On-site plant assessment focuses majorly on assessing a plant's current health quality and understanding the necessary steps which need to be taken to optimize the plant’s performance. 

• > Estimate the reasons for underperformance in your plant
• > Identify the causes of degradation and nature of defects in the modules
• > Evaluate the health of your BoS (both civil and electrical)
• > Suggest possible and most feasible solutions to improve generation from your     solar power plant

• > Drone and hand-held thermography of modules
•     and other BoS components
• > Module and string IV curve measurement
•     (for 1000V and 1500V system)
• > EL Image analysis
• > PR analysis
• > Visual inspection
• > Inverter measurements 
  •  - Inverter efficiency measurement
  •  - Inverter efficiency analysis (via data log)
  •  - Power quality analysis (Information of
  •     TDH & Harmonics)

To analyze and estimate the OPEX, CAPEX and revenue generation from the solar asset under bidding, technical performance of the plant is a crucial consideration. This study incorporates all the factors essential for understanding the technical aspects of the plant along with other maintenance and documentation evaluation.

• > Healthiness assessment of on-site testing of modules and other BoS     components via EL Imaging, Drone/Handheld thermography, mobile labs, visual     inspection, and earthing and structure coating testing
