On contrary, if you are using a more upscale food truck with several types of equipment ranging from an oven, large grills, a freezer, and a cooler.

Your energy requirements will vary greatly on what equipment you are using. So, it’s best to analyze your energy requirement before deciding to substitute your traditional electricity source with solar panels. Measure the number of kilowatt hours of electricity your truck is currently using and based on this number you will get a good estimate of how many solar panels to run a food truck. Your energy requirement also helps to determine how many solar panels do you need for a food truck.

2. Parking Space of Your Food Truck

One of the biggest mistakes food truck owners make is shifting to solar panels for food trucks even before considering where their truck is parked every day. It is one of the most important considerations. The most important factor in deciding whether you want to go solar or not depends on the location of your food truck. To go solar, your truck should be in a location where it is receiving sunlight throughout the time you are serving food. Think of it based on your truck’s angle and location. If your truck isn’t receiving adequate sunlight in its current location, consider moving to a new location or reconsider your idea of running a solar-powered truck.
