SP70 Solar Panel 1. General Solar panels are a photovoltaic power source used for providing power to the system, as well as charging lead acid batteries. The SP70 solar panel is supplied with a 20 ft long, 16 AWG cable with two leads terminated with spade lugs. This cable connects to the external voltage regulator. The voltage regulator is not supplied with the SP70 solar panels, and must be purchased separately.
SP70 Solar Panel NOTE The above wind load data assumes that the SP70 solar panel is mounted on a CM110 tripod with extended guy wire kit (CSI p/n 19282) installed with the guy radius of 100 inches and the 100 pounds of guy wire pretension. The position of the solar panel along the tripod mast has little effect on the wind load. However, if the extended guy wire kit is not installed, the wind load is reduced to 11 m/s (25 mph) and 8.9 m/s (20 mph) for single and double panel installations, respectively.

SP70 Solar Panel FIGURE 6. Right and Left Arm Brackets are Attached to the Back of the Solar Panel Attach the mount to the back of the solar panel between the right and left brackets already in place as shown in Figure 7. Use the 5/16-18 x 0.75 Hex bolt and nuts along with the matching lock washers and flat washers. Use two flat washers for each bolt as shown in Figure 8. FIGURE 7.
SP70 Solar Panel FIGURE 8. Use appropriate lock washers and flat washers. Two flat washers are used for each Hex bolt. For pole or tripod mounting, use the two 5/16-18 x 2.0 U-Bolts included in the package as shown in Figures 9, 10, and 11. FIGURE 9. Two 5/16-18 x 2.

SP70 Solar Panel The panel should be mounted facing south if located in the Northern Hemisphere, or facing north in the Southern Hemisphere. The nuts fastening the solar panel mount to the pole or the tripod mast should be as tight as possible without bending the mount. See Figures 12 and 13. FIGURE 12. SP70 is Mounted to a Pole Using Two 5/16-18 x 2.0 U-Bolts FIGURE 13.
SP70 Solar Panel Alternatively, you can use four 5/16-18 x 1.5 U-Bolts to mount the SP70 solar panels to a tower. Select the appropriate sets of holes in the mount to match the width of the tower. See Figures 14 and 15. FIGURE 14. Two 5/16-18 x 1.5 U-Bolts are Attached to Each Side of the Solar Panel Mount for Tower Mounting FIGURE 15.
SP70 Solar Panel 3.3 Orientation The solar panel should be oriented to receive maximum insolation (incident solar radiation) over the course of a year. Suggested tilt angles of the solar panel are given in Table 2. After determining the tilt angle, loosen the 5/16" nuts on each side of the solar panel, and reposition the Hex bolt locations according to the hole location settings shown in Table 3 to adjust the panel. Tighten the two nuts to secure the position. See Figure 16. TABLE 2.

SP70 Solar Panel 3.4 Installation of Morningstar SunSaver SS-10-12V Regulator NOTE NOTE For safety reasons, completely cover the solar panel to limit output current and voltage. If nothing is available to cover the panel, be careful not to short solar panel (+) and (-) leads together. 1. Using the supplied mounting hardware, install the Morningstar SunSaver SS-10-12V regulator (CSI p/n 18529) on the mounting plate of an environmental enclosure (see Figure 17). 2.

Maintenance An occasional cleaning of the glass improves the solar panel's efficiency. If a problem with the solar panel is suspected, the panel may be checked by measuring the voltage output. Check the voltage with a voltmeter connected between the two leads of the solar panel.
SP70 Solar Panel For help in troubleshooting the solar panels, please contact Campbell Scientific, Inc. Applications Engineers. 5. Power Considerations 5.1 Proper Solar Power and Lead Acid Battery Sizes The solar panel converts light energy to electricity, or specifically to direct current. The direct current produced is used to provide power to the system and to charge lead acid batteries. The solar panel operates in both direct and diffuse light (cloudy days), but not at night.
