PosiGen was founded in 2011 with one simple goal: give low and middle income families access to affordable solar and energy efficiency to dramatically cut their energy costs and improve their lives. In post-Katrina New Orleans, our founders shared the rebuilding city’s frustration that thousands of homeowners wanted to install solar and energy efficiency improvements in their homes, but were shut out due to the lack of significant income and high credit scores that other national solar companies require.
