Electrical

Estimate lighting kWh, monthly cost, yearly cost, upgrade savings, and payback with flat or peak/off-peak electricity prices.

Estimate LED bulb electricity savings by watts, bulb count, use time, and $ per kWh, with an optional lumen brightness check.

Estimate bifacial solar rear-side gain, added power, and yearly energy with albedo, bifaciality, peak sun hours, and sensitivity settings.

Estimate solar self-sufficiency, grid imports, exports, battery shift, and monthly bill impact using kWh, rates, and solar production.

Compare 12V, 24V, and 48V solar sizing for battery Ah, inverter DC amps, controller amps, and a planning voltage pick.

Estimate solar LCOE in $/kWh with simple and adjusted results for discounting, output drop, maintenance, and replacement cost.

Estimate solar panel cleaning payback from recovered kWh value, cleaning cost, dirt loss, and home-use versus export rates.

Calculate solar panel row pitch, shade gap, GCR, rows that fit, panel count, and DC system size from tilt and sun angle.

Calculate NEMA three-phase voltage unbalance, average voltage, misses from average, and true line-to-line comparison.

Size a VFD by output amps for one motor or several motors using nameplate amps, service factor, load type, and ratings.
