Integrated roof module and modular roof system thereof

A solar-electrical energy distribution system comprising:

• a first Photo Voltaic (PV) sub-system comprising:
• a first PV array configured for producing electrical energy from solar energy;
• one or more first energy consuming units configured to consume electrical energy;
• and
• a first charge controller operatively coupled to the first PV array and to the one or more first energy consuming units, and configured for controlling energy distribution to the one or more first energy consuming units;
• a second Photo Voltaic (PV) sub-system comprising:
• a second PV array configured for producing electrical energy from solar energy;
• one or more second energy consuming units configured to consume electrical energy;
• and
• a second charge controller operatively coupled to the second PV array and to the one or more second energy consuming units, and configured for controlling energy distribution to the one or more second energy consuming units;
• and
• a master charge controller operatively coupled to the first and second charge controllers, said master charge controller being configured to exchange electrical energy produced by at least one of the first and second PV arrays with each of the first and second charge controllers and to control energy distribution between the first and second charge controllers and an external grid.

A kit comprising:

• at least one first PV roof module inter-connectable with at least one other like-module to form a roof of a building, said first PV roof module being configured for producing electrical energy from solar energy;
• a first charge controller configured for operatively coupling to the first PV roof module and controlling distribution of electrical energy produced by the first roof module to one or more first energy consuming units;
• at least one second PV roof module inter-connectable with at least one other like-module to form a roof of a building, said second PV roof module being configured for producing electrical energy from solar energy;
• a second charge controller configured for operatively coupling to the second PV roof module and controlling distribution of electrical energy produced by the second roof module to one or more second energy consuming units;
• and
• a master charge controller configured for operatively coupling to the first and second charge controllers to exchange electrical energy with each of the first and second charge controllers and to control energy distribution between the first and second charge controllers and an external grid.
