Independent advice for Singapore solar — separate from the installer. We assess your roof, model SP Group import/export under your actual tariff, and connect you to a vetted BCA-registered installer.
From SGD 600 standalone · SGD 2,500 full Solar Concierge
SG solar is growing fast but installer-led sales hide complexity. An independent consultant pays for itself in avoided mistakes.
SG solar installers mark up equipment 20–40% and rarely disclose shade loss, structural load limits, or degradation curves. Our assessment is paid by you, not the installer — so our advice is yours alone.
HDB requires written approval before installation. Failure to obtain it voids your lease conditions. We walk you through the SP Group Enhanced Central Electrical System (ECES) requirements and HDB panel size limits.
A compliant SG solar install touches four regulatory bodies. BCA structural sign-off, EMA grid-tie approval, SCDF fire-safety clearance, and NEA noise limits for inverters near residential boundaries. We check all four before the tender goes out.
Your export rate under SP Group Enhanced Feed-In Tariff (REFIT) or retailer Power Purchase Agreements varies by 30–50%. We model your actual bill across grid import, solar offset, and export revenue — not a generic payback calculator.
Engage one step at a time, or take the full Solar Concierge package at a fixed fee.
Drone + structural review
We commission a drone survey and coordinate with a licensed PE for structural load review of your roof. Outputs: shade analysis, available kWp, roof condition report, and structural suitability letter.
SP Group tariffs, OEM retailers, GST, BCA SES rebate
We build a 25-year cash-flow model using your actual SP Group monthly bills, your OEM retailer tariff (if applicable), GST impact, and the BCA Solar Energy Support (SES) rebate where eligible.
We issue RFQ to 3 vetted BCA-registered installers
We write the technical specification, issue the RFQ to three vetted BCA-registered installers, evaluate their submissions on a like-for-like basis, and deliver a scored recommendation memo.
At handover — before you sign off
On installation completion day, our inspector verifies panel orientation, string configuration, inverter placement (NEA noise-compliant), earthing, and inverter commissioning data against the contracted specification.
All four steps from site assessment through installer tender management to independent handover inspection — one fixed fee, one point of contact.

Trexon Energy is registered as a Malaysian consultancy. We serve Singapore clients remotely and via site visits for site assessment engagements. All installer partners we refer are BCA-registered and carry valid EMA grid-tie accreditation. We do not install solar in Singapore — we are strictly advisory. Our fee comes entirely from you, never from the installer, ensuring your interest is the only one we represent.
