The controller that came with the solar panels is quite impressive.
Thunderbolt 25 watt solar panel review.
Each of these panels can generate a maximum of 25 watts of energy every single hour all day long.
When combined all 4 panels produce a combined total of 100 watts of energy per hour.
Constructed of amorphous crystal this panel provides superior performance in bright sun and in partial shade.
One solar panel was already cracked then a bulb didn t work then another one burned out in a week.
Maintain large capacity 12 volt batteries on rvs or marine applications.

The thunderbolt magnum solar kit features 4 separate solar panels.
It has a digital display that s large and easy to read and shows the remaining voltage in the battery power.
