What are Solar Decommissioning Costs and How to Calculate Them?

Solar panels are definitely a great technology that promises clean, renewable energy and a more sustainable future. Yet, unfortunately, as with any technology, they aren’t built to last forever.

Fast forward 20-25 years, and these solar panels may no longer be as efficient in generating electricity and even reaching obsolescence. Whether you are looking to upgrade to new arrays or move on to another technology, this is when you’ll need solar decommissioning. 

Yet, what does “solar panel decommissioning” actually mean?

Simply put, decommissioning is the responsible dismantling and disposal of a solar energy system reaching the end of its lifespan, typically around 20 to 25 years. The goal of decommissioning is to ensure the solar panel’s components don’t end up polluting our precious planet, whether by littering landfills, polluting the air after being incinerated, or other irresponsible ways. 

However, why should we care about this? Isn’t environmental sustainability the problem of the distant future? 

Not only are the dangers of environmental issues real and present, but decommissioning comes with a price tag—and not a small one. 

Depending on your array’s size and location, decommissioning your panels can cost thousands or even tens of thousands of dollars. Let’s be honest: nobody enjoys surprise financial burdens, especially down the line when your solar savings are supposed to be kicking in.

This is why understanding what exactly solar panel decommissioning will cost is important, and that’s what this article is for.

Understanding Solar Panel Decommissioning

As briefly discussed above, solar decommissioning is the process of carefully (and responsibly) dismantling and disposing of solar panels and associated equipment. 

By definition, solar decommissioning refers to the planned and systematic retirement of solar power systems, involving the safe removal and management of components at the end of their operational life. This process aims to ensure environmental sustainability and compliance with regulations.

Seemingly simple, decommissioning is actually a complex process with many nuances and intricacies. Let’s delve into them.

Common Reasons for Solar Decommissioning

Why do you need to decommission your solar panels? There are several common reasons why your panels might need to be decommissioned, each with its own implications:

1. Age and degradation: 

Solar panels, unfortunately, are subject to degradation and will lose efficiency. Over time, they will produce less energy from the sun and potentially become unreliable. The finite operational life of solar panels is around 25 to 30 years, triggering the decision to either decommission or upgrade the panel.

2. Technological obsolescence: 

Advancements in technology can render your older panels obsolete. Newer solar panels are naturally more reliable and efficient and may make upgrading your existing solar system more financially viable. 

In such cases, decommissioning the older setup may be a better choice for performance and efficiency reasons. 

3. System damage:

Even if your solar panels are still fairly “young” and shouldn’t have reached the end of their lifetime, accidents, weather events (i.e., hailstorms,) and other scenarios can damage your solar panels. 

When these damages make the panels unusable beyond repair, then decommissioning becomes a necessity.

4. Site repurposing: 

Changes in land use or urban development may necessitate the removal of existing solar installations to accommodate new projects. For example, renovations and roof replacements, as well as changes in property ownership, can require dismantling the solar systems, necessitating decommissioning. 

5. Economic considerations:

In some—albeit rare—-cases, changes in government policies/incentives and fluctuating energy prices might make solar technology less attractive (economics-wise.) This might motivate some solar system owners to decommission their panels.

6. Environmental concerns: 

Improperly disposed of panels or components pose environmental risks like lead contamination. Responsible decommissioning ensures safe and sustainable handling of materials.

Before initiating decommissioning, an environmental impact assessment is often conducted to identify potential ecological risks.This assessment guides the development of strategies to minimize environmental harm.

7. Regulatory Requirements and Environmental Considerations

Another important consideration when discussing solar panel decommissioning and its cost is the regulatory landscape. 

Solar decommissioning is subject to a myriad of regulations at local, state, and federal levels.

regulations may dictate proper disposal methods, recycling requirements, and site restoration measures.

Overview of the Solar Decommissioning Process

To understand the cost of solar decommissioning, it’s critical to first understand how the decommissioning process actually happens.

While the actual process may vary, a typical decommissioning process will involve the following steps: 

1. Site Assessment: Conducting a comprehensive assessment of the solar site to evaluate its current condition and identify potential challenges during decommissioning.
2. Equipment Dismantling: Systematic dismantling of solar panels, inverters, and other components, ensuring minimal damage and efficient extraction.
3. Waste Management: Categorize and manage waste streams, separating recyclable materials from non-recyclables.
4. Site Remediation: Implement measures to address soil and water contamination, restoring the site to its pre-installation state.
