How We Helped GEM Design a Custom Solar Solution for their Low-Speed Electric Vehicles

The Low-Speed Vehicles (LSVs) market continues to grow as individuals, families, college campuses, theme parks, and resorts opt for more efficient and environmentally conscious ways to get around. Increasingly these vehicles are even becoming the primary means of transportation.

To get the most value from an LSV, you need flexible means to charge and maintain your batteries.That’s where solar can make a difference.

Reefer Solar Panels Help Save More Diesel Than You Might Think

Refrigerated or frozen goods are kept at the proper temperature using transportation refrigeration units (TRUs) which allow for bulk transport but have a measurable effect on the amount of diesel a vehicle consumes. 


You might think you'd need a sizable solar panel to affect diesel consumption, but a small, cost-effective solar panel has a significant impact.

Today’s post dives into three key benefits solar panels provide to trailer refrigeration units (often referred to as reefers).


Solar panel benefits include: 

  1. Enabling trailer telematics
  2. Improving system reliability
  3. Reducing jump-start service calls

How To Solar Power Your Golf Car The Easy Way

Golf cars are a fixture of golf courses allowing players to finish more quickly and course owners to turn over more daily rounds. Increasingly golf cars are also an effective and popular way to get around communities where golf cars and other low-speed electric vehicles (LSEVs) are often the primary means of transportation.

While battery-powered golf cars have many advantages over gas-powered vehicles, they must be charged. To get the most value from a battery-powered golf car, you need a portable means of charging and maintaining those batteries. 

That’s where solar can make a difference.
