Everyone knows that Sunpower solar panels are one of the most efficient in the industry. Shortly following are LG solar panels offering a similar conversion efficiency.
For the Sunpower maxeon 3, they offer an incredible 22.6% efficiency.
For LG NeON 2 you’re looking at 21.1% or NeON R 22%.
So yes, Sunpower solar panels are more efficient than LG panels. Essentially on paper, this means that Sunpower panels will convert more sunlight into energy. This would mean that you would get energy for cheaper, and pay off your system faster.
How much does this really matter?
But… Does it really matter?
Considering the price difference then no… not really.
Because Sunpower actually costs more than LG, it means the pay off time would be pretty much the same. It actually cancels itself out.
Additionally, solar panel efficiency might not actually matter as much as you think. At the end of the day your system will be the same size.
E.g. A 6.6Kw system is always going to produce 6.6kw of energy. Using solar panels with high conversion efficiency will help you generate more energy, but will cost more.
So at the end of the day, this should really be something that you prioritise when choosing between Sunpower or LG solar panels.
Especially when price matters, and you can get high quality, value solar panels from Jinko, Seraphim, Canadian or Longi.
