Solar Panels / SP20R-L
SP20R-L 20 W Solar Panel with Regulator

Overview

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.

Benefits and Features

  • Supplies electrical power in locations where ac power is unreliable, expensive, or not available
  • On-board voltage regulator allows direct connection to a user-supplied external battery

Detailed Description

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).

Compatibility

Regulators

The solar panel includes an onboard regulator.

Batteries

The SP20R-L is compatible with user-supplied, flooded 12 Vdc batteries, such as deep-cycle marine or RV batteries.

Notes

  • Flooded batteries should be charged with the 18529 MorningStar SunSaver regulator or the SP20R.
  • The SP20R draws a continuous 2 mA current drain. The 18529 MorningStar SunSaver draws a continuous 8 mA current drain.
