6 FAQs about [Why do photovoltaic inverters need boosting ]
Why do solar PV inverters use a lower capacitance value?
Since capacitor value directly depends on the maximum power, most of the inverters use electrolytic capacitors parallel to the PV module. This element reduces the lifetime and increases the cost of the photovoltaic system , . Thus, the solar PV inverter desires to use reduced capacitance value.
How a solar PV inverter has a higher lifetime?
Higher lifetime can be obtained by using film capacitors in boost inverters. Apart from that, source side electrolytic capacitor is replaced by multiple ac film capacitors for energy storage purpose as shown in Fig. 10, Fig. 12. Thus, boost inverters shows the desired characteristics of solar PV inverter. Fig. 21.

Why do multilevel inverters need a boosting feature?
In conventional multilevel inverter topologies, the number of devices increases with the increase of the number of output voltage levels, which in turn makes circuitry bulky and costly. Further, the boosting feature of the input voltage is also necessary for the application of multilevel inverters with renewable energy.
Why do solar PV inverters use DC link inductors?
This element reduces the lifetime and increases the cost of the photovoltaic system , . Thus, the solar PV inverter desires to use reduced capacitance value. Boost inverter uses dc link inductors to maintain a constant current, thus less capacitance value is used in dc link.
