Success Story: Solar Energy Data Portal

Our experience delivering custom software development includes building a unified solar energy data platform that replaced fragmented vendor reporting.

The organisation required a reliable way to collect and standardise production data from multiple solar vendors. Disparate formats and inconsistent reporting limited operational visibility.

We designed a unified ingestion layer capable of processing both historical and hourly production data, normalising heterogeneous inputs, and supporting real-time analytics through scalable cloud infrastructure.

As a result, the company gained full ownership of its production data, improved monitoring accuracy, reduced operational friction, and established a scalable foundation for long-term optimisation.
