Photovoltaic Monitor

Photovoltaic Monitor Turns Your Phone into a Professional Solar Panel Diagnostic Tool

No more guessing if your solar array is underperforming. This utility app gives you a direct, real-time look at your photovoltaic system’s electrical output, temperature, and efficiency metrics—without needing a separate datalogger or expensive handheld meter. Built for system owners, installers, and field technicians, it consolidates live sensor data into a single, scannable dashboard.

Core Diagnostic Capabilities

The app connects to your inverter or charge controller via local Wi-Fi or Bluetooth and pulls raw performance data every 60 seconds. You can view instantaneous voltage, current, and power (in watts) for each connected panel string. A built-in temperature overlay shows module surface heat, helping you spot thermal runaway or shading issues before they cause permanent damage. The historical log graphs power output over the last 7 days, with hourly and daily aggregates.

• Live Power Curve – Track wattage output per panel string with 1-second refresh rate.
• Temperature Mapping – Overlay module surface heat readings onto your array layout.
• Fault Code Decoder – Translate inverter error codes into plain English troubleshooting steps.
• Energy Yield Calculator – Estimate daily kWh based on current irradiance and panel angle.
• Comparative Baseline – Compare today’s production against the same day last week.

Key Advantages for Daily Use

The interface is designed for one-handed operation in the field. All critical metrics are color-coded: green for normal range, yellow for marginal, red for alert. You can set custom thresholds for voltage, current, and temperature; when a parameter exceeds the limit, the app triggers a push notification and logs the event with a timestamp. No internet connection is required for core diagnostics—the app works offline with local network hardware. Data can be exported as a CSV file for integration with spreadsheets or maintenance reports.

Disclaimer: This app requires a compatible inverter or charge controller with Wi-Fi or Bluetooth connectivity. A stable local network is needed for data transmission. Certain advanced features, such as cloud backup and multi-array aggregation, require an optional in-app purchase. Performance depends on sensor accuracy and hardware specifications. Internet connection is required for push notifications and software updates.
