Compare home, public Level 2, and DC fast EV charging costs per month, year, mile, and effective $ per kWh.

Estimate solar panels for EV charging from yearly miles, EV efficiency, sun hours, panel watts, losses, and battery setup.

Estimate how many solar panels fit on roof faces and the matching DC system size from area, panel size, and usable space.

Compare solar inverter quotes by cost, kWh value, expected energy gain, payback time, and break-even extra energy.

Calculate a solar DC to AC ratio and compare inverter sizes to find the closest match to your target ratio.

Estimate solar panel power loss from heat using panel temperature or weather, with C/F support, NOCT, and array watts.

Estimate solar panel output loss over time with yearly kWh, final-year production, lifetime energy, and dollar impact.

Estimate yearly solar kWh lost to shade, bill value lost, shaded production, and a 1-hour shade-time sensitivity check.

Estimate EV battery health from dashboard range, a charge session, or both, with a gap check for noisy inputs.

Compare battery lifetime cost per delivered kWh using price, usable energy, cycle life, efficiency, yearly use, and optional fade.
