Continuous Evolution of the Solar Energy Landscape: Recent Advancements

Energy CIO Insights | Monday, April 01, 2019

Solar technology made its debut in the 1960s, and since then, there have been various technological advancements in this field. The center of all technological advancements made in solar is the photovoltaic module. Monocrystalline has increased the efficiency range polycrystalline solar panel from 18 percent to 24 percent. 350Wp and higher is the power rating of the module with increased efficiency. PV inverter’s property decides the efficiency and reliability of solar power generation. In recent times, inverters are produced with inbuilt monitoring system with all possible communication protocols.

New generators play a significant role in cost optimization and machine intelligence of solar plants. During night times, PV inverters can now supply highly inducted loads like transformers. To meet inverter requirements, transformer designs have evolved in terms of dv/dt withstand, galvanic isolation, and impedances. To reduce the Balance of the system (BOS) Two Core Coil Assembly transformers are significantly used, and they are popular too. The advent of 1500V DC system has significantly helped the developers to operate and construct plants efficiently. The output of the PV power-plant can be boosted with a self-adjusting tracker system by 15-20 percent. These systems can monitor the weather conditions and continuously track and analyze the algorithm of each row. To maximize weather yield systems, enterprises could make use of machine learning, weather forecasting, and advanced sensors. Increase in power production will significantly improve the performance of the plant and reduce the operations cost.

Remote monitoring analyzes the health of the PV system. Solar plants are usually located in isolated places or industrial areas away from the residential place, and it becomes difficult for the provider to gain daily insights about the functions. Limited knowledge of the operation and maintenance manager about the weather conditions will gradually affect the plant. To overcome this obstacle, remote monitoring access is given to clients to create a sustainable ecosystem. Utmost care must be taken regarding data breaches, and cyber tools must be used to protect the data. To identify failures in the early stages, specialized SCADA systems are used. To provide seamless services, solar developers are marching toward energy storage to maintain energy flow during non-solar hours.
