Different components of the solar value chain account for different revenue generation as a significant portion constitutes panels followed by inverters and batteries. The value chain complexity offers little room for technical differentiation of solar devices as the efficiency of these devices is relatively high. Residential Solar PV Inverters are an integral part of the larger solar system. These inverters convert the DC electricity to the alternate current and hence determine the efficiency of the whole solar system. Residential Solar PV Inverters are available with distinct characteristics and features and take into account different factors affecting solar system production. Some of the critical factors include shading, roof orientation, roof inclination, summer vs winter production, tilting panels, and many other factors that result in the required output. Renewable power generation cost has witnessed a very steep decline and in the current scenario is very competitive to meet the need for new capacity. For instance, solar photovoltaics have resulted in a decrease of approximately ~72% for the leveled cost of electricity (LCOE) which is one of the highest cost reductions compared to other renewable energy technologies such as wind. This fall in the prices of solar power generation came with the reduction of installation costs for solar modules, cells, inverters, and related equipment. The COVID-19 pandemic hindered the market growth of PV inverters globally owing to factors such as disruption in the supply chain. Furthermore, the demand has been reduced for the PV inverter from residential and commercial End-Uses due to restricted new construction activities and due to the diversion of available funds by residential and commercial End-Uses to sustain during the COVID-19 pandemic.

Key Market Challenges

In traditional PV systems, PV panels, wires, and other equipment are energized with high DC voltages. These high DC voltages pose risks to installers, maintenance personnel, and firefighters. Solar inverters with PV arrays involve high DC voltages, making it difficult to isolate DC electric devices from PV arrays using DC isolation switches. When PV modules are connected in series, they create a high voltage, which can be dangerous for installers during the system installation. Under the condition of short-circuit current, there is a possibility of electric arcs, which can result in fire and a resulting threat to people in the vicinity of a PV system. These DC arcs are difficult to extinguish, posing a risk to firefighters. The fire can damage DC cables in PV arrays, thereby leading inverters to shut down automatically while manually isolating DC cables and other components. Safety mechanisms mandated by the National Electric Code (NEC) and the Electrical Safety Authority (ESA) of the US do not eliminate all risks, which hamper the growth of the inverter market.

Segmental Insights

Type Insights

A central inverter is a large grid feeder. It is often used in solar photovoltaic systems with rated outputs over 100 kWp. Floor or ground-mounted inverters convert DC power collected from a solar array into AC power for grid connection. These devices range in capacity from around 50kW to 1MW and can be used indoors or outdoors. A central inverter consists of one DC-AC conversion stage. Some inverters also have a DC-DC boost stage to increase their MPP (maximum power point) voltage range. Low-frequency transformers are sometimes used to boost the AC voltage and provide isolation at the output. However, this reduces efficiency and increases the inverter’s size, weight, and cost. A central inverter typically has a maximum input voltage of 1,000V. However, some newer central inverters already come with 1,500V input voltage. These inverters allow PV arrays based on a maximum voltage of 1,500V, requiring fewer BOS (balance of system) components. Therefore, the growing demand for electricity, the government’s efforts to decarbonize the power sector, and the declining costs of central inverters are expected to drive the segment’s growth during the forecast period.
