Solar + Battery for Telco Towers
Many of Malaysia's unmanned tower sites still run on diesel gensets. Trexon's solar + battery hybrid systems cut that diesel use — the offset for each site is modelled from its own load and fuel data, with remote monitoring built in.

4 reasons diesel is your biggest tower problem
Escalating Diesel Opex
Diesel prices are volatile. Every litre burnt at an unmanned tower site is a direct hit to tower EBITDA.
Diesel Theft & Pilferage
Remote, unmanned sites are prime targets. Fuel theft adds unbudgeted opex, triggers SLA failures, and is nearly impossible to audit without on-site presence.
ESG & Scope 1 Emissions Pressure
BURSA ESG disclosure, Axiata Net Zero 2050, and customer CSRD reporting all require Scope 1 reduction at the asset level. Diesel gensets are the loudest line item.
Generator Maintenance Burden
Scheduled servicing, unplanned breakdowns, and spare-parts logistics across thousands of remote sites eat engineering headcount and inflate field opex.
Hybrid system tiers
Right-sized for every tower class. All systems are genset-compatible — diesel runs only when solar + battery can't cover load.

From site audit to live monitoring
1
Site Audit
Our engineers survey load profiles, grid availability, structural capacity, and shading at each candidate site.
2
Engineering Design
Site-specific PV + battery sizing, single-line diagrams, and a 20-year financial model built for tower EBITDA.
3
Installation
End-to-end EPC delivery — civil, electrical, and commissioning — with minimal downtime to active tenants.
4
Remote Monitoring
Monitoring streams real-time yield, battery state, and genset runtime data to your NOC (scope agreed per project).
Planning Diesel Replacement at Tower Sites
Replacing diesel at a tower site starts with the actual load at each site, fuel logistics and the autonomy the equipment requires. Use our diesel calculator to frame current genset running costs, read how to replace a diesel genset with solar and storage, and see how commercial battery storage provides overnight autonomy.
Sites without a reliable grid connection are covered in our off-grid solar page, and multi-source sites that combine solar, storage, grid and generator are explained under microgrid planning. You can also compare financing options before requesting a site assessment.
