Solar PV is a pretty intelligent thing! Not only is it able to harness the sun’s abundant and free energy source, but it converts this into electricity that can be used to power the home or business – just like grid energy would. Of course, with such innovation comes an abundance of technology, gadgets and gizmos that help the smooth transition from sun to socket and inverters are a vital component.
A solar PV inverter will convert the DC energy that is generated, into AC so that end-users can enjoy the benefits of sustainable electricity throughout their daily life. However, there are two forms of inverter available to do this and these are:
String Inverters
They convert the DC electricity that has been harvested into AC and there are usually up to two for domestic applications and several for commercial installations.
Microinverters
Ultimately taking on the same job as a string inverter, by converting DC to AC,microinverters work by attaching to each individual PV module where the power is fed to a central electricity supply that powers homes or business.
Power Production
As each microinverter is working for a single PV panel, should there be any power failure from either component the overall power will not be compromised as it will be isolated and the rest of the system will keep working to its highest potential. With string inverters should a failure occur, the power of the whole system will be reduced meaning that a significant loss in energy will be seen.
Panel Positioning
It is vital that the position of PV panels is considered for maximum results. This means that potential shading and obstruction should be taken into account, thus to ensure the end-user receives an efficient supply of energy and this means that some panels may be positioned in a different direction. For projects like this, microinverters are recommended, as they work on panel for panel basis, thus optimising results. String inverters require all panels in the row to be in the same position – these are ideal for larger projects where roof space and shading aren’t an issue.
Maintenance
Of course, should a failure happen the system will need to be maintained and checked over. In the case of microinverters, this could be a little difficult as each inverter (connected to each panel) will have to be checked, which can be time consuming. With a string inverter (or set of them), it is a little more simple as they are installed near the main electricity supply so maintenance is much easier.
Warranty
Microinverter warrantees are extending and many now match the performance warranty of solar PV panels up to 30 years, however string inverters have a warranty of up to 10 years, meaning a system would need updating more often.
Comorin Solar has a number of inverters, both string and micro, to suit any project. And, with a selection of solely Tier one modules from some of the world’s renowned PV brands, you’ll be rest assured you can give you customers the best solar installation possible.
