Driveway Gate Automation 101: Solar vs. Electric

A custom driveway gate provides security and curb appeal, but without automation, it is just a heavy manual barrier. The convenience of clicking a remote and watching your gate glide open is what truly transforms the entrance.

However, the most common question homeowners face during installation is: “Should I use AC (electric) power or Solar power?”

The answer depends on three factors: your geography, your gate usage, and the distance from your home to the entrance. Here is a breakdown to help you decide.

Option 1: AC Power (The “Grid” Option)

AC-powered gate openers are hardwired directly into your home’s electrical panel. This is often the default choice for suburban homes where the driveway gate is relatively close to the house or garage.

The Pros:

  • Unlimited Power: You never have to worry about cloudy days, winter sun angles, or a dead battery after a party where the gate opened 50 times.
  • Accessory Support: If you plan to add extensive accessories—like heated keypads, intercoms with cameras, or extensive loop detectors—AC power provides the consistent voltage these devices crave.

The Cons:

  • Trenching Costs: The biggest drawback is installation. You must dig a trench from your power source to the gate location to run the conduit. If you have a 500-foot driveway or have to cross paved areas/landscaping, the cost of trenching can actually exceed the cost of the gate opener itself.
  • Power Outages: While most modern AC openers have a battery backup, they are reliant on the grid.

Option 2: Solar Power (The “Off-Grid” Option)

Solar gate operators use a small photovoltaic panel to charge a battery housed inside the control box. The gate actually runs off the battery, not the sun directly. This is the gold standard for rural properties, farms, and large estates.

The Pros:

  • No Trenching Required: This is the primary selling point. If your gate is 1,000 feet from the nearest outlet, solar saves you thousands of dollars in electrical work and excavation.
  • Immune to Grid Failures: Because solar gates run on independent batteries, a neighborhood blackout won’t leave you stuck outside.
  • Tax Incentives: In some areas, solar gate installations qualify for federal green energy tax credits.

The Cons:

  • Sun Dependence: Solar requires clear access to the southern sky. If your entrance is heavily shaded by trees or located in a region with long, dark winters, you may struggle to keep the batteries charged.
  • Cycle Limits: Solar gates are limited by their battery capacity. If you run a commercial business or a busy ranch with 100+ vehicles entering a day, a standard solar setup might struggle to keep up.

Which is Right for You?

Choose AC Electric If:

  1. You are located less than 500 feet from a power source.
  2. You live in a heavily wooded area with little direct sunlight.
  3. You plan to install power-hungry accessories like telephone entry systems or magnetic locks.

Choose Solar If:

  1. You have a long driveway (farm/ranch application).
  2. You live in an area with at least 4-6 hours of direct sunlight daily, year round.
  3. Trenching would damage expensive landscaping or pavement.
  4. You want a system that operates independently of the power grid.

A Note on Heavy Gates

Regardless of how you power it, the physics of the gate matters most. A solar operator can easily move a heavy custom gate if the gate is well-balanced and the hinges are high-quality. However, if you are installing a large dual-swing system, you will need to ensure your solar panel wattage is scaled up to match the load.
