We need power! While doing bird research in the wilds of northern NH, it became evident we needed electricity to power computers, big cameras, and phones/GPS units.
Below is a table of the system and our expected electricity needs:
| System | Solar 100w | 35ah universal (x2) | ||
|---|---|---|---|---|
| Ah per day: | 33.33333333 | 35 | TOTAL Ah Reserve: | 70 |
| V | 12 | 12 | Parallel wiring: | 12v |
| Wh in: | 400 | 420 | TOTAL Wh Reserve: | 840 |
| W | 100 | |||
| Cost | $105.00 | $64.00 | ||
| ah/$ | 2 | |||
| Sun Hour / Multiplier | 4 | 2 | ||
| Need/Day | Wh | multiplier | consump. in Wh = | 259.36 |
| Computer | 100 | 2.5 | 250 | |
| iPhone | 1.7 | 2 | 3.4 | |
| AAs | 11.2 | 0.3 | 3.36 | |
| Camera | 2.6 | 1 | 2.6 |
The milk crate system below can charge a 100 watt MacBook Pro around 8-9 times from being completely empty.
Remember: V*A=W, W/V=A, and Watts over time is Wh.

+/- relates to size of standard prongs
Parallel maintains 12v but doubles Ah. (Series would go to 24v at 35ah)
