SOLAR ELECTRIC SYSTEM PROJECT - 529.20 kW STC DC RATING

SOLAR ELECTRIC SYSTEM

THIS PROJECT DESCRIBES THE INSTALLATION OF A SOLAR PHOTOVOLTAIC (PV) SYSTEM. THE SYSTEM WILL

NOT BE A NET ELECTRICITY EXPORTER TO THE UTILITY GRID.

THE INSTALLATION CONSISTS OF FIXED TILT PHOTOVOLTAIC MODULES MOUNTED ON THE ROOF OF THE

BUILDING USING SELF BALLASTED PANEL CLAW POLAR BEAR HD RACKING SYSTEM. THE SYSTEM WILL ALSO

INCLUDE SEVENTEEN INVERTERS AND AN UTILITY AC DISCONNECT TO ISOLATE THE SYSTEM FROM THE

UTILITY GRID. THE PROPOSED INVERTERS ARE LISTED TO UL1741 FOR POWER QUALITY AND SAFETY.

THE SYSTEM WILL BE INTERCONNECTED TO AND WILL BE OPERATED IN PARALLEL WITH THE LOCAL ENERGY

PROVIDER ELECTRIC GRID PER THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE.
