Our Business Model


Gigasun’s business model is to finance, install, own and continuously manage solar PV installations on the roofs of our clients; mainly medium-sized and large private public companies, state-owned companies and organisations such as universities. The client does not pay for the solar PV installation but commits on 20-year contracts to buying all the electricity that their respective installation generates.

Ongoing revenue comes from the sales of electricity to our clients. Our strategy is to build an order book aiming at an installed capacity of 1,000 MW that is fully connected to the power grid by the end of 2026. The exact annual rate of installation depends on the availability of capital.

Solid contracts with the clients provide long-term and stable cash flows while ensuring the company’s ownership of the solar PV installations.

Our clients in China, our investors and Gigasun itself all benefit from this business model, as does the environment.
