As the global “carbon neutrality” goals advance, China’s PV industry has seen explosive growth in 2024. According to data from the National Energy Administration, new PV installations in the first half of 2024 reached 102.48 GW, of which commercial and industrial (C&I) PV added 37.03 GW, up 90.5% year-on-year. In this green energy revolution, the 110kW C&I and ground-mount PV solution – with its optimal power rating, high system reliability, and attractive payback period – is becoming a core engine for decarbonization across thousands of industries.

I. Market Drivers: Policy Incentives and Electricity Demand

In 2024, policies for distributed PV have been continuously refined, with numerous supportive measures from national and local governments, creating a favorable environment for C&I ground-mount projects.

At the national level, a new administrative measure for distributed PV is expected to be released, clarifying the classification and management of C&I distributed solar. Ground‑mounted C&I distributed PV stations are now a key focus – enterprises using their own land (including ponds and water surfaces) can build PV stations, provided their annual electricity consumption is at least 50% of the station’s generation, to enjoy relevant incentives. Also, electricity consumed on-site is exempt from government funds such as the renewable energy surcharge.

At the local level, economically leading provinces like Guangdong, Zhejiang, and Jiangsu are leading the way with PV subsidies. As of now, 70 local governments still offer PV subsidies covering C&I projects. Zhejiang Province has 28 districts with subsidy policies, with the highest feed‑in tariffs reaching RMB 0.45/kWh in Haishu District and Yuyao. Guangdong Province has issued its “Action Plan for High‑Quality Development of Distributed PV”, and Shenzhen’s Luohu District offers a subsidy of RMB 0.25/kWh for benchmark conventional PV projects. These policy effects significantly shorten the payback period for C&I PV projects and strongly support the accelerated deployment of 110kW solutions.

II. Core Technology Evolution of the 110kW Inverter

The 110kW inverter has become a popular choice in the C&I segment thanks to multiple technological breakthroughs. Key performance features of mainstream three‑phase string inverters at this rating include:

High efficiency: Leading products achieve maximum conversion efficiency of 98.6%, with 6–10 MPPT channels, each supporting currents up to 32A–42A. This ensures perfect compatibility with 182mm and 210mm large‑format wafers, significantly reducing yield losses caused by shading or orientation mismatches between strings. For example, the AISWEI ASW 80‑110kW LT series uses an industry‑leading 10‑MPPT design (max 32A per MPPT) and features intelligent global scan technology to boost generation in multi‑shading scenarios. The Huawei 110kW string inverter has proven its performance in many projects. Inverenergy’s 110kW string inverter can connect up to 12 strings of 210 modules without power or current limitations, making it a hot seller.

Reliability & adaptability: Most 110kW inverters come with IP66 protection, capable of operating reliably in harsh environments such as high temperature, high humidity, and high salt fog. The GoodWe GT series also includes AFCI 3.0 DC arc fault protection with AI algorithms, extinguishing arcs within 0.5 seconds, greatly enhancing system safety. For smart O&M, inverters are increasingly adopting touch‑free designs with LED + APP interaction, supporting remote commissioning, I‑V scanning diagnosis, and string‑level precision monitoring, drastically reducing O&M costs.

System compatibility: 110kW inverters support aluminum cable connection (up to 240mm²), eliminating the need for copper cables on the AC side; the DC side is typically fuse‑free, avoiding extra O&M expenses and further reducing total lifecycle costs.

III. Ground‑Mount Racking Systems: A New Breakthrough for Cost and Efficiency

In addition to inverters, ground‑mount racking systems have seen significant innovations in 2024. Manufacturers have greatly reduced installation costs and time through modular design and rapid‑assembly technologies. For example, Clenergy’s PVezRack® SolarTerrace Ikon (ST Ikon) – an innovative ground‑mount system – simplifies on‑site installation with fewer components, significantly lowering labor and logistics costs. It can be installed by just one technician, making it ideal for high‑labor‑cost markets like Europe. Its integrated grounding system eliminates the need for additional grounding components, further improving safety and installation efficiency, while the modular design flexibly adapts to various terrain conditions.

These trends perfectly address the C&I ground‑mount sector’s demands for high efficiency, safety, and economy, providing solid support for the overall cost‑effectiveness of 110kW PV solutions.

IV. Case Studies: Demonstrating the Green Value of 110kW Solutions

In 2024, 110kW inverters have been deployed at scale in multiple C&I ground‑mount and rooftop projects, effectively driving green transformation across various industries.

Case 1: Jiǔquán Xīndá Near‑Zero Carbon Industrial Park

In September 2024, the 5.98 MW rooftop distributed PV project of Jiǔquán Xīndá Energy Development Co., Ltd. in Gansu Province entered grid‑connected trial operation. Located in the Jiǔquán Economic and Technological Development Zone, the project uses Huawei’s Smart PV Solution 2.0, featuring 110kW string inverters and ultra‑high‑power modules. It fully addresses challenges such as limited rooftop space, complex shading, and high O&M requirements. After full operation, annual generation is expected to reach 10.07 GWh, reducing CO₂ emissions by about 3,494 tons per year and saving RMB 3.1 million in electricity costs in the first year. It has become a benchmark near‑zero‑carbon development project in the Dongdatan PV industrial park and across northwest China.

Case 2: Hubei Xīn Xīng Quánlì 4.46 MWp Ground‑Mount PV Project

Hubei Xīn Xīng Quánlì Company launched a 4.46 MWp ground‑mount distributed PV project in response to national “dual carbon” goals. Using advanced N‑type 580Wp monocrystalline silicon bifacial modules and high‑efficiency 110kW string inverters, all generated electricity is consumed on‑site for production. The project saves over 2,000 tons of coal and reduces CO₂ emissions by approximately 3,831 tons per year, with annual electricity savings exceeding RMB 2 million. The successful implementation not only reduces the company’s dependence on traditional energy but also serves as a green model for state‑owned enterprises in the region.

Case 3: Changshu Xiangyi Property 482 kW Rooftop PV Project

Changshu Xiangyi Property Management Co., Ltd. built a 482.12 kW distributed PV project on idle rooftop space, adopting CSI Solar 110kW inverters and high‑efficiency bifacial modules. Based on local sunshine conditions, the project is expected to generate a total of 11.69 GWh over 25 years, equivalent to reducing CO₂ emissions by 10,200 tons and planting about 558,000 trees, effectively supporting the company’s zero‑carbon development path.

Case 4: Shenzhen Bao’an Airport Floating PV Demonstration Project

In October 2024, a floating PV generation demonstration project at Shenzhen Bao’an International Airport was completed and put into operation – total capacity 417.6 kW, covering about 3,000 m². The entire project uses Inverenergy 110kW string inverters, leveraging their high MPPT current capability and high protection rating to cope with challenging airport‑specific conditions such as moisture, corrosion, and high temperatures on the water surface, maximizing generation. Expected annual output is about 500,000 kWh, reducing CO₂ emissions by roughly 226 tons, offering a highly valuable reference for high‑value scenarios like airports.
