30+ Year Old Solar Panel Is Still At Factory Specs! From 1979!

For those of you who are wondering how long Solar Panels will last out in the sun....

"To mark the 30th anniversary of my first PV module, I decided to climb up on my roof and bring it down for testing. "

"The module was designed to charge a 12-volt battery at a maximum voltage of about 16 VDC. When new, the 33-watt module produced 2.0 amps in full sunlight."

"It easily powered up the light bulb; my Fluke multimeter showed that under a full load of 2.015 amps, the module’s voltage was an impressive 14.93 volts."

"Your module is still performing to factory specifications — or perhaps a little better. That’s very good."

"My old module shows no signs of browning, electrical corrosion, or water intrusion. It certainly looks as if it’s ready to perform for another decade or two."

“A PV cell is a rock that makes electricity,” said Davidson. “Unless something corrodes the electrical contacts, it will still keep working.”

Don't forget that if the warranty is only 30 years, that doesn't mean it will stop putting out power that day. It may be reduced, but if there are no flaws in the panel by that time it should give you power for many more years.
