SP50-L/SP90-L Solar Panel 1. Introduction Solar panels convert light energy to electricity, or specifically to direct current. The direct current produced is used to provide power to a system and to charge lead acid batteries. Solar panels operate in both direct and diffuse light, but not at night. A user-specified 16 AWG cable comes with each solar panel. External voltage regulators, rechargeable batteries, and rechargeable power supplies must be purchased separately.
SP50-L/SP90-L Solar Panel NOTE Depth: 5.0 cm (2.0 in) 5.0 cm (2 in) Weight: 6 kg (13.2 lb) 7.7 kg (17.0 lb) Max. wind speed @ angles greater than 35°: 29 m s–1 (65 mph) 24 m s–1 (55 mph) The above solar panel characteristics assume a 1 kilowatt per square meter illumination and a solar panel temperature of 25°C. Individual panels may vary up to 5%. The output panel voltage increases as the panel temperature decreases. TABLE 2-2.
SP50-L/SP90-L Solar Panel Two SP90 Solar Panels in Parallel SP90 SP90 Regulator Box Regulator Box black black red red – + + – All SP90 solar panels shipped after February 2013 have the SB1245 blocking diode installed inside the junction box on the back of the panel. The blocking diode allows two SP90 solar panels to be connected to a single Morning Star SunsaverTM regulator as shown. Solar – Solar + Morning Star SunsaverTM Regulator FIGURE 2-1.

Attach the mount to the back of the solar panel between the right and left brackets already in place as shown in FIGURE 3-7. Hint: jump to Section 3.3, Orientation, to determine which holes to use in order to mount the panel at the optimum angle for the site’s latitude. Use the 5/16-18 x 0.
SP50-L/SP90-L Solar Panel For pole or tripod mounting, use the two 5/16-18 x 2.0 u-bolts included in the package as shown in FIGURE 3-9, FIGURE 3-10, and FIGURE 3-11. To prevent damage to the solar panel, it is recommended that two people mount the solar panel. FIGURE 3-9. Two 5/16-18 x 2.0 u-bolts are used for pole or tripod mounting FIGURE 3-10. Lock washers and flat washers are used to secure the two 5/16-18 x 2.
SP50-L/SP90-L Solar Panel FIGURE 3-11. The solar panel is ready for pole or tripod mounting 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 FIGURE 3-12 and FIGURE 3-13. FIGURE 3-12. The solar panel is mounted to a pole using two 5/16-18 x 2.

SP50-L/SP90-L Solar Panel Alternatively, you can use four 5/16-18 x 1.5 u-bolts to mount the solar panels to two legs of a triangular tower. Select the appropriate sets of holes in the mount to match the width of the tower. See FIGURE 3-14 and FIGURE 3-15. FIGURE 3-14. Two 5/16-18 x 1.5 u-bolts are attached to each side of the solar panel mount for triangular tower mounting FIGURE 3-15.
SP50-L/SP90-L Solar Panel 3.3 Orientation The solar panel should be oriented facing the equator to receive maximum insolation (incident solar radiation) over the course of a year. Suggested tilt angles of the solar panel are given in TABLE 3-2. 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 3-3 to adjust the panel. Tighten the two nuts to secure the position.

SP50-L/SP90-L Solar Panel 3.4 .4 Installation of CH200 Regulator 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 CH200 on the mounting plate of an environmental enclosure (see FIGURE 3-17). Verify the On/Off switch is in the ‘Off’ position. 2a.

Connect the red (+) wire from the solar panel power cable to terminal lug #4 marked solar (+) on the regulator. If using a sealed rechargeable battery (BP24, BP84, or PS84), verify that the metal jumper is installed to configure the regulator to recharge sealed rechargeable batteries (see FIGURE 3-18).
