Optimizers and microinverters respond to decreases in voltage and current in the solar array by adjusting the voltage to ensure the system is producing its maximum output. Microinverter converts at the module level. Hence shading on other modules does not affect each individual module’s energy output. Typical string inverters are limited by the current produced by the weakest module. That one module can then decrease the entire output of the string.
Also, these days, most modern MLPE products also include Web-based monitoring that allow system owners and technicians to remotely assess system performance and health at the module level.
Some PV module manufacturers have begun to investigate submodule-level power electronics in which the DC optimization circuitry is embedded in the module itself.
