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.

Solar Panels Help Maintain Vehicle & Equipment Batteries

Do you own a fleet of construction vehicles, delivery trucks, battery-powered trailers, a boat that sits outside in the off-season, or a vintage car you don’t often drive that sits for extended periods but needs to be ready to go when you turn the key?

Today’s post outlines current solutions to ensure your batteries don’t die when sitting for long periods, their drawbacks, and how a relatively small solar panel can significantly affect battery lifetime and overall maintenance.

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.
