Unleashing the power of your solar panels requires more than just sunlight. Inverters are essential components of every solar panel system. Think of it like this: Solar panels capture energy from sunlight. Inverters harness that energy to create electricity compatible with your home.
More specifically, inverters convert the direct current (DC) electricity your solar panels generate into alternating current (AC) electricity that your home appliances can use. These unsung heroes of solar panel systems come in all shapes and sizes and contribute to the overall efficiency of your system.
While traditional string inverters connect multiple panels to a single inverter, microinverters operate at the individual panel level. They can optimize the conversion process to boost your solar panel system''s efficiency. Let''s dive deeper into microinverters, their technology, and how they compare to other inverters.
Microinverters convert the electricity from your solar panels into usable electricity. Unlike centralized string inverters, which are typically responsible for an entire solar panel system, microinverters are installed at the individual solar panel site. Most solar panel systems with microinverters include one microinverter on every panel, but it''s not uncommon for one microinverter to connect to a handful of panels.
Microinverters are classified as module-level power electronics (MLPE). Each microinverter operates at the panel site independently of the other inverters in the system. The individual nature of microinverters is advantageous for complicated installations or those with shading. Due to its centralization, traditional string inverter technology operates at the level of the lowest-performing panel. With microinverters, solar panels have their own inverters and will continue performing efficiently even if one panel isn''t producing as much electricity as the others.
Microinverters are an excellent investment for most solar shoppers, especially if you have a complex roof or one with partial shading. Microinverters operate at the panel level and don''t require power optimizers for rapid shutdown compliance and optimization. If something is wrong with one microinverter, only the panel attached to it will shut down instead of the entire system. Diagnosing and fixing issues with microinverters is often quicker than with central string inverters.
Microinverters can easily grow with your solar panel system over the years. Let''s say your energy demands increase in the future. You can add more panels with microinverters instead of matching the power output of a central inverter with your new system size. Plus, most microinverters are warranted the same amount of time as the panels they''re attached to (typically 25 years), so you can expect them to last longer.
Microinverters are generally more expensive than string inverters. While you''ll likely have better overall system performance with microinverters, it''s important to ensure that the long-term performance benefit outweighs the upfront cost. Microinverters are also located on your roof, making maintenance more difficult (and costly if your warranty doesn''t cover labor). Alternatively, string inverters typically sit more conveniently on the side of your house.
Clipping refers to power losses associated with microinverters and is an important consideration when shopping for a solar panel system. Often, the power output rating of your microinverter is lower than that of the panel itself. If your solar panel produces more electricity than its microinverter can convert at a given moment, clipping occurs, and your system can''t take advantage of the full power output of your solar panel.
Many homeowners choose microinverters. They''re by far the most popular option on EnergySage. In part, this is due to their improved performance. Some installers also prefer them, meaning they include them in quotes more frequently.
Microinverters are a great choice if your roof has multiple planes facing different directions. They also make sense if your roof experiences shading throughout the day or has different angles to it. Let''s say you have some panels facing east and others facing south. In this case, microinverters optimize performance by isolating each panel''s production issues.
However, if you have a single roof plane that''s south-facing without shade, we recommend talking to our installer about different options. In this case, microinverters probably aren''t worth the extra cost.
Wiring is the biggest difference between string and microinverters. Depending on the size of your solar panel system, you only need to use one or two string inverters to wire your panels. Microinverters often connect to just one panel.
Given the minimal wiring requirements, string inverters are cheaper to install and maintain than microinverters. That said, the simplified wiring scheme can also make it more expensive to expand your solar system in the future. It also means that underperforming solar panels will affect the whole circuit rather than just its own output.
Unlike micro and string inverters, power optimizers don''t immediately convert direct currents to alternate currents. Instead, they "condition" it and send it to a centralized inverter. These module-level power electronics (MLPEs) are similar to microinverters because they can monitor individual solar panel performance and allow flexibility when building a solar system.
Just like solar panels, microinverters have varying efficiencies. An inverter''s efficiency measures energy losses during the conversion from DC to AC electricity. The more efficient the microinverter, the more solar electricity production.
