Solar panels for Dummies.

[mouthpiece]

I dont know the timeline but Solar panels have become WAY more efficient in recent years...over like the last 10 years I think. panels are smaller and generate alot more energy in that smaller package.
But for a barn or cabin, I agree. I would not use a 20 year old panel setup on my house.
But I still wouldn't ever buy them because the price makes the ROI longer than I'll be alive.

I agree with this but they can still put out some watts!

If you think they are obsolete but brand new that would be perfect for someone like me that wants them for a barn or cabin. They should still work 100%. So i disagree somewhat.
