15 mins read. A well-designed off-grid system will have solar panels that effectively charge the batteries while supplying electricity to its electrical load. Now, what happens to the excess solar power (off-grid) when the batteries are full? In this case, the solar power will be curtailed and be limited to what the load only requires.
In essence, solar export control refers to the amount of solar power you can send to the grid from a grid-connected solar installation. These limits can apply to any size of solar installation, from utility-scale projects to solar panels on private residences.
