What is DEWA's Hab-Reeh platform?

Hab-Reeh is DEWA's smart platform for self-assessment of photovoltaic system designs under the Shams Dubai initiative. Consultants and contractors use it to check harmonic emissions and power quality compliance before submitting a design for approval.

Do I need to use Hab-Reeh myself as a building owner?

No. Hab-Reeh is a tool for DEWA-enrolled consultants and contractors, not for property owners. The owner's job is to check that the company they hire appears on DEWA's enrolled Solar PV Contractors and Consultants list.

Which inverters can be used under Shams Dubai?

Only models on DEWA's approved equipment list. As of August 2026 that list contains approximately 180 approved inverter models, and Hab-Reeh builds design options from combinations of those models.

Hab-Reeh: DEWA solar design approvals hit 100% compliance

Q: How long does DEWA solar approval take in Dubai?

DEWA has not published a fixed number of days. What it has published is the direction: Hab-Reeh reduced assessment times and lifted compliance of submitted designs with power quality standards to 100%, and the platform is now integrated with the Getting Solar Permits and Connection service so both steps run as one process.

Hab-Reeh: DEWA solar design approvals hit 100% compliance

DEWA solar approval in Dubai runs through Hab-Reeh: usage up 17% in H1 2026, design compliance with power quality standards now 100%. What it changes.

DEWA solar approval in Dubai now runs through a single digital gate. DEWA said on 4 August 2026 that usage of its Hab-Reeh self-assessment platform grew 17% in the first half of 2026 versus the same period of 2025, and that compliance of submitted designs with power quality standards reached 100%. For a villa or warehouse owner, that means fewer rejected drawings and a shorter path from quote to meter.

What is Hab-Reeh, and what does it actually check?

Hab-Reeh is DEWA's smart platform for self-assessment of PV system designs under the Shams Dubai programme. Its specific job is harmonic assessment. Abdulla Al Aghbari, Acting Executive Vice President of Power and Water Planning at DEWA, said the platform lets consultants and contractors verify compliance with power quality standards before submitting designs for approval, and that it is particularly effective at assessing harmonic emissions — the electrical distortion that inverters can inject at customer premises and that degrades network power quality.

This is not a formality. Harmonics are the single most common technical reason a rooftop design gets sent back. Checking them before submission, rather than after a DEWA reviewer finds them, is the whole point of the tool.

Why the approval step got faster in 2026

DEWA has integrated Hab-Reeh with its Getting Solar Permits and Connection service. Consultants and contractors now complete the harmonic self-assessment and submit the design approval through a single process rather than two. DEWA states the integration is designed to reduce time, effort and cost.

The platform also offers unlimited design options built from combinations of solar inverters selected from DEWA's list of approximately 180 approved models. In practice that means a contractor can test several inverter configurations against the power quality rules before committing to one — useful on commercial and industrial roofs where string layouts are rarely simple.

How big is Shams Dubai now?

Shams Dubai had connected more than 725 MW of rooftop PV across 8,430 buildings to DEWA's distribution grid as of June 2025. In 2024 the programme handled more than 1,700 solar connection requests, a 30% year-on-year increase, and 111 certified companies were authorised to design and install under the framework. DEWA has not published an updated capacity figure alongside the August 2026 Hab-Reeh announcement, so treat 725 MW as the last confirmed number rather than the current one.

What this changes for a building owner

Three practical consequences.

Ask which enrolled company is signing the design. Hab-Reeh is a contractor tool, not an owner tool. Your leverage is upstream: confirm the company appears on DEWA's enrolled solar PV contractors and consultants list before you sign anything.
Ask which inverter model is quoted, by name. If the model is not on DEWA's eligible equipment list, the design cannot pass Hab-Reeh and the project stalls at approval. A quote that names only "5 kW inverter" is not a quote.
Do not read faster approvals as a reason to skip diligence. The regulatory bottleneck is shrinking; the engineering one is not. Sizing against your actual DEWA tariff slabs still determines whether the system pays back, and no platform checks that for you.

Where this sits in DEWA's wider digital push

Saeed Mohammed Al Tayer, MD and CEO of DEWA, framed Hab-Reeh as part of an investment programme in technologies that streamline the work of contractors, consultants and strategic partners and support the net-zero transition. DEWA also notes that Hab-Reeh received a seven-star rating at the International Best Practice Competition. The direction of travel is consistent: Dubai is removing paperwork friction from rooftop solar rather than changing its economics — the process gets shorter, the tariff maths stays the same.
