If you have different wattage solar panels, the same voltage but different amps, which is the better way to wire the solar panels together in your DIY solar system – series or parallel? In this video, we take two 24V solar panels, and wire them in parallel and in series into an MPPT charge controller to a deep cycle battery. Then we’ll, measure the output to determine which method is better for maximizing your solar power production. The results may surprise you.

(Visit: All of us contribute to the greenhouse gas emissions that are causing climate change. But there are ways to reduce our carbon emissions. How we travel, what we eat, what we consume and what we discard are just some of the factors that contribute to our carbon footprint. Louis S. Santiago, an assistant professor of physiological ecology at the University of California, Riverside, explains how we can measure our impact on our climate. He argues that we can all do something to reduce our carbon footprint. Series: “Earth 101: What You Need to Know About Life on our Planet” [9/2012] [Science] [Show ID: 24208]
