As solar technology evolves and systems age, decommissioning solar panels becomes a necessary part of responsible energy management. At Big Shine Energy, we are dedicated to not only helping you generate renewable energy but also ensuring the sustainable completion of your solar PV system’s lifecycle. Whether you are upgrading to a more efficient system, restoring your site, or removing non-operational equipment, decommissioning offers a valuable opportunity to modernize while simultaneously minimizing environmental impact.
Why Decommission a Solar PV System?
- End of Lifecycle – Most solar panels last 20–30 years. As efficiency declines, energy production decreases.
- Technological Advancements – Modern panels offer improved efficiency and performance, making upgrades beneficial.
- Structural Concerns – Roof-mounted systems may need removal for repairs or structural upgrades.
- Non-Operation – Systems inactive for over 12 months may no longer be cost-effective.
- Sustainability Goals – Newer systems align with environmental objectives by offering better recycling potential.
- Cost-Effectiveness – Replacing an aging system can be more economical than repairing it. Newer models require less maintenance and come with extended warranties.
According to DSIRE Insight, the U.S. will generate 1 million metric tons of end-of-life PV modules by 2030. Additionally, NREL projects that 27 gigawatts of commercial and utility-scale solar systems will be decommissioned by then. These figures highlight the importance of responsible disposal and recycling.
Key Steps in Solar Panel Decommissioning
Step 1: Assess System Performance
Before decommissioning, conduct a comprehensive operations and maintenance (O&M) assessment to determine which components can be salvaged or recycled. A professional O&M team should perform:
- Thermal Drone Scan – Detects overheating or damaged components.
- Visual Inspections – Identifies visible system anomalies.
- Electrical Equipment Thermal Imaging – Examines inverters and connections for failures.
- Continuity Testing – Confirms circuit integrity.
- Torque Testing – Ensures secure electrical connections.
- Performance Data Analysis – Evaluates inverter or Energy Management System (EMS) data to measure efficiency.
This assessment helps determine which parts can be repurposed. Some companies buy functional modules, while damaged ones may incur disposal fees.
Step 2: Notify the Utility Company
Inform your utility provider of the decommissioning plan to update facility records and prevent future project complications. Without proper updates, new installations might be classified as expansions, which could trigger unnecessary Supervisory Control and Data Acquisition (SCADA) requirements.
Step 3: Obtain Necessary Permits
Different states and municipalities have varying decommissioning policies. New Jersey and California enforce statewide regulations, while other locations may only require a decommissioning plan. Work with Authorities Having Jurisdiction (AHJ) to determine necessary permits, which may include:
- Demolition Permits – Required for structural removal.
- Electrical Permits – Needed to disconnect electrical components.
- Environmental Permits – Address hazardous materials and site restoration requirements.
- Waste Disposal Permits – Ensure compliance with transportation and disposal regulations.
- Land Restoration Plans – Necessary for ground-mounted systems.
- Surety Bonds & Reporting Documentation – Some jurisdictions require proof of proper decommissioning.
Step 4: System Removal, Recycling, and Site Restoration
Once all permits and approvals are in place, removal begins. This process includes:
- Panel Removal – Solar panels are carefully detached and assessed for reuse or recycling.
- Mounting System & Racking Dismantling – Hardware is disassembled, and the site is inspected for damage.
- Electrical Component Disconnection – Inverters, wiring, and electrical connections are safely removed.
To promote sustainable recycling, work with certified recyclers who responsibly handle decommissioned equipment. Responsible disposal practices include:
- Recycling Materials – Panels, racking, and electrical components are repurposed to minimize landfill waste.
- Environmental Benefits – Upgrading to efficient systems lowers your carbon footprint.
- Land Restoration – For ground-mounted systems, restoring the land supports local ecosystems or agricultural use.
Why Upgrade to a New Solar PV System?
If you are decommissioning an outdated solar system, consider upgrading to a newer, more efficient model to gain several benefits:
- Higher Energy Production – Modern solar panels generate more electricity even with smaller arrays.
- Lower Maintenance Costs – Newer models require less upkeep and offer extended warranties.
- Financial Incentives – Many governments provide rebates, tax credits, and grants for new solar installations.
- Grid Independence – Pairing a solar system with battery storage enhances energy resilience.
- Advanced Technology – AI-powered monitoring and optimization improve system performance.
