What we build

Platform capabilities

The capabilities below are based on confirmed engineering work in adjacent domains (BESS, inverter integration, telemetry pipelines) — see the live demo below.

Portfolio monitoring dashboard

Multi-site overview with live generation, performance ratio, specific yield and capacity factor per plant. Configurable alert thresholds and deviation detection.

Generation analytics

Irradiance-corrected performance ratio, clipping detection, soiling loss estimation and long-term degradation trending — all surfaced in an operator dashboard.

Inverter integration

Direct Modbus TCP / IEC 61850 / SunSpec polling from string inverters and central inverters. Real-time power, voltage, frequency and fault codes per device.

Alert & alarm system

Rule-based alerting over inverter telemetry, grid events and weather-corrected production targets. Configurable severity tiers, escalation and notification delivery.

SCADA integration

OPC-UA and Modbus SCADA bridges for control-room integration. Live topology diagram with energy flow and per-string health visible at a glance.

Yield & revenue reporting

Automated daily, monthly and annual yield reports. PR trend charts, loss waterfall analysis and export for energy settlement systems.

Engagement deliverables

Protocol-native inverter integration

Direct Modbus TCP, SunSpec or OPC-UA polling from string and central inverters as installed on site. No vendor middleware required.

Portfolio and per-string dashboard

Multi-plant overview with per-string performance, irradiance-corrected PR, soiling flags and yield against budget — configured to the site layout.

Alarm rules tuned with O&M team

Alert thresholds defined with the site's O&M team during commissioning. Escalation tiers and notification delivery configured before go-live.

Yield and performance-ratio reporting

Automated daily, monthly and annual yield reports with PR trend charts and loss waterfall. Export-ready for energy settlement and O&M contracts.

Historical data retention and export

Time-series data retained in TimescaleDB with a configurable retention horizon. CSV and REST export for finance, compliance and third-party analytics.

Runbooks and handover documentation

Operator runbooks, protocol configuration files and system documentation delivered at project close. No proprietary lock-in.
