ANALYSIS AND DESIGN OF BLOCKS USING END OF LIFE (EOL) SOLAR PANEL

Abstract

The rapid expansion of solar energy systems has led to a growing concern regarding the disposal of end-of-life (EoL) solar panels. This study explores
a sustainable approach for recycling waste glass and silica powder recovered from EoL photovoltaic (PV) modules for use in the production of concrete blocks.
The glass and silica-rich materials, primarily derived from the encapsulant and glass layers of decommissioned solar panels, were processed and integrated as
partial replacements for conventional fine aggregates and cement. The mechanical properties of concrete blocks were evaluated through compressive strength
testing. The compressive strength of M25 grade concrete with a 12% partial replacement of fine aggregate with glass was evaluated at 7, 14, and 28 days of curing.
The results showed a compressive strength of 16.113 N/mm² at 7 days, 32.24 N/mm² at 14 days, and 36.223 N/mm² at 28 days. While the 28-day strength surpassed
the target of 25 N/mm² for M25 concrete This research contributes to sustainable waste management strategies and highlights the potential of EoL solar panels as
a valuable secondary resource in construction material production. The durability and environmental impact are the further scope of research.
