Microinverters vs. String Inverters for San Antonio Solar Systems 

When it comes to solar systems, homeowners in San Antonio have a lot to consider – from the type of panels to the size of the system. One aspect that often is overlooked is the inverter. But what exactly is an inverter and why is it important? An inverter is a device that converts the direct current (DC) electricity produced by solar panels into the alternating current (AC) electricity that powers our homes and appliances. 

But not all inverters are created equal. There are two main types: microinverters and string inverters. 

Microinverters are small, individual inverters that are attached to each solar panel. This allows for greater flexibility in design and installation and the ability to monitor and adjust each panel individually. Additionally, if one panel is not performing as well as the others, it does not affect the entire system. 

Microinverters also have a longer lifespan, as they are not exposed to the same extreme temperatures and weather conditions as string inverters. 

On the other hand, string inverters are larger and centralized, with all the panels connected in a “string” and feeding into one inverter. This type of inverter is less expensive and simpler to install, but if one panel is not performing well, it can affect the entire system. 

String inverters also have a shorter lifespan due to the harsh outdoor conditions they are exposed to. 

So, what does this mean for homeowners in San Antonio? It’s important to understand the differences between microinverters and string inverters and the benefits of each. While microinverters may be more expensive upfront, they offer greater flexibility and a longer lifespan. However, string inverters may be a better option for those on a budget. 

It’s also crucial to have a solar installer who understands these technical issues and can apply that knowledge to ensure you a zero electric bill. Do not be afraid to ask questions and understand the options before deciding.
