How Does an On-Grid Solar System Work? | Deep Tec Sri Lanka

How Does an On-Grid Solar System Actually Work?

Introduction

With rising energy costs, power cuts, and climate pressures, Sri Lankans are turning to solar powerΒ  especially on-grid solar systemsΒ  to secure reliable, affordable, and clean energy.

At Deep Tec, we specialize in designing and installing world-class on-grid systems using premium brands like AE Solar and Jinko Solar.

πŸ’‘ What Is an On-Grid Solar System?

An on-grid system (also called grid-tied) connects your home or business to Sri Lanka’s national grid, managed by the Ceylon Electricity Board (CEB).

  • βœ… Use solar power directly when available
  • βœ… Send excess energy back to the grid via net metering
  • βœ… Pull power from the grid at night or on cloudy days

This lets you enjoy big savings without needing expensive batteries.

⚑ Step by Step: How Power Comes from the Grid

To understand how solar connects, let’s break down the grid:

1️⃣ Electricity Generation

Large power plants generate electricity (hydro, coal, wind, or solar).

2️⃣ High Voltage Transmission

Electricity is sent across the country via transmission lines.

3️⃣ Step Down Distribution

Transformers reduce voltage for safe use in homes and businesses.

4️⃣ Final Supply

Electricity arrives at your meter and powers your appliances.

πŸ”Œ How On-Grid Solar System Works

Understanding how on-grid system works is essential when deciding to invest in solar.

On-grid solar system connection
  • βœ… Solar Panels (like those from AE Solar or Jinko Solar) capture sunlight and generate DC electricity.
  • βœ… Solar Inverter converts DC into AC electricity for your home.
  • βœ… Net Meter tracks how much electricity you use vs. how much you export to the grid.
  • βœ… Grid Backup ensures you always have power, even when the sun isn’t shining.
