Setting Up Your Overlanding Solar System

Overlanding has seen a surge in popularity among outdoor enthusiasts and adventure seekers alike. The urge to explore remote terrains, embark on epic journeys, and seek solitude amidst nature has led many to convert their vehicles into a home on wheels, embracing the self-reliant spirit of overlanding. Converting your vehicle into an overland rig equipped with a reliable solar power system is a game-changer, offering freedom, independence, and sustainability on the road. 


Solar power systems, once considered complex and expensive, are now becoming more accessible and affordable for adventurers seeking off-grid solutions. 


In a previous post, we explored the essential steps to convert your vehicle into a full-fledged overland adventure machine. The article highlighted the critical aspects, including vehicle selection, building sleeping and storage spaces, installing a kitchen, adding power sources, insulating the vehicle, setting up a water system, and optimizing the exterior for a comfortable and convenient camping experience. This comprehensive guide detailed each step crucial for a successful overlanding transformation. 

Today, we’re going to delve into the specifics of setting up a solar power system tailored for your overlanding vehicle. Solar energy is an eco-friendly and sustainable solution that can power your electronics, lighting, fridge, and more, allowing for extended off-grid adventures without compromising on comfort or convenience. Here, we'll break down the elements of an effective solar setup, drawing inspiration from successful installations and practical advice from seasoned overlanders. 

To start your solar power journey, selecting the right components is crucial. Solar panels are the heart of the system, transforming sunlight into electricity. Renogy, Goal Zero, and Jackery are reputable brands offering durable, efficient panels in various sizes and wattages suitable for overlanding needs. Below you’ll find a few important thoughts to considerations when choosing your solar panels: 

Power Requirements 

 Consider your power requirements when choosing solar panels. For instance, a larger fridge, multiple gadgets, or extensive lighting demands more power, necessitating higher-wattage panels. However, for modest energy needs, a single panel could suffice, charging smaller devices or maintaining a low-power system. 

Panel Placement 

 Efficient panel placement significantly impacts energy generation. Mounting panels on the roof, hood, or awnings maximize sun exposure during travel or camping. But remember, shadows from equipment, trees, or other obstructions can impede efficiency, so strategic placement is key. 


Most solar panels will require a charge controller, acting as a regulator between the panels and the batteries. This device prevents overcharging, maintains battery health, and optimizes power flow. MPPT (Maximum Power Point Tracking) or PWM (Pulse Width Modulation) controllers are common choices, each with distinct advantages based on system size and budget. 


Beyond panels and controllers, the energy generated must be stored in batteries for later use. Deep-cycle batteries like AGM, lithium, or gel cells are popular choices, offering durability and extended charge cycles for overlanding adventures. They retain charge longer, providing reliable power when sunlight isn't available. 


Connecting the solar panels, charge controller, and batteries requires wiring, connectors, and appropriate insulation. Ensuring compatibility between components and employing correct gauge wiring is crucial for safety and optimal performance. 


Installation of your solar power system demands precision and careful planning. Before beginning, it’s prudent to conceptualize the setup, determining the best location for panels, controllers, and batteries within your vehicle. Depending on your rig's design, consider roof, hood, or side placements for optimal sun exposure. 

Mounting solar panels securely is vital. For roof installations, durable brackets or racks specifically designed for your vehicle model ensure stability. Moreover, seal any drilled holes with appropriate sealants to prevent leaks and ensure weather resistance. 

It's important to pay close attention when routing cables from panels to the charge controller and then to the batteries. Employ waterproof and UV-resistant cables to maintain system integrity. Utilize conduit or cable tracks along the vehicle's interior to safeguard wires from damage and maintain a tidy setup.  

Ideally, the charge controller and batteries should be housed in a well-ventilated, easily accessible location, ensuring optimal airflow to prevent overheating. Additionally, adequate insulation and protection against extreme temperatures are essential for battery health. 

Configuration and system setup play a critical role. Setting voltage parameters on the charge controller and ensuring correct polarity connections are crucial for safe and efficient energy flow. Refer to manufacturer guidelines for specific settings and optimal operation of your solar system components. 

Other Considerations 

Regular maintenance ensures the longevity and efficient performance of your solar setup. Periodic inspection of connections, cables, and panels for wear, damage, or corrosion is imperative. Clean solar panels routinely to remove dust, debris, or grime that might hinder sunlight absorption. 

An understanding of your solar system's capabilities and limitations is essential for efficient energy management during overland trips. Monitoring power levels, knowing your energy consumption, and adjusting usage accordingly maximize the system's effectiveness.
