As the renewable energy sector scales rapidly, effective portfolio management has become as critical as generation capacity. With solar and battery storage projected to account for 81% of new US electric-generating capacity in 2024, companies such as Sol Systems are refining how they manage increasingly complex asset portfolios.
Sol Systems oversees a 7GW portfolio of clean energy projects across North America, spanning both operational and in-development assets. To manage this scale, the company has prioritised integrated asset management and centralised data oversight, enabling real-time visibility into both financial and operational performance. This approach supports faster response to operational issues, improved asset optimisation, and tailored reporting for a diverse client base that includes commercial customers and landowners.
Managing such a portfolio generates significant volumes of data across development, financing, procurement and operations. Sol Systems uses the Radian Digital platform to centralise and manage information across its US$2bn portfolio, ensuring transparency, accessibility and accountability across stakeholders.
“As you start building a renewable portfolio, you add more projects, have unique investors, and everyone has their custom requirements. Centralising all information into a single source of truth is critical to maintaining data integrity and quality,” said Adam Polis, performance engineering manager at Sol Systems.
The need for centralisation extends beyond performance monitoring. Long-term agreements, such as power purchase agreements spanning decades, introduce complex lifecycle requirements, including scheduled decommissioning and evolving stakeholder responsibilities. Workforce mobility further compounds this challenge, reinforcing the importance of a unified system to track obligations, set alerts and manage tasks across teams.
Data complexity is also heightened by the diversity of equipment across sites. Solar panels and monitoring systems from different vendors often produce inconsistent data formats. Through Application Programming Interfaces (API) integrations, Sol Systems aggregates and standardises this data within a single platform, enabling consistent monitoring and faster fault detection.
The financial implications of outages, whether large-scale or incremental, are a key focus. In 2023, the US recorded 28 weather and climate events exceeding $1bn in losses. While such events are significant, smaller, distributed outages across a portfolio can cumulatively have substantial financial impact.
“Our goal is to measure the impact of each outage and quickly quantify its business impact so we know where to deploy resources,” said Polis.
Using detailed asset mapping and minute-level data analysis, the platform quantifies losses down to individual components. This allows Sol Systems to translate performance issues directly into financial terms, prioritising maintenance based on economic impact rather than operational convenience. Repair workflows are supported by detailed ticketing, ensuring maintenance teams are equipped with the necessary information and resources before arriving on site.
“We do not want our O&M providers inadvertently prioritising lower-impact components. It is not the list that matters; it is the dollars lost based on each individual outage,” Polis added.
Beyond operations, centralised data enhances reporting and compliance. The platform enables rapid generation of both routine and ad hoc reports, supporting investor-specific requirements and near real-time analysis. Queries that would otherwise be resource-intensive can be addressed quickly through pre-integrated datasets and automated calculations.
As Sol Systems continues to expand its operating assets and development pipeline, the ability to unify data across teams and stakeholders remains fundamental. Centralised platforms not only reduce data silos but also enable more informed decision-making, supporting both operational efficiency and long-term portfolio performance.
