With Solar power in the market for around 10 years, the older plants need to be checked for its generation and components warranty. Generation of power is of prime importance as the system ROI is irrespective without it. Various parameters like Module Mismatch, Uneven Panel Aging, module non-functioning, damage module, earth faults, higher resistance are some of the reasons for loss in generation. Our module level monitoring eliminates all the above constraint. With using retrofit technology, we can make sure that the plant operates to its potential.Our approach is to focus on maximizing plant useful life and generation maximization.
