The system consists of a 45 watt PV panel, a charge controller to regulate battery charging, an off the shelf power pack that contains both the battery and inverter, and a PVC pipe rack you make to support the panel.
The system will provide power for things like a laptop, some modest lighting, charging cell phone batteries, and a number of other things that are very handy to have in an emergency.
The instructions are very detailed and the project is easy to build. A good way to get started with solar.
Thanks very much to John for providing this material!
