In Singapore’s push for sustainability, many commercial properties are now upgrading their solar energy systems. Whether you’re expanding panel capacity, replacing old inverters, or responding to audit flags — ensuring that your solar upgrade is safe, compliant, and efficient is essential.
⚡ Why Upgrade Your Commercial Solar System?
- Your current inverter is outdated or underperforming
- Your energy demand has increased (e.g. new equipment, EV chargers)
- You want to tap into SP rebates by connecting a grid-tied system
- You're expanding solar panels for better ROI
- You received a compliance notice or audit request from EMA/SP
🚨 Risks of Skipping Proper LEW Inspection
We’ve found several recurring issues in commercial solar systems:
- Improper cable sizing or termination
- No surge protection on AC/DC sides
- Unlabelled or outdated single-line drawings
- Overloaded DBs with shared loads
- Lack of SP Group submission
⚠️ These risks not only reduce efficiency but also pose serious safety and insurance issues.
🤔 Common Questions from Facility Managers
Q1: Do I need to replace my entire system to upgrade?
Not necessarily. We assess your existing system and advise if only components like the inverter, isolator, or DB need change.
Q2: Can any contractor do the upgrade?
No. Only a Licensed Electrical Worker (LEW) can legally submit changes to SP Group and sign off on the system.
Q3: What happens if I skip submission?
Your solar system may be considered illegal, ineligible for rebates, or flagged during building inspections.
