How Solar Works

Solar, explained simply.

No jargon. No diagrams you need an engineering degree to understand. Here's how residential solar actually works — for homeowners.

The basics, step by step

01

How solar panels create power

Solar panels capture sunlight and turn it into direct current (DC) electricity using photovoltaic cells.

02

How the inverter works

An inverter converts the DC electricity from the panels into alternating current (AC) — the type your home uses.

03

How solar powers the home

AC power flows from the inverter into your electrical panel and powers your lights, appliances, and outlets.

04

What happens at night

Your panels don't produce power at night, so your home draws electricity from the grid (or a battery if installed).

05

What happens on cloudy days

Panels still produce power on cloudy days — just at reduced output. System design accounts for variable weather.

06

How net metering may work

When your system produces more than you use, the extra power may be sent back to the grid for utility credits (where available).

07

Why system design matters

A good design matches your usage, roof orientation, shading, and local utility — that's where real savings come from.

08

Using more than you produce

If your home uses more electricity than your system generates, the difference comes from the grid as usual.
