Field Math & Array Optimization

AzimuthSplitting east and west doesn't just shrink the noon spike — it reshapes the day into two smaller peaks (morning + afternoon) with a dip at solar noon, because neither half of the array is ever pointed straight at the sun.

ClippingWhen raw generation exceeds your inverter limit, the excess is chopped flat — overpaneling captures early/late sun at the expense of noon waste.

C-RateCurrent divided by amp-hour capacity verifies your storage bank can handle the charge rate safely without thermal degradation.

Calculator Keys For This Lab

C4 ×Wh = Ah × V, and Raw Solar = panel × sun% × efficiency × orientation — every step in this lab that combines two numbers into one bigger one uses Multiply.

E5 %Sun conditions, controller efficiency, and the orientation factor are all percentages cutting into the panel's rated output.

B4 −Net Flow = Actual Output − Load. Subtract tells you whether you're charging or draining.

D4 ÷Used twice: Net ÷ Voltage gets you current, then Current ÷ Ah gets you the C-rate.

— no key —Capping raw solar at the inverter limit (min of the two) isn't a button — it's a judgment call you make by comparing the two numbers yourself.
