Background

As solar operations scale, a centralized O&M system is essential to monitor devices, coordinate tasks, and respond to issues at scale.

Solar Scale Grows

more sites and more devices are creating O&M pressure that manual operations can no longer absorb.

Solar installations grew

~200%

from 2022 to 2023

Cause Lost

$5,720

per year

Operations become distributed and complex

Lost per MW annually due to equipment underperformance in 2024 — up 5× in 4 years

A management system becomes necessary

Industry best practice requires 80% proactive vs. 20% reactive maintenance.

Problem Statement
Operating solar panel cleaning systems at scale introduces several challenges:
Business Challenge
UX consequence

Distributed operations

“Solar plants are spread across different locations, so managing devices is difficult.”

"Operators cannot see device status, task progress, and site conditions in one place."

Delayed response

"In remote or harsh environments, slow maintenance can cause safety risks and downtime."

"Important alerts are easy to miss when they are not clearly prioritized."

Inefficient Monitoring

"As more robots and sites are added, manual tracking becomes slow and inefficient."

"Operators need to switch between many devices, tasks, and statuses, which increases mental load."

Poor data readability

“Without a clear view of operations, teams cannot find problems or make decisions quickly.”

“Too much data on the screen makes issues harder to spot and respond to.”

My Role
In this project, I participated these key duty:
Competitive Analysis

Delve into the marketing research of RV cleaning robots, and field research the persona of operators.

Industrial Designer

Facilitated cross-team alignment and iterative design reviews across a 15+ person engineering team to ensure the O&M system UX aligned with hardware constraints and development requirements.

Ideate
Competitive Analysis

After getting familiar with the currently developed robots, I conducted a competitive analysis to understand the relevant industry landscape.

Empathize
Field Research

To obtain authentic user insights, we conducted on-site research at the power station and studied the manual cleaning workflow of solar panels.

Manual Cleaning Workflow
User Task Map
Key Insights
Operators rely on manual monitoring instead of system support

Leads to high cognitive load

Alerts lack hierarchy and prioritization

Critical failures are overlooked

Workflows are fragmented

Tasks require too many steps

Information is not scannable

Users cannot quickly assess system status

Design Strategy

Based on the insights, I focused on three key dimensions: structure, skeleton, and surface layers.

structure

Simplify Workflow

Reduce steps and streamline task execution to improve efficiency.

Skeleton

Information Readability

Enable skimming and decision-making through structured data visualization.

Surface

Intelligent Assistance

Support operators with alert prioritization and real-time feedback.

Feature List

After aligning, we collaborated with the product manager and developers to finalize the feature list.

Information Architecture

I built the functional architecture based on usage-scenario workflows, using the feature list we organized during the meeting.

Design Solutions
#01 Minimal Task Workflow

Why: Optimize Shorter Operation Steps via In-Depth Competitor Research

#02 Information Readability

Why: Reduce the cognitive workload to ensure safety operation

Readability Enhancement

#03 Intelligent Alert System

Why: Alerts are not prioritized, leading to missed critical issues.

· Information Classification/Tiering
Count the number of alarms of each type, categorized by severity (Tier 1, Tier 2), to provide users with a quick overview of the current alert situation and its overall trend. Different alarm types are distinguished by color coding to enhance readability.

· Real-Time Status Monitoring
Includes alarm status filtering and a device search function, making it convenient for users to find abnormal conditions for specific equipment. It also provides a 'Handle Alert' operation to enable maintenance personnel to respond quickly.

#04 Centralized Device Management

Why: Operators need a unified overview of multiple devices.

Reflections

Designing for B2B requires clarity over aesthetics

I learned that B2B systems should prioritize information hierarchy and decision-making efficiency over visual decoration.

Balancing technical feasibility at a system level

When designing a suite of related products, higher-level system mapping becomes essential to ensure consistency and scalability.

Cross-functional collaboration requires structured alignment

Working with product managers and engineers taught me that alignment needs to be traceable. Clear documentation and structured communication significantly improve collaboration efficiency.

Grounding design in real user contexts

Field research is critical—without it, the interface risks being disconnected from actual user needs and operational realities.

Reusable Workflow

Establish a scalable design system by accumulating reusable visual materials generated through AIGC tools. These assets can be adapted to multiple business contexts, maintaining both creativity and consistency.
