To harness as much of the solar energy as you can, simply link two of these solar panels before connecting to the 300 Solar Generator System by the Grid Doctor. This combined setup results in quicker charging, reduced downtime without electricity, and a significant increase in overall power supply. 

Place one panel to catch the morning sun and the other to absorb afternoon rays, optimizing each solar panel’s sun exposure without the need for constant repositioning.

Plus, having two panels provides a backup in case one encounters an issue.
