GBP K.K. is a Japan-based solar company covering the full project lifecycle — design, construction, and O&M. Our core specialty is manufacturing precision-matched replacement panels for discontinued and legacy models that the market no longer supplies.

Japan's solar installations were among the first in the world to reach large-scale aging, and GBP built its expertise solving that problem — delivering over 500,000 compatible replacement panels to operators across the country.

That same solution is now available globally through GBP Direct, with panels already shipped to facilities in Australia, Europe, and North America. Where most suppliers have moved on to newer generations, we haven't. Keeping aging solar plants running is what we do.

All orders are sold on an FCA (Free Carrier) basis in Shanghai, Ningbo, or Guangzhou.

*FCA (Free Carrier) means the seller delivers the goods to the designated location, and the buyer arranges international shipping and export thereafter. If you are not familiar with FCA terms, please contact your freight forwarder before placing an order.
