Kumo Solar

Your AI solar copilot

Fast, Accurate, Global

Most PV tools are slow, manual, and built for a different era.

Kumo Solar changes that. Run trusted PV simulations, calculate losses, estimate PR and get real-time power forecasts — all through a simple chat.

Solar Power Simulations

in Minutes

Run full PV simulations by uploading your
PAN and OND files.

Upload your system file

Tell Kumo what years of weather data to use (e.g., 2005–2025)

Ask for any configuration changes in a chat

Get simulation results in minutes — not hours or days

No forms. No endless manual parameters. No re-building a project from scratch.
