What is a Grid Connected PV System?

A grid connected photovoltaic system is a solar power setup that generates electricity from sunlight and delivers it directly to the electrical grid or to on-site loads. Unlike standalone (off-grid) systems, grid-connected PV systems do not require battery storage, as the grid itself serves as a virtual battery.

According to a Grid Connected PV Systems Market report, the industry is expected to grow significantly in the coming years.

Key Components

  1. Solar Panels (PV Modules):

    • Convert sunlight into direct current (DC) electricity.

    • Composed of many solar cells, typically made from silicon.

  2. Inverter (String or Microinverter):

    • Converts DC electricity into alternating current (AC), which is compatible with the grid and household appliances.

    • String inverters handle several panels at once, while microinverters are attached to individual panels.

  3. Metering System:

    • Net metering allows excess electricity to be fed back into the grid.

    • Measures both the electricity consumed and the electricity exported.

  4. Electrical Panel (Distribution Board):

    • Manages power distribution between the solar system, the home or building, and the utility grid.

  5. Utility Grid:

    • Provides electricity when the solar system doesn’t produce enough (e.g., at night or during cloudy weather).

    • Receives excess energy during peak solar production.

How the System Works (Step-by-Step)

  1. Solar Energy Collection:

    • Solar panels absorb sunlight and generate DC electricity.

  2. Conversion to AC Power:

    • The inverter converts DC to AC, making it usable for appliances and suitable for grid integration.

  3. Power Usage and Distribution:

    • Electricity flows to on-site loads first.

    • Any excess electricity is exported to the grid.

  4. Net Metering and Compensation:

    • A bi-directional meter tracks both consumed and exported electricity.

    • Users receive credits for the electricity sent to the grid, offsetting their electric bills.

Advantages of Grid-Connected PV Systems

  • ⚡ Cost Savings: Reduces or eliminates electricity bills via net metering.

  • 🌱 Environmentally Friendly: Reduces carbon footprint and greenhouse gas emissions.

  • 🔋 No Need for Batteries: The grid provides backup, reducing upfront costs.

  • 🔄 High Efficiency: Power is used immediately or exported with minimal energy loss.
