Here is a comparison between the two:

1. Inverter:

   • An inverter is a central unit that converts the direct current (DC) produced by the solar panels into alternating current (AC) suitable for use in the power grid.

   • It is typically installed as a single unit connected to multiple solar panels.

   • Inverters generally have higher power and can handle multiple solar panels simultaneously.

   • They are less expensive than micro-inverters, which can result in lower installation costs.

   • If there is an issue with one of the solar panels, it can affect the performance of the whole system, as all panels are connected to the same inverter.
     
     

2. Micro-inverter:

   • A micro-inverter is a small device that is installed directly under each solar panel and converts the direct current (DC) from that specific panel into alternating current (AC).

   • Each solar panel has its own micro-inverter, which means that each panel operates independently of the others.

   • Micro-inverters can optimize the yield of each panel since any shadow, dirt, or problem with one panel does not affect the performance of the other panels.

   • They offer panel-level monitoring, allowing you to track the performance of each individual panel.

   • Micro-inverters are generally more expensive than a central inverter, which can lead to higher installation costs.

Overall, the choice between an inverter and a micro-inverter depends on factors like the size of your solar energy system, the configuration of your roof, the degree of shading, the available budget, and your personal preferences. It is advisable to seek advice from a professional solar system installer to determine the most suitable option for your specific situation.
