In the UAE’s extreme heat and high electricity demand, many residents and businesses still rely on diesel generators. However, with rising diesel prices (AED 4.69/liter in 2026) and huge advances in solar technology, solar power has become the smarter, cleaner, and more economical choice for most users.
At Watts & Ergon, , a DEWA-approved solar company in Dubai, we help customers make the best decision between solar, generators, or hybrid systems.

| Cost per kWh | AED 0.10 – 0.20 (after payback) | AED 1.50 – 2.20 (fuel + maintenance) | Solar |
