Aurora Solar

Through Pixelfat Design Agency, I worked with solar industry leader, Aurora Solar, to help create the Borealis Design System.

Overview

In 2021, Aurora Solar worked with HelloMonday on a bold rebrand concept—but it wasn’t yet product-ready. I joined via Pixelfat Design to help turn that vision into a scalable system. The result was Borealis, a design system that unified Aurora’s disjointed product and brought the rebrand to life.

Challenges

Aurora Solar had nearly a decade of design debt—fragmented UI, duplicated components, and outdated code. Different product sections used different systems, making updates unreliable and the overall experience disjointed.

They were also preparing for a major rebrand on a tight timeline and needed a scalable, responsive design system that could support product teams and existing users without breaking legacy code.

The challenge: how do you implement a sleek new system into a legacy product in time for a brand launch?

Building the system

We started by establishing design foundations—color, typography, spacing, and elevation—then expanded into core components like buttons, tables, modals, and navigation, all built to be responsive and support light/dark mode.

From there, we created a strategy using style-agnostic components with two theme layers: V1 for the legacy UI and V2 for the new Borealis rebrand.

This approach made it possible to adopt the new system gradually while keeping legacy code intact—and enabled a seamless switch to the rebrand when launch day arrived.

We validated every component with engineering, cross-checked against live product use, and documented everything thoroughly. We also built a custom documentation site to serve as a central resource for designers and developers.

Using the system:
Global navigation updates

Previously, Aurora’s navigation was stitched together over time across different platforms, leading to a confusing and inconsistent experience. It lacked structure, and users often struggled to move fluidly between core areas of the product.

To address this, I collaborated closely with the core product pod to create a systematic, unified navigation experience. While the broader product was still running on V1 styles, we used the new Borealis components to prototype high-fidelity, responsive navigation patterns.

We conducted user testing, gathered feedback, and rapidly iterated. The new design system allowed us to build and adjust quickly, making it easy to validate ideas, stress test the system, and improve the experience with each round.

Eventually, we landed on a flexible, responsive, pattern-based navigation model using the new system. It was a huge win for the company—bringing consistency, clarity, and cohesion to the product—and one of the first tangible signs of what Borealis could enable.

A full enterprise redesign
The Borealis Design System became the vessel for Aurora’s successful brand relaunch—putting their product design on the map and turning a bold vision into a scalable reality.

After nearly a year of behind-the-scenes design system and product work, the rebrand went live with a single theme switch—transforming the entire product UI in just one day. To customers, it looked seamless. Internally, it was the result of deep planning, system architecture, and close cross-functional collaboration.

I created an end-to-end prototype featuring global navigation and DS-compliant key screens to showcase Borealis in action and guide future product vision. The system didn’t just modernize Aurora’s product—it transformed how the company designed and built software moving forward.

Designers moved faster with reusable, responsive components and shorter turnaround times. Engineers had clearer, more consistent handoffs thanks to robust documentation and a shared system foundation.

A successful design system is when designers and engineers can't wait to get their hands on it... Frankly, we took leaps forward because of Patty's invaluable dedication & contribution in the genesis of Borealis, Aurora's design system.
