Solar O&M CMMS built natively inside Microsoft 365. No subscriptions, full data sovereignty

Five Hundred is a solar operations and maintenance CMMS built natively on Microsoft 365 — Power Apps, Dataverse, Power Automate, and Power BI. It deploys inside the customer's own Microsoft Azure tenant. No WIZSP server ever touches your data.

Unlike SaaS CMMS platforms that charge monthly per-user fees, Five Hundred uses a CAPEX model: a single implementation fee, no recurring licence costs. As your portfolio grows from 50MW to 5GW, your software cost does not change.

Built for PV operators, Five Hundred covers the full O&M workflow: SCADA alarm ingestion with automatic work order creation, corrective and preventive maintenance scheduling, EHS and LOTO compliance, IEC 62446 documentation, and investor-grade Power BI reporting. Field technicians work offline via native Power Apps mobile.
