Policy formation involving manufacturer''s liability to inspire recycling of waste solar panels. R&D needs acceleration allowing researchers to resolve issues in PV module recycling. End-of-life (EOL) solar panels may become a source of hazardous waste although there are enormous benefits globally from the growth in solar power generation.
Solar Photovoltaic (SPV) modules occupy an important position in the value chain [1–5] (see Figure 9.1). Crystalline silicon (c-Si) is currently the preferred technology with a market share of about 85%. c-Si modules are made using crystalline silicon (Si) solar cells as the starting material. Several such cells are connected to make modules. The manufacturing process for c-Si
The construction of solar PV modules or solar PV arrays includes bypass diodes. The bypass diodes are used to prevent hot-damaging spots consequences of heating. The hotspot heating occurs if a malfunctioning solar cell or a bad cell is present among the proper solar cells in a module. During forward bias, the current flows through the short
The expected life of photovoltaic (PV) modules is 10–20 years as solar modules degrades over the course of time. This degradation is mainly due to the water ingress, ultra violet (UV) rays exposure and temperature stress. The module failure indicators include delamination of the module encapsulation, anti-reflection coating deterioration
The photovoltaic (PV) industry is expected to grow exponentially over the next five years with market experts anticipating the global market to more than double in size by 2014.

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. The basic components of these two configurations
Solar Photovoltaic Technology Basics . Solar cells, also called photovoltaic cells, convert sunlight directly into electricity. Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect. This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a

The hotspot failure mechanism is considered the most severe failure and leads to catastrophic consequences. It deteriorates all PV module components if undetected, and a PV module affected by an elevated level of hotspots cannot reverse the degradation and often requires replacement.
