Bendable Tech Could Make Solar Panels More Affordable: 'Exceptional Durability'

Breakthrough in Solar Technology

Korean scientists have made a significant advancement in solar technology by developing bendable solar panels that remain functional even in humid conditions. This innovation tackles one of the major challenges associated with perovskite materials, which are known for their potential to reduce the cost of solar production compared to traditional silicon panels. However, these materials have historically been vulnerable to water damage, limiting their practical use.

To overcome this issue, researchers from Korea's materials research institute introduced protective layers both above and below the panel's energy-capturing core. These barrier materials enabled the panels to operate effectively at 50% humidity levels. After nearly 3,000 hours of use, the panels maintained an efficiency of 85%. They also demonstrated remarkable resilience, retaining 96% of their power output after 10,000 bending tests and preserving 87% of their capacity during extreme mechanical stress tests.

This development was achieved through a collaborative effort involving Korean universities, Switzerland’s University of Fribourg, and the Korea Institute of Materials Science (KIMS). The team dedicated years to refining the materials and manufacturing techniques necessary to make the technology commercially viable.

Impact on Solar Production

The significance of this breakthrough lies in its potential to make solar technology more affordable. Traditional manufacturing processes required costly climate-controlled environments or protective gas settings. With this new technology, high-efficiency perovskite solar cells can now be produced in ambient air without the need for expensive equipment, leading to a substantial reduction in production costs.

Dr. Dong-chan Lim, the lead researcher at KIMS, emphasized the importance of this development, stating, "With this technology, it is now possible to manufacture high-efficiency perovskite solar cells in ambient air without costly equipment, significantly reducing production costs." He also highlighted the exceptional durability of the flexible devices, suggesting they could be ideal for applications in wearable electronics and vehicle-integrated solar power systems.

Potential Applications

Bendable solar technology has the potential to power a wide range of products, including clothing, backpacks, and vehicle surfaces. The technology has already been successfully scaled to industrial production methods, demonstrating its readiness for mass manufacturing.

Solar energy plays a crucial role in reducing air pollution, which can have harmful effects on human health. Each new solar installation helps decrease reliance on power plants that emit harmful particles into communities. Bendable panels could accelerate the adoption of solar energy by fitting into spaces where rigid panels would not work.

Future Outlook

Scientists anticipate that commercial production of this technology will begin within several years as manufacturers adapt existing facilities to implement the new process. Installing solar panels is considered one of the most effective ways to reduce home energy costs, potentially bringing them down to or near $0.

The calculation to find out if YOU should install solar panels on your roof

Solar panel installations are booming – up 22 per cent in the first six months of the year, and there are now more than 1.8 million households with them.

But with panels costing thousands of pounds and most months in Britain struggling to match this summer's sunshine, will they save you money? Before signing up, there are some crucial things to consider to work out how long it will take for the cost to pay off.

Is your roof suitable?

The panels can be used to power your home, saving on your electricity bills. You can also be paid for exporting energy back to the grid, via a Smart Export Guarantee tariff.

The recipe for success requires your home to be suitable for them, with

the size of your roof and the direction it faces key. Your roof's size determines how many panels you can get, which will decide the potential output of your system.

A system's energy generation is measured in peak kilowatts (kW), with an average system for a three-bedroom house delivering 3.5kW, according to the Energy Saving Trust.

The amount of roof space required depends on the efficiency and potential output of the panels you get. For example, it could consist of ten 350 watt panels, covering about 20m2 of the roof.

Ideally, your roof will be south-facing. East or west-facing roofs will also work, but it is not recommended to install panels on a north-facing roof. A pitched roof is preferable, but a flat roof can work. Panels can also be installed on a shed or garage.

A system facing east or west generates 15 to 20 percent less energy than one facing south.

A 3.5 kW system in southern England could produce 3,000 kWh annually. This could be worth £560 a year, by saving £320 on bills and earning £240 from export payments.

How much will I earn?

The crucial calculation involves dividing the cost of the system by your annual return to see how many years it will take to pay it off.

You need to know: how much panels will cost, the energy you can generate, the estimated annual saving on your bills and the projected annual return from exporting.

For the three-bedroom example above, the panels would cost about £6,100, while the total annual return is £560, giving a pay back time of 11 years.

Returns will be influenced by some other factors. If you are at home all day, you can potentially save more on electricity bills by using power when it is generated.

On the flipside, this may mean you earn less from selling to the grid. Energy Saving Trust figures show how this and where you live can mean payback periods vary.

For someone in London who is at home all day, it would take ten years for solar panels to pay off, whereas if they were only at home after 6pm, it would take 12 years.

In Manchester, this would be 11 years and 13 years, respectively, while in Stirling it would be 12 years and 15 years and in Belfast 13 years and 21 years.

The Energy Saving Trust has a free solar panel calculator at pvfitcalculator.energysavingtrust.org.uk. Enter your address, along with property and household details, and it will tell you the cost, return and payback period.

Why are they so popular?

For early adopters, the environmentally friendly aspect of panels was a key driver, but now it is mostly about saving money and reducing exposure to volatile electricity costs. Installer Gareth Jones says his company, Carbon Zero Renewables, has seen a surge in requests since the energy price spike in 2022. He says: "You can take back an element of control with panels, otherwise you're at the mercy of energy companies."

How much will it cost me?

It depends on the size and type of system, how easy it is to access your roof and whether you need to do any other work on the roof.

While the Energy Saving Trust says the average domestic 3.5kW solar panel system costs around £6,100, others give higher figures. Which? says a 3kW system costs £7,020 to £11,250 to install, while a 5kW system is £11,650 to £16,300.

The exact figure will depend on the make and efficiency of your panels, as well as the cost of the installer, which varies across the country, but typically accounts for between ten and 20 per cent of the price.

Panels are now cheaper and more efficient as technology improves. Martin Aylward, of EDF UK, says: 'Domestic solar technology has come a long way in the past decade. A typical solar panel's power output has jumped from 250W to 450W and overall system peak production has increased from 3.5kW to 5.5kW in the past decade.' Installation costs have fallen by 4.5 per cent in the past year.

Batteries are an optional part of a system, but they can help homes save more money as they can store excess electricity to be drawn on when you need it.

A battery for a three-bedroom home costs £2,500. A replacement battery is usually needed after 15 years.

Are there any grants?

Low-income households receiving certain benefits, including Universal Credit, may be eligible for the Government's Energy Company Obligation 4 (ECO4), which covers up to 100 per cent of the installation cost. Go to: eco4.org.uk/

The Warm Homes Plan grants low-income tenants or homeowners and recipients of means-tested benefits up to £30,000 towards energy improvements including solar panel installations.

The government-backed Smart Export Guarantee (SEG) allows households to sell electricity they generate and do not use back to the grid.

Energy suppliers offer their own SEG tariffs, but to qualify, you'll need a smart meter and proof that your installation and installer are certified by the Microgeneration Certification Scheme (MCS).
