This laboratory showcases SERIS’ real-time analytical monitoring capabilities of photovoltaic systems as well as meteorological parameters. Our proprietary award-winning monitoring system is based on rugged industrial-grade hardware from National Instruments and LabVIEW software for remote data logging and remote control of SERIS-monitored PV systems and meteorological stations. The monitoring system is highly versatile and can be customised to meet any specific project requirements. It has been deployed successfully in numerous PV projects across Asia-Pacific and Europe, and it also fulfils the stringent data requirements of EMA PSO, Singapore’s power system operator, for PV systems in Singapore.
Features of SERIS’ live monitoring systems include:
- Real-time (“live”) data transmission for key PV system and meteorological parameters
- Submission of live power and irradiance data compliant with requirements from power system operators (PSO), e.g. Singapore’s Energy Market Authority (EMA)
- 1-second resolution of various DC and AC parameters of PV systems, power quality parameters, and meteorological parameters, such as irradiances measured with different sensor devices and inclinations, module and ambient temperatures, relative humidity, wind speed, wind direction, air pressure, etc.
- ± 150 ms time synchronisation with cloud-based time servers
- Greater than 99% data acquisition availability
- Secure data communication via VPN over 4G network
- Live irradiance map for Singapore (spatially resolved). The map can be accessed online at the National Solar Repository (NSR) website, www.solar-repository.sg
- Solar irradiance forecasting algorithms with different forecast horizons (from 5 minutes to 24 hours ahead)
- Tailored alarm system according to customer needs (such as inverter trips, grid outages, system underperformance), including SMS and email services
- High-quality online or screen visualisation for various target groups: Operations managers, engineers, general public (for example through displays in corporate entrance areas). Daily summary reports of PV system status and performance data via email.
