Manage String & Panel Mismatch

Running a solar array is a bit like running a small-scale power grid. Each solar panel acts like a power plant, contributing its share to overall capacity.

Utility companies know that electrical grids work best and place the least stress on their components when they run at a constant voltage. Solar panels, however, put out variable voltages, depending on panel type and age, environmental factors like shading, dirt, and temperature, and interaction between panels. In practice, the poorest-performing panels drag down the best, slashing array output and efficiency.

By stepping up and stabilizing the output voltage of every panel, eIQ Energy's vBoost module creates a constant-voltage bus – so the array's inverter always operates at its most efficient point with minimum stress. The Parallel Solar architecture and vBoost's advanced power semiconductor technology let every array operate like a grid.
