Apart from the solar panels, there are a number of components that make the solar system to be installed at factories and industries. Solar Inverters are the most important component after the solar panels which need to be properly selected and installed for rooftop solar systems. Most industries in Delhi and NCR (Faridabad, Kundali, Panipat, Sonipat, Ghaziabad, Manesar, Noida, Neemrana etc) have opted for strong brand names for the inverters that would include ABB, Huawei, SMA, Delta, Waaree etc. The Inverters are available with a warranty of 5 years though the extended warranty of another 5 years can be available by paying a bit extra. Quality of Inverters matter significantly in generating higher power from the same level of solar generation provided by the Solar panels. More number of MPPTs (Maximum Power Point Tracker) generally help to increase the reliability of the solar system and provide better generation. The structure for mounting the Solar Panels is an important part of the system. The strength of the structure should be such that they can bear a wind speed of 180 kms per hour. Typically, the structure should be designed and tested on the design software like STAAD.PRO to check their suitability for the given height and weight. As the height of structure increases, the wind pressure increases. Recently in places like Alwar, many solar panels flew away due to poor quality of structure. Consumers should be careful in selecting the structure as the flying panels can not only damage the system but also can cause serious accidents. DC cables should be used for interconnecting the solar panels. Practices have been noticed where in the vendors tend to connect the panels by the AC cables which increases the generation losses. AC cables are cheaper and can help to reduce the capital cost in short term but will be expensive due to mounting losses. Ideally the DC cables should only be utilized to connect the solar panels to the Inverters. AC cables of right size should be used to connect the Inverters to the AC junction boxes or the LT Panel of Discom. Sizing of the cable is important to reduce the losses. Earthing of the system is important for the safe operations. Earthing strip and wires need to be connected to all the key electrical components. Lightening Arrestors (LA) are required to safeguard the system against any weather lightening and should be installed based on the system size. Remote monitoring of the generation should be provided to continuously check the health of system. Water piping system should ideally be designed to provide the water supply for periodic cleaning of the panels which will help to increase the generation.
