Building Solar Systems That Stand the Test of Weather
In Singapore, rain is as common as sunshine. But for some solar owners, those sudden downpours can bring more than just cooler air, they can sometimes cause system shutdowns or electrical trips.
At Sunollo, safety isn’t an afterthought. It’s the foundation of reliable solar energy. Every system we build is designed and tested to stay safe and stable through rain, humidity, and everything our tropical climate can throw at it.
How Sunollo Meets and Exceeds Safety Standards
Solar installations in Singapore operate under strict guidelines from the Energy Market Authority (EMA) and SP Group, and for good reason. These regulations make sure every solar system connected to the grid is both electrically safe and operationally sound.
At Sunollo, our engineers follow the SS-638 Code of Practice for Electrical Installations. These standards cover everything from grounding and insulation resistance to protective devices like RCDs (Residual Current Devices). They define how systems must handle faults, moisture, and power fluctuations, the exact issues that can cause tripping during wet weather.
By following these standards closely, we make sure every system we deliver is not just efficient, but also safe and built to last.
Designed for the Tropics, Built for Longevity
Singapore’s humidity can quietly wear down electrical systems over time. Moisture is the silent enemy of insulation, so Sunollo uses only IEC-certified components and IP65/IP67-rated connectors that can withstand heavy rain and high humidity.
From how we route cables to how we seal junctions, every detail is engineered to keep water out and minimise leakage currents. Our approach combines international best practices with local weather insights, ensuring our systems stay resilient year after year.
Testing Every Connection Before the Sun Comes Up
Before we commission any system, we run a full insulation and leakage current test. This simulates wet-weather conditions to make sure every wire, seal, and connector holds up under Singapore’s climate.
If we detect even a minor risk, we fix it before handover. We don’t power up until everything checks out.
Why Safety Matters for You
All these behind-the-scenes steps add up to something simple: peace of mind.
When your system keeps running smoothly through a thunderstorm, that’s the result of good engineering and proactive maintenance. It’s why Sunollo customers experience fewer nuisance trips, longer component lifespans, and higher energy uptime.
Our systems don’t just meet the rules, but they go beyond compliance to deliver performance that’s steady, safe, and stress-free.
Beyond Compliance: Sunollo’s Commitment to Care
At Sunollo, regulations are just the starting point. Every installation is a promise: we’ll build with precision, test with care, and maintain with consistency.
Reliability isn’t about avoiding problems; it’s about designing systems that stay dependable no matter what the weather brings.
That’s how we keep your solar power shining, rain or shine.
