Under a Power Purchase Agreement (PPA), Electron Green installs and maintains the solar system on your property at no cost to your business. Instead of purchasing the system outright, you simply buy the electricity it generates at a lower, fixed rate—helping you reduce energy bills without the capital investment. Here’s how it works:

• Zero Upfront Costs: You pay nothing for the design, installation, or equipment.
• Lower Energy Rates: You purchase solar energy at a predictable, competitive rate—lower than grid electricity prices.
• Long-Term Savings: With a typical PPA lasting 15-25 years, your business benefits from significant energy cost savings while avoiding maintenance responsibilities.
• Sustainability Benefits: By choosing solar, you reduce your carbon footprint and align your business with green initiatives.

For businesses that prefer ownership, financing options such as solar loans and leasing can also help spread the cost over time while reaping long-term savings.

By choosing the right financing model, you can achieve the benefits of clean energy without financial strain.

3. Initial Consultation: Your Solar Blueprint

The first step in any successful solar panel installation is the initial consultation. Think of this as the foundation of your solar journey. It’s where your installer takes the time to understand your business’s unique energy needs, goals, and property specifications.

This stage is more than just a conversation. Your installer will likely review your past energy bills to get a sense of your current usage patterns and determine how much energy your solar system should generate to meet your needs. They’ll also discuss the potential benefits of adding features like battery storage or smart monitoring systems for enhanced energy management.

At the end of the consultation, your installer will provide recommendations tailored to your goals, paving the way for a customised solar solution that meets your business’s needs.

4. Site Survey: Is Your Roof Solar-Ready?

After the initial consultation, the next step is the site survey—an essential part of the process that determines whether your property is suitable for a solar panel installation. This is where experts take a closer look at your site to identify opportunities and address potential challenges.

During the survey, the installer will evaluate several key factors to ensure your solar system operates at peak efficiency:

• Roof Size, Angle, and Material: The size of your roof determines how many solar panels can be installed, while the angle impacts how much sunlight the panels will capture. The material of your roof—whether it’s tile, metal, or flat—affects how the mounting systems will be secured.
• Sunlight Exposure and Shading: Installers will assess how much direct sunlight your roof receives throughout the day. Nearby buildings, trees, or other obstructions that cast shadows can reduce efficiency. Modern solar systems can often mitigate shading issues using technologies like microinverters or optimisers, but a clear understanding of these obstacles is critical.
• Structural Integrity: Solar panels are lightweight, but they still require a roof that can support their weight safely. The survey ensures your roof is in good condition and strong enough to hold the panels and mounting systems. If repairs or reinforcements are needed, the installer will inform you during this stage.

For businesses with unique or complex roof layouts—such as multiple levels, skylights, or limited space—bespoke solutions can be designed to maximise energy production. Ground-mounted systems or carport installations may also be viable alternatives if roof space is insufficient or unsuitable.

After the survey, you’ll receive a detailed report outlining the findings and next steps. This ensures you have a clear picture of your property’s solar potential and how any challenges will be addressed. With all the information in hand, your installer can move forward with designing a solar system tailored to your needs.

5. System Design: Tailored for Maximum Efficiency

Based on the survey results, your installer will design a system that’s customised for your property. This includes choosing the ideal panel type, deciding on the number of panels, and integrating optional features like battery storage. They’ll also determine the best inverter location and wiring plan to optimise performance.

6. Paperwork and Permissions: Leave It to the Experts

Solar installation involves its share of paperwork, but you’re in good hands. Your installer will handle the entire process, ensuring a smooth and compliant setup. This includes:

• Securing Prior Approval (if required) – Navigating local regulations to ensure your project meets all necessary requirements.
• Handling grid connection applications – Coordinating with your District Network Operator to safely connect your system to the grid.
• Managing compliance documentation – Ensuring your installation adheres to all relevant industry standards and regulations.
• Overseeing inspections and approvals – Liaising with authorities to finalise permits and certifications.

With all the technicalities taken care of, you can focus on running your business while your solar project progresses seamlessly.

7. Installation Day: Turning Plans into Reality

The big day has arrived! Here’s a detailed breakdown of what you can expect during your solar installation:

• Preparation: Your property will be carefully prepped for the installation process. This includes setting up scaffolding (if required), ensuring all safety measures are in place, and clearing the workspace to allow the team to operate efficiently. This will be discussed in a Kick-Off Meeting.
• Panel Installation: The solar panels are expertly mounted onto your roof or ground-mounted system. This involves securely fixing the racking and aligning the panels to maximise energy capture based on your property’s orientation and sun exposure.
• Electrical Work: The inverters, which convert solar energy into usable electricity, and any required monitoring systems are installed. These components are then carefully connected to your existing electrical infrastructure and grid to ensure seamless energy flow.
• System Testing: Once all components are in place, the installation team will thoroughly test the system. This includes checking the connections, ensuring panels are generating power, and confirming the monitoring systems are providing accurate data.
• Final Review and Handover: The team will walk you through the completed system, explaining how it works, what to monitor, and how to safely shut-on and off the system. A Handover Pack will also be provided containing information about the system.

Most commercial installations are completed within a few days, depending on the system size, property complexity, and weather conditions. By the end of the process, you’ll be on your way to generating clean, renewable energy with minimal disruption to your business operations.

8. Final Testing and System Activation

Before you can start harnessing solar energy, your installer will conduct thorough testing and commissioning to ensure the system is operating safely, efficiently, and as designed. Here’s what the final checks involve:

• Verifying all electrical connections: Each connection, from the panels to the inverter and grid, is carefully inspected to ensure it’s secure, compliant, and free of faults. This reduces any risk of electrical issues or power loss.
• Performance testing under various conditions: The system’s output will be tested to confirm it generates the expected amount of energy. This includes checks during different light levels or simulated conditions to ensure optimal performance.
• Activating monitoring tools: Your monitoring system will be set up and tested, giving you real-time access to data on energy generation, consumption, and overall system health. You’ll know exactly how much power your panels are producing at any time.
