A photovoltaic system is disclosed having individual micro-inverters associated with each solar panel. The individual micro-inverters are easily installed without the aid of tools by snap locking a micro-inverter into place upon heat barriers mounted to and separated from the solar panels. When a micro-inverter is snapped into place it automatically electrically engages contacts from the solar panels mounted on the heat barriers. AC trunk cables pass through uni-strut channels along the backs of the solar panels. Flat jumper output cables from the micro-inverters fit adjacent the AC trunk cables within the uni-strut channels where a snap fit electrical connection is made, in a protected environment.
