Off-Grid Solar Coverage Areas in Malaysia
We design off-grid systems for four key regions. In East Malaysia (Sabah and Sarawak), installation is delivered through local partners, who handle the local logistics and utility applications.
SabahPriority Region
Areas served: Kundasang, Ranau, Sandakan, Kota Kinabalu, Tawau, Lahad Datu
SarawakPriority Region
Areas served: Kapit, Belaga, Bario, Kuching, Sibu, Miri, Bintulu
Peninsular Highlands
Areas served: Cameron Highlands, Frasers Hill, Genting Highlands, Bukit Tinggi
Malaysian Islands
Areas served: Langkawi, Tioman, Perhentian, Redang, Pangkor, Sipadan
Sabah — Rural Sabah presents unique energy challenges: remote longhouse communities, highland farms, and plantation worker quarters far from SESB grid lines. Through local partners we can serve Kundasang, Ranau, Sandakan, Tawau, and Lahad Datu districts.
Sarawak — Through local partners we serve the Kapit and Belaga river communities, Bario highland settlements, and coastal towns including Sibu, Miri, and Bintulu. SEB grid coverage gaps make off-grid solar the practical choice.
Peninsular Highlands — Cameron Highlands homes, Fraser's Hill retreats, and Genting-area properties benefit from off-grid or hybrid systems due to frequent outages and elevated diesel costs at altitude.

Off-Grid Solar FAQ — Soalan Lazim Sistem Solar Off-Grid Malaysia
Common questions about off-grid solar in Malaysia, answered by our team.
How much does off-grid solar cost in Malaysia?
Off-grid solar systems in Malaysia are sized and quoted per site — there are no fixed package prices. We quote from your load list or a site survey; the price depends on your daily energy use, the battery autonomy you need, site access and logistics.
Can off-grid solar power air conditioning?
Yes, with the right system size. A 5 kWp system with 10 kWh battery can run 1-2 small AC units. For multiple ACs or central air conditioning, we recommend 10+ kWp systems with 20+ kWh battery banks. Resort systems are sized per site to handle heavy AC loads.
Which battery type suits off-grid solar in Malaysia?
We exclusively use LiFePO4 (Lithium Iron Phosphate) batteries. They offer 15+ year lifespan, 6,000+ charge cycles, excellent performance in Malaysian heat, and have a low fire risk. While more expensive upfront, the long lifespan makes them more economical than lead-acid alternatives.
How long do off-grid batteries last?
Our LiFePO4 batteries are rated for 6,000+ cycles, translating to 15-20 years of daily use. Battery warranty follows the manufacturer's terms stated in your quote. In contrast, lead-acid batteries typically last only 3-5 years and require more maintenance.
Is off-grid solar available in Sabah and Sarawak?
Yes! We serve East Malaysia. In Sabah and Sarawak, installation is delivered through local partners, covering areas such as Kota Kinabalu, Sandakan, Kuching, and Sibu, including remote longhouse communities, plantations, and island locations.
How does remote monitoring work for off-grid systems?
All our systems include WiFi/4G-enabled monitoring. You can track energy production, battery levels, and system health from your smartphone. Remote monitoring lets us diagnose many issues remotely before dispatching a service technician.
Can I expand my off-grid system later?
Absolutely. Our systems are designed for modular expansion. You can add more solar panels, increase battery capacity, or upgrade inverters as your needs grow.
What maintenance do off-grid systems require?
Minimal maintenance is required. Solar panels should be cleaned 2-4 times yearly (more in dusty areas). LiFePO4 batteries are maintenance-free. We offer annual service packages that include inspection, cleaning, and system optimization.
Do you offer financing for off-grid systems?
Yes: outright purchase, 0% credit-card instalment plans of up to 24 months with participating banks, bank loans for larger systems, and hire-purchase agreements for companies (Mitsubishi HC Capital). We do not offer rental. Every route starts with the booking (RM2,000 for homes; 20% of the system price, capped at RM20,000, for commercial projects).
What happens during extended cloudy periods?
Battery autonomy — how long the system runs without sun — is chosen in the design for your site and loads, and confirmed in your quote. For critical loads we can integrate generator backup or design a larger battery bank.

Trust & Quality Assurance
Does Trexon handle Solar ATAP and TNB paperwork?
Yes. Trexon prepares the Solar ATAP, TNB, ST, and grid-connection documentation needed for your project. Residential systems use Tier-1 panels with a Solis, Huawei, Sungrow or GoodWe inverter ecosystem.
What warranty does Trexon provide?
We provide a comprehensive warranty package: 30-year performance warranty on solar panels (at least 87.4% of rated output at year 30 under the Jinko warranty terms), 12-year panel product warranty, 10-year inverter warranty, and 5-year workmanship warranty on installation.
What happens if my solar system underperforms?
If output drops, check the monitoring app (Solis Value uses SolisCloud and Huawei Premium uses FusionSolar) and contact Trexon support; workmanship and equipment warranties apply. Trexon commissions the selected platform and provides the monitoring scope stated in the accepted proposal.
What is an off-grid solar system?
An off-grid system is an independent power setup that doesn't rely on the TNB grid. It uses solar panels, batteries, and an inverter to generate and store energy.
How long do solar batteries last?
Our LiFePO4 batteries are rated for 6,000+ charge cycles, roughly 15-20 years of daily use. Battery warranty follows the manufacturer's terms stated in your quote.
Can off-grid systems work year-round in Malaysia?
Yes. Malaysia gets consistent sun year-round. Even during monsoon season, solar output remains 30-50% of peak. Battery storage handles cloudy days.
How quickly do off-grid systems pay for themselves?
Payback varies by site, load, diesel cost and system size. We estimate it for your site in your quote.
What is included in the installation?
Full installation includes solar panels, battery bank, inverter, wiring, monitoring system, and commissioning with training.
Do you offer after-sales service?
Yes. Systems include remote monitoring, and we offer annual maintenance packages and warranty support.
