Yeah I guess you're right. 0.09 vs 0.12 for the T9. Would you say a $100 difference in price is justified? So $12xx for your S9?
The T9 being 25% less efficient than S9 would cost $25 more to operate per month assuming a US national price of 0.11/KwH. If it is expected to have a 18 month running lifetime, the T9 should be discounted $450 to S9. Total suckers game to purchase T9.
