Support & Resource Center

Under Dubai Electricity and Water Authority's (DEWA) Shams Dubai initiative, your solar PV system is connected directly to the Dubai utility grid via a bi-directional smart meter. When your solar panels generate more electricity than your villa or facility currently consumes during peak daylight hours, the surplus energy is automatically exported into the DEWA grid.

This exported energy is credited against your monthly electricity consumption at parity with current consumption tariffs. If total generation exceeds your monthly usage, surplus credits roll over to subsequent billing cycles indefinitely. Petronix Solar manages the entire end-to-end DEWA design submission, NOC acquisition, structural inspection, and final smart meter commissioning.

All solar photovoltaic cells experience a temperature coefficient where voltage slightly drops as ambient surface heat increases above the Standard Test Condition (25°C). In conventional P-type PERC panels, this loss can reach 0.35% to 0.40% per degree Celsius.

To overcome this UAE desert climate challenge, Petronix Solar exclusively installs N-Type TOPCon and Heterojunction (HJT) bifacial modules, which feature industry-leading temperature coefficients as low as -0.29%/°C to -0.26%/°C. Combined with engineered elevated mounting brackets that promote under-module passive airflow cooling, our installations maintain superior specific yield throughout June, July, and August.

Due to airborne sand, dust accumulation, and coastal humidity (which can cement fine particulate onto the glass), soiling in the UAE causes between 8% to 22% generation loss if neglected. We recommend:

• Residential Villas: Professional cleaning every 3 to 4 weeks during dusty periods, or monthly during winter months.
• Commercial & Industrial Warehouses: Bi-weekly cleaning schedules or automated robotic brush systems for large surface areas.

Cleaning must strictly use demineralized / reverse-osmosis (RO) purified water with specialized micro-fiber rotary brushes. Using untreated municipal tap water causes calcium and mineral calcification scale, permanently scorching anti-reflective glass coatings.

Standard grid-tied on-grid solar systems are legally mandated by DEWA and international electrical standards (IEC 62116) to shut down automatically within milliseconds of a grid outage (known as anti-islanding protection). This prevents accidental back-feeding of live electricity into utility transmission lines where technicians may be performing emergency line repairs.

If you require uninterrupted emergency backup power during grid failures, Petronix Solar installs Hybrid Solar Systems with integrated Lithium Iron Phosphate (LiFePO4) Battery Energy Storage and an automated transfer switch (ATS). This isolates your critical circuits from the grid and powers air conditioning, refrigeration, lighting, and security systems continuously.

No. Petronix Solar collaborates with accredited roofing waterproofing specialists to ensure all roof warranties remain 100% intact. For concrete flat roofs common across Dubai villas and commercial premises, we utilize aerodynamic ballasted mounting systems or non-penetrative pre-cast concrete plinths that rest on high-density EPDM protective barrier mats—requiring zero membrane punctures.

For corrugated metal industrial roofs (standing seam or sandwich trapezoidal sheets), we employ specialized structural clamps (e.g. S-5! standing seam clamps or certified EPDM-gasketed rivet fixings) accompanied by our proprietary 5-Year Workmanship Waterproofing Guarantee.

Payback periods depend primarily on your current DEWA slab tariff bracket:

• Residential Villas (Higher DEWA slab brackets): Typical simple payback period is between 3.2 to 4.5 years, with immediate electricity bill reductions of 50% to 85%.
• Commercial & Industrial Facilities: Typical payback is 3.5 to 5.0 years. Over the 25-to-30-year operational life of Tier-1 equipment, clients achieve an internal rate of return (IRR) typically exceeding 20% to 26%.

All Petronix Solar engineering proposals include an hourly 8,760-hour PVsyst simulation modeling exact solar shading, local irradiance, and projected net DEWA bill cashflows.

Every system commissioned by Petronix Solar comes equipped with a Wi-Fi or 4G LTE IoT Smart Dongle directly linked to the central inverter. Homeowners and facility engineers receive credentials to our mobile app (iOS and Android) and cloud web portal (e.g. FusionSolar, SMA Sunny Portal, or SolarEdge Monitoring).

The application displays real-time generation in kW, daily and cumulative kWh energy yield, direct CO₂ emissions avoided, and real-time alerts if string voltage drops or an inverter fault code is registered. Our technical NOC simultaneously monitors these telemetry feeds 24/7 for proactive diagnosis.
