ESSAY ON GREENS

Ground Renewable Expeditionary Energy System (GREENS) is more flexible than SPACES. The main concept of GREENS is to use different sources to generate energy. It reduces the need of fossil fuel and distributes the energy to different sections. Marines use GREENS to generate 300 watts of power. A few GREENS modules can be connected together if more power is needed. There are three configurations for GREENS. Configuration 1 is capable to generate 600 watts for 12 hours, configuration 2 is for 300 watts for 12 hours and configuration 3 is capable to generate 150 watts for 12 hours. Like SPACES, two marines can set up GREENS in twenty minutes. The system is capable of delivering power after 5 minutes of setup. The system inputs are AC, solar panels and high voltage DC and converts to low voltage DC to use in the components. In Figure 5, GREENS interconnection systems with different equipments are shown. …show more content…
Marine uses DC Power Distribution Kit (PDK) that reduces power loss by using direct DC instead of less efficient AC. A PDK kit contains a power distribution unit and different types of cables. GREENS has a vehicle mounted battery charger and inverter to distribute power to different equipment in the battlefield. The GREENS stores power in batteries for future uses. Also, this system is good because the primary energy source, which is solar energy is not available all the time. In day time, the system is able to generate more power than at night. The GREENS stores excess power to different batteries. This helps to cover the necessity of power at night or cloudy weather. The benefit of solar systems are, they can work with little or no supervision. They just need to cleaned regularly to protect them from dust, which may reduce sun radiations on the panel. The panels to be wiped regularly with water and a
