Abstract: A modular solar lamp is provided. The lamp has three detachable modules: a solar panel module, a battery/light module, and a diffuser module. The battery/light module has a battery connected to a light. Electrical connectors are located on a surface of the body and are electrically connected with the battery. The solar module has a solar panel exposed on its top surface for converting solar energy into electrical energy. Electrical connectors are located on a surface of the module and are electrically connected to the solar panel. The electrical connection is established between the solar panel and the battery module when the two modules are fully secured to each other thus establishing an electrical connection between the solar panel and the battery through the connectors. Once the battery is charged, the solar panel module may be detached and used to charge the battery of another lamp.
