Solar Power Monitoring System — PV, Grid, and DG on One Dashboard

Measure Every Source. Prove Every Saving.

A solar monitoring system measures generation, grid import/export, and (optionally) diesel generator output across the same dashboard — letting facility owners verify solar performance, calculate true self-consumption, justify storage, and comply with net metering. Tech OVN's Titan smart meter delivers bi-directional metering on every source with WiFi or Ethernet to the cloud.

Why Inverter Monitoring Isn't Enough

Solar inverters report what the inverter sees: DC input, AC output, error codes. They don't see grid import, they don't see diesel runtime, and they don't see what the building actually consumes. That makes it impossible to answer the questions that matter most:

  • • What percentage of solar generation is being self-consumed (vs exported)?
  • • What is the blended cost of energy across solar, grid, and DG combined?
  • • How much grid dependency has solar actually displaced?
  • • Is a BESS justified — and what size?

A dedicated meter on every source — solar, grid, and DG — closes the gap. Titan provides bi-directional Class 0.5S measurement on all of them, with the same cloud dashboard rolling up the data into actionable comparisons.

Solar Power Monitoring System — What Titan Measures

Four data streams, one dashboard. A solar power monitoring system that also covers grid import/export and diesel generator output.

Solar Generation

kWh delivered to the building, peak generation, self-consumption ratio, daily and seasonal trends.

Grid Import & Export

Bi-directional metering for net metering compliance. Time-of-use registers for peak/off-peak tariffs.

Diesel Generator

Runtime hours, fuel cost (configurable), kWh delivered, and CO₂ emissions.

Building Load

Total consumption per phase, per circuit, per tenant — across the entire facility.

Renewable Comparison Engine

The platform's renewable comparison engine takes the per-source data from Titan and produces:

  • Source-wise kWh and cost — solar, grid, DG broken out month over month
  • Blended cost of energy — what you actually paid per kWh once all sources are factored in
  • Solar self-consumption % — how much PV generation stayed on-site
  • Grid dependency % — how much you still pull from the utility
  • DG runtime + fuel cost — diesel as a true line item
  • Source-mix charts — at-a-glance daily, monthly, and annual breakdowns

For BESS feasibility, the platform also runs load profile analysis, solar surplus windows, recommended capacity, and payback ROI with tariff sensitivity scenarios.

Use Cases

Five common scenarios from rooftop solar to multi-site portfolios.

Commercial Rooftop Solar

Verify EPC performance against PPA guarantees. Track solar self-consumption vs grid export over time. Monitor inverter health from the AC side.

Solar EPC Portfolios

Aggregate dashboards across multiple client sites. Defensible reporting on plant performance, with no dependence on a single inverter portal.

Industrial Facilities with DG Backup

Compare grid + solar + DG costs side by side. Identify when DG is being run uneconomically. Plan BESS to displace diesel.

Net Metering Compliance

Bi-directional metering with import and export registers, time-of-use tracking, and audit-ready exports for the utility.

Solar + BESS Sites

Track BESS charge/discharge cycles, calculate round-trip efficiency, and validate storage ROI against the original sizing assumptions.

Why Titan for Solar Monitoring

  • Bi-directional measurement — import and export on the same meter
  • Class 0.5S accuracy — utility-grade per IEC 62053-22
  • WiFi or Ethernet to the cloud — no inverter-vendor portal lock-in
  • CO₂ on-device — per-source emission factors for ESG reporting
  • Multi-source comparison in the Energy Intelligence Platform

Frequently Asked Questions

Six common questions about solar monitoring, self-consumption, and BESS sizing.

A DER (Distributed Energy Resource) monitoring system measures every on-site energy source — solar PV, battery storage, diesel generators — plus grid import/export, from a single dashboard. It answers questions that per-inverter portals cannot: how much solar is self-consumed, how much is exported, what the blended cost of energy actually is, and whether a BESS is justified. Titan is a DER monitoring system built on utility-grade Class 0.5S metering with bi-directional measurement on every source.
Inverters monitor themselves — DC input, AC output, error codes. They don't see grid import, they don't see DG runtime, and they don't measure self-consumption. Titan provides utility-grade Class 0.5S measurement on every source so the comparison is defensible.
Install one Titan meter on the solar circuit (measuring generation) and one on the grid circuit (measuring bi-directional import/export). The platform calculates self-consumption automatically as (Solar Generation − Grid Export) / Solar Generation × 100%.
Yes. Titan is bi-directional with separate import and export registers, supports time-of-use tariffs, and produces audit-ready exports for utility submissions.
Titan logs the actual load profile and solar generation profile over weeks or months. The Energy Intelligence Platform then runs sizing scenarios — battery capacity, payback, tariff sensitivity — using your real data instead of sales assumptions.
Yes. The platform supports portfolio-level views with drill-down to any individual site. Useful for solar EPCs managing client portfolios and large facility owners with multiple plants.
No. Titan is a metering and analytics layer — not a control system. It exports data to your SCADA or BMS via Modbus RTU/TCP if you want a unified operations view.
A behind-the-meter (BTM) solar monitoring system measures how a rooftop or captive solar plant interacts with the building or facility load — independent of the utility billing meter. It tells you, in real time, how much of your load is being met by solar versus how much is coming from the grid (and how much, if any, is being exported). It's the measurement layer that owners need to know whether their solar investment is performing.
A solar net meter is a utility billing meter installed by the DISCOM at the grid interconnection point — it's the meter the utility uses to calculate net energy import / export for billing. A behind-the-meter monitoring system is for the plant owner — it tracks generation, consumption, performance ratio, savings, and ESG metrics independently of the utility's billing process. We focus on the owner-facing monitoring side; we do not supply DISCOM net meters.
Net metering credits kWh, not kVA, and not time. Even under perfect 1:1 net metering, owners are still bleeding value in five specific ways the bill alone cannot reveal: (1) maximum demand penalties on kVA peaks during non-solar hours, (2) banking caps and forfeit when generation exceeds the state-allowed limit, (3) ToU / TOD tariff arbitrage if your retail tariff is time-differentiated, (4) plant under-performance hidden by net credits — soiling, inverter derating, string faults, (5) CBAM and ESG Scope 2 audits that demand kWh-level attribution. Behind-the-meter measurement is what surfaces all five.
Yes. The hardware-grade meters do the primary generation, consumption, and grid measurement — independent of the inverter. Inverter integration (Modbus / SunSpec) adds string-level health and fault visibility, and we support all major inverter brands (Sungrow, Huawei, SMA, Solis, Polycab, Waaree, ABB, Delta, etc).
Carbon savings (tCO2 avoided) calculated using grid emission factors, monthly and annual self-consumption summaries, and audit-grade M&V data exportable for GRI / SBTi / BRSR reporting. Methodology aligned with IPMVP and the GHG Protocol.
Yes — we work with EPCs as a channel partner for post-commissioning monitoring. EPCs can include the monitoring system in the BoQ, white-label the dashboard, or refer clients to Tech OVN directly. Talk to our team about EPC partner pricing.
