What is an inverter?
In the context of solar panel installation, an inverter is a crucial component of a solar energy system. Solar panels generate Direct Current (DC) electricity, which is not suitable for home appliances as they require Alternating Current (AC) electricity to run. Therefore, an inverter is used to convert the DC electricity generated by the solar panels into AC electricity that can be used by the appliances in the house.
An inverter works by taking the DC electricity and then passing it through a transformer, which converts the voltage level to the necessary voltage required by the AC devices. Inverters also change the DC electricity’s frequency to match the AC devices’ frequency, allowing the use of the same power supply.
There are various types of inverters used in solar panel installation. The most common type is the string inverter, which is typically installed in a central location and connected to a series or “string” of solar panels. Another type of inverter is the micro inverter, which is placed on each solar panel and converts the DC electricity generated by each panel into AC electricity. This results in higher efficiency, as shading or malfunctions of one panel does not affect the output of the others.
Overall, the inverter plays a crucial role in converting the DC electricity generated by solar panels into AC electricity. Therefore, selecting the right type and quality of inverter is essential for maximizing the efficiency and output of a solar energy system.
Why are inverters necessary?
Inverters play a crucial role in the installation of solar panels.

String inverter vs microinverter
When it comes to solar panel installations, inverters are a crucial component responsible for converting DC power generated by solar panels to AC power that can be used to power your home or business. One common question that arises during the installation process is whether to use a string inverter or a microinverter.
String inverters are larger, centralized inverters that are typically mounted on a wall or placed on the ground near the solar panels. They are designed to handle the power output of multiple solar panels that are wired together in a series (string). String inverters work well for larger installations and can be less expensive compared to microinverters.
On the other hand, microinverters are smaller, individual inverters that are attached to each solar panel in the array. Microinverters work independently, meaning that each panel operates individually and optimizes the amount of power it produces. This is in contrast to the string inverter that takes the output of all the panels in a single string.
Microinverters have a number of advantages over string inverters. They are efficient, provide better performance in partially shaded conditions, and offer more flexibility in system design. In addition, microinverters are easier to install, monitor and maintain, as they are mounted on the solar panel, eliminating the need for additional wiring and grounding.
However, despite all these benefits, microinverters can be more expensive compared to string inverters, especially for larger installations. You should also consider that microinverters increase the number of components in your system, which could potentially lead to more points of failure, although manufacturers offer warranties to address these concerns.
Ultimately, the decision to use a string inverter or microinverter will depend on the specifics of your installation requirements and budget. Your solar panel installer can help you determine which option is best suited for your needs.
Central inverter vs string inverter vs microinverter
When it comes to solar panel installations, the type of inverter used is a crucial factor in determining the efficiency and overall performance of the system. There are three main types of inverters used in solar panel installations: central inverters, string inverters, and microinverters.
Central inverters are typically used in larger solar panel installations, and are responsible for converting the direct current (DC) generated by the solar panels into alternating current (AC) that can be used to power homes and businesses. These inverters are installed at a central location and are connected to multiple strings of solar panels. One of the benefits of using a central inverter is that they are typically less expensive than other types of inverters. However, central inverters only work as well as the weakest panel in the system, which means that if one panel is covered or shaded, the efficiency of the entire system can be impacted.
String inverters are similar to central inverters, but instead of connecting to multiple strings of solar panels, they are connected to each individual string of panels. This means that if one panel is shaded or covered, it only affects the efficiency of that particular string, rather than the entire system. String inverters are less expensive than microinverters, but more expensive than central inverters.
Microinverters are the most expensive type of inverter, but they also offer the highest level of efficiency and performance. Unlike central and string inverters, which are both connected to multiple solar panels, microinverters are connected to each individual panel. This means that each panel operates independently, which allows for higher energy production and increased efficiency. Additionally, microinverters are not impacted by shading or covering of a single panel, which means that the overall system efficiency remains high. The downside of microinverters is that they are more expensive than other types of inverters, and may not be necessary for smaller or less complex solar panel installations.
In summary, the choice between central, string, and microinverters depends on the size and complexity of the solar panel installation, as well as the desired level of efficiency and performance. While central inverters are less expensive, they may not be the best option for larger installations or those that are likely to experience shading or covering of individual panels. String inverters are a good middle ground option, offering higher efficiency and performance than central inverters, but at a lower cost than microinverters. Microinverters are the most expensive option, but offer the highest level of efficiency and performance, making them a good choice for more complex installations or those that require the highest level of energy production.
When it comes to solar panel installation, an inverter is an essential component of the system. Its function is to convert the DC power generated by the solar panels into AC power that can be used in your home.
