5 Things to look for When Purchasing Your First RV Solar System

5 Essential Tips When Buying Your First RV Solar System

Investing in an RV solar system enhances your travel freedom, reduces costs, and ensures reliable power wherever your adventures take you. However, choosing the right system can be daunting. To help you make a confident and informed decision, here are five essential tips you should consider before purchasing your first RV solar system.

1. Choose a Reputable Supplier

Your solar system is an investment, so selecting the right supplier is critical. Begin your research by reading online reviews from platforms such as Google and Facebook to understand previous customers' experiences. Look for a company that has been established for several years, offers comprehensive customer support (both before and after your purchase), and has products specifically designed for Australian conditions. While price is important, quality and reliable service will ensure your RV solar system lasts for many years without unexpected issues.

2. Accurately Calculate Your Energy Needs

One of the biggest mistakes RV owners make is inaccurately estimating their energy requirements. Underestimating can lead to frequent power outages, while overestimating results in unnecessary costs. To avoid these pitfalls:

• Measure Precisely: Use a shunt-based battery monitor to accurately measure your real energy usage. Smart shunts provide exact energy consumption data, helping you plan correctly from the start.
• Seek Professional Advice: Alternatively, consider a free consultation with one of our Australian-based technical specialists, who can precisely define your load and recommend a customised solar solution tailored specifically to your RV’s requirements.

3. Select the Right Battery Technology

Your choice of battery is a crucial factor determining your solar system’s performance, reliability, and lifespan. Avoid typical sealed lead-acid batteries commonly sold in general retail stores, as they offer limited lifespan and performance.

Instead, consider these superior battery technologies:

• AGM Batteries: Maintenance-free, with better performance and longer lifespan than standard lead-acid batteries.
• Lithium-ion (LiFePO4) Batteries: Offering unmatched performance, longevity, and lighter weight, lithium batteries have a higher initial investment but significantly lower long-term costs. Check our range of premium lithium-ion batteries here.

4. Maximise Efficiency by Correctly Positioning Your Solar Panels

Solar panel positioning has a significant impact on your system's effectiveness. Even slight shading can drastically decrease your panels' energy output—up to 90% reduction in some cases. To maximise energy production:

• Ensure panels are placed in full sunlight with no shadows from nearby trees, antennas, or roof accessories.
• Prioritise unshaded locations—even if this slightly compromises perfect orientation—as shaded panels will always yield significantly less power.
• Understand your panel wiring setup, as shading on a single panel can reduce the efficiency of connected panels.

5. Choose a High-Quality Solar Charge Controller

A solar charge controller plays a critical role in managing power flow between your solar panels and batteries, safeguarding battery life and ensuring consistent energy efficiency. While some installers might use cheaper controllers to save costs, investing in a high-quality solar controller provides long-term reliability and performance.

Look for controllers that:

• Feature robust designs with substantial heat sinks for better thermal management.
• Unless in a clean environment, avoid models with cooling fans, which can be prone to mechanical failure.
• Come from reputable brands like Victron Energy, known for exceptional reliability and proven customer satisfaction.

Although premium solar controllers might be more expensive upfront, their durability, performance, and longevity make them a cost-effective choice in the long run.

Set Yourself Up for Limitless Adventures!

By carefully following these five essential tips—selecting a reputable supplier, accurately calculating your energy needs, choosing advanced battery technology, optimally positioning your solar panels, and investing in a quality solar charge controller—you’re setting yourself up for endless off-grid adventures. Embrace the freedom, confidence, and reliability that come with a thoughtfully designed RV solar system, and start exploring the road less travelled with complete peace of mind!
