How it works

01

Check your roof

Live data from the City of Vienna solar map shows what your roof could produce.

02

Invite your neighbours

Share one link. Neighbours answer yes, maybe or no, without an account.

03

Send the pack to your property manager

A summary, a checklist and a formal email, ready to send.
