Solar Micro Inverter Market Drivers:

Decreasing Hardware Costs

The costs associated with the hardware components used in solar micro inverters has witnessed a significant decrease in the past few years. Manufacturers have been able to achieve substantial economies of scale due to the rising demand for solar PV installations across both the residential and commercial sectors globally. This has enabled them to invest heavily in research and development activities to make the micro inverters more efficient using less material and lowering manufacturing costs. The semiconductor chips and Integrated Circuits (ICs) used in micro inverters occupy much smaller real estate compared to traditional string inverters, translating to lower bill of material costs. Moreover, innovations in power conversion design have increased power densities manifold, further bringing down hardware costs.

Integration of newer high-efficiency power switching devices like silicon carbide metal oxide semiconductor field effect transistor MOSFETs and Insulated-Gate Bipolar Transistor IGBTs along with advanced gate driver modules have maximized power outputs. This has allowed manufacturers to reduce the number of components needed in each unit to deliver the same power capacity. With steady reduction in pricing achieved over the past few years, micro inverters have become much more affordable for solar installers and homeowners. The payback period has shortened significantly, making them an attractive proposition even in price-sensitive emerging solar markets. Additionally, localized manufacturing especially in China and Southeast Asia has ensured greater supply assurance and economies of scale benefits are passed on the end customers. Overall, plummeting hardware costs is a major driver increasing the competitiveness of solar micro inverters against traditional string inverters.

Market Concentration and Competitive Landscape

One of the key advantages of solar micro inverters lies in their ability to maximize energy harvest from each solar PV module individually. Traditional string or central inverters have limitations that portions of strings experiencing shade or underperformance are unable to contribute their full potential. However, micro inverters solve this issue elegantly as they monitor and optimize power conversion for every single solar panel separately. This allows much higher solar energy utilization even in installations where partial shade is unavoidable such as rooftop systems. Advanced monitoring features integrated into newer micro inverter models have added to this value proposition. Homeowners and commercial building managers can keep a tab on performance of each solar module remotely via mobile or web-based dashboards.

Real-time production data collated module-wise helps in proactively detecting faults and underperforming panels. System administrators can locate issues promptly and schedule maintenance well in advance to prevent losses.
