🔌 What is an On-Grid Solar System?
An on-grid solar system, also known as a grid-tied system, is connected directly to the public electricity grid.
How it works:
- Solar panels generate electricity during the day.
- Your home or business uses this energy first.
- If your solar panels produce more electricity than needed, the excess goes to the grid.
- If you need more power than your panels generate, electricity is pulled from the grid.
✅ Benefits of On-Grid Systems:
- Lower Electricity Bills: You only pay for the power you use from the grid.
- Net Metering Support: In the UAE, net metering programs by DEWA and ADDC allow you to earn credits for sending excess solar power back to the grid.
- No Need for Batteries: You don’t need battery storage, which reduces system cost.
- Easy Maintenance: Fewer components make it simple and affordable to maintain.
“On-grid systems are like teamwork — you generate energy, the grid supports you, and together you save.”
🔋 What is an Off-Grid Solar System?
An off-grid solar system is completely independent from the public power grid. It stores energy in batteries for use when the sun isn’t shining.
How it works:
- Solar panels charge batteries during the day.
- You use stored energy at night or during cloudy days.
- There’s no backup from the grid, so your system must generate and store enough energy to meet your full power needs.
✅ Benefits of Off-Grid Systems:
- Full Energy Independence: Ideal for remote areas without grid access.
- No Electricity Bills: You generate and consume your own power.
- Reliable in Power Outages: You won’t be affected by grid failures.
- Sustainable Living: Encourages mindful energy use and zero reliance on fossil fuels.
“Off-grid living is not just about saving money. It’s about total freedom and control over your energy.”

Why It Matters in the UAE
The UAE is blessed with abundant sunshine and supportive government policies for solar adoption.
- On-grid systems are perfect for cities like Dubai, Abu Dhabi, and Sharjah where grid access is reliable.
- Off-grid systems are great for farms, construction sites, or remote villas with limited or no grid access.
With programs like Shams Dubai (DEWA) and Abu Dhabi’s net metering, switching to solar — especially on-grid — has never been more attractive.
