Abstract
This chapter deals with solar-powered Access Point and repeaters. The first thing we need to know about setting up a solar-powered AP or repeater is how much power the electronic gear will draw. After calculating the power requirements, there is need to select appropriate battery. All of the battery types are of lead acid; these batteries can go much deeper into the charge/discharge cycle without damaging the battery. These batteries are further divided into two main categories: flooded and gel cell. The flooded type contains water and must be checked from time to time to make sure the cells are completely immersed in H2O. They do typically offer more energy storage capacity then the gel cells and cost a bit less. On the other hand, gel cells require no maintenance at all. Therefore, they are sometimes referred to as “maintenance free” batteries. These batteries typically come in 6- and 12-volt flavors and a whole variety of storage capacities, referred to as amp hours, or Ah. Just like batteries, solar panels are rated with voltage and amperage values; however, they are usually measured by overall wattage. Solar panels can be purchased in a myriad of different wattages, from 1 to 180 watts. The chapter also outlines the construction materials and techniques implemented during the construction of the SoCalFreeNet solar node. For the SoCalFreeNet node, a six-terminal block was used. The 12V supply from the batteries is fed to the first two terminals via 12 AWG wire, terminating in ring connectors.
