Nature Power Monocrystalline Solar Panels take the sun's energy and turns it into electric current. These solar panels are high efficiency 12-Volt solar panels featuring sturdy aluminum frames and high transparency tempered glass tops. They are rugged enough to be permanently mounted outdoors or even on mobile applications such as RVs and boats. Designed for charging 12-Volt batteries in off-grid applications of any scale. Monocrystalline is the most efficient type of solar cell available on the market letting you get the most power per square inch. Monocrystalline solar panels are warranted to retain at least 80-percent efficiency up to 25 years. Solar Charge Controller required to control battery over-charging (sold separately).
