Designed, installed and fully managed

Commercial solar solutions are a key way that businesses can reduce their electricity costs and contribute to their net Zero targets. Solar is increasingly popular amongst even the largest global companies, many of whom opt for a fully funded solution as a way to both benefit from the energy and carbon savings but also to conserve capital for investment in their own businesses.

From rooftops to surrounding land and integrated carports, Zestec can assess all available options and size the systems appropriately to your business needs.
