Application
This document is provided as guidance. Installation of a
utility-interactive solar photovoltaic system generally
requires a permit from the local authority having
jurisdiction (AHJ). This document provides a typical format
for a residential permit application to install a SunSource®
Home Energy System.

A1 — System Summary
For Construction: March 15, 2013
Project #: 412
Client: Mr. Jeff Bailey
Address: Corsicana, TX
System Size: 3.180 kW
Module: Solar World SW-265
Microinventer: Enphase
Project Report
The following design describes a Solar PV system with a peak STC DC size of 3.180 kW
and an estimated electrical generation of 4828 kWh per year.
The modules are mounted on the south facing roof with an 185º azimuth at a 32º tilt. The solar PV AC array consists of
(12) SW-265 solar modules with each solar module in the array connected to an Enphase M215 microinverter. They
have 96% CEC efficiency rating
From each module, DC power is connected directly to an Enphase microinventer mounted below each module.
240VAC power from the microinventer passes through a renewable energy credit meter; next, through a disconnect
switch and then ties into solar source breaker located in the Lennox SunSource®XC21-060 (5-Ton) air conditioner.
Utility: United Cooperative Service
