They are generally constructed of GI or painted MS structure wherein the cost of MS painted structure is generally higher than GI but they can be customized for each roof and upto extreme heights.

4. Junction Boxes: There are safety devices which are installed on both the sides of the inverter, ie AC and DC side. This ensures that all the components are isolated from each other incase of any faults. Ensure that the MCB is installed as per your connected load, generally for a 3kW solar plant 16A MCB is used. Along with this, SPD’s and fuses are present in the junction boxes. One most important and ignored component in junction boxes are the boxes itself. The solar panels has a warrantied life of about 25 years and the junction boxes would be in the full wrath of the weather all this time. The outer box needs to be of good quality to ensure that the components installed inside are protected in all seasons.
