Interesting old panel. Solar Power Corporation G 261 (Exxon)

SolaRevolutionSolaRevolution Solar Expert Posts: 407 ✭✭✭✭✭✭
Solar Power Corporation, Woburn Massachusetts.
"Solar Power Generator" Model NO. G 261
4 volt, hand soldered, two strings of 13 cells.

I was unable to find a power rating.
A search on line told me this company was a subsidiary of Exxon back in 1975.

I was doing a system upgrade for a guy here in Mendocino County, CA. He had me change out a Trace DR system for an SW. (Replace a 17 year old inverter for a 13 year old one.) We got to talking about old equipment and he mentioned some old panels he has in the shed. He seems to think he bought them used around '82-'83. He originally had three (for 12volts) but one burned out years ago. This and its mate have been put away ever since.

Anyone know anything else about them?

    Hi 
    Just a note of possible interest.
    The above two photos show a PV array that has been in use on my property for an estimated 40 years, initially as a power supply for a radio comms unit on a Fire Tower used by the County Fire Authority. However with advances in Fire Detection Systems the Fire Tower was made redundant and removed Approx. 20 years ago. Since then we have been using the panels to drive 2 Electric Fence Units for stock control. We are located in Mirboo North, South Gippsland, Victoria, Australia.
    Came across this site when researching Solar Power Corporation and thought that it may be of some interest to some of your members
    They obviously made a good Solar panel, as these panels have been sitting in the Australian Hail,Rain,Snow and 44 deg c for 40 years.
    Regards

    OracleBob!, Thanks for taking the time to make and post these cool photos.  Funny, it seems they pretty much "got it right" when it came to making solar panels all those decades ago. Great to see these panels still in service. They look to be in great condition, still.
