Solar operations platform

Operational infrastructure
for solar asset management.

Every solar project runs on documents. PPAs, leases, interconnection agreements, O&M contracts — the rules, the rates, the deadlines. Upload them once and Sunny can answer against your operating record instantly. No more digging through folders.

From there, SunStack handles the rest of your monthly workflow — generating invoices, tracking tasks and deadlines pulled straight from your contracts, and giving you a live dashboard across your entire portfolio.
