What Is Solar Racking and Balance of System Recycling?
Balance of system (BoS) refers to all components of a solar installation other than the panels and inverters — primarily the structural racking and mounting system, electrical infrastructure, and site equipment. In a decommissioning project, BoS represents significant material weight and value:
-
Racking and mounting: Aluminum and steel structural members, torque tubes, posts, ground anchors, and hardware. In utility-scale ground-mount systems, the racking structure can represent thousands of tonnes of steel and aluminum.
-
Electrical infrastructure: Copper and aluminum wiring, conduit, DC combiner boxes, AC disconnect equipment, junction boxes, and monitoring systems.
-
Site infrastructure: Transformer pads (concrete), access roads (if removable), and perimeter fencing components.
Unlike solar panels, most racking and BoS material is not regulated under RCRA — steel and aluminum are commodity metals with established recycling markets and minimal regulatory complexity. This makes BoS the easiest and most economically favorable recycling stream in most decommissioning projects.
Despite this, BoS is regularly omitted from decommissioning RFPs and recycling scopes — treated as a logistics problem rather than a material recovery opportunity. Blue Revive includes BoS recycling coordination in every decommissioning scope and provides material-specific documentation for each stream.
Our Racking and BoS Recycling Process
1. BoS Inventory and Material Assessment
Blue Revive reviews the racking system type (fixed-tilt, single-axis tracker, dual-axis), structural material (aluminum, steel, galvanized steel), electrical infrastructure scope, and hardware inventory. This determines material volumes, recycling pathway, and any special handling for galvanized or coated materials.
2. Coordination with Field Decommissioning Team
Racking is typically removed by the EPC or O&M team handling field decommissioning. Blue Revive coordinates the logistics side — staging, collection, and transport — with the field team's removal schedule.
3. Material Separation and Staging
Racking material should be separated by type at the site where practical — aluminum framing separate from steel torque tubes and hardware — to maximize recovery efficiency and commodity pricing. Blue Revive provides material separation guidance to field teams.
4. Collection and Transport
Steel and aluminum racking are heavy but compact when dismantled. Blue Revive coordinates flat-bed or open-bed freight for large racking volumes. Electrical components — wiring, conduit, combiner boxes — are packaged separately for electronics and metals recycling.
5. Metals Processing
Steel and aluminum are directed to metal recyclers. Copper wiring and aluminum conduit are directed to metals processors. Electronics components (combiner boxes, disconnect equipment, monitoring devices) are processed through Blue Revive's R2v3-certified electronics recycling chain.
Blue Revive provides weight tickets by material type, chain-of-custody records, and material disposition documentation as part of the project recycling record. For ESG reporting, BoS material weight and recovery data are included in the project-level ESG data export.
Why BoS Recycling Matters in Decommissioning RFPs
BoS recycling is frequently underweighted in decommissioning RFPs for three reasons: it is assumed to be handled by the EPC field team, its commodity value is not captured in recycling cost estimates, and its documentation is not specifically requested by lenders or ESG reviewers.
All three assumptions create problems:
-
EPCs may dispose of racking as scrap without documentation, which creates a gap in the project's material disposition record.
-
Uncontracted commodity recovery means the client bears recycling costs without capturing offset value from metal recovery.
-
ESG frameworks (GRI 306) require documentation of all waste streams by weight and disposition — BoS is a waste stream.
-
Blue Revive includes BoS in every decommissioning scope. Material-specific documentation is provided for each stream as a standard deliverable.
Frequently Asked Questions
Q: Is racking recycling required by regulation?
A: Not specifically for racking as a distinct category, but decommissioning obligations in land leases and interconnection agreements typically require complete system removal and site restoration. How the material is disposed of is then subject to RCRA and state solid waste rules. Documented recycling satisfies both the decommissioning obligation and ESG reporting requirements.
Q: Is galvanized steel harder to recycle?
A: Galvanized steel contains a zinc coating that some steel processors charge extra to handle. Blue Revive identifies galvanized material at assessment and routes it to processors equipped for galvanized inputs. Material separation at the site (aluminum vs. galvanized steel vs. carbon steel) improves economics.
Q: Can the copper wire value offset other recycling costs?
A: Copper wiring is typically the highest per-weight commodity value material in a BoS scope. For large systems with significant copper runs, commodity recovery can meaningfully offset panel or electronics recycling costs. Blue Revive provides transparent pricing with commodity offsets included.
Q: Do tracker systems require different handling than fixed-tilt racking?
A: Single-axis and dual-axis tracker systems contain motors, drives, and electronic control components in addition to the structural steel — these electronic components require R2v3-certified electronics recycling, not just metals processing. Blue Revive coordinates appropriate routing for tracker electronics.
Q: Can BoS recycling be scoped separately from panel recycling?
A: Yes, but integrating them is more efficient. Blue Revive can provide a BoS-only recycling engagement if panels are being handled separately, or include BoS as part of a full decommissioning recycling scope.
