Solar inverters are one of the most important components of a solar panel system. They’re responsible for converting direct current (DC) electricity from your solar panels to alternating current (AC) electricity to power your appliances. When it comes to designing your solar panel system, the size of your inverter will play an important role in overall electricity production. In this article, we’ll discuss what impacts solar inverter sizing.
If you want to maximize your solar energy system’s production, finding the best solar inverter is as important as the solar panels you choose. For an “uncomplicated” roof – one that faces south and has no gables, chimneys, or other obstructions that can cast a shadow – the best solar inverter for you may be a standard string inverter. However, more than half of new residential solar installations are using module-level power electronics (MLPEs) like power optimizers and microinverters to maximize electricity production.
If you want to make sure your solar panel system is operating as efficiently as possible, you are probably considering either power optimizers or microinverters (collectively known as “module level power electronics,” or MLPEs). In the United States, SolarEdge is the leading power optimizer manufacturer, and Enphase leads the pack for microinverters.
If you’ve been shopping around for a solar panel system, you may have heard of microinverters (from companies like Enphase and SolarBridge) and power optimizers (from companies like Tigo and SolarEdge). These devices – collectively referred to here as Module-level Power Electronics (MLPE) – are quickly gaining popularity in the US as an alternative to conventional string inverters.
In this article we take a look at this emerging trend and examine whether these technologies are the best option for all homes.
