Opinion Bill Wright, head of energy solutions at The Electrical Contractors’ Association, bemoans the government’s lack of direction in energy policy Brave new world Selling ‘energy independence’ must be the new strategy for PV installers facing a downturn in PV-only customers, argues Steve Pester, BRE y the time you read this, the government will probably have announced its final decisions on how/whether it will support solar going forward. However, it is really starting to look as though the cavalry might be about to arrive in the form of whole-house energy solutions, at least for some in the industry. These solutions are in the form of practical energy storage and clever control products, and are arriving on the scene in droves at the moment. Some of these may be regarded as new and as yet unproven, but others have been rolled out in countries such as Germany for some time. The key message is that no longer will it be sufficient to sell PV in isolation, as a bolt-on investment to a house. The way forward in this ‘brave new world’ is to sell energy independence, offering fixed energy costs for the next 25 years. Solar by itself can offer that to a limited extent, but with the addition of battery storage, the proportion of self-consumption can be radically increased. Small scale heat storage is an even easier sell, with lots of energy diverter products for water heating now being sold to new and existing PV customers. This connection between apparently separate energy systems is really just the tip of the iceberg. Factor in the potential for systems using PV, batteries, electric cars, heat storage, heat pumps, PV-T and top-up heating systems and it becomes clear that building energy systems are starting to merge via intelligent controls, another part of the big up-sell. A new guide on installing battery systems will be available from the National Solar Centre in the next few weeks. B O nce again it’s been rather bemusing month on the energy front as it appears government wants to encourage investment in energy while cutting off support for industry at the same time. Confused? You will be! On the one hand we are facing cuts in subsidies, while on the other the government is intent on increasing the percentage of renewable energy in our supply mix. Surely this is illogical? Instead of building new power stations would it not make more sense to improve the efforts to get people to invest in becoming more energy efficient? It must be cheaper to reduce power consumption than to build power stations. Despite this we’re spending more money on keeping fossil fuelled power stations online than we are in investing in encouraging energy efficiency, or enticing people to invest in renewables. In the short term, combining renewable energy sources with bulk energy storage must be the way to get the best out of the energy sources at our disposal. It would also go a long way to combating the risk of winter blackouts - something that has been given as much press over the summer as the comings and goings of the football transfer window. The UK appears to be on the cusp of an energy storage revolution, and this presents a golden opportunity to invest in research to make the UK a world leader in this area. Let’s grasp it before it becomes yet another opportunity we miss and our competitors take. www.renewableenergyinstaller.co.uk | 15
