Solar PV panels will probably lose efficiency over time, whereby the operational life is 20–30 years at least [7, 13, 16]. The International Renewable Energy Agency (IRENA) estimated that at the end of 2016, there were around 250,000 metric tonnes of solar panel waste globally . The solar panels contain lead (Pb), cadmium
The individual solar cells determine how efficient the solar panel and wider system is. Solar panel efficiency Efficiency is measured under standard test conditions (STC). Based on a cell temperature of 25 °C, solar irradiance of 1000W/m 2 and air mass of 1.5. Total solar panel efficiency is based on the maximum power rating (Watts) at STC
