G Sheet 2

This document contains a one line diagram and load schedule for a solar power system connecting a home to the electric grid. It includes a 280 watt, 2-way net metering connection from the grid to a 2500 watt inverter. Power will be supplied from 10 250-watt solar panels producing a total of 2500 watts, meeting the home's estimated daily consumption of 10 kilowatt-hours. Notes provide details on load calculations, conductor sizing, and protection.

NOTES:
SOLAR DESIGN ANALYSIS:
1. THIS LOAD SCHEDULE IS PREPARED USING EXCEL, COMPUTATIONS ARE DONE HERE.
2. 1 Full Load = VA/Voltage (see Column O) NOTE: KWp is Killowatt per Panel
3. 180 VA per outlet at pf =1 CONSUMPTION = 10 KW-HR
4. Ampacity of conductors used is 1.25* of Full- load current (MINIMUM)(see Column P)
5. Protection is 2.5* Full-load current (MAXIMUM)(see Column S) KWp x Peak Sun Hour = KW-HR
6. Ground wire shall 14.0 sq mm colored GREEN.
7. Complete design analysis that includes computations of short circuit and voltage drop will be done next semester. Iloilo Peak Sun Hour = 5.5
KWp = 5000 W-HR/ 5.5
KWp = 1818.18
