Can Solar Panels Be 100% Recycled? What Happens to Old Panels?
Blog Article
Introduction
Solar energy is being adopted increasingly rapidly in India, while cities like Mumbai have begun leading in sustainable energy solutions. Installations of residential solar panels in Mumbai, installations of commercial solar panels in Mumbai, and installations of industrial solar power solutions in Mumbai are fast becoming a major contributors to energy efficiency and cost-effectiveness. With solar technology undergoing constant change, one initial question arises: What happens to old solar panels? Are they recyclable at 100%? Let us explore solar panels' life, recycling methods, and how old panels are handled.
Life Expectancy of Solar Panels
Solar panels usually last around 25 to 30 years. They do not stop working when they reach this age; they simply lose the efficiency with which they previously worked and, thus, may produce less energy. Many panels will still function well beyond their warranty period but may not perform with the same output level as before.
There are many kinds of solar panels, lasting for different periods. Monocrystalline panels last for the longest time, while polycrystalline and thin-film panels' efficiency will degrade slightly faster. Regardless of the type, all solar panels will need to be replaced. In this case, the disposal and environmental concerns come into the picture.
Are Solar Panels Truly 100% Recyclable?
However, as far as recycling on solar panels is concerned, it is approximately 95% recyclable, not 100%. Up-to-date recycling techniques can recover and reuse almost all components - glass, silicon, aluminum, and wire. Let's see how different materials in solar panels are recycled:
Glass (75-80%) - recoverable and reusable for new panels or other glass products.
Silicon (10-15%)- can undergo purification and recycling for new photovoltaic cell fabrication.
Aluminum (6-8%)- effortless recycling into new frames or recycling into any other aluminum product.
Plastic and Remaining Materials (2-4%) - hard to recycle). Efforts are ongoing to improve this so that all plastics are usable.
It is not yet 100% recycled, but further solar panel recycling technology developments are closer to such a target.
What Happens to Old Panels?
They may go through different paths after the solar panels end their useful life.
Reuse and Repurposing-
Some panels are still functional, albeit at lower efficiencies, and can be used in smaller applications, such as powering streetlights and remote sensors or as backup energy storage.
Recycling Process-
Advanced recycling centers extract valuable resources from old panels. The recycling procedure consists of :
Dismantling-
The frames and junction boxes are removed.
Shredding-
The panels are made into powder.
Separation-
The separated materials, such as glass, silicon and metals, are purified for reuse.
Landfilling (Least Favored Option)-
If recycling is not an option, such as through lack of facilities or prohibitive costs, it is possible to dispose of it in landfills. This creates an environmental concern as these panels contain a small amount of hazardous materials.
A Manufacturer Take-Back Program-
Reputed solar panel companies are introducing take-back programs where customers can send back old panels for responsible recycling or disposal.
