The Parts, Piece by Piece

A ground-mounted array looks like a lot of equipment, but it's really a small team of simple parts. The foundation anchors it to the earth; the racking holds the panels at their angle; the panels turn sunlight into power; and the inverter turns that into the kind of power your house uses. Add disconnect switches for safety, the meter and your main panel to tie it into the house and grid, grounding as a safety net, an underground wiring run back to the house, and monitoring to keep an eye on it. The installer designs and sizes every piece — this is a licensed, permitted, professional install, never a do-it-yourself project, and no specs are guessed here. There's a printable 29-page version up top.

Common Questions

1 What are the main parts of a ground-mounted solar array?

The foundation (posts, piers, or ballast), the racking that holds the panels at their angle, the panels themselves, the inverter that converts their power, plus disconnect switches, the meter, grounding, an underground wiring run, and monitoring.

2 What does the inverter do?

Panels make direct-current (DC) power; your home runs on alternating current (AC). The inverter is the translator that changes one into the other, so the sunshine your panels catch can run your lights and appliances.

3 What's the difference between a string inverter and microinverters?

One uses a single larger inverter near the array; the other puts a small inverter behind each panel. Both are proven and do the same job — which suits your home is the installer's call, made to fit your site.

4 Will the array keep my power on during an outage?

Not on its own. A plain grid-tied array shuts off in an outage as a required safety feature. Only a battery keeps your essentials running — and your installer sizes it. Ask about one if outages concern you.

5 Do I have to understand all the parts to go solar?

No. The installer designs and sizes everything. Knowing the names simply helps you follow a proposal and ask good questions — which is exactly what makes you a confident customer.

6 Could I install any of this myself to save money?

No, and please don't try. Foundations, code wiring, grounding, and the utility connection are licensed, permitted work. Your role is to understand and evaluate it — the building is a professional's job.

Would You Rather I Just Help?

Got a proposal full of unfamiliar words? I'll sit down with you and translate every part into plain English — what it is, what it does, and why it's there — so you can read your own quote with confidence. I don't sell solar; I just help you understand it. $99 flat for a visit, 30-day come-back-free.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
