Quick Answer
Patrols operating in remote areas may benefit from considering solar energy for off-grid living due to its reliability and environmental sustainability. Solar energy systems can provide power for essential equipment and communication devices. However, patrol leaders must weigh the costs and logistical challenges of implementing solar energy.
Understanding Solar Cold Weather Gains
Solar panels perform significantly better in cold weather conditions than previously thought, with some studies indicating up to 30% more efficiency in temperatures below 50°F (10°C). This means that patrols operating in cold climates can generate more power from the same solar panel array, making solar energy a more viable option for off-grid living. To maximize cold weather gains, patrol leaders should consider using panels with high low-light performance and inverters optimized for cold temperatures.
Planning for Solar Energy on Patrols
When planning a solar energy system for patrols, consider the following factors: system size, battery capacity, and charging/discharging rates. A general rule of thumb is to plan for a minimum of 200-300 watts of solar panel power per person on the patrol. For example, a 6-person patrol would require a minimum of 1200-1800 watts of solar panel power. Patrol leaders should also consider using high-capacity batteries, such as lithium-ion or lead-acid batteries, to store excess energy generated during the day for use at night or during periods of low sunlight.
