Solar + Battery for Telco Towers
Malaysia's ~10,000 unmanned tower sites run on diesel gensets costing RM 18K–72K per site per year. Trexon's solar + battery hybrid systems cut that by 60–85% — with 24/7 remote monitoring already built in.
4 reasons diesel is your biggest tower problem
Escalating Diesel Opex
Diesel prices are volatile and structurally rising. Each unmanned tower site burns RM 18K–72K/year in fuel alone — 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.
