Hello! This is Nishida Service. In recent years, we have seen a rapid increase in inquiries regarding solar panels.
Starting from April 2025, Tokyo will introduce a new system requiring the installation of solar power systems for new residential buildings. This policy is expected to lead to a continued rise in the installation of solar panels.
However, one aspect that is often overlooked is what to do when these panels are no longer needed—specifically, how to safely remove, recover, and dispose of them.
Solar panels are not treated as general bulky waste due to their complex composition. They are made from composite materials, such as glass and metal, and each panel weighs approximately 20 kilograms. Additionally, they are fragile and require careful handling to prevent breakage.
As a result, many local municipalities do not include solar panels in their waste collection services, and residents often find it difficult to dispose of them as oversized waste. This can lead to situations where people are unsure of how to properly dispose of or recycle their solar panels.
In reality, the options for disposing of solar panels are limited. While it is possible to contact the installation companies or manufacturers for assistance, there are many cases—especially with panels made in China—where support is unavailable or the manufacturer cannot be reached.
Additionally, when treating solar panels as industrial waste, it is necessary to entrust the processing to a licensed waste management company.
Given these circumstances, hiring a specialized contractor who can handle everything from removal and transportation to collection and disposal has become the most practical and popular choice.
Handling solar panels improperly can pose significant safety hazards. Hiring unlicensed contractors, improper disposal such as illegal dumping, or attempting to forcibly remove panels from roofs can lead to accidents and legal issues.
Especially for panels installed on roofs, there are risks of falling or electric shock, and damage can potentially affect the surrounding area. Therefore, it is essential to rely on professionals with the specialized knowledge and experience to ensure safe and proper handling.
Solar panels also have a finite lifespan. Typically, they last around 20 to 30 years; however, they do not suddenly become unusable. Over time, their energy generation efficiency gradually declines.
Additionally, the lifespan of the power conditioner is approximately 10 to 15 years. Factors such as the end of the feed-in tariff period and decreasing power output often lead many to consider removal or replacement within roughly 10 to 15 years.
Even unused solar panels cannot be considered entirely safe. Over time, they can deteriorate, leading to damage or falling due to loose mounting. Issues with wiring can also arise, and in some cases, these problems may cause leaks.
In other words, even panels that are no longer in use can pose safety hazards. If left unattended, the situation can worsen, making repairs more difficult. Therefore, it is important to seek professional advice promptly to address these concerns early.
Nishida Service provides comprehensive support for the removal, transportation, collection, and proper disposal of solar panels. We are flexible in responding to inquiries such as “I want to remove panels still attached to the roof,” “I want to dispose of the removed panels,” or “Manufacturers are unable or unwilling to assist.” We prioritize safety and ensure thorough work tailored to each site’s specific conditions.
As solar panels continue to become more widespread, the timing for aging, replacement, removal, and disposal will inevitably arrive. It is expected that the number of people facing disposal issues will increase significantly in the future.
Solar panels are often more challenging to dispose of than they are to install. Therefore, choosing a reputable and experienced contractor is crucial.
At Nishida Service, we draw on years of on-site experience to carefully address each individual inquiry. If you are facing difficulties with the removal, recovery, or disposal of solar panels, please do not hesitate to contact us for assistance.
