A thorough analysis of solar photovoltaic technologies, mathematical modeling of PV modules, maximum power point tracking, performance evaluation based on power and energy, overall performance indices, degradation and failure modes in PV panels, and a method for degradation analysis is presented [21].
The cumulative installed capacity of PV panels is converted into number of panels by dividing the capacity (in MW) by the average power of the panel (300 Wp). The resulting number is then multiplied by the market share of crystalline silicon, which is 97 % [2], and then multiplied by the average mass of the panels (25 kg) to convert it into mass units [7] .

The solar panel would become less efficient once the temperature rises. This means the output of the solar panel would decrease, thus produces less electricity [102]. Some of these heating defects can cause solar cells to break down. Thermal imaging is one of the best solutions to find these problems before failure [56].

Degradation mechanisms may involve either a gradual reduction in the output power of a PV module over time or an overall reduction in power due to failure of an individual solar cell in the module.
