Placeholder file: schematics/solar_v1.pdf
Suggested schematic sections (create and export as PDF/SVG):
- PV array configuration (series/parallel) → PV fuse → SPD → Waveshare PV+
- Battery: 18650 protected pack → Waveshare BAT+/BAT- (show polarity)
- Waveshare outputs → buck / 5 V / 3.3 V rails → Pico / ESP32
- Load switching: MOSFET driver (D4184‑M) → solenoid with diode across coil
- Safety: fuses, blocking diode, grounding points
