What are the benefits of a Micro-Inverter solar system?
Micro-inverters are useful and recommended when there are shading issues across the solar panels or where you need panels to face different directions because of the roof design.
micro-inverters allow each panel to operate on its own, so if a single panel or some panels are in shade it will not affect the output as the panel in sunlight will work to its full capacity.
Some roofs are small and can fit only a few panels. Other roofs point in differing directions. To get efficient solar system output in such situations, a micro-inverter will be most suitable for the solar installation. With the use of micro-inverters you can have the panels oriented into two or more different directions, while string inverters require several panels to be facing in the same direction together.
Micro inverters also allow the performance of every panel to be monitored individually. In the case of a system fault or poor performing panel, micro inverters enable faster identification and repair.
Micro inverters may also reduce down time from breakdown. For example, if a string inverter stops working the whole solar system stops working and produces no power. If a micro inverter stops working, only the individual panel stops working and the rest of the panels in the system should still work and be unaffected.
Micro inverters also allow for expandability as you can add additional panels one at a time with another micro inverter. You can also use different brand or size panels in the system. With a string inverter it can be harder to expand a system, as it is dictated by the size of the inverter and additional panels need to be the same or almost identical in specifications to the existing panels.
Micro inverters will also allow for panels to be added at a later date as any number of panels can be added with a micro inverter. With a string inverter, only an identical panel can be added and only if the string inverter has the extra capacity/ room.
