10 - English Setup Connecting to AC power Before using your Bose Â® SoundLink Â® Mini speaker the first time, connect it to AC (mains) power and charge the battery. You can connect the power supply cord into the charging cradle, or directly into the speaker. While the battery is charging, you can begin using the speaker.
Ann is completely right. Given the alternative energy aspect of solar lights it seems a bit funny to have them charged by electrical lighting. Given enough direct and reflected sunlight in a room, they could be charged indoors. The stored charge wouldn't be as efficient as if they were in full sunlight though.
Heating your home with an active solar energy system can significantly reduce your fuel bills in the winter. A solar heating system will also reduce the amount of air pollution and greenhouse gases that result from your use of fossil fuels for heating or generating the electricity.
