Zero Export Pv System

Introduction

A zero export PV system is a solar photovoltaic (PV) system designed to ensure that any electricity generated by the solar panels is consumed on-site and not fed back into the utility grid. Essentially, it prevents the export of excess solar energy to the grid.

  • On-site Consumption: The primary goal is to maximize the use of solar energy for the homeowner’s or building’s own electricity needs.
  • No Export to the Grid: Zero export systems are engineered to avoid sending any surplus solar power into the public power grid.
  • Grid Stability and Regulations: This approach is often implemented when local grid operators restrict or prohibit the export of solar energy due to concerns about grid stability or to comply with specific regulations.
  • Dynamic Power Regulation: Zero export systems dynamically adjust the solar inverter’s power output to match the building’s electricity consumption in real-time, ensuring no excess power is generated.
  • Alternatives to Export: Instead of exporting excess energy, zero export systems may utilize battery storage to store the surplus for later use, or simply reduce solar production to match on-site consumption.

My PV System

I started with a 600 Watt Microinverter and two 380 Watt Solarpananels, I then built a receiver with a ESP32 microcontroller and a 2.4Ghz transceiver to receive status information from the microinverter which sends out serial data over 2.4Ghz when triggered. more info here
