BSP4012 12 Volt 40 Watt Solar Panel

The 40 watt solar panel has an output of 2.4 amps of DC power during peak solar hours. This panel must be used with a controller, as it is large enough to overcharge batteries without one. 40 watts of solar can be used for charging and maintenance of 12 volt batteries up to about 250 amp hours of capacity and replace energy consumption, giving from 9 to 17 amps or more in a day. This can be appropriate for remote telemetry, radio repeaters, LED signs, RV battery maintenance, and other such applications where the amp draw fits the output. The BSP4012 solar panel is an aluminum framed, commercial grade unit for long term exterior use, and has 15 feet of UV resistant cable permanently attached.

Applications for the BSP4012 40 Watt Panel

This 40 watt panel is used for battery recharging in small solar systems where the current draw is small (2 to 12 amps total in a day). A solar controller such as the Morningstar SunSaver 6 should be used with this panel, or any solar panel over 5 watts output. We use this panel in 12 volt applications or series two panels for 24 volt applications.
