Objectives Students will be able to describe, in
very simple terms, at least three differences ( hardware differences and/or operational differences) between a pure grid-tied solar-PV system and a stand-alone solar-PV system.
Students will be able to list, and briefly describe (in very simple terms), the basic steps for sizing a stand-alone solar-PV power system.Source:

Utility-Tied PV
System is very simple, with few components.
System is sized almost strictly by budget. “How much can you afford to buy?”
System is modular and expandable in building-block-increments.
System does NOT provide back-up power when utility shuts down.
Can be configured to provide back-up power; but, involves additional equipment and more expense.
PV voltage approaches 600VDC!

Simple Stand-Alone System

Stand-Alone PV System is more complex and more
expensive than pure grid-tie. System is sized by load analysis. System is modular and expandable in
building-block-increments. System IS back-up power when utility not
available. Requires monitoring and battery
maintenance. You must operate within your ENERGY
budget. PV voltage typically 12VDC, 24VDC or
48VDC, nominal.

Sizing a Stand-Alone System See In-Class Worksheet Do you have proper solar access? Do your load analysis. Size your battery – days of autonomy. Size your PV array – recharge in a
day (or two, max.) Size system for worst-case
conditions!

Final Notes Illinois now has mandatory net-
metering! If you have utility available, USE IT! 30% investment tax credit for next 8
years! 50% grants/rebates available from
State (maybe)! Production tax credit?
