Solar PV Testing Services in Oman | Standards, Projects & O&M for Vision 2040

AQ Electric brings specialist solar PV testing services to the Omani market backed by more than 1.0 GW of PV project experience across the MENA region — and by working relationships with the very developers now shaping Oman’s solar future. ACWA Power, for whom AQ Electric has delivered thermal drone inspection and technical services on utility-scale Egyptian projects, is the lead developer of Oman’s landmark 1 GW Manah I and Manah II solar plants. As the Sultanate accelerates toward its Vision 2040 renewable-energy targets, the demand for rigorous, IEC-compliant solar testing services in Oman — from commissioning through long-term solar power plant operation and maintenance — has never been greater.

This guide explains everything an EPC contractor, IPP developer, asset owner, or lender’s technical advisor needs to understand about solar PV testing services in Oman: the scale and structure of the Omani solar market, the institutions and procurement framework, where solar capacity is concentrated, why testing and solar power plant operation and maintenance matter especially in Oman’s climate, how IEC 62446-1 applies in the Omani context, and how AQ Electric delivers the full testing scope drawing on its proven regional track record. Whether you are commissioning a plant in the Al-Dhahirah desert, investigating underperformance at an Ibri installation, or seeking a long-term O&M partner, this is the practical reference for getting solar PV testing right in the Sultanate.

Oman’s Solar Market and Vision 2040

Oman has emerged as one of the most purposeful solar markets in the Gulf, driven by a clear national strategy and some of the best solar resource anywhere in the world. Under Oman Vision 2040 and the National Energy Strategy, the Sultanate aims to source 30% of its electricity from renewables by 2030, rising to 60–70% by 2040 and a full 100% by 2050. This trajectory makes solar testing services in Oman a structural, long-term requirement rather than a passing opportunity — every gigawatt built and operated over the coming decades will need commissioning, inspection, and ongoing solar power plant operation and maintenance.

The resource underpinning this ambition is exceptional. Oman receives over 2,800 hours of sunshine per year and enjoys high Global Horizontal Irradiation across the country, making it naturally suited to utility-scale solar. As of early 2026, the Sultanate’s operational renewable projects — the Ibri II, Manah I, Manah II solar plants, and the Dhofar Wind Power Project — have a combined capacity of around 1,550 MW, representing roughly 9.26% of the country’s electricity generation. This is a solid base, and the pipeline ahead is far larger.

The scale of Oman’s longer-term ambition is captured in the Oman Power and Water Procurement Company’s planning: a phased solar programme targeting 4.5 GW by 2027 and building toward a total of 13.5 GW by 2040, developed primarily across the Al-Dhahirah and Al-Wusta governorates. In June 2026, the Sultanate moved to procure a further 1,500 MW of solar capacity, and OQ Alternative Energy expanded its renewable portfolio by more than 2,000 MW during 2025 through new power purchase agreements. Each of these projects represents fresh demand for solar PV testing services in Oman across the full project lifecycle.

Landmark Omani Solar Projects

Understanding the Omani solar landscape means understanding its flagship projects — each of which represents a substantial requirement for solar PV testing services in Oman and for long-term solar power plant operation and maintenance.

Manah I and Manah II — 1 GW (ACWA Power)

The Manah I and Manah II solar plants, located in the Manah region of the Al-Dhakhiliyah governorate, together contribute approximately 1,000 MW to Oman’s northern grid — each station exceeding 500 MW. Developed by a consortium led by Saudi Arabia’s ACWA Power, they mark a new benchmark in Oman’s renewable-energy journey. For AQ Electric, the Manah projects are especially significant: ACWA Power is an established AQ Electric client, for whom we have delivered thermal drone inspection and technical services on Egyptian utility-scale projects. This existing relationship with the lead developer of Oman’s largest solar complex demonstrates exactly the kind of credibility that solar PV testing services in Oman require.

Ibri II Solar Plant — 500 MW

The Ibri II Solar PV IPP, with a capacity of 500 MW, began commercial operations in August 2021 and was for a time among the largest single-site solar plants in Oman. Located in the Al-Dhahirah governorate, it supplies power to tens of thousands of homes and has proven the viability of large-scale solar in Omani conditions. As an early-mover plant now several years into operation, Ibri II is precisely the kind of asset where ongoing solar power plant operation and maintenance — periodic testing, thermography, and performance verification — becomes critical to protecting long-term yield.

