# Real-Time Solar Operations with Nevados

Nevados designs solar trackers built for challenging terrain: single-axis systems that follow the sun across uneven ground where traditional flat-row trackers can't go. As their installed fleet grew across multiple sites, they needed a platform that could tell operators exactly what every tracker was doing, in real time, from a single screen.

Nevados is a single axis tracker technology company. Our core product, the TRACE
All Terrain Tracker features articulating technology enabling projects to be
built on up to an unmatched 37% max slope. As the company has grown with over
2GWs in process, the need was clear for a sophisticated operational dashboard to
meet the capabilities of the tracker and our customers' needs.

Nevados contracted with Zentered, who built the Operations & Monitoring
Dashboard for the TRACE All Terrain Tracker, from the ground up, starting in
August 2022. The platform spans the full stack: an MQTT ingestion pipeline that
receives telemetry from every tracker in the field, TDEngine as the time-series
database purpose-built for high-frequency device data, a Fastify GraphQL API
with row-level multi-tenant security, and a React dashboard designed for the
people who run solar farms day to day.

The result is a platform where operators can see the health of an entire site at
a glance: what percentage of trackers are on target, how many zone controllers
are online, whether weather sensors are reporting, and drill down to any zone or
individual tracker when something needs attention. Commands like automatic
tracking, manual wind stow, and remote device reset are available directly from
the dashboard, reducing the time between spotting a problem and acting on it.
The dashboard also gives the user manual control of the array for landscape
maintenance activities for example.

Because Nevados operates across multiple customer organizations, the platform
was designed as a multi-tenant system from day one. Each operator sees only
their sites and their data, with access scoped per organization. As Nevados adds
new customers and new sites, the platform scales without architectural changes.

Not only do customers find it useful, the platform is actively used by field
operations teams across Nevados's growing fleet of solar installations to
actively manage and troubleshoot sites fully remotely, today monitoring over 1GW
of operating Nevados solar capacity across the United States.
