Get QuoteTrexon Energy vs GSPARX — Honest Comparison [2026]
GSPARX is a TNB subsidiary that offers residential and commercial solar — primarily through a leasing/quotation model. Here's an honest comparison so you can decide which fits your situation.
TL;DR verdict
- Choose Trexon if you want to own your system outright with transparent prices, a 60-second AI proposal, and 11 financing options that compete with TNB-backed leasing on total cost.
- Choose GSPARX if utility ownership matters to you and you specifically want a TNB-affiliated installer, or if you prefer a long-term leasing arrangement with the national utility's subsidiary.
- Both companies are SEDA-registered and use Tier-1 components. Trexon publishes prices; GSPARX uses a quotation/calculator that requires your electricity bill before producing numbers.
- GSPARX claims 2,310+ residential installations and 340+ MWp total capacity (their own figures). Trexon's edge is a digital, self-serve buying experience with built-in EV-charger bundling.

Three areas where the difference shows up
Pricing transparency
Trexon publishes live prices on the configure and packages pages — no email-for-quote wall. GSPARX no fixed prices displayed; a calculator generates an estimate after you supply electricity bill data.
Customer experience
Trexon: 60-second AI proposal, 25+ checkout variations, WhatsApp ordering with bilingual auto-reply, real-time monitoring on day one. GSPARX: Calculator + quotation flow; no online checkout for full system purchase found on the public site.
B2B / C&I capability
Trexon: 20 industry case studies across 12 manufacturing segments, GITA tax help, NEM 3.0 included. GSPARX: Residential rooftop solar (primary) + commercial / community solar programs.
When GSPARX is the better choice
We'd rather you pick the right vendor than the loudest one. These are honest scenarios where GSPARX legitimately fits better than Trexon.
You explicitly want a TNB-affiliated installer
If your decision criteria include "must be owned by TNB" — for trust, for political-risk reasons, or because you prefer dealing with the national utility for both your bill and your solar — GSPARX is built exactly for that preference.
You're in East Malaysia (Sabah / Sarawak)
GSPARX lists all Malaysian states in its contact form. Trexon's installation crew currently focuses on Peninsular Malaysia (Selangor, KL, Penang, Johor, Kelantan, Melaka). For East Malaysia, GSPARX has the nationwide TNB footprint.
You want a long-term leasing arrangement, not ownership
GSPARX's lineage is in solar leasing/PPA-style structures backed by TNB. If you prefer not to own the system and want a utility-style monthly bill instead, that's GSPARX's lane.
You value an installer's brand-trust over digital experience
TNB is one of the most recognised brands in Malaysia. If brand recognition outweighs a faster online quote-to-install flow for you, GSPARX wins on that single dimension.
Why customers switch to Trexon
Five differentiators, each tied to something measurable on our public site.
AI-powered 60-second proposals
Gemini-AI sizes your system, picks the right inverter, and quotes a price before you finish your coffee — no sales call, no email follow-up.
11 financing options under one roof
EPF i-Saraan, PPA, Islamic, hire purchase, cash, plus five different bank green loans — picked side-by-side at checkout.
WhatsApp-first ordering
WhatsApp Business System with bilingual EN/BM auto-reply. Order, ask, escalate — all on the channel 98% of Malaysia already uses.
Real-time monitoring on every install
Customer dashboard live from day one. Track production, savings, and CO₂ avoided — no extra add-on or monthly fee.
Founder accessibility + transparent pricing
MIT-trained founder Chandra Rau is reachable directly. Live prices on /configure and /packages — no "contact us for a quote" wall.
FAQ: Trexon vs GSPARX
Is GSPARX cheaper than Trexon?+
GSPARX does not publish prices upfront — you upload your electricity bill to get an estimate, and the full number arrives after lead-capture. Trexon's prices are live on the configure and packages pages. Without an apples-to-apples spec from both, no honest cost comparison is possible.
Is GSPARX owned by TNB?+
Yes. GSPARX is a wholly-owned subsidiary of Tenaga Nasional Berhad. Trexon is privately held and independent of any utility.
Does GSPARX offer the same NEM 3.0 application as Trexon?+
Yes — as a SEDA-registered installer with TNB lineage, GSPARX handles NEM 3.0 applications routinely. Trexon also handles NEM end-to-end as part of every install.
Can I get a GSPARX quote without sharing my electricity bill?+
Based on our May 2026 review, GSPARX's calculator requires bill data to produce a meaningful estimate. Trexon's configurator lets you build a system and see prices without uploading anything.
I'm leaning GSPARX for the TNB brand — what does Trexon offer to balance that?+
Trexon is privately held and founder-led — Chandra Rau (MIT alumnus) is reachable directly at +60 12-770 7249. If quick decisions, transparent pricing, and a 60-second proposal matter more to you than a utility brand, Trexon is built for that. Both vendors use Tier-1 panels and SEDA-registered installation.
Does GSPARX bundle EV chargers like Trexon?+
EV chargers are not bundled in GSPARX's solar checkout on its public site as of May 2026. Trexon bundles Wallbox, Tesla, Autel, ABB, and Schneider chargers into the same order.
Switching from a GSPARX quote to Trexon — how does it work?+
If you have not signed GSPARX's contract, just compare proposals. If you've already signed a lease/PPA, the cancellation terms in that agreement apply — read them carefully or ask GSPARX for clarification. Trexon will not encourage you to break a signed agreement.
Is owning a solar system better than leasing from GSPARX?+
It depends on your tax position and cash flow. Outright ownership (Trexon) typically delivers lower lifetime cost and full ownership of NEM export credits; leasing (GSPARX) shifts capex off your balance sheet at the cost of higher long-term spend. Run both numbers — Trexon's calculator at /calculator handles the comparison.
