Sometimes the best solution for a homeowner with some sunny land is a ground-mounted solar system like this one in Apex. N.C. The home has an older roof with some shade that wasn’t a good option for solar, but this sunny plot in the back of the house was. The original plan was for 6.5 kW of solar, but after several revisions, Yes Solar installed 9.92 kW with 24 Silfab 310 watt solar panels at a 30-degree tilt and 75 feet of trenching. The owner is so pleased with the system he is already planning the expansion.
