The tech world is increasingly shifting its focus toward sustainability. It’s becoming clear that even the production of everyday gadgets has an environmental impact. As a result, more manufacturers are striving to find a balance between user convenience and environmental responsibility. The Logitech Signature Slim Solar+ K980 is a perfect example of this approach – a keyboard made from recycled materials and powered entirely by light. Today, let’s see whether eco-friendliness can truly go hand in hand with comfort, design, and functionality.

TABLE OF CONTENTS:
Positioning and price
The Logitech Signature Slim Solar+ K980 is priced at €110 in Europe and $100 on Amazon. It’s positioned as a keyboard for business users and professionals. In terms of cost, it sits at the higher end of the mid-range segment – not a mass-market budget option, but rather a product for those willing to pay extra for the idea of responsible manufacturing. The price is slightly higher than that of most wireless keyboards with similar features, and the eco-friendly aspect appears to be the main factor behind this. However, the keyboard doesn’t feel overpriced: it offers solid build quality, excellent usability, and long-term durability – qualities that partly justify its cost.
Package contents
The eco-friendly concept of the Logitech Signature Slim Solar+ K980 starts right from the packaging. The keyboard arrived in a fully cardboard box, wrapped in a fabric sleeve instead of plastic. To minimize paper use, the user instructions are printed directly on the inside of the box, underneath the keyboard. Other than the keyboard itself, the box contains nothing else – simple, minimalistic, and in line with the sustainable philosophy behind the product.

Design and materials
The Logitech Signature Slim Solar+ K980 features a sleek, modern design focused on comfort and ease of use. It’s a full-size keyboard with island-style keys, spaced in a familiar layout that ensures precise and comfortable typing. The overall look is minimalist yet professional – exactly what you’d expect from a device aimed at productivity and long working hours.

The key travel is short, imitating a laptop-style feel – quiet, soft, yet pleasantly springy. An Fn key provides access to additional functions, making it convenient for multitasking or quick shortcuts. Despite its full-size layout, the keyboard is surprisingly lightweight, which adds to its portability and overall comfort during daily use.
The keyboard’s key engraving supports both Windows and macOS layouts – each key includes markings familiar to users of both operating systems.

As mentioned earlier, the main distinguishing feature of the Logitech Signature Slim Solar+ K980 is its focus on sustainability. The device is made of 70% recycled plastic, the cobalt used in the battery is fully recycled, and the concept is completed by a solar panel located above the function key row.

This power method charges the keyboard automatically from any light source, whether sunlight through a window or an overhead LED lamp. As a result, the keyboard does not require any cables for either connection or charging.

Ergonomics
Overall, the Logitech Signature Slim Solar+ K980 is a comfortable keyboard for work and typing, thanks to its low profile and short key travel. The keystrokes are precise and provide clear tactile feedback. However, there are a few ergonomic aspects worth noting.
The main drawback of the design is the lack of adjustable tilt. As someone who is used to keyboards with a more pronounced angle, it took me some time to get accustomed to the relatively flat position of this model.


It is also worth noting the absence of key backlighting – typing in low-light conditions is only possible without visual guidance.
Additionally, the key located between “Z” and “Shift” was a minor inconvenience for me. While this key is necessary for certain European layouts, such as UK English, German, or French, due to the limited number of keys on older keyboard formats, it may feel out of place for users accustomed to standard layouts.

This was my first keyboard with such a key, and I am used to a wider “Shift,” so initially I experienced a lot of accidental presses. However, if you have previously used a keyboard with this layout, you are unlikely to encounter the same issue.

Connections and software
The Logitech Signature Slim Solar+ K980 can be connected to a primary device (laptop, PC, tablet, or smartphone) via Bluetooth. One notable feature is the Easy-Switch function, which allows the keyboard to be paired with up to three devices simultaneously and switch between them using dedicated keys.
The Logitech Signature Slim Solar+ K980 also supports configuration through the Logi Options+ software. Upon first launching the application with the keyboard connected, a demonstration of the device’s features and capabilities is presented.
Through the software, users can configure actions for the function keys and certain other special keys, check which devices the keyboard is connected to, and view information or adjust specific settings. These include using F1–F12 as standard function keys instead of media controls, disabling certain special keys, or relaunching the initial demonstration.

Logitech Signature Slim Solar+ K980 battery life
As mentioned earlier, the Logitech Signature Slim Solar+ K980 is powered by any light source thanks to its built-in solar panel. The manufacturer specifies a runtime of up to four months on a full charge and a battery lifespan of ten years. Verifying these figures is difficult, as it would require keeping the device in complete darkness. During my use, I did not notice any signs of battery depletion.

Conclusions
The Logitech Signature Slim Solar+ K980 is a keyboard that combines a focus on sustainability with modern functionality. It is made from recycled materials and is fully wireless, offering convenience while minimizing environmental impact. The keyboard can be paired with up to three devices simultaneously, allowing for easy switching between a laptop, tablet, and smartphone.

The keyboard has a minimalist and clean design, though this simplicity comes with some limitations – there is no key backlighting and the tilt angle cannot be adjusted. The keys have short travel, making typing comfortable, though it may take some time to get used to. Despite its relatively high price, the Logitech Signature Slim Solar+ K980 gives the impression of a well-built, convenient, and durable device.
