Research Interests:

1.    Estimation of PV Soiling loss

Assessment of PV soiling loss in arid and semiarid region is required to forecast the PV generation loss under dusty environment since it will increase the system operational efficiency of a solar PV integrated power system. Inclusion of the harsh weather conditions like snow fall, sand storm, cementation is needed in the model for monofacial module. Analyse the effect of dust in industrial belt. Some more physical processes like dust deposition due to precipitation at the back surface of bifacial module has to be included to get more accurate results appearing at different places. Use the develop model to optimize and scheduling the power system operation of a PV integrated power system.

2.    Validation of PV Soiling model for providing better generation guarantee in different PV applications

Model for monofacial module is to be validated for more national and international plants installed in dusty environment and desert areas. Bifacial PV soiling model is to be validated in various applications (e.g., agrivoltaic, plant in desert area etc.). Develop a user-friendly software package including both types of models (monofacial and bifacial) for PV plant design engineers to assess the soiling related generation reduction of a PV plant for a particular location instead of using an ad hoc value for the soiling losses.

3.    Development of dust detection, cleaning technology

Develop a simple and automatic dust detection mechanism to optimize the cleaning frequency and usage of water in water-based cleaning system. Analyse the effect of different anti soiling coating in field application. Analyse the effect of different cleaning technology in field application.

4.    Analyse the effect of different backsheet (BS) materials in PV performance

Characterization and evaluation of industrial grade different BS materials to selecting the correct material in particular applications. Estimate the life time of the BS in certain PV installation. Estimate the effect of BS material health to PV module life and performance.

5.    Image assisted degradation analysis of PV module

Use image analysis method to assess soiling loss in outdoor condition. Use this to detect the module health and module performance and reliability in field.

6.    Assessment of performance of renewable system integrated to existing grid 

Study the energy management with uncertain renewable source and variable load to maintain the system stability and optimize the cost of operation. Use bioenergy, hydrogen energy, battery energy sources and EV (as load and source when needed) in renewable integrated power system, to maintain operational stability, as these sources are of utmost importance. Include PV module reliability in assessment of power system reliability.
