Richten Energy Heads to VivaTech, Bringing Colored Solar PV Façade Solutions to the European Market

As global attention continues to focus on energy transition and net-zero buildings around Earth Day, Richten Energy Co., Ltd. has been selected for the first cohort of the TTA x VivaTech 2026 delegation. Through the Taiwan Tech Arena（TTA） platform, the company will travel to Paris, France, to engage with European corporations, investors, and the international innovation ecosystem, marking an important step in its global market expansion.

TTA announced the first cohort of selected teams on April 20, with the second cohort expected to be announced before May 25. Launched in 2018 by Taiwan’s National Science and Technology Council（NSTC）, TTA is one of Taiwan’s key platforms for helping startups expand internationally by connecting technology, talent, markets, and capital.

In recent years, Richten Energy has focused on the development of colored solar PV façade applications, integrating solar power generation, building façades, architectural design, low-glare requirements, and the retrofit needs of existing buildings into practical building energy solutions.

Compared with conventional solar deployment, which has largely relied on rooftops, façade-based solar applications offer a strong response to several urban challenges: limited rooftop space in high-density cities, increasing demand for the renovation of aging buildings, and new market opportunities driven by net-zero building policies. The core value is not only to increase the surface area available for power generation, but to transform building façades from cost-bearing exterior surfaces into energy assets that combine power generation, energy savings, architectural design, and ESG communication value.

The Materials Testing Laboratory of the Institute of Architecture and Building Research under the Ministry of the Interior has already established a demonstration site for colored solar PV façades, allowing public buildings to take the lead in real-world adoption and data collection. According to publicly available information from the Ministry of the Interior, the first-phase experimental installation of colored solar PV façades achieved a power-generation ratio of 73.6%. In 2026, the program is expected to continue expanding, with cumulative installed capacity projected to reach approximately 424 kW. Starting in August 2026, newly constructed, expanded, or renovated buildings with a floor area of 1,000 square meters or more will also be required by law to install solar PV capacity. 

Richten Energy said that gaining application experience through the demonstration site of the Institute of Architecture and Building Research represents an important milestone in the team’s transition from technology development to market adoption.

For emerging technologies, the company noted, the lack of real-world validation often makes it difficult to overcome market trust barriers. The demonstration environment provided by the Institute has helped the team gather key data related to power generation, low-glare design, and architectural integration. More importantly, it has allowed colored solar PV façades to move beyond proof of concept and become a solution that can be understood by policymakers, industry partners, and the market.

Richten Energy CEO Weili Hsueh said urban energy transition will not happen on rooftops alone. The next major opportunity lies in the vast amount of building façade space that has not yet been effectively used.

“What we want to do is not simply install solar panels on walls,” Hsueh said. “Our goal is to turn building façades into energy interfaces that cities can accept, policymakers can support, industries can replicate, and international markets can understand.”

Hsueh also noted that during the TTA selection process, the judges raised direct and highly relevant questions from the perspective of market and investment decision-making. These questions covered whether the business model was viable, whether the pathway to scale was clear, whether the company had the ability to enter international markets, and how its technology could move from demonstration projects to standardized deployment.

“The questions were direct, but they were also extremely valuable,” Hsueh said. “They forced us to re-examine our technology, field experience, and market strategy, and to integrate what was previously scattered into a clearer growth roadmap. For a startup, going through this kind of review before entering the international market is itself a form of acceleration.”

In addition to its upcoming participation in VivaTech in Paris, Richten Energy has recently engaged with international networks through Asia Innovation HubAIH） and related connections with the Nasdaq Entrepreneurial Center. These exchanges have covered topics such as U.S. market entry, capital strategy, IPO pathways, strategic partnerships, and ecosystem integration, further strengthening the company’s internationalization roadmap.

The AIH x Nasdaq Entrepreneurial Center program focuses on supporting Taiwanese innovators in areas including U.S. market entry, access to capital, IPO strategy, strategic partnerships, and ecosystem development.

Hsueh expressed special thanks to AIH CEO Shu-Min Chen and AIH Chairman Hsiao-Chang Chen, noting that AIH’s international network helped the team recalibrate its global expansion strategy before entering the European market.

“Through AIH’s international connections, we were able to rethink our path to global markets from the perspectives of the U.S. market, capital structure, corporate governance, and partnership strategy before heading to Europe,” Hsueh said. “This reminded us that internationalization is not just about taking a product overseas. It requires a complete design that brings together technology, business model, capital logic, and real-world deployment scenarios.”

Richten Energy said its next stage of development will build on the company’s Taiwan-based demonstration experience. Through TTA and VivaTech, the company aims to connect with the European market, while continuing to deepen its understanding of the U.S. market and capital perspective through AIH and other international innovation networks.

The company will continue promoting colored solar PV façade applications in public buildings, campuses, commercial buildings, retrofit projects, and high-density urban environments.

Hsueh said the international market represents a higher standard of validation. Being seen, he added, is not the finish line, but the beginning of a greater responsibility.

“If Taiwan wants to build real industrial competitiveness in net-zero buildings and urban energy transition, we cannot stop at technology development alone,” Hsueh said. “We must complete real-world validation, connect with policy frameworks, and build the ability to export solutions across markets. Richten Energy will continue to take each step carefully and steadily, so that Taiwan’s homegrown technology can be tested and recognized on a larger international stage.”
