We’re all thinking about it. How do these both compare against the high end solar panels then?
Truthfully, the only areas I say the both fall short on are efficiency and warranty (because Sunpower rules this).
However, here is something that may keep you up at night… SunPower, LG and QCell are around 2-3% more efficient. However they cost about 40-50% more…
For the sake of 2-3% more conversion efficiency, are they worth the extra cost? I’ll let you decide but I think you can guess my answer.
In fact, Jinko actually beats LG on its product warranty, with an extra 3 years again. SunPower laughs at them all though, with a 25 year product warranty.
In terms of performance warranties they are all averaging around 25-30 years. Both Canadian and Jinko have come a very long way in the past 5 years.
Also, as shown by them breaking previous world records, Jinko and Canadians are using advanced technology to make their panels more efficient. It may be soon that they are able to create similar panel efficiency and performance for a budget price.
