Contact Tor ( 707-829-3154) for information on the latest Solar Lunchbox Design. We’ve made some modifications and are piloting this at one High School Fall 2021.  Digital Volt meter provides feedback on the state of the charge of the battery. Newer solar modules are part of the new design along with a voltage regulator.

Solar Notebooks are an alternative to the lunchbox design, with similar charging goals.
