Frequently Asked Questions
Common questions about the 10 kWp solar system in Malaysia
What's Inside a 10kW Solar System: Component Breakdown
A 10kWp system in Malaysia is typically assembled from 20–24 panels, a single string inverter or dual micro-inverters, and standard residential mounting hardware. Here is exactly what Trexon supplies and installs:
Solar Panels
17 × Jinko 620 W N-Type Tier-1 monocrystalline panels (10.54 kWp approved residential configuration)
25-year linear power output warranty. Efficiency 21–22.5%. Module-level SIRIM MS IEC 61215.
String Inverter
1 × correctly sized Solis string inverter for solar-only scope, or Huawei SUN2000 hybrid platform when selected
10-year standard warranty (extendable to 15–25 years). Efficiency 98.6%+. Remote monitoring included.
Mounting System
Aluminium rail system (Esdec, K2 Systems, or equivalent) for concrete/metal decking or standing-seam roofs
Wind load rated to 150 km/h for Malaysian building code (MS 1553). Stainless steel fasteners.
DC Cabling
TUV-certified 4 mm² solar-rated DC cable (red/black), UV-resistant, rated 1,500V DC
All cabling run through conduit where exposed. MC4 connectors with IP68 rating.
AC Isolation & Protection
SIRIM-certified AC isolator, surge protection device (SPD), and TNB-compliant AC distribution board connection
Required by TNB for Solar ATAP approval. Installed by licensed electrician (Wireman).
Bidirectional Smart Meter
Supplied and installed by TNB upon Solar ATAP commissioning
Records both import (grid to home) and export (solar to grid) for accurate billing.
Real Monthly Savings Example: RM 700 TNB Bill
A homeowner in Selangor with a RM 700/month TNB bill installs a 10kWp system. Their daily consumption is approximately 50 kWh. Here is what changes in Month 1:
40–45 kWh
Daily Solar Generation
(5 peak sun hours × 10 kWp × 0.8 efficiency)
30–35 kWh/day
Self-Consumed
Offset directly against Tariff A rate
8–12 kWh/day
Exported to TNB
Credited at Energy Charge rate
RM 120–180
New Monthly Bill
Down from RM 700 — 75%+ reduction
Annual savings: approximately RM 6,240–7,000. At an installed cost of RM 28,000–33,000, payback period is 4.2–5.3 years. 25-year total savings exceed RM 170,000 after accounting for 0.5% annual panel degradation.
10kW vs 8kW vs 12kW — Which System Size is Right?
The 10kWp system sits in the sweet spot for Malaysian homes with RM 500–900 monthly bills. Use this comparison to confirm it is the right fit — or see whether stepping up or down makes more financial sense.
| Specification | 8kWp | 10kWp (This Page) | 12kWp |
|---|---|---|---|
| Panel count | 16–20 | 20–24 | 24–28 |
| Monthly generation (avg) | 880–960 kWh | 1,100–1,200 kWh | 1,320–1,440 kWh |
| Ideal monthly TNB bill | RM 400–600 | RM 600–900 | RM 800–1,200 |
| Typical installed price | RM 22,000–26,000 | RM 28,000–33,000 | RM 34,000–40,000 |
| Roof area required | 38–45 sqm | 50–60 sqm | 60–72 sqm |
| Est. payback period | 4–5.5 years | 4.2–5.3 years | 4.5–5.5 years |
| 25-year savings (est.) | RM 120,000–140,000 | RM 160,000–185,000 | RM 190,000–220,000 |
| ATAP MAQ (30-day cycle) | 600 kWh | 750 kWh | 900 kWh |
Roof Space Requirements for a 10kW System
A 10kWp system requires 50–60 sqm of usable, shadow-free roof area. "Usable" means the area is free from HVAC units, water tanks, skylights, and vent pipes — and is not shadowed by adjacent buildings, trees, or parapet walls between 9 am and 3 pm.
Flat concrete roof
Excellent
Most common in Malaysia. Panels mounted at 10–15° tilt using ballast frames. No roof penetration needed. Easy maintenance access.
Metal standing-seam (zincalume / IBR)
Excellent
Clamp-on mounting — zero penetrations. Ideal for factories, warehouses, and terrace house extensions. Fast installation.
Cement fibre / asbestos tile
Good (with care)
Requires careful hook mounting to avoid cracking. Trexon inspects tile condition before proceeding. May add RM 1,500–3,000 to cost.
Clay / ceramic tile (genteng)
Good
Tiles lifted and replaced around hooks. Slight roof penetration — properly flashed and waterproofed. Common in semi-D and bungalow homes.
Low-pitch hip roof
Good
Works well for north-facing or east/west-facing panels if south-facing area is limited. Minor generation impact (5–10% vs optimal south-facing).
Shingle / bitumen roof
Limited
Common in older terrace houses. Condition assessment critical — if roof is near end-of-life, we recommend re-roofing before solar. Trexon advises honestly.
10kW Solar System — Detailed FAQ
How much does a 10kW solar system cost in Malaysia in 2026?
Trexon quotes a 10kWp-class residential system in either the Solis Value or Huawei Premium ecosystem. The installed total includes Tier-1 panels, the selected inverter, mounting, protection, commissioning, and the Solar ATAP application scope stated in the proposal.
How much can a 10kW solar system save on my TNB bill per month?
For a home with a RM 600–900 monthly TNB bill, a 10kWp system typically reduces the bill by RM 450–700 per month — a 65–80% reduction. The exact savings depend on: your daily electricity usage pattern (peak hours vs off-peak), roof orientation (south-facing is optimal), and how much of your generation is self-consumed vs exported. Use our solar calculator for a precise estimate.
How long is the payback period for a 10kW solar system?
Payback period for a 10kWp system in Malaysia is typically 4.2–5.3 years, depending on your TNB tariff rate, self-consumption ratio, and system cost. Higher-consumption homes (RM 700–900/month bills) achieve payback faster because more of the generation is consumed directly — which is credited at the higher domestic tariff rate rather than the lower SMP export rate.
What warranties come with a 10kW solar system from Trexon?
Every Trexon 10kWp system includes: 25-year linear power output warranty on panels (guaranteed to produce 80%+ of rated power in Year 25), 10-year product warranty on inverter (extendable), 5-year workmanship warranty on installation (roof penetrations, cabling, mounting), and 1-year performance guarantee — if your system does not generate within 5% of projected output in Year 1, we investigate and rectify at no charge.
