Solar Charging Station ROI
Estimate ROI on a depot-mounted solar PV array used for EV charging or auxiliary depot loa
Formula: install_total_cost = system_kw * install_cost_per_kw; annual_kwh_generated = system_kw * daily_sun_hours * 365; annual_savings = system_kw * daily_sun_hours * 365 * electricity_aed_per_kwh; payback_years = (system_kw * install_cost_per_kw) / max(system_kw * daily_sun_hours * 365 * electricity_aed_per_kwh, 1); lifetime_savings = system_kw * daily_sun_hours * 365 * electricity_aed_per_kwh * system_life_years - system_kw * install_cost_per_kw
