Japan Solar PV Inverter Market Size, Share, Trends and Forecast by Technology, Voltage, Application, and Region, 2026-2034

Description

The Japan solar PV inverter market size reached USD 534.4 Million in 2025 . Looking forward, IMARC Group expects the market to reach USD 761.9 Million by 2034, exhibiting a growth rate (CAGR) of 4.02% during 2026-2034 . The market is driven by increasing renewable energy (RE) targets, stringent government incentives, expanding grid modernization, rising electricity demand, continuous technological advancements, declining inverter costs, and growing adoption of distributed energy systems across residential and commercial sectors.

JAPAN SOLAR PV INVERTER MARKET TRENDS:

Shift Toward Distributed Solar Installations

A rising shift from large-scale, centralized solar installations to distributed solar systems, particularly evident in the residential and commercial sectors is driving the Japan solar PV inverter market growth. According to 2024 reports, over 3 million residential solar systems were installed in Japan in the past year, reflecting a strong shift towards decentralized energy generation in the residential sector. This transition is driven by factors such as limited land availability for expansive solar farms and the decreasing costs of solar photovoltaic (PV) technology, making small-scale installations more accessible. Besides this, government incentives, including feed-in tariffs and subsidies, are encouraging homeowners and businesses to adopt rooftop solar panels. This trend significantly influences the solar PV inverter market, as there is an increased demand for string and microinverters suitable for decentralized energy systems. Additionally, these inverters are essential for optimizing the performance and efficiency of smaller-scale solar installations, thereby supporting the broader RE objectives of the region and impelling the market demand.

Emphasis on Energy Storage Integration

The integration of energy storage solutions with solar PV systems is boosting the Japan solar PV inverter market share, aiming to address the intermittency of solar power and enhance grid stability. This advancement is crucial for Japan because it supports the country's efforts to lower greenhouse gas (GHG) releases while expanding the RE utilization. In confluence with this, the government has initiated energy storage promotion programs that have improved the viability of solar-plus-storage systems through continuous technological advancements in battery development. For example, in April 2025, Sungrow announced that its residential energy storage system, including the SH5.5RS-JP hybrid inverter and a battery with up to 12.8 kWh capacity, obtained JET certification. This certification ensures compliance with Japanese safety and environmental standards, facilitating the adoption of integrated solar-plus-storage solutions in residential settings. Moreover, due to the rising demand, the market requires advanced solar inverters to control energy transitions between solar panels, storage batteries, and the power grid. Furthermore, the hybrid inverter system maintains a vital position in energy management systems because it enables optimized energy consumption. It further provides standby power, enabling demand response features for enhanced sustainable power grid performance, which is significantly enhancing the Japan solar PV inverter market outlook.
