Over the course of the last six weeks, a major focus of activity has been the design of a suitable framing for the solar plates using easily available local material. Carl was the main driver behind this, with input from the independent carpenter, Macquin.

Using the glass amorphous plate, a wooden frame and box structure was conceived, with the plate recessed in grooves cut in the frame. Since battery holders cannot be sourced in Mzuzu, a further innovation is the inclusion of a holder for recharging 3 AA rechargeable batteries.

The holder is made from electrical conduit clips. The design includes a removable back cover to allow for cooling of the panel and easy repair of the product should repair prove necessary. Also it allows for inclusion of a 'manual' for the customer. The current design has gone into production and will be tested in the field before making further changes.
