How far away are we from ‘clear’ solar panels?
New skyscrapers are being built in London and other major cities all the time, with rooftop solar panels now being included as standard – excellent news for anyone concerned about the environment. If solar panels could be integrated into entire buildings however, the amount of energy that could be generated, and the consequent reduction in greenhouse gas emissions, could be a giant leap forward in the battle against climate change. In this blog, we look at how close we are to achieving that goal.
Cambridge-based startup Polysolar is developing see-through panels that can be designed into buildings, greenhouses and canopies. It has already utilised the new technology at two Sainsbury’s petrol stations and a canopy at the Barbican Centre in London, and its latest installations include a transparent solar bus shelter in the centre of London’s Canary Wharf. However, research funding and green subsidy levels will dictate how quickly these panels become a widespread mainstream commodity.
To make this technology more affordable, government subsidies and investment in green technologies are necessary. Despite breakthrough innovations in creating a clear solar panel, production on a large scale is restricted by technological limitations and high costs.
The UK government could help by investing in greater research and development, with the result that once a mass production technique is achieved, it could be sold to other countries and companies around the world. Widespread uptake of the technology would further drive down costs and could make this practice an industry standard in the not too distant future.
However, such a radical transformation of energy generation is unlikely to go unchallenged by existing fossil fuel energy companies. Businesses with a focus on centralised distribution may increase funding of political lobbying to stop or restrain government support for such innovation for their own self-preservation.
Regardless of the challenges, once ‘clear solar panels’ can be readily integrated into the windows of our houses, workplaces, and leisure centres, our capacity to generate clean energy will be enormous. Clear solar panels will bring a huge change not only to local communities but also to our planet by massively reducing the amount of greenhouse gas emissions that come from our buildings .
