Executive Summary

Omnidian provides intelligent software for monitoring and diagnosing residential solar systems across the United States. As installations scaled rapidly, their legacy monitoring infrastructure struggled to process high-frequency data, detect nuanced degradation, and provide actionable root-cause insights.

Closeloop partnered with Omnidian to architect a cloud-native diagnostics platform capable of real-time analytics, intelligent alerting, and scalable monitoring across tens of thousands of solar installations.

The result was a resilient, always-on diagnostics engine that improves uptime, reduces false positives, and empowers both homeowners and service teams with meaningful operational visibility.

Introduction

Always-On Intelligence for Always-On Energy Systems

About Omnidian

Omnidian delivers intelligent software for monitoring and diagnosing the performance of residential solar energy systems across the United States. Their platform helps solar homeowners and service providers detect, analyze, and resolve system issues — ranging from hardware degradation to environmental impacts like shading or snowfall.

As the company scaled to tens of thousands of installations, their engineering team encountered challenges with the legacy monitoring infrastructure — struggling to process high-frequency data in real time and offer actionable root-cause insights.

The Partnership

Omnidian set out to replace outdated, reactive monitoring tools with a cloud-native solution that could ingest high-frequency data, detect issues contextually, and surface meaningful insights in real time.

The company partnered with Closeloop to architect and build a scalable diagnostics platform that could meet the dual needs of homeowners and solar service providers — maximizing uptime while minimizing support overhead.

The Challenge

Solar Performance Monitoring Gaps

As Omnidian expanded its monitoring footprint, the legacy system became a bottleneck for real-time diagnostics and accurate fault detection.

High False Positives

Static monitoring rules could not distinguish between transient anomalies and real failures.

Limited Root Cause Analysis

Teams lacked clarity on whether issues were caused by weather, shading, or hardware degradation.

Slow Manual Triage

Operations teams spent excessive time reviewing alerts and prioritizing incidents.

Poor Customer Visibility

Homeowners had minimal real-time insight into system health and performance.

The Solution

A Cloud-Native Diagnostics Platform

Closeloop worked closely with Omnidian's product and data teams to develop a cloud-native, analytics-driven platform capable of real-time diagnostics, smart alerting, and contextual visualizations — designed to run 24/7 at national scale.

Platform Architecture

Intelligent. Scalable. Always On.

Designed to support thousands of concurrent installations, the platform ingests, normalizes, and analyzes solar performance data from edge to cloud — delivering actionable insights with minimal noise, 24 hours a day, 365 days a year.

Core Modules

The Bigger Picture

The platform now powers monitoring for tens of thousands of solar systems nationwide — and is architected to scale with the growing footprint of residential solar in the United States.

Closeloop delivered not just a diagnostics engine, but a strategic foundation that lets Omnidian grow its customer base without growing its operational headcount.

Why Closeloop

What Made This Engagement Different

Closeloop delivered far more than a diagnostics engine — we delivered a strategic transformation built on deep business immersion, empathy-driven engineering, and a commitment to operational excellence.

Business Immersion

We went beyond requirements gathering — embedding ourselves in Omnidian's operations to understand every edge case, workflow nuance, and data pattern before writing a single line of code.

Tribal Knowledge Digitized

Years of solar operations know-how — informal rules, exception patterns, and escalation logic — were translated into structured, machine-readable diagnostics that the platform enforces automatically.

Scalable from Day One

Every architectural decision was made with growth in mind — containerized modules, API-first integrations, and a cloud-native backbone that scales horizontally as Omnidian's installation count grows.

Co-Creation with Stakeholders

Product, data, and operations teams were involved at every sprint — ensuring the platform reflected real-world feedback rather than assumptions, and delivered immediate adoption on launch day.

Resilient & Fault-Tolerant

The platform was engineered to self-heal — automatic recovery from network outages, graceful degradation under load, and zero-downtime deployments to ensure monitoring never goes dark.

Measurable Business Impact

Every feature was tied to a measurable outcome — fewer false alerts, faster triage, lower support volume — ensuring the platform delivered ROI from the first week of production use.
