5.2 kW System
This PV array was installed on a 30 foot long garage with an unobstructed southern exposure. Twenty, 260 watt solar modules were placed in 4 rows across 5 columns. The modules are connected to a 5 kW Sunny Boy inverter via two strings of 10 modules each.

This is the first system that Greg Cole installed in September 2014. Greg installed the system on his own garage with 4 of the founding members of EnSegs to reduce his family’s impact on the environment and to truly understand all the issues around owning a photovoltaic system.
Trevor starts the installation of the flashings. Once the layout has been completed the installation of the flashings starts. Each shingle needs to be lifted so that the flashings can be placed under them.
Caulking is applied to the bottom of each flashing. If any water happens to get under the flashing it is directed away from the penetration. Note there is no caulking at the bottom of the flashing to allow moisture to escape.
The flashings are installed under the shingles. Note temporary caulk lines are snapped along the roof trusses and where the rails will run. This flashing is a product of Quick Mount PV.
The L-feet or L-brackets attach to the roof through the flashings. They also connect the rails to the roof.
The End-Clamps secure the solar panel to the rails.
Mike makes a few final adjustments to ensure the rails are level.
The rails sit ready for the solar modules.

The first module is installed with two end clips and two mid-clips. The positive and negative leads are plugged into the next module in the string.
The SMA Sunny Boy 5000TL Inverter was installed in the garage. The Inverter converts the DC energy from the modules to AC energy used in the house.
