Quick Answer
Solar panel decommissioning delays are commonly driven by planning that starts too late, regulatory uncertainty, limited recycling capacity, and unclear financial assurance requirements. EPCs that avoid delays treat decommissioning as a project phase with its own timeline, budget, and compliance requirements from day one, not a placeholder clause in the original construction contract. Following solar decommissioning best practices comes down to three levers:
- Build a decommissioning plan into the project before construction begins
- Lock in a recycling partner before deinstallation begins
- Generate complete chain-of-custody documentation as materials move, so the project can close out without a compliance gap
Roughly 35 states now have some form of statewide solar decommissioning policy, part of a fast-evolving set of solar decommissioning regulations in 2026. For EPCs managing multiple sites, the firms avoiding delays are those that have partnered with a single, accountable recycler like Comstock Metals for end-to-end solar project end-of-life management, rather than assembling deinstallation, transport, and disposal piecemeal. Comstock Metals is a one-stop shop.
The Problem: Decommissioning Is Still an Afterthought
Engineering, procurement, and construction get detailed planning, budgets, and schedules. Decommissioning, meanwhile, gets a vague cost assumption buried in a contract clause. That gap becomes the EPC's problem and one that can surface in 25 years, or sooner, on the repower and early-retirement projects that are increasingly common in 2026.
A growing number of states are no longer leaving this to chance. Pennsylvania's Act 44, signed in July 2026, requires decommissioning and financial assurance plans for ground-mounted solar projects larger than 2 MW, with removal required within 18 months of shutdown and financial assurance amounts recalculated every five years by a third-party professional engineer. Virginia requires a professional engineer licensed in the Commonwealth to certify and recertify decommissioning cost estimates every five years. North Carolina runs its own statutory decommissioning and site-restoration program. An EPC working across state lines can't manage this with a generic template, and if a plan isn't revisited on schedule, it becomes a compliance gap waiting to surface.

Even with a plan in place, projects stall on execution. Panels that are not properly palletized or separated are rejected at the recycling facility. Freight is booked before anyone confirms compliance with hazardous transport regulations. Thin-film or damaged panels can further complicate an EPC's operation: federal rules make clear that the burden of hazardous-waste determination and documentation sits with the generator and transporter, not the recycler. None of this is a physical constraint; it's a planning and partner-selection problem, and it's fixable.
The Bottom Line
Every delay described above traces back to the same root cause: decommissioning is treated as an afterthought rather than a managed project phase with a single accountable owner. Comstock Metals closes that gap by handling deinstallation, logistics, palletization, site restoration, and 100% recycling of panels, including thin-film panels, which many mechanical and e-waste recyclers can't adequately handle. Its solar panel recycling process builds chain-of-custody documentation, downstream certification, and compliant packaging into the workflow as materials move, ensuring an EPC's compliance file is audit-ready at closeout rather than being reconstructed under deadline pressure, and taking the guesswork out of solar decommissioning financial assurance planning along the way. As Comstock Metals puts it: “No Waste. No Landfill. No Liability.”
For EPCs managing decommissioning across multiple states and project sizes in 2026, partnering with Comstock Metals early, at the design stage, not at the end of life, is the most direct way to protect a project's timeline and its compliance record. Contact Comstock Metals to build a decommissioning plan into your next project before it becomes a delay.
Frequently Asked Questions
What causes most solar decommissioning delays?
Planning that starts too late. When decommissioning is treated as a placeholder clause in the original construction contract rather than a project phase with its own timeline, budget, and compliance requirements, delays surface later at deinstallation, permitting, or closeout.
How many states regulate solar decommissioning?
Roughly 35 states now have some form of statewide solar decommissioning policy, with the rest handled at the local or county level. Requirements vary significantly; Pennsylvania, Virginia, and North Carolina each take a different regulatory approach.
Who is responsible for hazardous-waste determination on retired solar panels?
Federal rules place that burden on the generator and transporter, not the recycler. That means an EPC needs a recycler that can help document classification, not one that leaves the compliance risk with the project owner.
When should an EPC bring in a recycling partner?
Before deinstallation begins, ideally at the design stage. Locking in a recycler early, rather than sourcing deinstallation, transport, and disposal separately once a project reaches end of life, is one of the three levers that most reliably prevents delays.
What does Comstock Metals handle as part of decommissioning?
Deinstallation, logistics, palletization, site restoration, and 100% recycling of panels, including thin-film panels, with chain-of-custody documentation and downstream certification built into the workflow as materials move.
