Lithium-ion vs Lead-Acid cost analysis

 

We take the example of a solar installation for a standalone building (Self Sufficient Home). The storage capacity for the battery is 50KWh.

The application need is summarized in the above table:

SPECIFICATIONS VALUE

Stored Energy
50KWH
Cycling frequency 1 x discharge/charge per day
Average ambient temperature 23°C
Expected Lifespan 2000 Cycles, or 5.5 years

 

The costs of delivery and installation are calculated on a volume ratio of 6:1 for Lithium system compared to a lead-acid system. This assessment is based on the fact that the lithium-ion has an energy density of 3.5 times Lead-Acid and a discharge rate of 100% compared to 50% for AGM batteries.

 

 

Based on the estimated lifetime of the system, the lead-acid battery solution-based must be replaced 3 times. Lithium-Ion solution-based is not replaced during operation (2000 cycles are expected from the battery at 100% DoD cycles)

 

The cost per cycle, measured in € / kWh / Cycle, is the key figure to understand the business model. To calculate it, we consider the sum of the cost of batteries + transportation and installation costs (multiplied by the number of times the battery is replaced during its lifetime). The sum of these costs is divided by the net consumption of the system (50kWh per cycle, 365 cycles per year, 5.2 years of use).
