Solar EV Charging and Energy Planning

Compare annual EV energy offset and interval solar charging availability using vehicle acceptance, charging losses, other loads and actual site output.

Check configured EVSE AC current against ordinary circuit limits, then estimate charging energy and time using vehicle acceptance and efficiency.

Estimate instantaneous PV power from operating conditions or integrate actual AC intervals; keep module temperature, inverter clipping and energy separate.

Calculate a transparent solar-array nameplate and energy scenario from entered panel count, peak sun hours, losses, and annual site electricity.

Value self-used solar and exported energy with their own rates, realizable credits and additional charges; retain the actual tariff assumptions.

Compare two actual inverter proposals using quoted costs, modeled annual energy, self-use and realizable export value; show the incremental cost and benefit.

Calculate an explicit annual-decline energy scenario or annualized change between normalized measurements; handle zero decline, zero output and measured growth.

Evaluate dated annual solar cash flows or an explicit escalation scenario, including replacements, discounting and recovery that can reverse later.

Compare net upfront cost with constant annual benefits and costs; handle zero outlay, nonpositive savings and the chosen horizon explicitly.

Look up NASA POWER monthly horizontal solar climatology by coordinates, preview and explicitly apply the data, or summarize a documented manual monthly series.

Convert daily solar irradiation into equivalent peak-sun-hours or integrate measured irradiance intervals; preserve the actual plane and period.

Compare actual tilt and azimuth candidates using interval irradiance or entered modeled yields; retain the tested period, feasible tilt limits and tied results.

Compare PV DC/AC nameplate ratio, simultaneous AC watts and VA, timed peak ratings and the actual battery-voltage and current envelope.

Correct module Voc and Vmp at design temperatures and find whole series/parallel strings within startup, MPPT, absolute-voltage and current limits.

Compare documented cable candidates for loop voltage drop, loss, adjusted ampacity, terminal current and maximum circuit voltage without a fallback gauge.
