Why independent advice matters in Singapore
SG solar is growing fast but installer-led sales hide complexity. An independent consultant can help you spot those issues early.
Unverified installer quotes — we give you independent technical opinion
SG solar installers add their own margin to equipment 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 approval process is opaque — we know the rules
HDB requires written approval before installation. Failure to obtain it voids your lease conditions. We walk you through the SP Group electrical connection requirements and HDB panel size limits.
BCA + EMA + SCDF + NEA permits — most quotes skip them
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.
SP Group net settlement vs Open Electricity Market differs by retailer
Your export rate under SP Group's export arrangements or retailer Power Purchase Agreements varies by retailer. We model your actual bill across grid import, solar offset, and export revenue — not a generic payback calculator.
What we deliver
Engage one step at a time, or take the full Solar Concierge package at a fixed fee.
Step 1 — Site Assessment
StandaloneDrone + structural review
We commission a drone survey and work with a third-party registered Professional Engineer for a structural load review of your roof. Outputs: shade analysis, available kWp, roof condition report, and structural suitability letter.
Step 2 — ROI Modelling
StandaloneSP Group tariffs, OEM retailers, GST, applicable solar rebates
We build a 25-year cash-flow model using your actual SP Group monthly bills, your OEM retailer tariff (if applicable), GST impact, and any applicable Singapore solar rebate where eligible.
Step 3 — Tender Management
StandaloneWe 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.
Step 4 — Independent Inspection
StandaloneAt 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.
