Solar PV Monitoring System — Grid vs Solar, In Real Time
Behind-the-meter monitoring for commercial and industrial rooftop solar owners. Measures generation, site consumption, and grid contribution with Class 0.5S meters — so self-consumption %, performance ratio, savings, and ESG carbon are all measured, not estimated.
Know Exactly How Your Solar Plant Is Performing
Most rooftop solar owners discover months later that their plant is underperforming — by reading inverter dashboards, comparing with EPC commissioning numbers, and guessing at the gap. The Tech OVN solar monitoring system replaces guesswork with continuous, hardware-grade measurement of three things at once: how much your solar plant is generating, how much your facility is consuming, and how much is flowing to or from the grid.
That trio is what tells you the actual self-consumption %, the actual avoided cost, the actual performance ratio, and the actual carbon offset for ESG reporting — instead of inverter estimates that miss derating, soiling, shading, and downtime losses. We don't supply DISCOM net meters; we supply the owner-facing monitoring system that sits behind the utility meter and works for you, not the utility.
What the System Tracks
Six capabilities that turn solar generation data into solar investment intelligence.
Grid vs Solar Split — In Real Time
Continuous measurement of how much load is met by your rooftop solar versus how much is drawn from the grid. Self-consumption % calculated live, not estimated monthly.
Generation, Consumption & Export Tracking
Three independent measurements — solar generation (kWh produced), site consumption (kWh used), and grid export (kWh fed back). The trio that tells you whether your solar plant is actually paying off.
Plant-Level Performance Visibility
Daily, monthly, and lifetime kWh per kWp installed. Performance ratio (PR) tracking. Underperformance alerts when generation drops below expected curves.
Multi-Site Portfolio Dashboard
One dashboard across 1 site or 200. Benchmark plants against each other. Spot the underperformer in a portfolio without site-by-site reviews.
Inverter & String-Level Integration
Pulls inverter data via Modbus / SunSpec where available, combined with hardware-measured generation. Works with any inverter brand — no vendor lock-in.
Savings & ROI Reporting
Tariff-aware savings calculation. CFO-ready reports showing kWh self-consumed × tariff = avoided cost. Carbon savings (tCO2) for ESG reporting.
Who Deploys Tech OVN Solar Monitoring
Owner-side and consultant-side users — never the utility billing process.
Commercial Building Owners
Office buildings, malls, and commercial complexes with rooftop solar — track tenant-allocated solar share, common-area generation, and ROI per kWp installed.
Industrial & Manufacturing Plants
Factories with rooftop or open-access solar — measure load coverage during production hours, identify when grid draw spikes, and benchmark plant-level PR.
Hotels, Hospitals & Hospitality
Round-the-clock operations where solar covers a portion of load — quantify the share, monitor plant health, and report ESG / sustainability metrics to corporate.
Real Estate / REIT Portfolios
Portfolio operators with solar across multiple buildings — single dashboard for performance, tenant allocations, and ESG reporting across the asset base.
Solar EPC Contractors (Post-Handover)
EPCs offering monitoring as a value-add to clients post-commissioning — without taking on monitoring software development themselves.
Energy & ESG Consultants
Consultants verifying solar plant performance, calculating actual self-consumption ratios, and producing M&V reports for clients on net-zero programmes.

Why Tech OVN
What separates a measurement-grounded solar monitoring system from an inverter dashboard wrapped in software.
We Measure It — We Don't Estimate It
Most cheap solar monitoring systems pull only inverter data and estimate self-consumption. We measure all three — generation, consumption, grid — with hardware-grade meters, so the self-consumption % is a measurement, not an inference.
Inverter-Brand Independent
Built to work with any inverter — Sungrow, Huawei, SMA, Solis, Polycab, Waaree, ABB, Delta, others. The meters do the measurement; inverters add string-level health visibility.
Class 0.5S — Same Hardware as Revenue Metering
Self-consumption claims that drive ROI reporting and ESG disclosures should be backed by Class 0.5S measurement, not Class 1.0 inverter sensors. Audit-grade by default.
Built for Portfolios
Single-site dashboards exist everywhere. Tech OVN was designed for portfolios — REIT operators, multi-plant industries, multi-building corporates — across multiple countries on one cloud.
Pair With Energy Monitoring + EV Charging
Solar monitoring is one piece of the behind-the-meter picture. Customers running rooftop solar typically also need full-facility energy monitoring, and increasingly EV charging integrated with solar self-consumption. Same platform, same meters, same dashboard.
