Sunollo's founders — Kapil Seth and Nathalie Risteau — have been featured in The Straits Times, pv magazine, Mediacorp 8world News, French Tech Singapore, and the Singapore Green Building Council. They have spoken at the Asia Clean Energy Summit (ACES), ADB Clean Energy Forum, FIND Global Summit, and French Chamber of Commerce events. Before founding Sunollo, they jointly led a renewable energy joint venture with ENGIE that delivered electricity to nearly 50,000 consumers across Myanmar.
Most solar companies in Singapore have a brochure website and a phone number. That tells you almost nothing about who is actually running the company — what they have built before, what they believe, and whether they will still be around in 25 years when your warranty matters.
This page is different. It is a living archive of every talk our founders have given, every article they have been quoted in, every partnership we have announced, and every thesis we have published. If you are researching solar companies, this is the page that should make the decision easy.
The Founders
Kapil Seth — Co-Founder
Kapil is a renewable energy entrepreneur whose career spans power generation, green steel decarbonisation, and carbon solutions across Asia. He is VP of Renewables & Sustainability at Meranti Green Steel and has served as Chairman & CEO of Mandalay Yoma Energy, a joint venture with ENGIE that became Myanmar's largest decentralised solar energy company. He has been a speaker at the Asia Clean Energy Summit (ACES), the FIND Global Summit, the ESG & Sustainability Strategy Asia Summit, and the Global Solar Expo. Before renewable energy, Kapil built his career in strategy, finance, and large-scale operations. He co-founded Sunollo with one conviction: solar should be accessible to every household, not just the wealthy.
Nathalie Risteau — Co-Founder & CEO
Nathalie brings 16+ years of leadership across renewable energy, aerospace, and international business. She previously headed Airbus Helicopters' business for Myanmar, Cambodia, and Laos before founding Mandalay Yoma Energy, where she led the ENGIE joint venture that electrified nearly 50,000 consumers via solar mini-grids and commercial rooftop installations across Southeast Asia. She is a Director at Sol Partners, a consultancy driving renewable energy transition across the region. Nathalie has spoken at the ADB Clean Energy Forum, the French Chamber of Commerce in Singapore, and has been featured by the Singapore Green Building Council. She is a member of YPO, has served on the boards of EuroCham Myanmar and the International French School in Singapore, and holds a Master's in Strategy & International Business from Aston University (UK). She is fluent in English, French, and Russian.

Thought Leadership
22. "Sunollo — Age of Electricity" (LinkedIn Newsletter)
A weekly dispatch covering how power systems across ASEAN are evolving under electrification. Topics include hybrid procurement, storage-as-infrastructure, the energy trilemma (security, affordability, sustainability), and why residential solar is strategic infrastructure rather than a commodity purchase.
23. "Singapore Energy Security with Solar + Batteries" (Sunollo Blog, 2026)
An in-depth analysis of how Singapore's dependence on LNG through the Strait of Hormuz creates a structural vulnerability — and why solar + battery storage at the household level is not just a green choice, but a national security imperative.
24. "Shaping a Brighter Future: Solar Rooftops for a Sustainable Singapore" (LinkedIn Article)
A long-form piece on Singapore's residential solar potential, assessment of 100k+ rooftops, and how financing models can make solar accessible to every landed homeowner.
25. "Unlocking 100k Rooftops in Singapore with AI-Powered Solar Analysis"
How Sunollo is using AI and satellite imagery to assess every rooftop in Singapore for solar potential — turning data into action at scale.
The Thesis
Most people think solar is an environmental decision. It is not. It is an infrastructure decision.
Singapore imports 95% of its energy. That energy travels through some of the most geopolitically fragile chokepoints on Earth — the Strait of Hormuz, the Strait of Malacca. Every time tensions rise in the Middle East or South China Sea, Singapore's electricity prices move.
A solar system on your roof does not care about geopolitics. It generates electricity from a fusion reactor 150 million kilometres away, which has a proven track record of 4.6 billion years of uptime. Add a battery, and your home becomes its own power station — generating, storing, and consuming energy without depending on a single imported molecule of gas.
That is not an environmental statement. It is a strategic one.
This is what Sunollo is building. Not a solar company. A home power infrastructure company. Led by founders who have electrified 50,000 consumers in Myanmar, spoken at the ADB and ACES, collaborated with ENGIE and Porsche, and been quoted in The Straits Times and pv magazine.
The question is not whether to go solar. The question is who you trust to build your energy independence.
