New 700 Watts Solar Panel Introduced by Longi

Longi, one of the world’s top solar technology companies from China, has launched its latest high-performance 700-watt solar panel at the SNEC 2025 Solar Exhibition in Shanghai. This new model is part of a major leap forward in solar innovation.

Key Specifications

Power Output: Produces more than 700W, making it one of the most powerful standard-sized panels in the market.
Panel Size: Measures 2,382 mm × 1,134 mm, which is compact yet highly efficient.
Module Efficiency: Almost achieves 26% efficiency, nearing towards the industry record.
Cell Efficiency: Longi’s new solar cells, based on HIBC technology, have reached an outstanding 27.81% efficiency.
Power Density: Delivers up to 259W per square meter, a new benchmark in the solar industry.
Heat Performance: Comes with a temperature coefficient of –0.24%/°C, ensuring better performance during hot weather.

Technology Behind the Panel

HIBC Technology
The panel uses Hybrid Interdigitated Back Contact (HIBC) cells that combine multiple advanced technologies, including those used in HJT and BC cells. This helps in boosting efficiency and power generation.
Smaller Size, More Power
Despite being smaller than other 700W panels, Longi’s version produces more power thanks to better engineering and design.
New “Power Density” Standard
Longi has introduced the concept of “Power Density” to highlight how much power can be produced per square meter, which is especially important for rooftops or limited-space installations.

Impact on the Solar Industry

Efficiency Revolution: This panel pushes the solar industry further into the 25%+ efficiency era, beyond older technologies like PERC and TOPCon.
Ready for Market: It’s not just a lab experiment—Longi is ready to start mass production and sales.
Global Reach: Longi already supplies solar equipment to projects in over 85 countries across 6 continents.

Longi’s Chairman, Zhong Baoshen, said the new panel marks “another peak in technological innovation.” He emphasized that higher efficiency on regular-sized panels means more energy and better long-term value for users.

Why This Is Important

Better Energy Output: More electricity can be generated from the same roof or land space.
Innovation Leadership: Keeps Longi ahead in the global solar market.
Green Energy Growth: Contributes to cleaner, low-carbon energy solutions for the world.

These 700W solar panels will soon be available in global markets, making it easier for homes, businesses, and power stations to adopt high-efficiency solar systems and reduce energy costs.

In summary, Longi’s new 700W HIBC solar panel is a breakthrough in solar technology, offering unmatched efficiency, smart design, and readiness for real-world use—all helping move the world faster toward clean energy.
