Public facilities


on your page [ website,_1959 ] the following is written.

"Public Facilities

In the early 1960s NEC Corporation was the leading manufacturer in the area of PV-cells in Japan. In fact, as of 1961 NEC’s PV-cells had been installed in all of 6 wireless relay stations and 8 lighthouses in Japan."

Due you have any source available, that confirms both facts?
