ÉSLCHS Solar Electric System

• 5760 Watt grid-tied solar electric system– 32 x 180 Watt Canadian Solar modules

• 12 modules at entrance to school• 20 modules in central area of school

– 32 x Enphase M190 208VAC micro inverters

• Enphase Enlighten per-module monitoring

• One inverter per module instead of one inverter per array of modules

• Advantages– Maximum Power Point Tracking (MPPT) per module

maximizes output of system and limits effects of shading– Cost is less for smaller systems– Monitoring system– Allows for modular systems - Start small and add later!– 15 year warranty (Standard for string inverters is 10)

• Disadvantages– Higher cost for larger systems– Demand is high– Newer product; not as proven

System 1: Front Entrance

• 2160 Watt grid-tied solar electric system– 12 x 180 Watt Canadian Solar modules

• Modules at front entrance of school

– 12 x Enphase M190 208VAC micro inverters

• Enphase Enlighten per-module monitoring

System 2: North Array

• 3600 Watt grid-tied solar electric system– 20 x 180 Watt Canadian Solar modules

• Modules in central area of school

– 20 x Enphase M190 208VAC micro inverters
