Step 3: Adding a 15 watt solar panel

With my interest sparked again by a friend also interested in solar, I went online and purchased a northern tool 15 watt panel. The frame was a paint to install, but once attatched I immidiately noticed the battery voltage shooting up and the charge controller having to regulate the current constantly. Also, my inverter stopped yelling at me for charging my laptop, but it still would drain the battery pretty fast. Interesting what a difference 15 watts makes!
