Maximize the use of your liftgate

Research shows that most road calls are related to power failures. The WALTCO Solar charging solution resolves this problem by generating power through solar panels on the roof of your truck or trailer and storing it in your liftgate battery.

Stay charged

  • Charging source independent of tractor


Maximize the use of your liftgate while protecting the range of your electric vehicle.

  • Preserve your vehicle range when using your liftgate
  • Provide additional power to support auxiliary equipment

Why choose solar power?

The sun’s power is unlimited, making it our most reliable energy source. It’s clean, cost-effective, and infinitely renewable. More importantly, with solar power your liftgate battery never dies. It keeps charging even when your vehicle is stationary, and never overcharges. All this means you can put an end to stops caused by power problems and maximize the uptime of your fleet.table-solar-zepro.png

Are solar panels available as retrofit kits?

Yes – the panels are quick and easy to install as retrofit.

Should liftgate batteries be replaced when installing a solar panel retrofit kit?

We recommend installing fresh batteries with the solar charging solution.

How long does it take to install the WALTCO Solar charging solution?

Installation takes approximately two hours.

Does the vehicle auxiliary battery system still get wired to the solar charging system?

Yes, solar panels assist with maintaining batteries’ optimal charge level, between 12.7 and 14.4 volts, but the battery should still be charged off the truck alternator in addition to the solar panels.

Is there an option for solar charging a pallet jack?

The solar DCS kit includes a controller and relay logic to supply a 12-volt system for liftgate charging as well as a 24-volt system for pallet jack charging.

Does the WALTCO Solar charging solution carry a warranty?

The WALTCO Solar charging solution carries a 5 year warranty.

What about snow, ice, and dirt?

Because ice is translucent, it restricts but doesn’t prevent solar charging. Enough snow will block out the sun and prevent charging. However, as snow must generally be removed from highway vehicles, this issue is easily avoided. As for dirt, the solar panels are easy to clean, with rain doing some of the work for you. The panels’ placement also makes it unlikely that accumulated dirt will disrupt charging.

Will I get enough sun to charge my battery?

While the photovoltaic power potential (PVOUT) does vary between regions, the difference is smaller than you may think. Check the Global Solar Atlas to find the average PVOUT in your region.
