Overview

Jolt was designed to streamline coordination across the fragmented solar ecosystem by bringing installers, suppliers, and project stakeholders into a unified marketplace system.

As Product Designer, I translated early-stage marketplace concepts into a structured architecture — defining listing models, messaging systems, transaction workflows, and multi-role dashboards that supported pilot validation and stakeholder alignment.

The goal was to test whether consolidating discovery, coordination, and transaction into a single environment could reduce operational friction and accelerate project execution across distributed teams.

Problem

The solar industry operates through fragmented coordination and manual processes.

Installers source materials through disconnected supplier networks.
Communication occurs across email, phone, and spreadsheets.
Transactions lack structured visibility and centralized tracking.

This fragmentation introduces inefficiency, misalignment, and delays across project lifecycles.

The challenge was not simply building a marketplace — it was architecting a scalable coordination layer capable of supporting multiple user roles, structured communication, and transactional workflows within a single system.

Approach

I structured Jolt as a multi-sided marketplace architecture composed of three foundational layers.

Marketplace Discovery Layer

Designed structured listing models enabling suppliers to surface inventory and installers to filter based on project requirements and constraints.

Communication Layer

Built integrated messaging workflows allowing stakeholders to coordinate directly within the platform, reducing reliance on external tools and improving visibility.

Transaction Layer

Defined quote submission, negotiation, and transaction approval flows supporting transparency and structured collaboration across parties.

Guiding principles:

  • Design for multi-role clarity

  • Reduce operational fragmentation

  • Establish scalable listing and messaging patterns

  • Support rapid validation through structured prototyping

The system was intentionally architected to enable iteration while maintaining clarity across roles and workflows.
