SINGAPORE, May 7, 2025 — Arysun, a climate-tech startup focused on democratizing solar energy adoption, has raised US$575,000 in pre-Seed funding, led by Wavemaker Impact, with additional participation from the First Move Fund. The funding will fast-track Arysun’s efforts to provide affordable, user-friendly solar solutions for middle-income households across Southeast Asia.
With rising energy costs, increasing climate awareness, and falling hardware prices, Arysun is positioning itself at the forefront of a regional transition to renewable energy. The startup aims to solve the accessibility gap for middle-class homeowners by providing an affordable line of solar solutions.
“We believe solar should be for everyone — and the key is sizing the right solution for our target customer to keep prices low. Every green electron generated must not be wasted. Anything that is over-speced adds a barrier to adoption,” said Ng Aik-Phong, Founder and CEO of Arysun. “With this funding, we’re building an affordable, smarter and scalable way to bring clean energy to millions of Southeast Asians in a way that makes financial sense for the middle income households and at the same time, enable us to achieve our long term environmental impact of 100 million tons carbon abatement annually.”
Enabling Every Middle-Class Household to Access Solar Energy
Powered by a rapidly expanding middle class, Southeast Asia is one of the fastest-growing regions globally—both economically and demographically—and is projected to become the world’s fourth-largest economy. In Indonesia alone, the number of middle-class households is expected to grow from 32 million to 54 million by 2035.
This demographic shift is driving a surge in energy needs, with residential electricity demand across the region projected to double from 2017 levels by 2040. According to the 8th ASEAN Energy Outlook, solar power’s share of installed capacity in ASEAN is set to rise from 7.7% (25 GW) in 2022 to approximately 27% (200 GW) by 2040—an eightfold increase.
Against this backdrop, Arysun is committed to designing hyper-local, tech-enabled deployment models that make solar adoption easier, more accessible, and more meaningful for middle-class households. By addressing everyday concerns and unlocking the value that matters most to families, we aim to accelerate Southeast Asia’s transition to a cleaner, smarter energy future.
Early adopters of Arysun’s solar starter-kits in Indonesia have reported electricity bill savings of over 50%, marking an important inflection point where the rapidly declining cost of Solar is starting to make not just financial sense, but bring about genuine excitement to Arysun’s target segment of customers. In Indonesia, electricity tariffs currently average around Rp 1,600 per kWh (approximately US$0.11), and residential energy costs for non-subsidized customers have risen by approximately 5% since mid-2022. For middle-income households, electricity expenses can account for 10% of monthly household income — an increasing burden as utility costs may continue to rise.
“As panel prices continue to fall, rooftop solar is fast becoming one of the highest value-returning assets for Southeast Asia middle-class families, with the potential to increase monthly savings by 15% to 20%,” said Guillem Segarra, Principal at Wavemaker Impact. “With a growing demand for cheaper energy alternatives, Aryun’s fit-for-need line of solar products that sits at the mass-market price point is well-positioned to service this huge yet under-served segment. We’re excited to back AP in his mission to create a consumer company that provides renewable and energy-efficient products designed for the everyday man on the street.”
What’s Next for Arysun
The pre-Seed funding will allow Arysun to expand its founding team, accelerate solar installations in Indonesia, which is the company’s primary target market, and build partnerships with local financing institutions, installers, and suppliers. In the mid-term, Arysun will also develop and pilot a digital solar adoption platform.
