If you’re thinking about switching to solar, you’ve probably come across a few terms that sound more technical than they need to be. In this guide, we break down the solar terms you need to know, clearly and simply, so you can make confident, informed decisions about your energy future.

1. Solar Panel

The part of your system that sits on your roof and captures sunlight, converting it into direct current (DC) electricity. The more efficient the panel, the more sunlight it can convert.

2. Inverter

Solar panels generate DC electricity, but your home runs on alternating current (AC). The inverter is the middleman, it converts DC into usable AC energy.

3. Kilowatt (kW) and Kilowatt-Hour (kWh)

• kW refers to the capacity of your system — how much energy it can produce at a single moment.

• kWh is how much energy your system actually generates or uses over time. You’ll see this on your energy bill.

4. Battery Storage

Want to store your excess solar energy for nighttime use or blackouts? A home battery (like Tesla Powerwall) allows you to hold onto that extra energy rather than sending it back to the grid.

5. Grid-Connected vs Off-Grid

• Grid-connected systems are the most common — they’re tied to the main power grid and allow you to export excess energy.

• Off-grid systems operate independently, usually with battery backup, for remote homes or those wanting full energy independence.
