Detailed Financial Projection

How Is the Battery Return on Investment Calculated?

Investing in energy storage systems is increasingly popular alongside solar PV setups or for exploiting time-of-use energy tariffs. This calculator factors in key technical and financial metrics:

  • Usable Capacity (DOD - Depth of Discharge): To preserve battery health, systems rarely discharge to 0%. The calculator automatically factors in a 90% depth of discharge.
  • Savings per Cycle: Derived from actual usable energy capacity multiplied by your electricity price differential (€/kWh).
  • Annual Savings: Calculated by multiplying single-cycle savings by total yearly cycles (typical residential usage ranges from 200 to 250 cycles annually).

Frequently Asked Questions (FAQ)

Cycle count depends on your household energy consumption and solar system size. In summer, a battery may complete over one cycle per day, whereas winter yields fewer full cycles.

Modern Lithium Iron Phosphate (LiFePO4) batteries typically endure between 6,000 and 10,000 charge cycles, corresponding to approximately 15 to 20 years of continuous operation.
