sun2X Energy Team
Renewable Energy Specialists — UAE & GCC
The sun2X team combines decades of C-level experience in high-voltage battery systems, electric drivetrains, solar energy and grid infrastructure across European and international markets, now applied to the UAE renewable energy landscape. All technical content on this site is based on direct project experience with DEWA, ADDC and UAE authority approvals.
Quick Answer: Our 3-Phase Approach
What is sun2X's 3-phase approach to renewable energy projects?
Phase 1 — Business Case & Planning: Feasibility study, site survey, DEWA grid check and 25-year financial model (9 weeks) — fee credited toward your project. Phase 2 — Approvals & Execution: DEWA approval, engineering, procurement and installation (38 weeks). Phase 3 — Handover & Operations: Commissioning, energisation and 25-year O&M contract. One contract, one contractor, one performance guarantee.
Why a Structured Approach Matters in the UAE
Renewable energy projects in the UAE are technically, commercially and regulatorily more complex than in most markets. DEWA approval timelines, UAE summer installation restrictions, LFP battery thermal management requirements and EV tariff compliance under Cabinet Resolution No. 81 all demand careful sequencing. A project that skips the feasibility phase risks discovering grid capacity limitations after equipment is ordered. A project that skips proper commissioning risks losing the DEWA NOC and operating without net metering credits.
sun2X's 3-phase, 6-step approach was built specifically for UAE project conditions — not adapted from European methodologies. Each phase has defined entry criteria, specific deliverables and a clear handoff to the next phase. The result is predictable timelines, bankable business cases and systems that perform as modelled over their 25-year lifetime.

Phase One
Business Case & Planning
Foundation for every decision that follows
Phase 1 is the most important phase — and the one most often skipped by inexperienced developers. Before any capital is committed, sun2X delivers a complete, bankable planning report that answers three questions: Is this project technically feasible at this site? Is it financially attractive for this client? And what is the optimal system configuration to maximise return?
The Phase 1 deliverable is the foundation for board approval, EDB financing applications and long-term project structuring. It is also the document that protects the client from the most common and expensive mistake in UAE renewable energy: ordering equipment before confirming DEWA grid capacity.
Step 01 — 9 Weeks
Feasibility & Business Case
The feasibility study is sun2X's most comprehensive planning deliverable. It combines physical site assessment with financial modelling to produce a document that clients can take directly to their board or to the Emirates Development Bank.
Site Assessment
- ●Structural roof survey and load capacity
- ●Drone shading and irradiance analysis
- ●DEWA/ADDC existing LOC and headroom
- ●EV parking audit and cable routing
- ●HVAC load profile and peak demand window
Financial Modelling
- ●12-month electricity consumption analysis
- ●Solar yield simulation (PVSyst)
- ●Battery dispatch and peak-shaving model
- ●EV charging revenue projection
- ●25-year NPV, IRR and simple payback
sun2X offers the Phase 1 feasibility study as a paid service, delivered within 2 weeks of site visit. The fee is fully credited toward your project if you proceed to Phase 2 — no obligation to continue. This is the starting point for every project — request yours here.
Phase Two
Approvals & Execution
From approved business case to energised system
Phase 2 is the longest and most complex phase — covering four of the six steps and spanning approximately 38 weeks. It begins the moment the client approves the business case and sun2X submits the grid study to DEWA. It ends with a commissioned, energised, DEWA-approved system ready for handover.
Step 02 — 10 Weeks
DEWA/ADDC Approval & Letter of Credit
The Letter of Credit (LOC) from DEWA, ADDC or SEWA confirms the available grid capacity and connection terms for the project. Without the LOC, no equipment can be specified or ordered — because the LOC defines the allowable system size, protection relay requirements and meter type.
Grid Study Submission
Load-flow and fault-level analysis submitted to the relevant utility. Documents the site's existing consumption, proposed new loads (solar, battery, EV) and grid impact.
Protection Design Review
UAE mandates IEC 61727-compliant interface protection with auto-disconnect on grid fault. For systems above 200 kW, a full protection co-ordination study is required.
Authority NOC — DM / Trakhees / Tanweer
Dubai Municipality (mainland), Trakhees (JAFZA), Tanweer (Abu Dhabi). The full permit pack involves 18–24 documents. sun2X tracks all submissions and re-submissions.
