Photovoltaic inverter inventory

What software is used to model a PV inverter inventory?

Inventories were modeled using openLCA software (GreenDelta 2023) and the ecoinvent 3.9 life cycle inventory database (FitzGerald and Sonderegger 2022). Additionally, primary data were collected from a commercially available 2.7 MWac inverter to provide an updated inventory for utility-scale PV inverters.

Why are hybrid inverters becoming a standard for residential solar PV systems?

With the decline in financial incentives for solar power exporting to the grid and increasing awareness of self-consumption in key residential markets including Europe, California, and Australia, hybrid inverters, which combine solar and energy storage conversion, are becoming the standard for residential solar PV systems in many markets.

What is the empirical inverter inventory?

The empirical inverter inventory was collected from an installed preoperational inverter and built using material inputs and analogous components from the ecoinvent life cycle inventory database.

Which PV inverter vendors shipments grew the most in 2022?

The top five vendors – Huawei, Sungrow, Ginlong Solis, Growatt, and GoodWe – shipped more than 200 GWac and accounted for 71% of total global PV inverter shipments in 2022, growing 8% from 2021. Huawei’s shipments saw a significant increase of 83% in 2022 compared to 2021, while Sungrow’s shipments expanded 56% in the same period.

What is energy storage inverter?

Integrated solutions that have batteries and power conversion systems (PCS) or as we call it at S&P Global Commodity Insights – ‘energy storage inverter’ combined as a complete device simplify installation to under 30 minutes and are expected to gain market share in 2025.

What are the primary manufacturing options for PV modules?

In this LCA, we considered six primary manufacturing options: three based on an imported PV module supply chain (comparing low-carbon imports, high-carbon imports, and average imports), and three based on a potential domestic PV module supply chain (comparing low-carbon U.S. regions, high-carbon U.S. regions, and average U.S. regions).
