Inverter Options & Panel Level Optimization

Panel level optimization allows for each solar panel to be optimized individually, enabling every panel to perform at maximum potential. These systems see improved energy harvest and increased reliability, and meet the National Electric Code 2017 module level rapid shutdown requirements. DC optimized systems and microinverter systems both offer these benefits and are compliant with the NEC requirements.

DC OPTIMIZERS - Buck Converters

When shading or cloudy situations occur, the panel with the lowest voltage will be “bucked” off the string so as not to reduce the voltage and impact the performance of the remaining modules. Buck optimization, such as Tigo, is less expensive but has limited applications on roofs with multiple orientations or heavier shading.

DC OPTIMIZERS - Buck-Boost Converters

During shady conditions, lowest performing modules are bucked off the string, but the voltage of the remaining modules is boosted to allow the inverter to continue operating optimally. Buck-boost optimization, such as SolarEdge, is more expensive but has a greater range of applications and typically will increase a system’s production beyond that of a simple buck converter system.

DC OPTIMIZERS - Buck-Boost Converters

Each panel is connected to its own dedicated inverter, allowing it to operate completely independently from the rest of the array, so lower production from one panel has no impact on the production of the others. Microinverters, such as Enphase, are a good fit for smaller systems and sites with heavier intermittent shade or multiple roof faces, and also make it simple to expand your system in the future.
