Super-capacitors are highly reliable devices, outlasting any existing battery in operating conditions, cycle number and
ruggedness. They are perfect candidates for energy storage in remote wireless sensor network nodes. Other applications
 use a combination of rechargeable battery as the main storage device and a low capacity EDLC as energy buffer. This
paper describes the design and the results from a module consisting of a single large capacitor, a MPPC charger and a
boost converter. Unlike other devices, this prototype uses one storage device (a single EDLC), it does not involve
software components  and it can operate from a single solar cell.
