Breaking Barriers in Renewable Energy: Eneco Partners with GoodWe to Launch Suncake Series

Overcoming the Barriers in Renewable Energy Adoption



Eneco Co., Ltd., located in Shibuya, Tokyo, is set to revolutionize Japan's renewable energy market by partnering with GoodWe, a leading inverter manufacturer globally. This partnership aims to facilitate the widespread adoption of solar power and battery storage systems in the Japanese market, offering consumers high-performance energy solutions.

The Background of Collaboration: Addressing Structural Losses in the Japanese Market


In recent years, Japan has seen a surge in demand for solar power and battery storage, driven by rising electricity prices and increased awareness of disaster preparedness. However, several challenges have made it difficult for consumers to make optimal choices:

  • - Rising Middle Distribution Costs: Increasing prices due to a multi-layered wholesale structure.
  • - Lack of Clarity in Manufacturer Selection: Difficulty in accessing world-class high-performance products.
  • - Variability in Quality of Installation: Insufficient after-sales support post-installation.

To tackle these challenges, Eneco plans to align directly with a globally recognized manufacturer while leveraging its strengths in design, installation, and subsidy applications to redefine the standard for renewable energy penetration in Japan.

About GoodWe


GoodWe stands among the top ten inverter manufacturers in the world, boasting an impressive reputation particularly in the hybrid systems combining solar power and battery storage. With products distributed in over 100 countries, they are highly regarded in the European and Asian markets for their combination of technical expertise and excellent cost performance.

Highlight: Up to 50,000 JPY/kW Subsidy for Suncake Series!


A significant aspect of this partnership is the introduction of GoodWe’s latest solar panel series, Suncake. This series has been recognized under Tokyo’s Cool Net initiative, offering additional subsidies during the designated period from April 2023 to March 2024 to enhance household solar installations.

Distinct Features and Subsidy Advantages of Suncake Series


  • - Suncake 240W Model: With a compact size and anti-glare specification, this model qualifies for a substantial subsidy of +50,000 JPY/kW.
  • - Suncake 440W Model: Recognized for its anti-glare feature, this model secures an additional subsidy of +20,000 JPY/kW.
  • - Ideal for Residential Areas: Weighing approximately 8kg/m², these ultra-light panels minimize the load on roofs. Its all-black design prevents light pollution, enhancing aesthetics and preventing neighborhood glare issues.
  • - Long-term Assurance: Offering a 12-year product warranty and a 30-year output guarantee assures peace of mind for homeowners.

Offering Value Through a Unique Model


Despite having excellent products and generous subsidy frameworks, without a reliable system for applications and quality installations, customers cannot fully benefit. Eneco provides a one-stop solution, ensuring accurate subsidy applications through a dedicated administrative team and delivering high-quality installation via a vast network of skilled artisans in the Kanto region.

Comments from President Yuma Sawada


Yuma Sawada emphasizes that “the best products aren’t necessarily expensive; rather, what is essential is that fair products are accessible at reasonable prices.” He points out that while remarkable products exist globally, the structural constraints in Japan have often limited access to these options. The collaboration with GoodWe, coupled with the Suncake series, represents significant progress in addressing these structural issues. “With our mission of sharing the power of the sun and bridging traditions with the future, we intend to enhance lifestyle value through energy.”

Future Outlook


Looking ahead, Eneco plans to accelerate its expansion nationally, enhance its partnership network, and broaden its service offerings. The focus will extend beyond solar energy and batteries to comprehensive solutions in real estate and remodeling to support the overall value enhancement of residences.

A New Mission: Transmitting Tradition into the Future through Solar Power


Eneco aims to reinvent living spaces through “Energy x Inspiration x Connection,” targeting an upgrade for one million households. Their mission goes beyond mere sales of equipment; it is about harnessing solar energy and technology, coupled with creative ideas and the essence of connection (“Wa”), transforming the concept of housing and living into something more sustainable and liberated.
