELs in accordance with the BFRC, and notified U-Values for CE Marking in accordance with EN 14351. The calculator is unique to each fabricator’s products. BFRC rules covering the simulation of spacer bars, changed at the beginning of September 2014, and immediately made results from all existing SEL calculators invalid, and subsequently illegal. The rules stated that all warm edge spacer bars should be simulated as two box models, and all pre-September simplified energy licenses based on the old spacer bar simulation method were made obsolete. Tim explains: “As of 1st September 2014, changes in BFRC rules brought about by updated European standards meant that all previous energy rating calculators immediately became invalid. “CE Marking is a legal requirement for windows and doors, and making false declarations about U-Values may lead to prosecution. I would estimate that less than 40% of the industry is fully covered by every aspect of CE Marking. ‘VEKA UK Group is committed to staying up-to-date’ “VEKA UK Group is committed to staying up-to-date in all aspects of the business. Our new calculator is the only ‘intelligent’ one in the industry, and with the culmination of more than a year’s work to ensure when the 2014 changes were introduced our custom ers would have the tools to stay on the right side of the law. “The new calculator has been officially notified by the BSI for CE Marking and we’ve designed it to provide CE Marking, U-values in accordance with BS EN 14351 for all the major VEKA UK Group products. “The system is bespoke to each fabricator or installer and is personalised depending on which VEKA or Halo systems they use. The resulting Energy Certificate can be given to the homeowner or client as independent proof of a product’s thermal performance. “It offers huge cost savings as it can be used as many times as you like; eliminating the cost currently associated with auditing or notifying each window or door configuration. “Extremely simple to use, the system allows one form to be filled in via numerous drop down boxes that allow fabricators to try all the available configurations, with different glass, spacer bars. It is the only calculator that carries out all the necessary energy rating and U-value calculations from scratch, enabling many permutations of profiles, reinforcement, spacer bars and glass to be used.” The calculator, designed to be ‘future proof’ as it can, will be sent to customers manually, however the long-term plan is for it to be hosted on the website so customers can log in to access their bespoke version.
