Solar Export Limiting: Just How Much Energy Will You Lose? Solar Export Limiting: Just How Much Energy Will You Lose? 8shares What are the losses from solar export limiting? — You’ll lose less energy generation than you think. Export limited solar systems are becoming increasingly common. Some new solar power system buyers are being told they can only proceed with an installation if the installer ‘export limits’ their system. Export limiting is a polite way of saying ‘hobbled’. An export limited solar system will occasionally send less electricity into the grid than its inverter can supply. That can cause clean solar energy to go to waste.
