We will utilize the rooftop on trains as the area of solar power panels where can be 20 even more solar panels with each panel capacity of 100 watts. So 100 x 20 = 1200 watts per carriage. The solar panels are intended to provide all the needs of the internal electricity such as lights, fans in both AC and non-AC, and television. This system will be able to reduce diesel consumption and carbon dioxide emissions by up to hundreds of tons per year.
