01 Why Demand for Repowering Is Rising
GBP K.K.'s repowering solutions have surpassed 230MW of installed capacity, including the replacement of more than 300,000 obsolete solar panels across Japan.
Older solar power systems face growing risks in Japan: aging components, frequent inverter failures, and increasing exposure to hailstorms, typhoons, earthquakes, and copper theft. As many incentive contracts (e.g., FIT, PPA, or other local schemes) from the early 2010s expire, system owners are looking to modernize without fully rebuilding. GBP’s repowering service solves this with minimal disruption and maximum benefit.
With our all-in-one approach—from inspection and design to construction and recycling—we help solar plant owners recover faster, reduce costs, and maximize long-term returns.

- Junction Box Replacements: 20,000+ units shipped, with remote monitoring and salt resistance options.
- PCS Inverter Upgrades: Boost PR values with more efficient, modern components—transformer-ready.
- Aluminum Cable Solutions: Reduce theft and save up to 25% on costs, with all compatible terminals and tools.
- Utility-Scale Capabilities: Licensed for special construction; completed megasolar projects up to 35MW.
03 Strong Financial Impact for Owners
A standard 1MW repowering project with panel and PCS upgrades can increase energy output by over 40% and double the system’s internal rate of return (IRR)—from 5.2% to 10%. GBP delivers these results quickly through in-house services, ensuring minimal downtime and compliance with local standards.
| Before | After (Replacement + PCS) | |
|---|---|---|
| Module Capacity | 1.0MW (250W × 4,000) | 1.12MW (315W × 3,555) |
| Annual Output | 1,150MWh | 1,630MWh (+42%) |
| IRR (FCF) | 5.2% | 10% |
