Do solar panels eventually stop producing any power?
I have some second hand panels that are around 10 years old, I'm sure they are less efficient and I have had to replace diodes etc - but it seems to me that if you have lots of space (as we do in Aus) you could just keep adding new panels without getting rid of old ones
- fyfy18 6y agoSolar panels you buy today just go down in efficiency - if you are installing them on say a house, they will continue producing good power output for the lifetime of the house (bar physical damage). Typically they will come with a waranty that after 25 years, they produce at least 80% of their rated output. (You will probably need to replace the inverter during that time, but the panels will be fine)
- WrtCdEvrydy 6y agoWould it be viable to create a business to take the old panels and basically just mount them out in the desert to provide nearly free power (assuming you just do morning loads)?
- ZeroGravitas 6y agoThe progress of PV technology over 3 decades means it's probably cheaper to recycle them for raw material and build out new PV.
