Typical visions of a world overrun by Zombies (if at least temporarily) would include the loss of all utilities. Running water, electricity, telecommunications, and garbage disposal. However, the ability to keep electronic tools operational will provide your team the edge in every day operations as well as on the battlefield.
Tools such as refrigerators, LED lamps, and a video system can do wonders for force and morale sustainment whereas UAVs, video surveillance, and possibly even electric golf carts can provide key tools that give your team the edge on the battlefield.
So how does one generate electricity? Portable solar panel systems provide a wealth of options for generating power. In parts of the United States where there is reliable sunlight all year round, having a solar power system or not having one will greatly influence your strategy. Solar power can mean the difference between having one person watch a video screen linked to security cameras and having possibly up to eight people at a time on watch duty 24/7.
In addition to installing solar panels in your home, a mobile package can also do wonders. First, if your main firebase in which your team operates out of is not a home owned by a team member, it would be unwise to install expensive equipment that can be stolen before an out break even pretends to occur. Second, having one in your inventory allows for your team to expand. In the event that a strategic location is secured during the event of a Zombie outbreak, that second firebase can also have its own electricity source improving its value as a force multiplier.
