In the trucking industry, fuel costs are a big part of how much it takes to drive a truck in North America. In the last ten years, fuel prices have experienced significant fluctuations, ranging from relatively low prices to peaks of high costs, impacting the operational expenses of trucking companies and the profitability of drivers. Moreover, the United States Environmental Protection Agency (US EPA) and the National Highway Traffic Safety Administration (NHTSA) have set regulations for greenhouse gas emissions on commercial vehicles, extending until 2030. These regulations push manufacturers to create and sell technologies that can enhance efficiency. As a result, fleets, manufacturers, and others are focusing on improving the efficiency of over-the-road trucks and trailers.

Luckily, technologies are available now that can help trucks use less fuel. But, even though these technologies are out there, not many companies are using them yet. One reason for this is that there isn't enough information about how well these technologies work and if they're worth the investment. One of these technologies is solar panels.

What are solar panels?

Solar panels are devices placed on a truck's roof or other parts that convert sunlight into electricity. They have many cells made of special materials that turn sunlight into electrical power. This electricity can run different things in the truck, like lights, refrigerators, or heaters. Sometimes, these can also be portable solar panels with batteries to store extra electricity when the sun isn't out.

Benefits of using the best solar panels

Solar panels have become increasingly popular in recent years due to their potential to reduce fuel consumption, lower operational costs, and minimize environmental impact. Trucking companies are turning to portable solar panels as a sustainable solution for powering their vehicles and reducing their carbon footprint.

The best solar panels offer several benefits for commercial heavy-hauling trucks:

1. Reduced fuel consumption: By using solar energy to power systems such as lights, refrigerators, and HVAC units, trucks can rely less on traditional fuel sources. This reduction in fuel consumption leads to lower operational costs for trucking companies, making solar panels a cost-effective solution in the long run.

2. Environmental sustainability: The best solar panels provide a renewable energy source that helps reduce truck greenhouse gas emissions. By minimizing reliance on fossil fuels, solar-powered trucks contribute to cleaner air and help combat climate change.

3. Extended battery life: Regular or portable solar panels help keep the truck's batteries charged, preventing them from fully discharging and prolonging their lifespan. This reduces the need for frequent battery replacements and lowers maintenance costs for trucking fleets.

4. Enhanced energy independence: Trucks equipped with the best solar panels can access renewable energy sources, reducing dependence on external power sources during stops. This increased energy independence allows truckers to operate more efficiently and autonomously, especially during rest breaks or layovers.

Despite these benefits, there are also challenges associated with adopting solar panels for commercial trucks. 

Challenges for installing solar panels to your trucks

Trucks face unique challenges when integrating regular or portable solar panels into their design and operation. These challenges stem from limited space, initial cost, durability, maintenance requirements, and efficiency in varying conditions.

1. Limited space: Trucks don't have much room for solar panels. They are big, and there's not a lot of space for solar panels. So, installing them requires careful planning to get the most power from the little space available. People who design trucks need to put the solar panels in the right places to get as much sunlight as possible without getting in the way of other truck parts or making the truck less aerodynamic. This is where portable solar panels can also come in handy.

2. Initial cost: The best solar panels can help save money on fuel and maintenance in the long run, but they can cost a lot to install initially. Trucking companies need to consider whether it's worth spending the money now to save money later. Even though the cost of solar panels has gone down in recent years, it's still something trucking companies need to consider when deciding if they want to use solar power.

3. Durability and maintenance: Trucks have to deal with tough conditions like bad roads, hot and cold weather, and lots of shaking. Solar panels on trucks have to deal with all that, too. So, it's important to make sure that the solar panels are strong and reliable. People need to check the solar panels regularly to make sure they're working well and fix any problems quickly so the truck doesn't have to stop working.

4. Efficiency in varying conditions: Solar panels work best when the weather is good, it's daytime, and they're facing the sun. But sometimes it's cloudy or the sun isn't shining as bright. When this happens, solar panels don't make as much energy. Trucking companies need to find ways to make sure the solar panels work well in all kinds of weather. They might tilt the panels or change their direction to get the most sunlight. They might also use batteries to store extra energy for when it's cloudy or dark.

Even though there are challenges, using solar panels on big trucks has a lot of benefits. It can help save money on fuel, make trucks cheaper to run, and help the environment. As technology gets better and solar panels become more efficient, more trucking companies are likely to start using solar power to run their trucks. This will make the trucking industry more sustainable and better for the environment.

Best practices to install solar panels for your fleet 

When deciding whether to use solar panels on your trucks, there are several things to think about to make sure it's a good idea. You need to consider how much energy the panels will produce, how much fuel they'll save, how long they'll last, how they affect battery life, and how much energy your fleet uses overall.
