SOLAR FLAIR WORDS: COLLYN RIVERS NEW TO THE RV LIFESTYLE? HERE’S A QUICK INTRO TO SOLAR… A significant issue when choosing solar panels for RVs is ensuring maximum output for their size. Until recently, the two main contenders were monocrystalline and polycrystalline. As both developed, there ended up being virtually no difference, excepting that once over a cell temperature of 65°C, a monocrystalline module had about 1% more output. Eventually, the California Energy Commission reported that, in real-world usage (not manufacturers’ claims and specifications), a polycrystalline panel performed the same as a monocrystalline panel. A considerable change over the past decade is cost. Solar capacity is now more than 80% cheaper than in 2012. In that era, the limitation was how much one could afford. Now, the limiting factor is available space for solar panels.
