GRD Solar Panel Efficiency Monitoring System

GRD Solar Panel Efficiency Monitoring System

Quick Overview

The GRD Solar Panel Efficiency Monitoring System measures solar radiation, solar power output ( Dc voltage and current or water temperature ), and current weather data such as air temperature, wind speed etc. and delivers the data wirelessly using GPRS to a secure web page.

Details

The GRD Solar Panel Efficiency Monitor provides a cost effective way to monitor solar panel performance on remote sites. It measures the electrical outputs from PV panels, or water temperature from solar collectors, along with incoming solar radiation, and air temperature. It can be integrated with your existing metering, or supplied as a complete system with voltage and current sensors and a full range of environmental sensors for solar radiation and weather.

  • Stand alone system with integral GPRS/GSM modem
  • Automatically emails hourly, daily or weekly reports
  • Publishes data direct to a web page
  • Web interface SMS text messages and / or emails on alarm
  • Remote configuration via browser interface
  • 6 Analogue inputs
  • 14 Digital State Inputs
  • 2 Counter Inputs
  • 2 Relay Outputs (5A at 24vDC)
  • Expand to 32 additional analogue/digital channels
