As they relate to fixed solar solutions, what is the difference between “grid attached” and “off grid?
“Grid attached” means the solar cell solution is installed where attachment to the electric utility is also present. “Off grid” means installation is remote from any utility connection. Due to today’s high-amortized cost for solar energy solutions vs. getting power from electric companies (the electric grid), most solar solutions in the United States have been installed in remote locations without electric company access (off grid). This has impacted growth in the US, and therefore, about 75% of solar solutions are being installed outside of the US where electric costs are either higher or electric connections are not available. To be truly successful, solar solutions must be competitive in energy grid attached solutions. This means comparable cost to the power companies $/kW.