Ibri III with Battery Storage — Under Development

The Ibri Solar Project III is expected to begin operations in the second quarter of 2027 and will include a 100 MW battery energy storage system, enhancing grid flexibility. A defining 2026 milestone is the launch of Oman’s first utility-scale solar project integrated with a 1,000 MWh battery energy storage system in Ibri — directly addressing solar intermittency. Battery-integrated plants add new testing and commissioning requirements that a capable solar testing partner must be equipped to handle.

North Oman Solar — 128 MW

Construction is advancing on the 128 MW North Oman Solar Power Project, part of the broader push to diversify generation and enhance energy security. Alongside it, the Al Kamil Solar IPP and major wind farms in Mahoot, Duqm, and Sadah form part of the 1,600 MW of new solar and wind capacity procured as of early 2026.

The Regulatory and Procurement Landscape

Delivering solar testing services in Oman means working within a well-defined institutional framework built around the Sultanate’s single-buyer power model.

• Nama Group — the state-owned holding company overseeing Oman’s electricity sector, parent to the key procurement and transmission entities.
• OPWP / PWP — the Oman Power and Water Procurement Company (also referred to as PWP) is the sole purchaser of electricity from independent power plants, running the competitive IPP tenders and signing the power purchase agreements behind Oman’s utility-scale solar.
• Authority for Public Services Regulation (APSR) — the sector regulator responsible for licensing and technical standards.
• OQ Alternative Energy — the renewable-energy arm of the state energy group OQ, an active developer expanding Oman’s renewable portfolio.
• Petroleum Development Oman (PDO) — an early pioneer of large-scale solar in Oman, including landmark projects supporting oilfield operations.

Oman’s procurement runs primarily through OPWP’s competitive IPP tenders, in which developers bid to finance, build, own, and operate plants and sell electricity under long-term PPAs. As with the wider Gulf, the technical standard expected for grid-connected commissioning converges on IEC 62446-1, and bankable projects require testing documentation that satisfies both OPWP’s technical requirements and the due-diligence standards of international lenders. Solar PV testing services in Oman must be documented to this bankable standard — a documentation fluency that AQ Electric brings from lender-financed projects across the region.

Where Omani Solar Is Concentrated

Oman’s solar capacity is concentrated in specific high-irradiance regions where resource, land, and grid capacity converge — and understanding this geography is essential to understanding what solar PV testing services in Oman need to be equipped for.

• Al-Dhahirah governorate (northwest interior) — home to the Ibri II and Ibri III projects, a core solar hub with excellent irradiance and established grid infrastructure.
• Al-Dhakhiliyah governorate (Manah) — site of the 1 GW Manah I and II complex, the largest concentration of solar capacity in the country.
• Al-Wusta governorate (central desert) — a primary target for the phased build-out toward 13.5 GW, with vast land availability and strong resource.
• Dhofar (south) — associated more with wind (the Dhofar Wind Power Project) but increasingly part of the integrated renewable landscape as the Rabt north-south grid interconnection links the regions.
• Duqm and the Special Economic Zone — an emerging industrial and energy hub, including green-hydrogen-linked renewable development.

Each region presents its own operating environment. The interior deserts of Al-Dhahirah and Al-Wusta combine extreme heat with heavy dust; the coastal areas add humidity and salt exposure. A single national testing approach does not fit every site — regional familiarity and Gulf-climate experience matter, which is exactly what AQ Electric’s work across Saudi Arabia and Egypt provides.

Why Solar PV Testing Services Matter More in Oman

The generic global playbook for solar testing was written around temperate operating environments. Applied unmodified to Oman, it leaves critical risks unmanaged. AQ Electric’s experience across the Gulf — particularly on the Wadi Ad Dawasir project in neighbouring Saudi Arabia, whose climate closely mirrors Oman’s interior — has produced a testing approach adapted specifically to these conditions.

Extreme Heat and Its Effect on Testing

Oman’s interior experiences some of the highest sustained ambient temperatures of any solar market, with summer highs regularly exceeding 45 °C and module operating temperatures crossing 70 °C. This affects solar testing services in Oman in two ways: expected values for open-circuit voltage and operating current must be temperature-corrected using Oman-specific profiles rather than standard test conditions, and thermal stress reveals defects — hot connections, cell cracks, bypass diode failures — that would remain hidden in cooler climates.

