Highly efficient solar cells

Sun and Moon Jars ANY BRIGHT IDEAS

We hear lots of bad news about the environment. But there’s plenty of good news too. We need it. So here are some pieces of good news. The Sun provides almost all the heat and light Earth receives and therefore sustains every living being. When it comes to renewable energy, everybody wants to have it to lighten them up there homes, any bright ideas what it is? Highly efficient solar cells are stored inside the jars, which are powered by a rechargeable battery and LED lamps. The magic begins when the jar is placed in direct sunlight to create an electrical current which charges the battery over the course of a few hours. The energy stored inside the jar is used at night to power the LED lamps.

The frosting on the jar diffuses the light to give it the appearance of sunlight coming from the jar. There’s no switch on the jars, nor are there any visible controls. The light sensor located inside the jar activates the LEDs in the jar when it gets dark, so you have light where ever you go!

Because the Jar is built inside a mason jar, its air and water tight, which means the jar can be left outside in any weather conditions. The jars make great garden lights, as well as night lights for small children. Because the jar needs direct sunshine to work, it’s best to place them in a window which gets lots of shade. The Sun and Moon jars use an AA battery, which is completely replaceable.
