While planning a backyard solar project, a homeowner posted a basic but important question on Reddit: what is the right way to ground an eight-panel setup tied to a Delta Pro Ultra in the garage?
In a Reddit thread on r/solarDIY, the OP said the small backyard array would use eight panels and eight mounting units on pressure-treated 2x6s pinned into the ground with long nail spikes. They also said they already had solar cable and bare grounding wire for the project, adding that “The array will be about 100ft (give or take) from where the DPU units are.”
The homeowner made clear they were approaching the project carefully: “Please help me like I’m an idiot, because I am when it comes to all things electric and I want to get it right the first time.”
Several users said the system’s metal parts, including the panels and mounting hardware, should be properly bonded and grounded.
Going solar is one of the best ways to save money on home energy, and solar leases in particular can deliver hundreds of dollars in monthly savings without any upfront costs. Readers who want a simpler path can use EasyHome‘s free explorer tool to see pricing and savings from vetted installers in their area.
The project is a yard-based array, with a roughly 100-foot run back to the garage and a battery-backed home power setup that falls somewhere between portable backup and a more permanent installation.
The question reached beyond grounding a single panel. The homeowner was trying to figure out how to handle the array, mounting hardware, and individual panels across an outdoor structure set well away from the garage. Some materials were already on hand, including ground wire, while PVC conduit was still on the shopping list.
At this stage, the main step described in the thread was preparation. With eight panels, eight mounts, and a long cable run back to the garage, the homeowner wanted guidance before locking down the brackets and finishing the conduit route.
With energy prices through the roof, there’s never been a better time to go solar — and EasyHome can help you find the best prices from the best installers in your area.
EasyHome takes the guesswork and headaches out of energy upgrades by showing you estimated savings from a network of vetted local partners. To get started, just enter your ZIP and share a few details about your home — seeing your estimate is really that easy.
For readers still deciding whether to go DIY or hire a pro, EasyHome‘s free explorer tool is valuable because it lets users compare vetted installers, local pricing, and potential savings in one place instead of piecing together information from scattered forum comments. EasyHome can also help readers explore backup battery options, and pairing solar with a battery lets homeowners maximize savings and keep power when the grid goes down.
The practical checklist was to figure out how the panels, mounting hardware, array structure, wiring, and garage-side equipment connect before the system is energized. The goal was to complete one backyard installation safely and correctly.
The OP said, “I want to get it right the first time.”
