Soluz, Inc. provides advisory services to international institutions assisting efforts that advance the global transition to sustainable energy, especially to increase access to energy.  Clients include the public sector, including multilateral development banks (the World Bank and the Inter-American Development Bank), as well as NGOs and private sector companies engaging in the global transition to sustainable energy.

Over two decades, Soluz has had many assignments to advance the use of solar PV for rural electrification in developing countries around the globe.  Soluz has provided a range of consulting services including program feasibility/design and rural energy enterprise development.  Some examples are listed below. 

In recent years attention to climate change and the UN Sustainable Energy for All initiative have led to greater efforts to scale up renewable energy and to address energy access. Soluz has been engaged to assist with various dimensions of this effort, as listed below.
