5 topics in this discipline

Renewable Energy Calculate a value

From appliance energy to module count, with the derating that stops an array from under-delivering.

Renewable Energy Calculate a value

Converting daily demand and autonomy into stored energy, and why depth of discharge changes the answer so much.

Renewable Energy Diagnose a problem

Continuous rating versus surge capability, and the load types that decide which governs.

Renewable Energy Calculate a value

Controller current from array size and battery voltage, and what happens when the array is oversized for the bank.

Civil & Structural Understand a concept

The conversions and dimension slips that produce plausible-looking but wrong answers, and how to catch them.
