The SP20 is a 20 W solar panel. It is often used for system configurations that have higher-than-average power requirements, or in higher elevation and latitude locations. It connects to Campbell Scientific power supplies and battery bases to recharge the battery, and it allows unattended operation of systems in remote locations that are far from ac electrical sources.Read More
The SP20's 15-ft cable has stripped and tinned leads that connect to the PS150, PS200, CH150, CH200, or battery base of the CR3000, CR5000, CR7, CR9000X, CR6, or CRVW3. A 788 connector must be soldered onto the solar panel leads to use the SP10 with a 21XL rechargeable base.
Included mounting hardware consists of two part no. 17492 U-bolt and matching nuts. The U-bolt has a 5.398 cm (2.125 in.) space between the U-bolt legs. This hardware allows the solar panel to be mounted to a 0.75-1.5 in. IPS pipe [25.4-50.8 cm (1-2 in.) OD].

The supplier of the SP20-series solar panels changed the wiring connections so that it is no longer possible to lengthen the cables without a splice. Splices can increase the risk of water penetrating the cable, so Campbell Scientific generally recommends not lengthening the cable. However, we can lengthen the cable upon special request. Contact us to discuss this further.
The CH100 Charge Controller is designed to work with maintenance-free deep-cycle lead-acid batteries. The voltage of the charger is slightly different than what is required to charge the marine-type flooded-cell battery. Therefore, Campbell Scientific recommends purchasing a deep-cycle battery, such as the BP12 or BP24, rather than a flooded-cell battery. Note that our regulated solar panels, such as the SP20R and SP10R, are intended to be used with, and connected directly to, a user-supplied flooded battery.
Regulators control the current flowing to the battery and prevent the battery current from flowing to the charging source. These solar panels do not include an on-board voltage regulator, so a stand-alone regulator would be required to complete a power supply.
Typically, these solar panels are connected to a CH100, CH200, PS100, or PS200, as well as to the battery base of a CR3000 or CR5000. The PS100 and the PS200, as well as the battery base of the CR3000 and CR5000, include an internal regulator.
