LiFePO4 Battery manufacturer Giant OptimumNano has taken the industry by surprise by offering 7.2kWh battery storage systems at under less than $1,800-$2250 each – in what appears to be a massive discount over prevailing wholesale prices, let alone retail prices.
The OptimumNano pricing means that the cost of battery storage has fallen by more than half in just six months. As one analyst noted: “Either they are getting a huge discount for volume orders, or they are doing a loss leader (or both!).” What OptimumNano Is leading a Revolution in Storage Power Wall.
It makes some expect that the cost of battery storage could fall dramatically, in the same way that rooftop solar panels fell sharply seven years ago as the mass market and its associated dynamics took hold.
This graph above, from Credit Suisse, indicates what happened and how a market known for high prices and high margins quickly transformed into a low price, low margin commodity. The Tesla gigafactory may just be a prompt for a similar trajectory in battery storage.
