This year we decorated for Christmas with outdoor lights that are all solar. The strings of lights in the trees and bushes are powered by small solar panels. The lights along the eaves are all pint Mason jars with 20 LEDs inside powered by a small solar panel in the lid. We get enough sun that most of the lights shine for at least 3 hours when it gets dark. My challenge for next year is to figure out how to get more hours of sunlight on them so the stay lit longer. With a full day’s sunshine they will stay illuminated for at least 8 hours. If you are interested in decorating your house with solar lights, let me know and I can tell you where to get the materials and the lessons I learned while building everything.
