I'm fine if they last 5 years, as long as they are a quarter of the price of the ones that last 20, are easily recyclable and have minimal rare earth materials.

  They are not at the moment. They are just more efficient. Nirmal solar panels are 15-18%.

    Putting it that way, if they are more efficient and cost is the same and they last just as long, then the return on investment will be faster. So it's a win.
