collected and analyzed, to make sure that it is a success in the long run. Whether it is roof top installation or large MW units, the engineering backbone and approach needs to be standardized. At the moment, a large gap exists between the volumes of data being generated and recorded, to it being interpreted in a form that is useful for companies, government and clients alike. The potential for companies and organizations that can translate this data is immense, as they could be dictating future policy formation from their learning. For kW and captive consumption projects, load pattern and solar energy generation pattern needs to be carefully analysed before deciding on the kind of system to be installed. Also, the importance of Bi- Directional meter or reverse power flow panel is sometimes overlooked to keep the cost low. This has given rise to hybrid installations to show inflated bills. Most PV modules come with a warranted life of 25 years. But a hasty approach and lack of quality engineering towards the execution of the project results in failure of the power plant at a much earlier time. Many projects adopt an electrical configuration that is quicker and easier to install. The considerations for preventive and operational maintenance are difficult after this. For example, developers have started using a string combiner box instead of a string monitoring box and with project sizes increasing to tens of MWs, these turn out to be a nuisance in case of a fault detection where the technician is burdened with the task of finding a needle in the haystack. Lack of established maintenance training institutions with shortage of experienced and well-informed professionals leave operations unobserved due to lack of important data necessary to guide them in case of a technical slag. The fate of the entire project lies on the common sense of the technician. Well trained and knowledgeable O&M service providers will play a very important role, especially to contribute to the rise in performance of plant operations. These hurdles have led many investors to face huge losses from merely ignoring or overlooking the need for quality material and skill. It is wiser to invest heavily and face profits in the long run than to cut short the budget and invest a smaller amount into an entity that will soon be dead. The mindset of the investors and concerned professionals need to change for seamless growth of solar power production. This will ensure financial benefits in the future. Unless this happens, issues that are persistent in the industry will continue and probably even rise without a solution. With government laying ambitious target of 100 GW, the scale of operations will also increase by manifold. Thus, it is vital for investors to push the survival and transition of the noble yet commercial industry. Nowadays, investors are hiring Owner’s Engineer to keep a check on the quality of work done by the EPC companies. SOLAR POWER Despite these hurdles, this industry has grown dramatically in a short time span – courtesy intra-industry cooperation in expanding the PV supply chain. This unity and collaboration is needed now, more than ever before, to ensure that India does not gain notoriety for being a nation that consists of power plants built with low engineering standards. The union of knowledge, superior engineering, technique and high quality material along with liberal investment will ensure that land owners, entrepreneurs, financiers and of course consumers will benefit from the use of the incomparable natural resource, the sun! 33 energetica INDIA · SEP | OCT15
