Collective housing project in
Tochigi Prefecture, Japan
Tochigi Prefecture, Japan
The modules of this project are installed on all four sides of the rooftop of a residence in Nasu-Shiohara, Tochigi Prefecture, Japan, with an installed capacity of 54.5 kW. AIKO’s ABC modules provide a more reliable energy source for the residence to cope with the complex local weather conditions due to high altitude, low temperatures, and snowy winters.
Project results
According to measurements, for the same rooftop area, the power generation of AIKO’s N-type ABC modules is 7% higher than TOPCon and 15% higher than PERC. Moreover, AIKO’s ABC modules have a 30-year power warranty, which means longer life and more benefits.

Project challenge
The site is located on a highland with heavy snowfall in the winter, and accumulated snow on the rooftop can lead to decreased power generation.
The residence has four-sided sloping rooftops, and installing the modules on the shady rooftops can affect the amount of power generated.


Solution
The project utilizes the N-type ABC Neostar 1N modules from AIKO, with an installed capacity of 54.6 kW. With the world’s No. 1 commercial mass production efficiency, AIKO’s ABC modules effectively increase the power generation capacity for the same rooftop area, cope with the unfavorable power generation factors brought by the complex valley terrain and snow cover with its unique superior partial shading optimization function, and ensures stable and efficient power generation in special scenarios
