Jeff House Solar Panel
6000 watts peak power
1.4 hours, bad day
2.5 hours, regular
7.2 hours, good day in summer!
Solar Pathfinder
Avoid shading (like kinking a hose)
Solar irradiance meter
Energy - aware design (power, read sensors, deep sleep)
Feathers and ESP32 easier to wake up than arduino nano
Low - power design: power options, clock speed, deep sleep, power down required peripherals, reduce frequency, adjust actions accordingly with the available energy
Sleepy dog library from adafruit
Sun provides 1000 W/m2, Photovoltaic panels can get 10 to 25% and our project can get 75% out of it
Lithium battery
MiniBoost 5V, 2-5V to 5V@1000mA (Adafruit)
