It's obviously a great achievement though it would be nice to see improvements larger than 1-2%.
Let's hope the next one will be like a 10-12% improvement... though that's probably wishful thinking.
Storage is likely the bigger issue now.
I'm more concerned with longevity and use of more environmentally friendly materials with solar panels than efficiency. In about 30 years or so, they reach their end of life so there will be hazardous waste resulting from that.
Remember that solar just doesn’t stop working at some random day. The efficiency drops to where it makes sense to replace then people like me come in and buy the panels for pennies on the dollar because a 18% efficient panel will work just fine.
Will you be able to handle all these panels as it becomes economically reasonable for people to replace them?
