As solar energy becomes more popular in Singapore, many homeowners are installing rooftop panels to cut electricity bills and reduce carbon footprints. But did you know that without a proper inspection and submission, your solar system could be unsafe — or even illegal?
Here’s what we uncovered at a recent project in Jurong West, and why a Licensed Electrical Worker (LEW) inspection is a must.
⚠️ The Problem: Unverified and Unsafe Solar Installation
The homeowner had recently installed solar panels through a contractor, but noticed:
- The inverter kept fluctuating
- The solar meter wasn’t showing export readings
- The contractor did not provide any SP submission or LEW sign-off
We inspected the system and found:
- No surge protection device (SPD) on the AC side
- DC isolators not wired correctly
- Earthing resistance above acceptable limits
- No single-line drawing or labelling
This setup was not only non-compliant with EMA regulations, but also posed a fire risk.
✅ Our Solution
Competent Electrician Pte Ltd dispatched a Licensed Electrical Worker to carry out:
- A full electrical health check on the solar system
- Correction of isolator wiring and breaker sizing
- Installation of SPD and proper labelling
- Testing of inverter output and performance
- Submission to SP Group and EMA with updated documentation
The homeowner now enjoys peace of mind, knowing their solar system is compliant and safe.
🤔 FAQs from Solar Homeowners
Q1: My solar panels seem to work fine. Do I still need an inspection?
Yes. You may still be non-compliant without knowing it. If there's a fault or fire, insurance may not cover damage if your system lacks LEW approval.
Q2: What if my installer didn’t give me any documentation?
This is a red flag. Contact us to conduct a compliance audit and submit necessary approvals on your behalf.
Q3: Do I get SP rebates without submission?
No. You must submit through a LEW to qualify for grid-tie metering and any rebate program.
