Dubai residents face some of the highest summer electricity bills due to intense air-conditioning usage. Many villa owners receive DEWA bills between AED 1,500 and AED 4,000+ per month during peak summer. Solar power has become the most effective solution to dramatically cut these costs.
At Watts & Ergon, we specialize in DEWA-approved solar installations that deliver real, measurable savings under the Shams Dubai net metering program. This comprehensive guide reveals exactly how much you can save in 2026.
Key Takeaway: Most homeowners in Dubai can reduce their DEWA bills by 60% to 90%+ with a properly sized solar system.
| Monthly Consumption (kWh) | Rate (AED per kWh) |
|---|---|
| 0 – 2,000 | 0.230 |
| 2,001 – 4,000 | 0.280 |
| 4,001 – 6,000 | 0.320 |
| 6,001 and above | 0.380 |
Your solar panels power your home first. Excess energy is exported to the DEWA grid and credited at full retail rates. Credits roll over, significantly reducing or eliminating your monthly bills.
