About 1Solar
At 1Solar, we believe that every suitable rooftop in Singapore can become a long-term, energy-producing asset – if designed and engineered correctly from the start.
We are not a marketing company selling panels. We are an engineering-led team focused on system performance, installation quality, regulatory compliance, and long-term return on investment.
We design and install solar systems for commercial buildings, industrial properties, and landed homes across Singapore.
Our systems are engineered specifically for Singapore’s tropical climate - heat, humidity, heavy rain, and long operating hours. Every project undergoes site-specific structural, electrical, and regulatory assessment before installation to ensure safety, compliance, and long-term performance.
We design systems based on real-world energy usage and financial outcomes. Every proposal includes transparent ROI projections, realistic yield estimates, and conservative payback timelines - built for long-term returns, not short-term promises.
We focus on fewer projects to maintain engineering discipline and installation quality. Each system is customised, inspected, and optimised to deliver consistent performance over decades - not rushed for volume.
We believe clarity builds trust. From proposal to commissioning, you’ll know exactly what’s being installed, how it performs, what’s guaranteed, and how your system is maintained over time.
To make solar adoption in Singapore simple, reliable, and financially sound – through precision engineering, honest advice, and long-term system performance.
We design and install solar systems properly – or we don’t do them at all. From consultation to commissioning and long-term monitoring, every decision is backed by data, engineering standards, and clear accountability – not marketing claims.
I assumed solar installation would turn my house into a construction site. 1Solar’s team proved me wrong. They handled everything — from roof inspection to electrical setup — without disrupting our daily routine. They even coordinated SP PowerNet’s approval for us. I barely noticed the work until I saw my next utility bill drop by 65%.
1Solar gave realistic projections, not inflated promises. Our system hit breakeven just after 4 years — almost exactly as they projected. The transparency in their numbers gave us real confidence.
We were hesitant at first about roof leaks. 1Solar’s engineers explained how they waterproof mounting points and even showed post-install inspection footage. Two years in, zero leaks - and perfect system output. It’s clear they care about doing it right, not just getting it done.
We didn’t go solar to ‘save the planet’ — we did it to reduce long-term costs. But over time, seeing how much cleaner our energy footprint became made us proud. It’s satisfying knowing our home now produces more power than it consumes most days.
