Retrofit Battery Storage to Your Existing Solar System in Bognor Regis
Green Earth Sussex specialises in retrofitting battery storage systems to existing solar PV installations throughout Bognor Regis and the surrounding area. If you already have solar panels but no battery, adding storage allows you to use more of your own solar energy, reduce grid consumption, and gain backup power during outages.
Battery retrofits are compatible with most existing solar systems, regardless of age or manufacturer. We offer both AC-coupled and DC-coupled battery solutions, depending on your existing inverter and system configuration. Our expert team will assess your current setup, recommend the best battery option, and handle the complete installation with minimal disruption to your existing solar generation in Bognor Regis.
