There are quite a lot of things that need to be planned and considered as the project of installing solar panels on your property is beginning. Having it all planned beforehand is always the best option but quite a lot of people think that starting it and deciding all of the things at the particular moment is better because of their lack of knowledge of what exactly they need to purchase, how to install it, who to ask for tips and suggestions, how much money would be actually needed in the end and so on.
Apart from choosing the type of solar panels, their amount as well as their prices, which determine the final solar panel cost of the project, there is also the need to understand the differences between the different inverters for solar panel systems in order to buy the best one for your property.
The solar panel cost is also affected by the type of inverter you will be needing not only because of their difference in prices, but also if you are planning to hire a service for installing the solar panel system on your property. Keep that in mind as you are making your choice and considering the final solar panel cost of your solar power project. There are three main inverters – the micro inverter, the string inverter and the central inverter.
The micro inverter has several features. It is suitable if you have different modules that you want to include in the same system which is especially helpful if you need to repair or replace any of them after a while. There is also no need of any string lengths calculations and there is an increase in the flexibility of the design, which is quite important for a lot of people and their properties. Micro inverters also allow monitoring of the panel levels, as well as require lower voltage of the DC.
This type of inverter can also provide the possibility for panels to continue working even if there is one panel among them that has failed and it is no longer working. Therefore, with this inverter it is possible for the system to continue working even when there is a module not working properly, which is convenient if you are not at the property all the time and cannot check it if it is all working fine.
String inverters allow for remote monitoring of the system, have very low costs, as well as high efficiency and also allow high flexibility of the design. They also have the option of three different phase variations. The string inverter can also robust. The central inverters are usually a great option for commercials, governments, industrials, as well as field applications that are large-scaled. They can be considered as string inverters but with very large sizes. Choosing the right inverter is very important for the efficiency of the whole power system so be patient and consider your options carefully.
