Charts: User-defined, customizable, intuitive

  • Create your own diagrams on the fly
  • Fast data access to different time scales, different data resolution; easy axis scaling, color coding of parameters.
  • Sub-graphs put your data into full context - easy to identify outliers, trends or quality issues. 
  • Plot all environmental parameters on the fly
  • Apply pre-defined filters
  • Tooltips and automatic scaling
  • Table view and direct export

Teamwork function

  • One unique URL of analysis - anytime, anywhere
  • The new "Teamwork function" allows your analysis to be directly bookmarked, shared and and discussed with your O&M team.
  • Simply by sharing the URL your team will see exactly the same graph with all selected channels, configuration, filters etc.
  • Data analysis and documentation - the easy way

Investor dashboard

Data processing

Data processing in real time

  • For optimized PV Plant performance a platform is required to harmonise the incoming data from all components in the PV plant. 
  • With advanced platforms and incorporated algorithms in the gantner. webportal, the ultimate target of preventive maintenance for lowest Levelized Cost of Electricity (LCoE) is possible.
  • Perform real-time sanity checks for physical meaningful values (sensors, strings, inverters, grid)
  • Easier with normalised data, redundancy e.g. with NOCT, weather (kT, BF, ..), DC, AC, solar position, AOI, ..
  • Make uptime tracking / availability audits
  • Monitor irradiation sensor drift

Data processing - solid and traceable data consistency

  • When it comes to data analysis, data consistency is the key. 
  • That´s why we execute the following:
    • Incoming data is tested for measurement consistency, data consistency or data transfer issues
    • Missing data points are tagged
    • Includes also global filters and error limits to identify any issue later on.
    • Provide overall sensor reviews for measurement validity

Analysis

Analysis Features

  • Functions are designed to increase the work efficiency for the owner and O&M team. Information is pre-aggregated to deliver key performance indicators.
  • Current, voltage (DC and AC side), Pdc, Pac, Eac, Edc, PRdc, PRac, efficiency, YR, YA, YF - per component. 
  • Normalization of all parameters for direct comparison and faster analysis
  • Temperature and irradiance correction on the fly
  • Automatic calculation of sun height, angle of incidence (AOI), clearness index (kTx)...
  • Capacity testing configuration
  • New Filter Parameters: 
    • Sun position, AOI, shading status, clearness index (kTh), module temperature (irradiation weighted)

Component comparison - Table view

  • Identification of under-performing  inverters, strings, .. in real time
  • Available for all components, electrical parameters (absolute & normalized)
  • Select your own limits and start - stop dates
  • Compare based on mean and median values, standard deviations, etc.
  • Provide baseline for O&M activities and to keep performance guarantees
  • Directly linked to heatmap plots

Identify and validate your concerns via heatmaps

  • Real time data processing
  • Allows absolute, relative and staticital analysis
  • Analyze absolute, normalized or digitized results.
  • Configure your own limits, ranges and filters
  • See when your inverter is switch on, has wake-up problems over time, etc.
  • Directly linked to table view

Issue Management

Issue management

  • Report and track issues on from anywhere
  • Delegate tasks and trigger repeatable activities for your sub-contractors
  • Keep track of all your activities via portfolio analysis 
  • Upload your picture instantly if you are on site.
  • Issues and sub-issues can be linked with inventory, structure and user rights. 
  • Automatic communication via e-mail or on website. 
  • Easy to export and integrate into asset management solutions
  • The issue management system can be combined with O&M logging and document handling to improve tractability, sensor calibration, and cleaning.

Inventory

Inventory of your asset

  • The inventory includes PV modules, strings, string monitoring, string combiners, inverters, sub-station, etc.
  • Fully integrated for central and decentral concepts
  • Easy Inventory handling: sort by firmware, installation date and many more
  • Grouped by products, articles, ...
  • Includes product pictures, data sheets, firmware updates, counter status
  • Sensors include calibration value and re-calibration date
  • Connectable with your own ERP tool
  • Fully linked to the issue management system

Structure

Structure

  • Get the big picture and quick localization of problems in one smart function
  • Plant structure (generated during data import) allows design & sanity checks
  • Fast validation check of all measurements (sensors, inverters, strings)
  • Compare performance of peers , localize issues.
  • Data aggregation of selected component including existing issues, alarms, warnings (pop-up)
  • New issues can be created directly
  • Full site structure is generated automatically from the Q.reader central data stream

Availabilty Reporting

Availability reporting for all components

  • Run your customized availability calculation to meet your PPA /IPP contract requirements.
  • Calculation for each component  (string combiner box , inverter, sub-station, grid) including interpolation. 
  • Make your calculation for production batches, years or firmware versions.
