Expanding my Solar Power System with a 15watt panel and a Hub

In this video I expand my solar power setup with a 15 watt panel. I connect it to the 1.5 watt panel with a hub from harbor freight. while the 1.5 watt panel alone struggled to keep my battery from discharging. the 2 solar panels together were able to charge the battery to full capacity in only a few hours. I need to buy a charge controller.
