Ensight Solar calculates key performance indicators (KPIs) and detailed breakdowns of system losses to proactively and automatically inform asset managers, operations and maintenance (O&M) teams, and insurance underwriters regarding the as-built performance of photovoltaic plants. Our algorithms translate system underperformance and component health issues into prioritized corrective actions that help increase revenue, organize and schedule O&M more efficiently and cost-effectively, and generally support the long term performance and health of PV assets.

Ensight Solar provides an indispensable set of powerful analytic tools that automatically break down system losses into 15 categories, providing an unprecedented level of insight into the impact of those losses. This insight is made all the more meaningful by way of detailed corrective actions that Ensight Solar automatically recommends. Because the actual costs of taking action can be accounted for within the solution, Ensight Solar recommends only those corrective actions that make economic sense.

Based on analysis of the system losses, Ensight Solar generates corrective action recommendations that incorporate information about the cost of taking action to only suggest actions that make economic sense.

  • wind stowing of trackers
  • tracker errors, including stow outside of wind events
  • snow losses
  • soiling, including zone-level assessment of different parts of each plant
  • shading, accounting for obstructions, vegetation, and intra-array shade
  • module thermal losses
  • down strings
  • underperforming strings
  • inverter efficiency, relative to manufacturer specifications
  • inverter clipping
  • energy loss due to VAR support
  • nighttime losses

Data Quality and Sensor Integrity are Critical

Our advanced analytics engine automatically detects and corrects for missing or invalid data to ensure that key performance indicators and loss breakdown analysis results are accurate. Ensight Solar detects sensor outliers automatically and creates alerts with recommended corrective actions before removing unreliable sensor data from the assessment.

We Review your Primary Sensors

Weather sensor inspection is often overlooked, and sensors that are out of calibration or proper alignment cause inaccurate and misleading plant performance assessments. Ensight Solar detects sensor outliers automatically and creates alerts with recommended corrective actions before removing unreliable sensor data from the assessment.

Downtime Root Cause Analysis

Inverter-by-inverter analysis provides rapid insight into the underlying causes of system losses. The downtime analysis algorithm compiles the series of continuous inverter down times as individual downtime events, for each inverter. Downtime events are also broken down into categories depending on whether they were caused by snowfall, grid curtailment, or other causes.

Shading & Soiling Characterization

Our proprietary shade detection algorithm creates a dynamic model of expected production on an inverter-by-inverter basis to reveal real-life shading. Even vegetation growth can be detected and acted upon sensibly.

Corrective Action Recommendations

With Ensight Solar, you can detect and resolve plant performance anomalies that are indicative of potential future equipment problems. Ensight incorporates the cost of action, whether it is washing modules or fixing down strings, so that operational performance can be maximized within budgeting constraints.
