Five Things You Should Check Before Your Solar Installers Leave

Investing in solar energy is a transformative step toward reducing electricity bills, cutting your carbon footprint, and achieving energy independence. However, ensuring your solar system functions optimally doesn’t end with installation. Before your solar installers pack up and leave, it’s crucial to verify everything has been done correctly.

Taking the time to check these critical factors ensures a smooth transition to solar power and avoids potential issues that could impact your system's efficiency or lifespan. Here's what you need to know.

Why These Checks Matter

The renewable energy sector has experienced a significant boom in recent years, with more homeowners recognising the benefits of solar energy. A residential solar system is a long-term investment in sustainability and financial savings. However, issues such as improper installation, missing components, or incomplete setup can compromise your system's effectiveness.

Addressing these potential problems immediately after installation ensures:

• Maximized energy efficiency
• Reduced need for future repairs
• A seamless experience transitioning to solar energy

By conducting these checks before your installers leave, you’ll have peace of mind knowing your system is ready to deliver clean, renewable energy for decades.

1. Confirm the Installation is Complete

The first step is to ensure the physical installation is done correctly. A solar energy system is more than just panels—it involves various components working together to generate and store energy efficiently.

Visually Inspect the System

Take a walk around your property to examine the installation. Check that:

• The solar panels are securely mounted and free of visible damage
• Wiring is neatly arranged, with no loose cables or exposed connections
• Mounting systems are stable and correctly installed

If you have a rooftop system, ask your installers to confirm that the roof’s integrity has been maintained. Any improperly sealed mounting points could lead to water leaks or structural damage. For ground-mounted systems, ensure the anchoring is robust enough to withstand high winds or severe weather.

Ensure All Components Are Installed

Your solar solutions should include all promised components. These typically include:

• Inverter: Converts solar energy into usable electricity
• Monitoring system: Tracks the system’s performance
• Solar battery (if applicable): Stores excess energy for use during low-sunlight periods

Missing or improperly installed components can significantly reduce your system’s efficiency. Confirm with your installers that everything is in place and operational.

2. Verify System Performance

Even a visually perfect installation can have underlying issues that affect functionality. Verifying performance ensures your system delivers on its promises.

Run a Functional Test‍

Ask your installers to demonstrate the system in action. The inverter and monitoring system should be working correctly, providing real-time data on your energy production. If your system includes advanced features, such as dual-axis tracking, ensure they are properly calibrated to maximise sun exposure.

Check Energy Output‍

Compare the actual energy output to the estimated figures provided during your consultation. While weather and seasonal variations can cause minor differences, significant discrepancies could indicate installation issues or faulty equipment. Address these concerns with your installers before they leave.

Assess Solar System Size

Your system size plays a critical role in its performance. Ensure the installed system matches your energy needs as discussed during the initial planning stages. A mismatch in size can lead to either insufficient energy production or overproduction without proper storage capacity.

3. Ensure Safety Protocols Are Met

Safety is a paramount concern when dealing with electricity. Proper installation minimises risks and ensures your solar system operates efficiently.

Inspect Wiring and Connections‍

Faulty wiring can pose fire hazards or reduce your system’s lifespan. Ask your installers to walk you through the electrical setup. Look for:

• Proper grounding
• Secure and neatly arranged cables
• Weatherproofing for outdoor components

If you’re unsure about any aspect of the electrical work, ask your installer for clarification or additional documentation.

Roof Integrity Check

If your panels are installed on your roof, ensure that the mounting points are sealed and waterproofed. Poorly sealed mounting hardware can lead to roof leaks, which may cause extensive damage over time.

4. Obtain Documentation and Warranties

Solar energy systems are a significant investment. Proper documentation and warranties protect you from unexpected costs or system failures in the future.

Collect System Documentation‍

Before the installers leave, request all relevant paperwork, including:

• A detailed system design and layout
• Solar accreditation (Australia-specific certifications ensuring compliance with industry standards)
• Warranty details for the panels, inverter, and solar batteries
• User manuals for your monitoring system and other components

This information is essential for troubleshooting, future upgrades, or warranty claims.

Understand Warranty Coverage‍

Solar panels often come with a 25-year warranty, but other components like inverters or batteries may have shorter coverage periods. Familiarize yourself with the terms and conditions, and ask your installer for maintenance recommendations to keep your system running smoothly.

5. Understand Your Monitoring System

A monitoring system is your window into the daily performance of your solar energy setup. It allows you to track energy production, detect faults, and optimize efficiency.

Learn to Track Performance‍

Your installers should provide a detailed walkthrough of your monitoring system. Whether it’s an app or a web portal, you should know how to:

• Check energy production in real-time
• Compare daily, monthly, and yearly performance trends
• Identify potential underperformance or errors

Set Up Alerts‍

Many monitoring systems offer alert features for faults or significant drops in performance. Ensure these are enabled and understand how to respond to notifications. Quick action can prevent minor issues from becoming costly problems.

What About Solar Batteries?

If your system includes solar batteries, take extra time to understand their functionality. Batteries are essential for energy storage, allowing you to use solar power during cloudy days or at night.

Ask your installers to explain:

• The battery’s storage capacity and discharge rates
• How to monitor its health and lifespan
• Maintenance tips for optimal performance

Solar batteries are a valuable addition to residential solar systems, enhancing energy independence and reducing reliance on the grid.

Final Thoughts: Diligence Ensures Success

Switching to solar energy is a commitment to sustainability and self-sufficiency. By thoroughly inspecting your system before your solar installers leave, you’re safeguarding your investment and ensuring years of efficient energy production.

Take the time to:

• Confirm all components are installed and working correctly
• Verify system performance matches the promised specifications
• Ensure safety protocols are met
• Obtain comprehensive documentation and warranties
• Learn how to monitor your system effectively

These steps set the foundation for a seamless solar experience, helping you reduce electricity bills and contribute to a greener future.

Investing in solar energy isn’t just about saving money—it’s about embracing innovation in the renewable energy sector. With the right checks and a proactive approach, you can enjoy all the benefits of solar power while ensuring your system operates at peak efficiency.
