The Gantner.webportal is an independent real-time analysis platform for data acquisition, storage and control of your PV portfolio which offers investors solid and reliable information (Financial KPIs, Performance Analysis) enabling them to evaluate their PV portfolio performance and develop preventive maintenance strategies.
Also, performance guarantees – target versus actual performance – can be reflected and the responsible losses can be identified. This identifies further optimization potential (in terms of kWh or $) and is leading to effective O&M and risk reduction for all involved stakeholders.

- Apply pre-defined filters
- Tooltips and automatic scaling
- Table view and direct export
- One unique URL of analysis - anytime, anywhere
- The new "Teamwork function" allows your analysis to be directly bookmarked, shared and discussed with your O&M team
- Simply by sharing the URL your team will see the same graph with all selected channels, configuration, filters etc.
- Data analysis and documentation - the easy way
Data processing in real time
- For optimized PV Plant performance, a platform is required to harmonize the incoming data from all components in the PV plant
- Reaching the target of predictive maintenance for lowest Levelized Cost of Electricity (LCoE) is possible with advanced platforms and incorporated algorithms in the Gantner.webportal.
- Perform real-time sanity checks for physical meaningful values (sensors, strings, inverters, grid)
- Easier with normalized 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
- focusing on 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
- use of global filters and error limits to identify any future issue
- overall sensor reviews for measurement validity
- 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
