Significance & Reliability of PV + storage

8th Oct 17  

The solar PV market in India has seen a meteoric rise. The year 2016-17 has seen a double capacity addition (see Figure 1) andit is expected that India would add close to 10 GW in 2017-18 an approximate of 130% year on year rise. However solar PV generation is highly intermittent in nature. Figure 2 shows the cumulative generation curve of solar PV plants in Gujarat. It is clearthat the solar energy can power the loads only during daytime. This limits the usage of solar PV plants at night reducing its reliability. Hence it is important to explore alternative solutions which would enable total reliability to solar PV.
