I'm no expert, but if the panels now generate additional energy/money that offsets the cost of adding these nano-tubes, doesn't that mean you can meet your power needs with less hardware, or generate extra money to sell back to the grid? It seems like what matters is whether these nanotubes generate more value than they cost.
