U Mobile and HLGY Energy have signed a memorandum of understanding to deploy a private 5G network at a solar farm, with drones and artificial intelligence performing the inspection work.

The agreement, first reported by Nasi Lemak Tech, positions the Malaysian mobile operator at the intersection of two enterprise verticals carriers have chased for years: private cellular infrastructure and renewable-energy operations.

What does the MoU actually cover?

The publicly disclosed details narrow the partnership to three layers. A private 5G network provides connectivity across the solar facility. Drones carry out flight-based inspections of photovoltaic arrays. AI software analyses the captured imagery for defects.

Specific sites, capacity figures, contract value, and rollout timelines did not appear in the initial report. Both parties framed the agreement as a commitment to technical and commercial pilots rather than a turnkey deployment.

Why private 5G at a solar farm?

Solar generation sites spread across hectares of reflective metallic surfaces. Standard Wi-Fi fails to deliver consistent coverage across that footprint, and cellular signals suffer the same fate without purpose-built infrastructure.

Private 5G solves three problems at once. Coverage scales across the entire site without dropouts. Latency stays low enough for real-time drone control. Capacity supports high-resolution thermal and visual imagery sent back to a central analytics engine.

For drone operations specifically, the network closes a gap that has historically forced operators to fly store-and-forward missions, where aircraft capture data onboard and upload only after landing. Live uplink changes the economics of large-scale inspections.

What does this change for U Mobile?

Enterprise contracts outside consumer mobile services have become a strategic priority for Malaysian carriers. Multi-year private network deals deliver predictable revenue and lock customers into operator-managed radio infrastructure.

U Mobile has pursued that path across ports, manufacturing, and logistics in recent deployments. The HLGY Energy agreement extends the strategy into power generation, where long asset lifecycles favour stable service relationships.

The MoU also functions as a reference deployment. Successful execution at a single solar site creates a bidding template for similar work with peer energy operators across the country.

What does it change for solar operations?

Thermographic inspections have long been standard practice in solar asset management. Ground crews walk rows of panels with handheld cameras, capturing temperature anomalies that signal failing cells, hot spots, or soiling.

Drone-based workflows compress that process. Aerial surveys cover more ground in less time. AI image analysis flags defects that human reviewers would miss or take longer to triage.

A private 5G network underneath those drones adds a layer of automation legacy approaches cannot match. AI sorting happens at the edge or in near-real-time at a central server, rather than after the aircraft lands and offloads data.

What does the regulatory backdrop look like?

Malaysia's communications regulator has moved in recent years to allocate dedicated private 5G spectrum to enterprises and operators that meet deployment and rollout thresholds. The framework has unlocked a pipeline of pilots across verticals including manufacturing, ports, healthcare, and education.

Energy infrastructure now joins that list. The shift matters because spectrum availability, not technology readiness, has historically gated private 5G rollouts in the country.

Looking ahead

The MoU commits U Mobile and HLGY Energy to pilot stages before any commercial-scale rollout. Neither party disclosed network configuration details, equipment vendors, or site locations in the initial reporting.

Malaysia's energy transition plans place solar generation at the centre of new capacity additions into the next decade. Private 5G deals tied to that buildout are likely to track the volume of new solar projects coming online, with each installation offering carriers a candidate site for recurring enterprise revenue.
