The problem
To cut a power bill with solar, a consumer normally has to buy and install equipment.
What we built
We built SunDeal in Palmas, Brazil, on the distributed generation model: customers sign up, subscribe to solar power and get a discount on their bill, with no panels to install.
How it works
Sign up
The customer signs up.
Subscribe
They subscribe to solar power.
A lower bill
A discount on the power bill, no panels to install.
Outcome
We took SunDeal to an exit: the company was sold in 2025 and still operates in Palmas, Brazil.
Today
Today SunDeal describes itself as the largest producer and manager of low-voltage solar energy credits in the state of Tocantins, with its own and partner plants.