Dust and Soiling

Soiling is one of the most significant Oman-specific issues. In the interior deserts, dust deposition can reduce module output substantially within weeks without cleaning. Soiling ratio measurement, cleaning-cycle optimisation, and post-cleaning performance verification are therefore core deliverables of solar testing services in Oman — and central to effective solar power plant operation and maintenance in the Sultanate.

Coastal Humidity and Salt

Plants near Oman’s extensive coastline — including areas around Duqm and Dhofar — face humidity and salt-spray corrosion on structures, junction boxes, and combiner enclosures. Corrosion inspection becomes a critical periodic activity in these environments.

Remote Sites and Response Logistics

Utility-scale plants in Al-Dhahirah and Al-Wusta are far from major population centres. A testing or O&M provider without genuine regional mobility either delivers late or subcontracts the actual work — both of which erode the value proposition. AQ Electric’s regional equipment pool and Gulf field experience are structured precisely to serve remote Gulf sites efficiently.

The Full Scope of Solar PV Testing Services in Oman

Comprehensive solar testing services in Oman span the entire project lifecycle, from factory acceptance through commissioning to periodic operational testing. AQ Electric delivers the complete scope, drawing on field-proven methodology from across its 1.0 GW of regional project experience.

Testing and Commissioning

The core of solar testing services in Oman is the commissioning test regime — visual inspection, earthing continuity, polarity verification, open-circuit voltage and operating current measurement, and insulation resistance testing on every string, all documented to IEC 62446-1. This is AQ Electric’s flagship testing and commissioning service.

IV Curve Tracing

IV curve tracing is the definitive diagnostic for identifying underperforming strings and pinpointing the specific fault mechanism. On large Omani plants like Manah and Ibri, systematic IV curve tracing across the array is essential to verify the DC side is delivering full power. AQ Electric provides dedicated IV curve tracing services as a core part of its solar testing offering.

Thermographic and Drone Inspection

At Omani project scale, aerial thermographic inspection by drone is the only practical way to scan hundreds of thousands of modules for hot spots and connection faults within a commissioning or maintenance schedule. AQ Electric’s drone inspection services deliver rapid, comprehensive thermal assessment — the same capability delivered for ACWA Power on Egyptian projects.

Quality Assurance: FAT and SAT

Factory Acceptance Testing and Site Acceptance Testing verify that modules, inverters, and transformers meet specification before and after installation. AQ Electric’s FAT and SAT services protect Omani projects from defective equipment entering the plant.

Third-Party Inspection

Independent third-party inspection provides owners, lenders, and insurers with objective assurance that a plant has been built and tested correctly. AQ Electric’s third-party inspection services deliver this independent validation across Omani solar projects.

IEC 62446-1 in the Omani Context

All credible solar testing services in Oman anchor on the international standard IEC 62446-1, which defines the minimum testing, documentation, and inspection requirements for grid-connected PV systems. On every Gulf project, AQ Electric applies this standard as the baseline commissioning framework. For a full walkthrough of the standard and its three testing categories, see AQ Electric’s complete IEC 62446-1 guide.

In the Omani context, three considerations shape how the standard is applied: temperature-corrected expected values calculated against Oman’s extreme interior temperatures; Category 2 testing (IV curve tracing and thermography) as the effective baseline for utility-scale projects rather than an optional extra; and multi-advisor documentation structured to satisfy OPWP’s technical requirements alongside international lenders’ technical advisors on bankable projects.

Solar Power Plant Operation and Maintenance in Oman

Solar testing services in Oman do not end at commissioning. The longest and most financially significant phase of any plant’s life is its operational phase — and this is where solar power plant operation and maintenance becomes critical. Effective solar power plant operation and maintenance in Oman’s harsh climate is the single most important factor in protecting a plant’s yield across its 25-to-30 year design life.

Solar power plant operation and maintenance encompasses the full set of activities required to keep a PV plant performing to specification: preventive maintenance, corrective repairs, and predictive condition-based maintenance driven by continuous monitoring data. In Oman specifically, solar power plant operation and maintenance must contend with intense desert soiling, extreme heat-driven equipment stress, and — at coastal sites — salt corrosion, making a well-designed O&M programme far more consequential than in temperate markets.

Why Solar Power Plant Operation and Maintenance Matters More in Oman

The economics are clear. Poorly-maintained modules degrade two to three times faster than well-maintained ones. Soiling alone can reduce output by double-digit percentages between cleaning cycles in the Omani desert. Inverter thermal derating in Oman’s summer conditions silently caps output at exactly the moment of peak generation. Each of these losses is preventable through a disciplined solar power plant operation and maintenance programme — and each, left unmanaged, compounds year after year to erode the returns of a plant that may have been perfectly built and commissioned.

