Expert Solar Power Quality Analysis

Who We Are

We Shadow Energy, help solar plant, EPC companies, and industrial facilities identify power quality issues, improve system performance, and protect valuable electrical assets. Our expert-led testing and auditing solutions are designed to enhance energy efficiency, minimize losses, and ensure long-term operational stability.

Whether you operate a rooftop solar plant, ground-mounted solar farm, or captive solar installation, our comprehensive audits provide the clarity and technical insight needed to maximize return on investment and meet regulatory requirements.

Reliable solar power generation is not only about installing panels and inverters. It is also about ensuring that the electricity produced is clean, stable, efficient, and compliant with grid standards. That is where solar power quality analysis services.

What Is Solar Power Quality Analysis?

Solar power quality analysis is the process of measuring, monitoring, and evaluating the electrical characteristics of power generated by solar plants. It focuses on identifying disturbances that can affect system performance, equipment lifespan, and grid compatibility.

These disturbances may include:

• Harmonics

• Voltage fluctuations

• Frequency deviations

• Flicker

• Power factor problems

• Unbalanced loads

Using advanced power quality monitoring for solar plants, engineers assess how solar inverters, transformers, cables, and protection systems behave under real operating conditions.

The result is a detailed technical report that highlights existing issues, potential risks, and corrective actions required to maintain a healthy electrical network.

Why Power Quality Matters for Solar Power Plants?

Poor power quality can quietly damage your solar investment. Many plant owners discover issues only after inverter failures, frequent tripping, or penalties from utilities.

Here’s why power quality is critical:

• Protects inverters, transformers, and switchgear

• Prevents overheating and premature equipment failure

• Reduces downtime and maintenance costs

• Improves energy yield and system efficiency

• Ensures compliance with grid codes

• Maintains stable voltage and frequency

Without proper power quality testing services, hidden electrical issues can gradually reduce plant performance and profitability.

A professional solar plant electrical audit helps you stay ahead of these risks.

Our Scope of Work Under Solar PQA-

We provide end-to-end diagnostic, testing, and consulting services for solar power plants of all sizes.

Harmonic Analysis

Solar inverters are major sources of harmonics. Excess harmonics can cause:

• Overheating of transformers

• False tripping of protection devices

• Reduced inverter efficiency

Our solar inverter harmonic analysis identifies:

• Total Harmonic Distortion (THD)

• Individual harmonic orders

• Source of distortion

• Compliance with IEEE and IEC standards

We also recommend filters or mitigation techniques where required.

Voltage & Current Distortion

Voltage and current distortion affects system stability and component life.

We analyze:

• Voltage unbalance

• Sags, swells, and interruptions

• Load imbalance

• Neutral current issues

Accurate power quality analyzer testing allows us to capture real-time waveforms and trends.

Flicker Analysis

Flicker causes visible light fluctuations and indicates unstable voltage.

Our testing evaluates:

• Short-term and long-term flicker

• Impact on sensitive equipment

• Root cause identification

Power Factor Analysis

Low power factor leads to higher losses and utility penalties.

We assess:

• Displacement power factor

• True power factor

• Reactive power flow

• Capacitor bank health

Inverter Performance Testing

Inverters are the heart of a solar plant.

Our testing covers:

• Efficiency verification

• MPPT performance

• Temperature behavior

• Protection coordination

• Communication and monitoring accuracy

This forms a key part of our solar plant performance analysis.

Grid Compliance Testing

Utilities impose strict grid code requirements.

Our grid compliance audit for solar power plant checks:

• Harmonics limits

• Power factor compliance

• Voltage and frequency ride-through

• Anti-islanding behavior

We ensure your plant meets local DISCOM and national grid standards.

Energy Loss Identification

Energy losses reduce revenue silently.

We analyze:

• Cable losses

• Transformer losses

• Inverter losses

• Reactive power losses

Corrective measures are proposed to recover lost generation.
