Global Solar Energy

Off-Grid Solar Panels

Founded in 1996, Global Solar© Energy Inc. (GSE) delivers lightweight and portable photovoltaic (PV) modules for integration in commercial, residential, off-grid and mobile applications. Currently, the company operates a Tucson, Arizona facility with a production capacity of 50 megawatts per year.

GSE is the first manufacturer in full-scale production of light weight and highly efficient PV cells and modules. By depositing CIGS on flexible stainless-steel substrate via a roll-to-roll process, the company decreases cost by streamlining production, increasing throughput, and improving material utilization. GSE’s unique products are opening up new and alternative markets where solar hasn’t been a viable option in the past, helping to drive the solar market into the next level of innovation, adoption and affordability.
