Ground-Mount Solar With Backup Power Supply in Central Texas
April 12, 2019
A homeowner on Lake Travis, west of Austin, needed a solar backup power system on his property. At solar panel company Freedom Solar built and connected an attractive ground-mount solar panel array in a landscape design. Plus, we added a backup power supply with an off-grid component.
Residential Ground-Mount Solar
First, we made the array of 36 SunPower E-Series 327-watt DC solar panels, arranged four panels high and nine panels long. Then, we directed it at a 205-degree azimuth and a 15-degree pitch. There are three circuits of 12, wired in groups of six in a series, with two groups in parallel to make 12 for each circuit.
The array is 300 feet from the equipment room, which houses the inverters, power distribution panel (PDP) and solar battery storage. Power backup for the home consists of a solar battery backup and a home backup generator. We installed the Iron Edison Lithium Iron Phosphate 48-volt battery.
The generator was on-site when we began.

The PDP ties into the grid as well as the home battery and the backup generator. A separate “emergency panel” is directly fed from the off-grid side of this system. The solar panels, battery or generator can power this panel, but it’s not grid-tied.
The ground-mount solar power system will offset almost half the homeowner’s annual electricity usage. In fact, it’ll save him more than $30,000 over the solar panels’ lifetime.
Having a home battery backup system that includes a backup generator and a solar battery ensures a robust, redundant power supply during emergency outages.
