SP5, SP10, SP10R, SP20, and SP20R Solar Panels 1. General Solar panels provide a photovoltaic power source for charging lead acid batteries. The SP5 has an output level that will allow it to be connected directly to the “Charge +” and “Charge –” terminals on the CR200(X)-series dataloggers. The CR200(X) will then charge a 12 Vdc (7 A h or less) battery attached to the “Battery +” and “Battery –” terminals.
SP5, SP10, SP10R, SP20, and SP20R Solar Panels NOTE 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 10%. The output panel voltage increases as the panel temperature decreases. Compatible batteries: 3. SP10/SP20 SP10R/SP20R 12 V gel cell or AGM lead acid batteries such as the batteries used with the PS100, BP12, BP24, CR3000, CR5000, CR7, and CR9000(X).

Solar panel mounting The solar panel is oriented to face the equator, and then mounted to the mast using the U-bolts and 5/16 NC (course) nuts provided with the panel. The nuts fastening the bracket to the pipe must be as tight as possible without bending the bracket.

Regulated solar panel and external battery 3.2 Orientation The solar panel should be oriented to receive maximum insolation (incident solar radiation) over the course of a year. TABLE 3-1 suggests optimal angles for the solar panel through a range of latitudes. NOTE The SP5 mounting bracket has a fixed tilt angle that cannot be adjusted. TABLE 3-1.
SP5, SP10, SP10R, SP20, and SP20R Solar Panels Tilt Angle Adjustment Bolt FIGURE 3-6. Adjust the tilt angle of the SP10 For the SP20 and SP20R, the angle is set by the alignment of holes on the mount and arm brackets (FIGURE 3-7). Refer to TABLE 3-2 to determine which holes need to be aligned for the correct angle. Use the following procedure to mount the solar panel. 6 1.

SP5, SP10, SP10R, SP20, and SP20R Solar Panels implies a bad solar panel, regulator, or cable. The magnitude of the voltage output depends on the incident solar radiation. 5. Power Considerations 5.1 Solar Power and Lead Acid Batteries The solar panel converts light energy to electricity, or specifically direct current. The direct current produced is used as a charging source for lead acid batteries. The solar panel operates in both direct and diffuse light (cloudy days), but not at night.
Appendix A. Solar Panel Connector The SP10 and SP20 solar panels are shipped with the two lead wires stripped and tinned. A barrel connector (pn 788) connector must be attached to use an SP10 or SP20 with the 21XL. With the connector, the cable can be inserted directly into the 21XL Charging Port on the side of the micrologger. If it is necessary to solder the connector on the cable, please refer to the diagram below. pn 788 FIGURE A-1.
