From Standard Types
to Customized Off-Grid Solar Panels
We Provide One-Stop Solutions to Meet Your Needs
JUMAO NEW ENERGY, a wholly owned subsidiary of our company, is a well-established manufacturer with a long history in the solar panel industry since its founding in 2001. Our specialized team, composed of veteran engineers, has implemented a Japanese-style production management system, ensuring stable quality and flexible responsiveness.
In addition to researching and developing new products, we have a system in place to meet diverse needs—from standard type panels to customized products and even off-grid solutions—enabling us to provide one-stop support for all customer requirements.
Moreover, we streamline customer communication by centralizing the point of contact within our company, allowing for smooth and seamless coordination without the hassle of interdepartmental adjustments.
While many solar panel manufacturers worldwide are concentrated in China, some customers face communication challenges and concerns due to language and cultural differences between Japan and China. To address these issues, our experienced Japanese and Chinese staff collaborate closely to offer the most reassuring and smooth communication and support system for our customers.
By overcoming language and cultural barriers and maintaining a customer-centric approach, we strive to build a trustworthy partnership with our clients.
Our Strengths
Remanufacturing Discontinued
Solar Panels with the Same Dimensions
High-Quality Panels Compliant with IEC Standards
FIT Program Launched in July 2012: Then vs. Now
When the Feed-in Tariff (FIT) scheme began in July 2012, the mainstream solar panels at the time had an output of around 260W and standard dimensions of 1637mm × 952mm × 40mm.
More than a decade later, today’s mainstream panels are in the 550W class, with dimensions of 2279mm × 1134mm × 35mm, making the long side approximately 1.4 times longer than before.*¹
As the industry evolves and market demands shift toward higher output and larger panels, unforeseen challenges have arisen—such as the discontinuation of older panels or the withdrawal of manufacturers from the Japanese market.
One of the most common issues reported is the inability to obtain replacement panels in the original sizes, especially when repairs or replacements are needed due to natural disasters. Attempting to install newer, larger-sized panels can lead to incompatibility with existing mounting systems, often resulting in unexpected costs and added installation complexity.
To solve these issues, we have launched a line of “remake” solar panels that match the original dimensions exactly.
These panels are manufactured in compliance with IEC (International Electrotechnical Commission) standards, ensuring long-term safety and reliability.
Our remake panels offer an ideal solution for customers looking to minimize additional costs and maximize the use of their existing infrastructure. We invite you to consider our remake solar panels as a smart and efficient alternative.

The Ideal Model for Sawtooth Roofs with 500mm Spacing
High-Efficiency, Highly Compatible Solar Panels Developed in Response to On-Site Feedback
Rapid Expansion of Rooftop Solar Installations on Factories, Warehouses, and Commercial Facilities
In recent years, the adoption of solar power systems on rooftops of factories, warehouses, and commercial buildings has been rapidly accelerating. In response to this trend, we received a request from one of our corporate partners:
“We need solar panels that take full advantage of the characteristics of sawtooth (corrugated metal) roofs.”
Specifically, on-site professionals have shared the following needs:
●Improve design and installation efficiency
●Optimize costs by using four-point mounting brackets
●Maximize the effective use of available roof space
To meet these requirements, we have developed and now offer a dedicated solar module with output in the high 400W range, sized at 1906mm × 1134mm × 30mm.
This module is designed to perfectly fit sawtooth roofs with 500mm rib spacing, enabling both easier installation and reduced total costs. Additionally, its lightweight yet highly durable frame ensures long-term reliability and safety, even under extended use.
This solution is ideal for businesses seeking a balance between installation efficiency and cost performance.

Off-Grid Solar Panels
Entering an Era of Disaster Preparedness, Environmental Responsibility, and Energy Independence
Standalone Solar Panels for Public Infrastructure and Outdoor Use
Meeting the Needs of Disaster Preparedness, Sustainability, and Energy Independence
In recent years, growing environmental awareness and the increasing demand for reliable power during emergencies have drawn attention to off-grid solar power systems.
"Off-grid" refers to self-sufficient power systems that operate independently from the public electricity grid. These systems utilize off-grid solar panels, which are already being used in a wide range of applications, including:
●Lighting systems at road construction sites
●Solar-powered lights in parks and along streets
●Sensors installed in highway median strips
●Power supply for RVs, temporary housing, and remote mountain facilities
While the term "off-grid panel" may not be widely recognized, these systems are already integrated into many familiar devices and facilities in our everyday lives.
Our company offers small to mid-sized off-grid panels, available even in small-lot production. We also provide customization options for size, output, and specifications, tailored to your intended use and installation environment. In addition to domestic projects in Japan, we are also well-equipped to support international deployment.
