Japan’s Tokyo Metropolitan Government has selected AIKO’s Nebular solar modules for the highest subsidy tier under the city’s 2024 High-Performance Solar Power Systems certification program. Eligible households that install these certified modules can receive a subsidy of up to JPY 80.000 ($0.56)/kW.
A leading name in the back contact (BC) solar technology, AIKO says its module stood out as the only product selected under the non-glass, anti-glare module category out of 193 certified solar products.
Other categories assessed include modules integrated into building materials, small solar cell modules for polygonal and building material types, and anti-glare solar modules with glass.
All of these modules were found to meet the standards for PV power generation systems with excellent functionality. The other incentive brackets are JPY 50.000/kW, JPY 20.000/kW, and JPY 10.000/kW.
Tokyo’s criteria for high-functionality PV systems include domestic market availability, a minimum 10-year product warranty, and certification under JET PVm (Japan Electrical Safety and Environment Technology Laboratories) or IEC61215/IEC61730 international standards.
Weighing 8.6 kg, which is around 60% lighter than conventional glass modules, AIKO says the Nebular series has a standard footprint of under 2㎡, ‘designed to meet the unique needs of Japan’s rooftop solar market.’ These panels offer up to 22.5% module efficiency and 450 W power output, along with offering enhanced crack resistance and superior thermal dissipation to work safely in high-temperature environments.
Their anti-glare feature makes them suitable for sensitive locations such as airports, highways, and densely built urban areas.
Recently, heterojunction (HJT) solar PV manufacturer Meyer Burger announced that it was the only company listed under category C, the highest funding bracket for the highest funding bracket in Italy’s Transizione 5.0 tax credit scheme, with up to 150% tax credits (see Meyer Burger’s Made in Europe Modules Qualify For Italian Incentives).
These announcements from 2 solar PV manufacturers with differentiated technologies point to the growing trend of governments incentivizing high-performance, next-generation modules that are high on efficiency.
AIKO’s Comet2U series of BC modules, with their 24.2% mass production module efficiency, has been leading the TaiyangNews TOP SOLAR MODULES Listing for many months now (see TOP SOLAR MODULES Listing—March 2025).
