What Shams Dubai actually is
Shams Dubai is DEWA's distributed solar programme, launched in 2015. It lets any DEWA customer — villa, commercial building or industrial facility — install rooftop solar, connect it to the grid and offset their bill through net metering. More than 725 MW is now connected across over 8,400 buildings in Dubai.
Two rules define the programme. First, only DEWA-enrolled contractors and consultants may design, submit and install systems — this is not optional, and an installation by anyone else cannot be legally connected. Second, every module and inverter must appear on DEWA's approved equipment list and carry Emirates Conformity Assessment Scheme certification.
The four stages, honestly described
| Stage | What happens | Where delays actually occur |
|---|---|---|
| 1. NOC | Contractor submits the solar NOC application via Hab Reeh; DEWA issues a No Objection Certificate | Ownership documentation and premises number mismatches |
| 2. Design approval | Site plans, system design and equipment details submitted; connection fee estimated on approval | Equipment not on the approved list; undersized protection; poor single line diagrams |
| 3. Installation & inspection | Enrolled contractor installs; DEWA inspects and installs the bidirectional meter | Deviations from the approved design found at inspection |
| 4. Generation | System generates; exports are credited on the DEWA bill | — |
A villa system typically moves from signed contract to generation in about two weeks. Commercial systems take longer, driven mostly by design approval complexity rather than construction time.
How the net metering actually works
Every kilowatt-hour your system exports is credited against kilowatt-hours you import. Credits that are not used in a billing period roll over to the following period. This carry-forward is the detail that matters most for system sizing: unlike the Northern Emirates scheme, where credits expire within the calendar year, Dubai lets summer overproduction offset later consumption. That is why an identical building justifies a larger array in Dubai than in Ras Al Khaimah.
The sizing rule most people miss. Capacity is limited relative to your connected load — as a programme rule, installed capacity cannot exceed your applicable share of total connected load, with systems up to roughly 2 MW per plot possible for large premises. Sizing to your actual consumption profile, not your roof area, is what an honest design looks like.
Equipment rules
DEWA maintains an approved equipment list through its DRRG Equipment Portal, and equipment must additionally carry ECAS certification through MoIAT. In practice this means a quotation built around unlisted equipment is a quotation for a system that cannot be connected — checking the list is the first thing to do with any proposal you receive.
Documents you will usually need
Your contractor confirms the exact list at NOC stage, but applications typically draw on the following:
- The DEWA account and premises number for the building
- Proof of ownership, or the owner's written consent where the applicant is not the owner
- Recent electricity bills, used to size the system to real consumption
- Roof or site drawings, used for the layout and structural check
The Shams Dubai calculator
DEWA publishes an official Shams Dubai Calculator that estimates solar potential from a drawn roof area. It is a good first look. Because it does not know your consumption profile or connected load, a proper design still starts from your bills. Our UAE solar calculator sizes a system against your emirate's actual credit rules.
Is Shams Dubai worth it?
For most owner-occupied buildings with steady daytime or year-round consumption, it usually is, but the answer depends on three things: how much electricity you use, how much usable roof you have, and the installed cost. Credit carry-forward helps, because summer generation is not wasted. What drives the price is covered in our guide to solar panel cost in Dubai.
Shams Dubai is not Shams Free Zone
People searching for "Shams" often find two unrelated things. Shams Dubai is DEWA's distributed solar programme covered on this page. Shams Free Zone is the Sharjah Media City free zone for company setup and licensing. They share a name and nothing else.
Choosing a contractor
Three checks take five minutes and remove most of the risk: verify the company appears on DEWA's enrolled contractors list; confirm the contractor category (A, B or C) covers your system size; and ask for the equipment datasheets so you can confirm listing yourself. A contractor who hesitates on any of the three is telling you something.
Smart Gulf Energy has been an enrolled contractor delivering solar in Dubai since 2005 — before Shams Dubai existed — and handles every stage above, from NOC to meter, as standard scope.

Frequently asked questions
Who can apply for Shams Dubai?
Any DEWA customer — residential villas, commercial buildings and industrial facilities — with a suitable roof or space. Applications must be submitted by a DEWA-enrolled contractor or consultant.
How long does Shams Dubai approval take?
A villa system typically moves from contract to generation in about two weeks across the NOC, design approval, installation and inspection stages. Commercial systems take longer, mainly in design approval.
Do Shams Dubai credits expire?
No. Exported units are credited against consumption and unused credits roll over to following billing periods, which is why Dubai systems can be sized more generously than in emirates where credits expire annually.
Can I use any solar panels in Dubai?
No. Equipment must appear on DEWA's approved equipment list via the DRRG Equipment Portal and carry ECAS certification. Systems built with unlisted equipment cannot be connected.
Can tenants apply for Shams Dubai?
The application relates to the premises and requires the owner's involvement. Tenants should approach it jointly with their landlord.
What does the DEWA inspection check?
That the installed system matches the approved design — equipment, protection, earthing and labelling. Deviations found at inspection are the most common cause of late-stage delay.
Is there an official Shams Dubai calculator?
Yes. DEWA publishes a Shams Dubai Calculator on its website that estimates solar potential from your roof area. A contractor then sizes the actual system from your consumption and connected load.
Is Shams Dubai the same as Shams Free Zone?
No. Shams Dubai is DEWA's distributed solar programme. Shams Free Zone is the Sharjah Media City free zone for business setup. They are unrelated.
