How to choose a solar installation company in the UAE
Most solar problems in the UAE are decided before anything reaches the roof: by who you hire and what their quotation includes. These are the checks that matter in every emirate, with a checklist for comparing quotes.
- First check
- Enrolment with your utility
- Second check
- Equipment on the approved list
- Then compare
- Scope, warranties, O&M
- Applies to
- Villas and commercial sites
Disclosure. Smart Gulf Energy is a solar installation company, so we have an interest in this topic. The checks below are the ones we would want a client to apply to us as well as to anyone else.
1. Start with utility enrolment, emirate by emirate
A grid-connected system has to be approved, inspected and metered by the utility that supplies your site, and each utility decides which contractors may submit that work. There is no single national approval, so the first question is whether the company is enrolled with your utility.
| Where the site is | Utility | What to check |
|---|---|---|
| Dubai | DEWA | The company appears on DEWA's published list of enrolled Shams Dubai contractors and consultants, in a category that covers your system size |
| Abu Dhabi, Al Ain, Al Dhafra | ADDC or AADC | Which of the two utilities holds your site, and that the contractor is enrolled with that one |
| Sharjah city and main urban areas | SEWA | Enrolment with SEWA, and that the site is not in an EtihadWE enclave |
| Ajman, Ras Al Khaimah, Fujairah, Umm Al Quwain | EtihadWE | Enrolment with EtihadWE for its Distributed Solar System programme |
Enrolment does not transfer between utilities. A DEWA-enrolled contractor is not automatically allowed to submit to ADDC, SEWA or EtihadWE, so a company that works well in Dubai may not be able to connect your system in Ras Al Khaimah. Confirm enrolment with the utility itself rather than relying on a logo on a website. In Dubai you can check DEWA's register; our Shams Dubai guide links to it and explains the contractor categories.
Sharjah needs one extra step. Some northern and eastern enclaves fall under EtihadWE rather than SEWA, and the process and credit rules change across that line. The UAE solar rules comparison sets out all five utilities in one table.
2. Check the equipment against the approved list
Each utility only connects equipment that appears on its approved list. In Dubai that means DEWA's list through the DRRG Equipment Portal, with ECAS certification through MoIAT. A quotation built around unlisted modules or inverters describes a system that cannot legally be connected, however good the price looks.
Ask every company for the exact make and model of the modules and inverter, plus datasheets, and check them against the list yourself. If a model becomes unavailable, any substitute should also be listed and agreed with you.
3. Understand the three warranties
A solar system usually carries three separate warranties, and quotations often blur them together.
- Module warranty from the panel manufacturer, normally split into a product warranty against defects and a performance warranty on output over time. Ask for both terms in writing.
- Inverter warranty from the inverter manufacturer. It is usually shorter than the module warranty, so ask how long it is and whether an extension is offered.
- Workmanship warranty from the installer, covering mounting, cabling, roof penetrations and waterproofing. This is the one that depends entirely on the company you hire still being around.
Also ask who handles a claim, and whether labour is covered or only the replacement part. A manufacturer warranty is only useful if someone local will diagnose the fault and swap the part.
4. Ask what happens after handover
Dust settles on panels quickly in the UAE and measurably reduces output between cleans, so operation and maintenance is part of the return, not an optional extra. Ask what each company's O&M offer includes: cleaning frequency, monitoring and who watches it, fault response time, and the annual cost.
5. Quotation red flags
- No model numbers. You cannot check equipment against the approved list.
- Hardware-only pricing. Design approval, inspection and the utility's connection fee are left out, so the real cost appears later. In Dubai, DEWA estimates the connection fee at design approval stage and a complete quotation includes it.
- Sizing from roof area alone. A proper design starts from your bills and your emirate's credit rules.
- Identical sizing logic in every emirate. DEWA and SEWA credits carry forward, EtihadWE credits expire within the calendar year, and Abu Dhabi runs self-supply. One approach cannot fit all four.
- A price far below the others with none of the above explained. Our solar cost guide explains the six drivers behind a price so you can see where the gap comes from.
6. Questions to ask every company
- Are you enrolled with the utility that covers my site, and in which category?
- Which exact module and inverter models are you quoting, and are both on that utility's approved list?
- Does the price include design, approvals, inspection, connection and metering, or only the hardware and installation?
- What are the module, inverter and workmanship warranty terms, and who handles a claim?
- What does your O&M plan include, and what does it cost after the first year?
- How long from contract to generation?

Frequently asked questions
How do I know if a solar installation company is approved in the UAE?
Check enrolment with the utility that supplies your site: DEWA in Dubai, ADDC or AADC in Abu Dhabi, SEWA in Sharjah city, or EtihadWE in the Northern Emirates. In Dubai, DEWA publishes its list of enrolled Shams Dubai contractors and consultants. Confirm the company's category covers your system size.
Can one solar company install in every emirate?
Only if it is enrolled with each relevant utility. Enrolment is utility-specific, so a DEWA-enrolled contractor is not automatically permitted to submit applications to ADDC, AADC, SEWA or EtihadWE.
What warranties should a solar installation include?
Three: the module manufacturer's product and performance warranty, the inverter manufacturer's warranty, and the installer's workmanship warranty covering mounting, cabling and roof waterproofing. Ask for each term in writing and who handles a claim.
Why is one solar quotation much cheaper than the others?
Usually because of equipment that is not on the utility's approved list, a scope that leaves out approvals, inspection and connection, or no maintenance provision.
Do I need a maintenance contract after installation?
It is strongly advisable. Dust reduces output between cleans in UAE conditions, so cleaning and monitoring protect the return.
