The SP20R is 20-W photovoltaic power source capable of recharging batteries. It has an on-board voltage regulator, and a 6.1 m (20 ft) cable with stripped and tinned leads that connect directly to a user-supplied deep-cycle battery.
The SP20R is often used for system configurations that have higher-than-average power requirements, or in higher elevation and latitude locations. It allows unattended operation of systems in remote locations, far from AC electrical sources.Read More
The SP20R includes mounting hardware consisting of the the pn 17492 U-bolt and Matching Nuts. The pn 17492 U-bolt provides a 2.125" (5.398 cm) space between the U-bolt legs. This hardware allows the solar panel to be mounted to a 0.75" to 1.5" IPS pipe (1" to 2" OD).
Please note that the SP20R has a 2-mA continuous current drain (meaning that it consumes a small amount of power from the connected battery at night).
|-NOTE-||Solar panel characteristics assume 1 kW m-2 illumination and 25°C solar panel temperature. Individual panels may vary up to 10%. The output panel voltage increases as the panel temperature decreases.|
