1 Diode is roughly 1 or 2 solar cells equivalent depending on forward voltage. We want to be able to do up to 30V output voltage even at low currents, so we need 30/0.7 = 42. We’ll go with 40 diodes since the ones we’re using have slightly higher voltage drop. 20 diodes on each heatsink.
Diode spacing: 200mm x 70mm heatsink
Diodes about 20mm tall, 10mm wide. 20mm horizontal spacing.
Heatsink can dissipate 300W - user should be responsible for obeying this. Safety features could be added in the future (Arduino-controlled MOSFET with a bunch of temperature sensors, voltage sensor, and current sensor).
Rshunt: 0.1Ohm should be good. P = I^2 * R = 10*10*0.1 = 10W
Rseries: 1k should be good. P = V^2 / R = 30*30 / 1000 = 0.9W
Power Input and output connectors : Banana jacks(and remote sense)
