JinkoSolar has unveiled the Tiger Neo 5.0 residential solar module, which utilizes new TAC technology to achieve 25.52% module efficiency. The announcement was made during the company’s Global Tech Day in Shanghai.
Why it matters
The release aims to enhance residential solar performance through an improved cell architecture that increases power output while reducing shading. Simultaneously, the company is scaling its energy storage footprint with a new 220MWh project in Germany.
The Tiger Neo 5.0 module reaches a maximum power of 510 W, while the Tera storage unit offers 5.01MWh of capacity with a 20-year design life. Peak cell efficiency for the new architecture is rated at 28%.
The players
JinkoSolar
JinkoSolar is a global solar module manufacturer that focuses on producing high-efficiency photovoltaic products for international markets.
Jinko ESS
Jinko ESS is the energy storage division of JinkoSolar that develops and deploys large-scale battery systems and power management solutions.
The details
The TAC technology employs a 2 plus 1 cell architecture by applying heterojunction passivation to the p-type emitter and tunnel oxide passivated contacts to the n-type region. This configuration removes front-side metallisation to minimize optical shading and supports a power temperature coefficient of -0.24% per degree Celsius.
Timeline
JinkoSolar held its Global Tech Day in Shanghai on October 20, 2026.
The Big Picture
The introduction of the Tiger Neo 5.0 module represents a technological iteration building on the 700 GW of total TOPCon based installations worldwide. This shift signals a transition toward more efficient cell architectures that replace older, less effective metallisation methods.
The transition to 25.52% module efficiency allows for higher power generation in smaller residential rooftop footprints. Enhanced storage units like the Tera system provide homeowners and grid operators with more reliable capacity and longer design lives for energy management.
The takeaway
This launch highlights the industry trend toward increasing energy density in residential solar hardware. Readers can look for these advanced modules to potentially lower the long-term cost of residential power generation as supply chains adopt the new architecture.
