Gujarat Solar – SunEdison, Konark and Welspun top performing plants in 2013-14

We are glad to present the Second edition of the whitepaper “Sunrise in Gujarat”, a detailed analysis of the energy generation in 2013-14 of solar plants that were commissioned under the Gujarat Solar policy. In this edition, the number of plants analysed has increased to 65, from 50 in the first edition(download the first edition here).
Apart from the increase in the number of plants analysed, some new features have been added in this edition.
a. BKC WeatherSys, one of the leading suppliers of weather monitoring systems for solar PV plants, has shared some very interesting and useful insights on the impact of various weather parameters, especially humidity, on the performance of the solar PV plants. The analysisprovides some possible explanations as to why plants in some districts are performing better than others, based on the irradiation, ambient temperature and humidity data.
b. Two year comparison(2013-14 vs 2012-13) of energy generation for 48 plants have been carried out, and some possible reasons for variations looked at.
c. In the previous edition, information(modules, inverters, type of tilt, EPC,etc) for certain plants were not available. Some of the developers shared the information with us, and we have updated the same this edition. We hope that you will find the whitepaper useful. Please send us your comments/suggestions to and/or . The whitepaper can be downloaded by clicking on the image below.

  1. While it is interesting to note the effects of radiation and weather parameters on plant generation and CUF, it will be useful to look at how performance ratio (PR) of the plants compare on month to month basis. PR will indicate energy conversion or system level efficiency of the plant and will determine how well the plant is designed, installed and maintained. As both generation and CUF largely depend on amount of available radiation, they are location specific and do not exactly indicate how well the plant performs. We can undertake PR evaluation of these plants based on the available data. We had done this exercise back in 2012-13 for the Gujarat plants and the findings can be made available.

  2. Some of the other factors to consider are POA radiation as opposed to GHI and tilt angle of the plant. Once PR is evaluated, it can be further normalized to various weather parameters. The normalized PR can be used to compare PV and Inverter technologies, BoS, plant design and installation.
