Opportunity
The Enphase Installer Toolkit app faced usability challenges due to inconsistent UI patterns, fragmented workflows, and unclear navigation. Field installers reported inefficiencies in solar panel configuration and design updates, leading to errors and delays. A UX revamp was critical to streamline complex processes, reduce cognitive load, and align the app with evolving technical requirements. The lack of a design system compounded inconsistencies, slowing both development and use. This presented an opportunity to unify the experience through a design+code library, ensuring clarity for installers.

Outcome
Post-launch data showed 15% fewer installation steps due to streamlined workflows and 33% faster design updates from the code library’s reusable components. The design system reduced inconsistencies, leading to 42% fewer QA issues. Installers reported improved confidence in task completion. The improved UI demonstrated enhanced usability, with simplified navigation and contextual guidance reducing training needs.

Hypothesis
Creating a centralised design system with reusable components and standardised workflows would minimise development errors, and accelerate design updates. By aligning the UI with installer mental models and technical needs, the app could improve task completion rates. A parallel code library, developed collaboratively with engineers, would ensure design-to-development fidelity, reducing QA bottlenecks. Testing this hypothesis required scalable components, simplifying navigation hierarchies, and measuring efficiency gains post-implementation.

Execution
The UX revamp began with auditing existing pain points via user interviews and workflow analysis. A modular design library was built in Figma, prioritising atomic components and task-specific templates (site mapping, system configuration). Complex workflows, like panel layout adjustments, were restructured into linear, context-aware steps. Weekly developer syncs ensured the code library mirrored the design system’s structure. Iterative testing with installers validated clarity, while before/after screens highlighted reduced visual clutter and intuitive interactions.

Parth's commitment to delivering good UX is note-worthy. I rarely see anyone dive as deep into consumer thought processes as he does.
Anthony Damien
Director, Solverminds Solutions
An employee I don't have to micromanage. Parth's leadership in creating our design system ensured the process was smooth and efficient. His experience and attention to detail always exceeds expectations.
Medha Kadian
Lead Designer, Enphase Energy
Parth created extremely well-thought user journeys for the interface of an additive manufacturing project here at Oracle. Would work with him again, anytime.
Navneet Kapur
Director, Oracle
I was genuinely surprised Parth has no formal background in product management and growth. His intuition has been proved right time and again, backed by hard data.
