Quick Answer
Solar chargers can be viable for long-term wilderness living, but they require careful planning and maintenance to ensure reliable power generation.
Choosing the Right Solar Charger
When selecting a solar charger for long-term wilderness living, consider the device’s power output, efficiency, and ruggedness. Look for chargers with high peak power ratings (at least 10 watts) and efficiency ratings above 20 percent. For example, a well-regarded option is the Goal Zero Nomad 7 solar panel, which produces 7 watts of power and has an efficiency rating of 22 percent.
Optimizing Solar Power Generation
To maximize solar power generation, it’s essential to position the solar charger correctly. Aim to face the panel towards the sun at an angle of 30 to 40 degrees, depending on your latitude. Use a compass to ensure the panel is aligned with the sun’s rays. Additionally, consider investing in a solar charger with a built-in tilt function or a portable solar panel mount to simplify the setup process.
Battery Selection and Maintenance
A well-maintained deep cycle battery is crucial for storing excess solar power for later use. Consider a 12-volt lead-acid or lithium-ion battery with a capacity of at least 20 amp-hours. To extend the battery’s lifespan, maintain a state of charge between 20 and 80 percent, and avoid deep discharging. Regularly check the battery terminals for corrosion and clean them as needed.
