DASHBOARD VIEW PROJECT DATA GEOGRAPHIC DATA PV MODULE SPECIFICATIONS CALCULATED PARAMETERS • EQUIPMENT CONFIGURATION INVERTER OPTIONS REASONS FOR CHANGE INVERTER SPECIFICATIONS ESTIMATE THE Isc AND DLR (DC/AC RATIO) AS A FUNCTION OF: • SITE LOCATION • ARRAY CONFIGURATION TYPE • PV MODULE TYPE • TIME OF YEAR AND DAY INVERTER/DESIGN COMPATIBILITY SUMMARY ARRAY/INVERTER CONFIGURATION DESIGN TERMS AND CONDITIONS ESTIMATE DLRMAX(t) vs DLTSTC Isc. MAX (t) vs Isc. STC

STEP 1 – PROJECT AND PV MODULE INPUT PROJECT NAME AND START DATE TODAYS DATE – USEFUL TO COMPARE TO START DATE DROP DOWN SELECT NOT USED

STEP 2 – PROJECT GEOGRAPHIC LOCATION SELECT STATE (DROP DOWN) STATE SELECTION ACCURACY IS ESSENTIAL FOR DYNAMIC ANALYSIS SELECT NEAREST ASHRAE STATION (DROP DOWN) SITE/STATE SELECTION CONFLICT MANUAL TEMPERATURE SELECTION IS AVAILABLE IF TEMPERATURE DIFFERENCE >4 - WARNING MANUAL DATA SELECTABLE o. F/o. C

STEP 4 – EQUIPMENT SELECTION/ARRAY TYPE (DROP DOWN) MODULE SELECTION FOR EACH MPPT (DROP DOWN FROM CUSTOM MODULE DATA TAB INFORMATION) INVERTER SELECTION FROM A HIDDEN TAB (“DISCONTINUED” AND “COMING SOON” NOTATIONS)

STEP 5 – ARRAY/INVERTER CONFIGURATION DETERMINES THE STRING LENGTH RANGE BASED ON MPPT OR TOTAL OPERATIONAL VOLTAGE RANGE CHANGES THE INVERTER OCPD CALCULATIONS IN THE INVERTER SPECIFICAITON SECTION IF MPPTS ARE UNBALANCED THERE MAY BE ADVANTAGE TO PARALLELING THEM. GREEN/RED DESIGN STATUS INDICATION OPTIMIZATION PROMPTS COLOR CODED PROMPTS PROVIDE DATA ENTRY CLUES

STRING LENGTH RECOMMENDATIONS BASED ON SELECTED VOLTAGE RANGE STEP 6 – STRING SIZE DESIGN COMBINED PARALLEL FOR THIN FILM ISSUES HIGHLIGHTED IN RED FONT NEC ALTERNATE METHOD MAX OF Isc(3 HIGHEST AVERAGE) x 1. 25 OR 70% Isc x 1. 56
