Electronic Shelf Labels

It’s time to modernize physical retail. Solar-powered electronic shelf labels (ESLs) are a sustainable, cost-effective solution that can improve consumer experiences and streamline daily operations.

At Exeger, we have invented a solar cell that converts all forms of light into electrical energy, enabling endless battery life for low-power devices such as ESLs. Our solar cell, called Powerfoyle, is environmentally friendly, offers unmatched design options, and is durable for a long product life.

Cost-Effective and Maintenance-Free

ESLs are an essential part of efficient and connected stores. Digital displays enable accurate, easy-to-read pricing and product information. Automated displays can also reduce pricing errors, increase customer confidence and increase store profitability. However, the hassle and cost associated with battery replacements have been a limitation to widescale implementation. Solar-powered ESLs are the answer. Thanks to endless clean energy, they offer a maintenance-free solution.

By eliminating the need for battery changes, ESLs powered by Powerfoyle also have a lower total cost of ownership, driven by savings in labor and resources. Since solar-powered ESLs constantly charge using surrounding indoor light, staff can focus on things like customer service instead of wasting time on paper label replacements or battery changes. With the benefit of clean energy, ESLs are a more sustainable option and appeal to customers who are looking for an environmentally-friendly shopping experience.

ENDLESS energy Using Indoor Light

Powerfoyle solar cells stand out for their exceptional performance. We offer two versions of our solar cell: Powerfoyle Indoor and Powerfoyle Hybrid. Each version is optimized to ensure maximum power output based on the light conditions. So even in low, indoor light the solar cell generates as much power as possible, as it is designed especially for that environment.

Powerfoyle-powered ESLs also prepare for the next generation of digital retail solutions. Without the restraint of battery drain, Powerfoyle-powered ESLs can offer more attractive and smarter digital features, such as inventory tracking, personalization, and dynamic pricing.

Designed for the Future

When it comes to Powerfoyle’s design, anything is possible. Our solar cell is fully customizable, and can be produced in any size, shape or texture. These design capabilities allow Powerfoyle to be seamlessly integrated into any product.

Durable and Long-Lasting

Powerfoyle is designed for everyday life. It is durable and has undergone extensive testing to ensure it can hold up to the wear and tear that comes with high traffic operations.

Customization Options

Thanks to Powerfoyle’s design options, your ESLs can look attractive and blend in with your brand aesthetic. For example, the solar cell can look like leather, brushed steel or fabric. Your logo or other graphics can also be printed directly onto the top cell layer with minimal effect on performance.

Industrial Scale Production

With industrial-scale production at our two factories in Stockholm, we can cover all your store needs. We can produce up to 2.5 million square meters of Powerfoyle annually.

SUSTAINABle Solutions for Smarter Shopping

As the Internet of Things expands at an incredible rate, so does the need to find alternative energy sources for these connected devices. Based on current market growth, an estimated 78 million batteries from connected devices will be discarded globally every day by 2025 (Source: Europe EnABLES project). With solar-powered ESLs, renewable energy offers a more environmentally friendly alternative to batteries and demonstrates your company’s contribution to a sustainable future.

Exeger’s commitment to sustainability is evident in everything that we do. Unlike many other solar cells, Powerfoyle is non-toxic, made using easily sourced raw materials. Our production sites in Stockholm, Sweden use 100% renewable energy and generate no toxic emissions.

Exeger has joined forces with VusionGroup to create light-powered digital shelf technologies. EdgeSense™ with Powerfoyle™ is a solar-powered electronic shelf label (ESL) solution that sets a new standard for retail digitalization, ensuring that stores are smart and sustainably powered for today’s demands and the innovations of the future.
