- Use with a PWM charge controller requires 12 V (36-cell) nomimal modules. 36-cell modules typically cost more per-watt than more common modules like 60-cell and 72-cell modules.
- Operating loads with high power ratings at 12 V can require significant amounts of current. This can create issues for wire sizing and overcurrent protection device sizing.
- Operating a system with long circuits at 12 V can create voltage drop, which can require large wire sizes to ensure the system performs properly.
