The SP5-L is a 5 W solar panel that is typically used as a recharging source with our CR300-series dataloggers, as well as our CRVW3. It may be suitable for use with other data loggers, provided that the system's power recharge requirements are low enough. The SP5-L cable has a user-specified lead length that terminates in pigtails to attach directly to the terminal strip of the data logger.
