In the following, we clarify What is a microinverter?, What is the role of a micro inverter?, What is the difference between an inverter and a micro inverter?
What is a microinverter?
A microinverter is a small device used in photovoltaic systems that converts direct current (DC) generated by individual solar panels into alternating current (AC). Unlike traditional string inverters that manage power to multiple panels, microinverters are installed on each panel, allowing them to operate independently. This configuration can improve the efficiency of the solar system, because the performance of each panel is optimized individually and shading or dirt on one panel does not affect the others.
What is the role of a micro inverter?
Microinverters are primarily used in photovoltaic systems where efficiency optimization is crucial and panel-level optimization is desired. They are particularly useful in installations where panels are exposed to varying levels of sunlight due to shadows from trees, buildings or other obstructions. Microinverters are also useful for systems with panels installed at different angles or orientations, because they ensure that each panel performs optimally regardless of the conditions affecting the others.
The choice between a traditional inverter and microinverters depends on specific needs and preferences. Microinverters offer benefits such as improved power production through panel-level optimization, increased system reliability because the failure of one microinverter does not affect the entire system, as well as easier monitoring and troubleshooting. However, they are generally more expensive than string inverters. String inverters are less expensive and simpler, but may not perform as well in situations with partial shading or varying panel orientations. The decision should be based on factors such as system design, budget and performance requirements.
What is the difference between an inverter and a micro inverter?
The cost of a microinverter varies depending on the brand, model, and features. On average, microinverters can cost between $100 and $200 per unit. The total cost will also include installation and potentially higher system costs due to the need for multiple microinverters versus a single string inverter. It is essential to consider the overall benefits and potential increases in energy production when assessing the cost.
Typically, each microinverter is designed to handle the power of a solar panel. This means that for each panel in your system, you will need a microinverter. In some cases, there are microinverters capable of handling two panels, but this configuration is less common. The exact number of panels per microinverter will depend on the specific model and its rated capacity. It is therefore crucial to match the specifications of the microinverter to the power output of the solar panels used.