Step 03 — 10 Weeks
Engineering & Procurement
Once the LOC is issued, detailed engineering drawings are prepared and equipment is ordered. sun2X specifies only components validated for UAE desert conditions — this is where the Tier-1 automotive industry background matters most.
Engineering Deliverables
- ●Single-line electrical diagrams
- ●Structural mounting drawings
- ●Cable routing and sizing calculations
- ●Battery thermal management design
- ●EV load management system design
UAE Equipment Standards
- ●Bifacial TOPCon modules, −0.30%/°C
- ●LFP batteries with active liquid cooling
- ●IP66 enclosures for outdoor installations
- ●IEC 60947-2 switchgear rated at +55°C
- ●OCPP 2.0.1 EV chargers, IP55
Step 04 — 12 Weeks
Installation — The UAE Summer Plan
Installation is the most visible phase — and the one most affected by UAE-specific conditions. UAE Labour Law restricts outdoor work between 12:30 and 15:00 from June to September. For large rooftop and cabling projects, night-shift installation is therefore mandatory during summer, adding approximately 15% to labour cost but allowing year-round project delivery.
UAE Summer Installation Protocol
- ●All equipment staged in climate-controlled warehousing (never outdoors for >24h)
- ●Rooftop work: 05:00–12:00 and 16:00–21:00 in summer
- ●Batteries and inverters sealed until installation day — heat degrades pre-installed equipment
- ●+15% labour cost factored into CAPEX for June–September installations
Step 05 — 6 Weeks
Commissioning & NOC
Commissioning is the final gate before the system begins generating credits. DEWA conducts a commissioning witness test to verify that protection relays, inverters and the bidirectional meter function correctly. Only after this test — and the formal issue of the No-Objection Certificate — does the system go live and Shams Dubai net metering credits begin.
DEWA Commissioning Witness Test
All protection functions tested under DEWA supervision. Auto-disconnect on grid fault, anti-islanding and relay co-ordination verified.
Bidirectional Meter Installation
DEWA installs the smart bidirectional meter that records both import and export, enabling Shams Dubai net metering credits at AED 0.38/kWh.
Client Training
sun2X trains the client's facilities management team on the monitoring dashboard, alarm response and routine checks.
Phase Three
Handover & Operations
Where the financial returns are actually realised
Phase 3 is where the project transitions from a construction project to a revenue-generating asset. Most contractors consider their job done at handover — sun2X considers handover the beginning of its most important commitment. The financial model built in Phase 1 assumed a specific system performance over 25 years. Phase 3 is the operational framework that ensures that assumption is met.
Step 06 — 25 Years
Handover & O&M Contract
The O&M contract is not an afterthought — it is the mechanism that protects the client's investment over the asset's lifetime. In UAE conditions (50°C ambient, Shamal dust, high UV), a system without structured maintenance degrades significantly faster than the financial model assumes.

Frequently Asked Questions
How long does a complete project take in Dubai?
From the initial feasibility study to energisation: approximately 47 weeks (9 + 10 + 10 + 12 + 6). The 25-year O&M contract then begins at handover.
Can we start with Phase 1 without committing to the full project?
Yes. sun2X delivers the Phase 1 feasibility and business case as a paid service, within 2 weeks of site visit. The fee is fully credited toward your project if you proceed — no obligation to continue. It is the right starting point for any client evaluating a renewable energy investment.
Why does Phase 2 take 38 weeks — that seems long?
The DEWA LOC alone takes 4–8 weeks; the authority NOC adds another 3–6 weeks. Equipment procurement for Tier-1 UAE-rated components runs 6–8 weeks. Summer installation restrictions add scheduling complexity. 38 weeks is realistic — projects that are promised faster usually either skip steps or face delays that cost more in the end.
What is included in sun2X's O&M contract?
Quarterly panel cleaning, battery filter replacement and thermal imaging; annual IV curve test, battery capacity test, BMS firmware update and cable re-torque; 24/7 NOC remote monitoring; and a monthly performance dashboard with solar yield, battery SOH, CO₂ savings and AED savings reporting.
