Meet the material that’s rewriting the rules of solar power, and bringing cleaner, cheaper energy closer to everyone, no roof required.
Perovskite is being called the wonder material of solar energy, and for good reason. Originally discovered in the 1800s, it’s only in recent years that scientists realised how extraordinary it could be for renewable energy.
Perovskite is a crystal-like compound that can absorb sunlight far more efficiently than traditional silicon. It’s lightweight, flexible, and significantly cheaper to manufacture, a combination that could completely transform how we produce and use solar power.
According to the BBC, this breakthrough could make solar energy “as cheap as fossil fuels” while unlocking new ways to power our homes, including balcony solar panels for UK flats and apartments.
The UK is at the heart of the perovskite revolution, with two standout innovators: Oxford PV and Power Roll.
Oxford PV, a spin-off from Oxford University, has achieved a record-breaking solar efficiency of over 30% by layering perovskite on top of silicon. This “tandem” approach allows small, lightweight panels to capture more sunlight than ever before.
Power Roll, based in Sunderland, is taking a different route, developing flexible solar films that can literally roll onto curved or vertical surfaces. Imagine window frames, balcony railings, or even the side of your building quietly generating power throughout the day.
As the Financial Times put it, this is “a race to reinvent solar energy.” And for people living in flats, that race could finally bring renewable energy within reach.
Traditional solar panels were built for large rooftops: heavy, rigid, and often expensive to install. That’s why so many people in flats or rented properties have felt left out of the clean-energy movement.
Perovskite changes that completely. Its unique properties make it ideal for balcony solar panels and urban environments, because it’s:
✅ Lighter and thinner: easy to fit on balconies, railings, or walls.
✅ More efficient: captures sunlight even on cloudy or low-light days.
✅ More durable: resists heat, moisture and cracking better than many flexible alternatives.
✅ Direct-to-source: power is generated and used right where you live, reducing energy loss in transmission.
In short, perovskite solar allows energy to be produced closer to where it’s consumed. Cutting waste and giving people genuine control over their power.
At SaveOnWatts, we believe renewable energy should be for everyone, not just homeowners with big roofs. Balcony solar powered by perovskite makes that vision possible.
For the first time, you can have:
This is solar energy made simple, affordable, and empowering... no roof required.
Perovskite isn’t just another solar material, it’s a whole new era of renewable technology. It means solar power that’s:
Smarter: Designed to work efficiently in the UK’s variable light conditions.
Smaller: Flexible enough for city living, balconies, and high-rise homes.
Stronger: Built to last longer, even under tough weather conditions.
And as the technology matures, the costs will drop, making renewable energy even more accessible.
Imagine stepping out onto your balcony, knowing it’s quietly generating clean, affordable energy for your home. That’s not some far-off dream, it’s the reality perovskite is bringing closer every day.
At SaveOnWatts, we’re watching this revolution closely because it supports everything we believe in:
Empowering everyone to save money, take control of their energy, and help the planet no roof required.
Big energy’s had their turn. Now it’s yours.
