  Power Transformer Power transformers are used in transmission network. Power transformers are rated above 200 MVA Power transformers works on high insulation level as voltage ranges above 33 kV i.e 33kV, 66kV, 110 kV, 200 kV, 400kV) Due to high insulation size of power transformers is large. Copper Losses in power transformers are less as it operates on 100% of loading 24 hours.  Efficiency of Power transformers is 99% . Distribution Transformer Distribution Transformer used to distribute electricity to consumer level. Distribution transformers are rated up to 200 MVA Distribution transformers works on consumer level below 33 kV voltage, doesn't require high insulation. Due to low insulation size of Distribution transformers is small compared to Power transformer. Copper Losses in Distribution transformers are more as load is not constant for 24 hours. Efficiency of Distribution Transformer is 60% to 75%. 

 The degradation of solar panels is not caused by a single phenomenon, but by several degradation factors affecting photovoltaic modules, but mainly due to the aging of the use time. Other causes of solar panel degradation include aging, light induced degradation (LID), potential induced degradation (PID) and backplane failure. 1- Aging caused by service time Aging is the main degradation factor affecting the operating life of PV modules. This degradation is due to the direct consequence of years of exposure of modules to rainfall, snowfall, extreme temperatures, hail, dust and other external factors. When photovoltaic modules are exposed to the above external factors, they will begin to decay and reduce their efficiency over time. This is due to the corrosion of the solar panel frame, the delamination of glass and backplane and the loss of the performance of photovoltaic materials, all of which lead to the degradation of photovoltaic modules by 0.5% per year on average. The solar ...
