How does the Commercial EV Fleet Fast-Charging & Solar Microgrid Underwriter calculate financial return and payback?

The solver models gross capital expenditure (CapEx), Section 48 Investment Tax Credits (ITC 30%–50%), 5-year MACRS accelerated depreciation, utility demand charge shaving, and levelized cost of energy (LCOE).

Does this calculator account for battery degradation over time?

Yes, it models standardized degradation curves (typically 1.5% to 2.2% annually for LiFePO4 cells) and accounts for battery pack augmentation cycles across a 20-to-25 year lifecycle.

What federal tax credits apply under the Inflation Reduction Act?

Under Section 48 and Section 45Y, qualifying clean energy and battery storage installations unlock a 30% base ITC, plus potential 10% domestic content and 10% energy community bonus adders.
