90 solar sites connected through one asset performance platform

BCT deployed RETINA360 APM to standardise solar asset data, identify generation losses and guide maintenance across a distributed portfolio of rooftop and ground-mounted installations.

90 solar sites connected through one asset performance platform

Client

Challenge

Local data loggers sent site readings to a remote cloud, but the operator had limited visibility into the causes of underperformance. Generation shortfalls from string faults, shading and soiling were not quantified, making it difficult to distinguish equipment problems from other sources of lost output.

Without string-level downtime and loss analysis, teams could not prioritise panel cleaning and maintenance according to actual need. Differences in data formats and quality across logger vendors further complicated analysis. The customer needed a common performance model that could work across its existing infrastructure and support a repeatable rollout across a large, distributed fleet.

Solution

BCT deployed RETINA360 APM as a shared performance and loss analytics layer across data loggers, inverters and string-level systems. It connected to the existing logger infrastructure and standardised incoming data into a common asset and KPI model, addressing differences in format and quality before applying analytics.

The platform brought together Performance Ratio, insolation and generation monitoring with loss accounting. Teams could identify string-level downtime and losses, investigate shading and soiling, and use panel-cleaning recommendations based on site conditions to prioritise operational work.

Delivery began with a proof of concept at one ground-mounted site. After validating the approach, BCT sequenced onboarding by geography, combining rooftop and ground-mounted installations within each region. A repeatable integration process supported onboarding at approximately 10 sites a week.

BCT retains responsibility for platform configuration and operation, while the customer’s team uses the application day to day. This managed service approach supports consistent delivery as more sites are connected.

Impact

At the time of submission, 90 of approximately 150 sites were live on RETINA360 APM. The remaining international sites were still awaiting onboarding. The deployment established a unified performance view for the connected sites within a portfolio of roughly 600 MW.

Loss accounting gave the operator greater visibility into the causes of generation shortfalls. String-level analysis and shading and soiling detection helped teams investigate underperformance and prioritise cleaning and maintenance using asset data. Standardising information across logger vendors also supported more consistent analysis across the connected fleet.

The pilot and geographic rollout established a repeatable onboarding method, allowing the programme to expand at approximately 10 sites per week. The operator now has a common platform for performance monitoring and loss investigation as deployment continues across the portfolio.

Editorial note for review: The submission reports a 0.5–1% improvement in Performance Ratio and analysis in under five minutes, while the presentation labels these potential outcomes. Confirm measurement status before publishing these figures. They are not presented above as verified results.