The O&M Activities That Matter Most in Oman

A comprehensive solar power plant operation and maintenance programme for an Omani plant includes module cleaning optimisation, infrared thermographic scanning, IV curve tracing, inverter servicing, transformer testing, MV cable testing, and continuous performance monitoring with loss decomposition. AQ Electric delivers all of these through its solar operation and maintenance services. For a complete breakdown of what a best-practice solar power plant operation and maintenance programme involves across the MENA region, see our detailed solar O&M guide.

The link between testing and solar power plant operation and maintenance is direct: the same disciplines applied at commissioning — IV curve tracing, thermography, insulation testing — are repeated periodically through the operational phase to catch degradation early. This is why AQ Electric integrates testing and solar power plant operation and maintenance into a single continuous assurance service rather than treating them as separate transactions — an approach especially valuable for Oman’s early-mover plants like Ibri II that are now several years into operation.

Challenges Unique to Omani Solar Projects

Delivering solar PV testing services in Oman and sustaining solar power plant operation and maintenance in the Sultanate means confronting a distinct set of challenges that AQ Electric’s regional experience has prepared it to address.

Extreme Heat and Thermal Management

Oman’s interior summer conditions push every electrical component toward its thermal limits. Inverters derate, transformers lose headroom, and cable insulation ages faster. Testing must be scheduled around cooler windows for accuracy, and solar power plant operation and maintenance must prioritise cooling-system maintenance to prevent heat-driven output loss.

Desert Soiling and Water-Scarce Cleaning

Dust deposition in the Al-Dhahirah and Al-Wusta deserts is relentless, yet water for cleaning is scarce. Omani plants increasingly rely on dry-brush and robotic cleaning, and optimising the cleaning cycle — balancing cleaning cost against soiling loss — is a specialist O&M skill that directly affects plant economics.

Battery Storage Integration

As Oman pioneers utility-scale solar-plus-storage — including the 1,000 MWh BESS at Ibri — testing and commissioning scope expands to include battery systems and their integration with the PV plant and grid. A capable solar testing partner must be prepared for this added complexity.

Grid Integration and the Rabt Interconnection

The Rabt project linking Oman’s Main Interconnected System with the Dhofar and Duqm grids is creating a single national super-grid. Grid-code compliance testing — verifying that inverters and plants behave correctly during grid events — becomes increasingly important as more renewable capacity connects to this unified grid.

AQ Electric’s Regional Track Record

AQ Electric for Power Solutions, founded in Jordan in 2019 and expanded to Egypt in 2021, provides solar PV testing services across the MENA region and beyond, backed by over 1.0 GW of PV project experience and an ISO 9001, ISO 14001, and ISO 45001-certified management system. While Oman represents a growth market for AQ Electric, our credibility rests on a proven regional track record delivered in climates and at scales directly comparable to the Sultanate — and, crucially, on working relationships with the developers now building Oman’s solar future.

This regional depth — proven clients (including Manah’s own developer ACWA Power), proven Gulf-climate experience, and proven utility scale — is what AQ Electric brings to every conversation about solar testing services in Oman.

Choosing a Solar Testing Partner in Oman

Selecting a provider of solar testing services in Oman is a decision that shapes the bankability and long-term performance of the asset. Seven criteria consistently separate genuine specialists from generalists:

1. Gulf climate experience. Proven work in comparable heat, dust, and coastal conditions — like AQ Electric’s Wadi Ad Dawasir project in Saudi Arabia and its Aswan portfolio in Egypt.
2. ISO certifications. ISO 9001, ISO 14001, and ISO 45001 as a minimum. AQ Electric holds all three.
3. IEC 62446-1 competency. Demonstrated with sample reports in the format the provider will deliver.
4. Full in-house testing scope. Commissioning, IV curve tracing, thermographic drone inspection, FAT/SAT, and solar power plant operation and maintenance delivered in-house, not subcontracted.
5. Bankable documentation. A track record of reports accepted by lenders’ technical advisors and independent engineers.
6. Recognised developer relationships. AQ Electric’s clients include ACWA Power — lead developer of Oman’s Manah complex — along with NOMAC, SEPCO, Power China, and CEEC.
7. Integrated testing and O&M. A partner providing both commissioning testing and ongoing solar power plant operation and maintenance delivers continuous assurance across the plant’s life.
