FIGURE 3-20: Solar charger<br />

With these kinds of solar panels, you have power for a variety of applications:<br />

Charging batteries<br />

Outputting a 12-volt supply for use with a power cord, as shown in Figure 3-21<br />

Outputting a lower voltage<br />

All you need, to have all the power you want, is sunlight. If you are traveling from and returning<br />

to a base camp daily, then you may be better off using the system to recharge batteries. You<br />

can also strap it to your backpack and use it on the move, as shown in Figure 3-22.<br />

You can also use the solar charger system to power other devices too, such as cell phones.
