Solar Energy

The wire size is calculated using Equation 2.20. The wire size (Aw) is usually reported in units of mm, while WL is the load in watts, V is the system voltage, and L is the length of wire in meters. The standard wire gauge in the United States is called the American wire gauge (AWG), also known as the Brown and Sharpe wire gauge. The dimensions of the wires are given in ASTM Standard B 258. The cross-sectional area of each gauge is important for determining current carrying capacity. Increasing gauge numbers mean decreasing wire diameters. For example, AWG#16 has a diameter of 1.291 mm [0.0508 in], AWG#14 has a diameter of 1.628 mm [0.0641 in], AWG#12 has a diameter of 2.053 mm [0.0808 in], and AWG#10 has a diameter of 2.588 mm [0.1019 in]: Awmm=0.04×WLV×L

Wire gauge (alternatively spelled “wire gage”) is indicative of electrical conductor wire diameter, with primary implications for allowable current flow (amperes). According to working tables published for Standard Annealed Solid Copper Wire (Ref. 3–17), 20-gauge wire has a diameter of 0.032 inches and, at a temperature of about 40 degrees F, has a resistance of approximately 11 ohms per 1000 ft of length. While suction strainers have nothing to do with electric current, we assume that the same wire diameter (i.e., roughly 1/32 of an inch) also applies to the stainless steel wire used in wire mesh. For the pump suction strainer in Figure 3-53, an as yet undefined size of “mesh” is to be placed inside the three-mesh guard screen.

Conductors are generally aluminum or copper. Square and rectangular shaped wires have rounded edges. The arcs of the radii of the rounded edges must merge smoothly into the flat surface of the wire. This is to avoid any sharp edges that could pierce the insulation. Square and rectangular wire types can increase the slot fill factor compared to round wires, since there is less space between wires. Wire sizes are given in the American Wire Gauge (AWG) sizes, where larger gauge numbers indicate smaller diameters of wire.

Several solar modules are connected with the help of wires to generate electricity from them. During the reconfiguration process, more wires are needed because the modules are physically relocated. This study incorporates a polycrystalline solar module SYN-10W rating. The size of the wire for solar module connections is decided by its current carrying ability. Thus, as per the National Electrical Code (NEC) wire should have the ampacity of 1.56. So, a 12 American Wire Gauge (AWG) is chosen for this purpose (Wiles 2001).

An important parameter required for the construction of the coil was the selection of the wire gauge. For safety, copper-enameled wire of 18 American Wire Gauge (AWG), having a current capacity up to 10 A and a diameter of 1.024 mm, was selected for the construction of the exposure system. The coil was professionally wound on a wooden frame of radius 15 cm with 200 turns in each coil and separated by a distance equal to the radius to obtain a uniform field strength.
