There are three main types of inverters used in residential grid-tied solar systems: string inverters, microinverters, and power optimizers. Each has distinct operational characteristics.
String Inverters
A string inverter is a single, central unit that connects to multiple solar panels wired together in a “string.” This is often the most cost-effective option. However, if one panel in a string is shaded or underperforming, it can reduce the output of the entire string. For a roof in Teravista with consistent sunlight exposure, a string inverter can be a reliable choice.
Microinverters
Microinverters are installed on each individual solar panel. This means each panel operates independently, and shading or performance issues on one panel will not affect the others. Microinverters also allow for panel-level monitoring, providing detailed data on each panel’s output. While more expensive upfront, they are often favored for complex roof layouts or situations with potential shading.
DC Power Optimizers
DC power optimizers are another form of panel-level electronics. They are attached to each solar panel but work in conjunction with a central string inverter. Each optimizer conditions the DC power from its panel before sending it to the string inverter. This technology offers some of the benefits of microinverters, such as improved performance in shaded conditions and panel-level monitoring, often at a lower cost than full microinverter systems.
The Importance of Inverter Efficiency and Monitoring
The efficiency of your inverter directly affects the amount of electricity your solar system produces. Furthermore, its monitoring capabilities can provide valuable insights into your system’s performance.
