Shanghai Haiwan Telecom Tower Solar & Storage Integration

At the Haiwan branch of a telecommunications bureau in Shanghai’s Fengxian district, the solar-and-storage upgrade focused on a different asset from a conventional rooftop project: the existing tower structure. Huijue Group’s project record describes a lightweight tower-mounted photovoltaic arrangement coupled with energy storage and remote monitoring. Its purpose was to introduce on-site generation within a telecom facility where space and ongoing operation already shaped the installation.

Why the mounting surface matters

The visible arrangement places module groups at more than one height, leaving the surrounding facility recognizable as a telecom site rather than a new stand-alone solar field. This is the defining feature of the case. It illustrates a possible installation route when additional ground area or equipment-room roof space is limited.

Reusing tower space does not remove the need for structural engineering. Module area, bracket geometry, wind exposure, attachment loads, corrosion protection and climbing access all affect suitability. For a new location, the tower owner’s approval and a competent structural review are prerequisites; the existence of this project is not evidence that any telecom tower can accept the same layout.

Mounting approach

Lightweight tower-mounted photovoltaic integration

Energy functions

On-site solar generation, energy storage and self-consumption

Supervision

Remote equipment-status visibility and automatic fault alarms

Published capacity

No project-specific PV or battery capacity is stated in the available record

The project description emphasizes a compact installation and retaining equipment-room space. It also identifies lower purchased electricity and reduced maintenance effort as intended benefits. Without the load trace, generation meter readings and operating history, those objectives should not be turned into a numerical saving, a guaranteed return or a universal zero-interruption installation promise.

A tower retrofit has several separate design boundaries

From project photograph to a buildable brief

The photograph answers where the modules were placed, but it does not answer how another operator should size its array. A credible new proposal starts with a measured telecom load, the available mounting envelope and a solar assessment that includes shading between module tiers. Generation should then be checked against daytime demand, battery charging opportunities and the reserve held for communication continuity.

1. Supply a tower elevation, photographs and the structural information available to the owner.
2. Mark antenna zones, feeder ladders, maintenance routes and mounting exclusions.
3. Provide the telecom load profile, existing supply topology and battery operating policy.
4. Agree monitoring points and permitted commissioning windows before installation planning.

Relevant current families include the 4G/5G multi-source hybrid power system and outdoor photovoltaic energy cabinet. A suitable combination depends on the station’s voltage, load, storage strategy and approved interfaces. Huijue Group can review cabinet layout, cable entries, labels and drawing-based mechanical requirements alongside the power scope. Discuss a tower-space retrofit with the site drawings rather than selecting equipment from the photograph alone.
