Solar panel electrical hookup in Dallas

Solar installers size the array; the electrical connection to your house has its own rules. The code limits how much solar a panel can accept based on its bus rating and main breaker. Many older 100 and 125 amp panels in Dallas cannot accept a typical system without changes.

We evaluate the panel, then choose the simplest compliant option: a breaker on a panel with room, a derated main breaker, a supply-side connection, or a panel upgrade. We also add the disconnects, labels and grounding the inspector will check.

Solar Panel Electrical Hookup: signs to watch for

• A solar installer said your panel is too small
• You are planning solar and want the panel checked first
• Adding a battery to an existing solar system
• An inspection failed on the electrical connection
• Old solar equipment needs to be moved for a panel replacement

How we handle it

1. Check the panel bus rating, main breaker and available space
2. Choose a breaker connection, derate, supply-side tap or upgrade
3. Install disconnects, labels and grounding
4. Coordinate with your solar installer and the inspection

Check the panel before you sign

Ask your solar installer how the system connects to your panel and what changes it needs. If the quote assumes a panel upgrade or a derate, get that priced up front. We can check your panel and give you the electrical options in writing before you sign a solar contract.

What moves the price

• Panel bus rating and main breaker
• Derate, supply-side tap or upgrade
• Distance to the inverter and disconnects
