SCADA Restoration of Solar Plants

In our interactions with Solar plant owners/operators, we came across this customer who was agitated. Large parts of his solar plant had suddenly become invisible to him in his SCADA dashboard ! Even more distressing was the fact that several months had passed with no solution in sight.   Utility scale Solar plants use expensive SCADA solutions to keep track of Generation and the working of all key assets in the plant.  The assets monitored typically consist of Inverters, Energy meters,....

Distributed Rooftop Solar Monitoring using Megamic's wiseNET Technology

Recently; a customer approached us for a Remote Monitoring Solution for their distributed Rooftop Solar installation in a large educational campus. The challenges posed were the installtion was spread across 13 building in the campus( with 16 inverters) and no interconnecting wires were allowed!  ....

SolarNxt - Remote Monitoring SCADA with Performance Analysis

Most of the Indian Solar PV Plants have not crossed 10 years since their installation. As plants age, there is a gradual degradation of performance as expected by design of upto 1%. Any degradation in yield more than 1% indicates that one or more components in the plant such as Inverters / Solar Modules or even DC Bus cables are beginning to show signs of under performance.  An efficient way to diagnose or pin point source of under performance is by data analysis. For data analysis, we need....

Mythbuster: Remote Monitoring of Solar Plants is not worth its Expense !

From a Solar PV Plant owner perspective, the benefits and value addition of installing Remote Monitoring Systems in Solar PV Plants far outweigh its recurring costs.   A simple calculation explaining the RoI associated with annual costs of Monitoring follows: Example Plant Capacity: 1 MW Monitoring Costs Per MW: Rs. 15,000 /- Tariff assumed: Rs. 3 /- Annual Plant Generation for 1MW in Units (approx.): 13.1 Lakh Units Annual Plant Generation for 1MW in Rupee Terms (approx.): Rs. 39.3 Lakh Yield....

String Monitoring Evolution !

  Did you know that a typical 1MWp Solar Power Plant can have upto 180 Strings spread across an area of 5 acres or more ?   To make the definition of a String clear, it is the series combination of 22 to 24 Solar PV panels. This ofcourse is assuming that the standard PV panel used is 230W rated with 30V approx. of MPP voltage. With a head count of about 4-5 onsite technicians, it is humanly a challenge for the onsite team to inspect and visually check each String cables/connections on a daily....
