Solar panels typically range in cost between ¥150,000 and ¥250,000 per kilowatt (kW), so for an average home with a 4kW system, the total installation costs fall somewhere between ¥600,000 to ¥1,000,000. Solar panel costs often comprise 40-50% of total installation expenses in Japan.
To find out the reasons why solar PV system prices are expensive in Japan, this report examined two types of costs, PV module costs and construction costs, which are major factors of the price disparity. However, there remain issues that have not been thoroughly examined. These issues are indicated in the following.
Deployment of solar PV has accelerated in Japan as well, after the introduction of the Feed-in Tariff system (hereinafter referred to as FIT) in July 2012, and the cumulative installed capacity of solar PV has reached 23 GW by the end of 2014. System prices are declining rapidly, along with the wide deployment of solar PV as described above.
In Japan, the average daily energy yield for solar installations is approximately 4.07 kWh per kWp installed, resulting in an annual yield of around 1,485 kWh per kWp, reflecting efficient energy production under optimal conditions. 2 As of 2023, the price of electricity for households in Japan was approximately USD 0.20 per kWh.
In Germany, the figure dropped from $6.6/W in 2007 to $2.1/W in 2014, recording a decline of 68%. Meanwhile, the price of solar PV systems in Japan is said to be relatively high compared to global standards. According to IEA-PVPS (2015), the solar PV system price in Japan in 2014 was $3.5/W for residential solar PV and $2.5/W for ground-mounted PV.
Because, foreign module manufacturers could not sell their modules at higher prices (in USD) in the Japanese solar PV market under this circumstance. Next, we will examine modules produced by Japanese manufacturers.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%. Europe follows closely with 32% market share, where standardized container designs have cut installation timelines by 60% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 45% CAGR, with China's manufacturing scale reducing container prices by 18% annually. Emerging markets in Africa and Latin America are adopting mobile container solutions for rapid electrification, with typical payback periods of 3-5 years. Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh.
Technological advancements are dramatically improving solar storage container performance while reducing costs. Next-generation thermal management systems maintain optimal operating temperatures with 40% less energy consumption, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $80/kWh to $45/kWh since 2023. Smart integration features now allow multiple containers to operate as coordinated virtual power plants, increasing revenue potential by 25% through peak shaving and grid services. Safety innovations including multi-stage fire suppression and gas detection systems have reduced insurance premiums by 30% for container-based projects. New modular designs enable capacity expansion through simple container additions at just $210/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. Recent pricing trends show 20ft containers (1-2MWh) starting at $350,000 and 40ft containers (3-6MWh) from $650,000, with volume discounts available for large orders.
