2001 | 3-unit system with hydrogen storage begins operation. |
2003 | New 2-unit system with an original Honda electrolyser and a new solar array utilizing prototype Honda CIGS solar cells offers improved system efficiency. |
2008 | Solar array fitted with mass production CIGS cells from Honda Soltec Co., reducing the size of the array by 20% and further improving photo voltaic (PV) energy efficiency. |
2010 | New single-unit station begins operation, improving to world’s best system efficiency – increasing the efficiency by more than 25% (value calculated based on simulations) compared to the previous solar hydrogen station system, for a world’s highest system efficiency. |
