Utility-Scale Solar Balance of System (BoS) Market Forecasts to 2034 – Global Analysis By Component (Mounting & Tracking Systems, Inverters, Cabling & Wiring, Switchgear, Transformers, and Protection Systems, Monitoring & Control Systems, Energy Storage I

According to Stratistics MRC, the Global Utility-Scale Solar Balance of System (BoS) Market is accounted for $18.15 billion in 2026 and is expected to reach $38.90 billion by 2034 growing at a CAGR of 10.0% during the forecast period. The Balance of System (BoS) in utility-scale solar power plants refers to every element except the photovoltaic panels that is required to build and run the project. This includes electrical equipment such as inverters and transformers, structural components like mounting systems and trackers, wiring, monitoring platforms, and all civil and installation works. In large solar farms, BoS accounts for a major portion of capital expenditure and plays a key role in plant efficiency, durability, and grid integration. Advancements in smart inverters, tracking systems, and automation are helping lower costs, accelerate construction, and maximize overall plant output.

According to the International Energy Agency, solar PV accounted for ~75% of global renewable capacity additions in 2023, with China contributing ~60% of global PV installations.

Market Dynamics:

Driver:

Rapid expansion of utility-scale solar installations

The accelerating development of utility-scale solar plants across global energy markets is strongly boosting the Balance of System (BoS) market. Many countries are prioritizing large solar projects to achieve decarbonization goals and diversify power generation. As solar parks increase in size and number, the requirement for non-module components—including power electronics, mounting structures, electrical wiring, substations, and control systems—rises substantially. In addition, large projects involve complex construction and grid-integration activities, further increasing BoS demand. This steady increase in utility-scale solar deployment directly translates into higher investment and sustained growth for the BoS market.

Restraint:

High initial capital and installation costs

The significant upfront investment required for Balance of System (BoS) components poses a major challenge to the utility-scale solar market. Non-module elements such as electrical equipment, tracking systems, foundations, and grid infrastructure represent a large share of project capital costs. Expenses related to construction, logistics, skilled labor, and site development further increase financial pressure. In highly competitive power markets, developers may struggle to absorb these costs while maintaining acceptable returns. This financial burden can slow project approvals, restrict adoption of advanced BoS technologies, and act as a barrier to rapid expansion of utility-scale solar installations.

Opportunity:

Advancements in digital monitoring and smart BoS solutions

The growing use of digital technologies in utility-scale solar plants opens new opportunities for the Balance of System (BoS) market. Smart monitoring systems using sensors, cloud platforms, and analytics enhance operational visibility and enable predictive maintenance. These solutions improve reliability, extend equipment life, and reduce operational expenses. Developers increasingly prioritize intelligent BoS components that support automation and remote control. As solar assets become more data-driven, demand rises for advanced digital BoS solutions, allowing suppliers to differentiate their offerings and generate recurring revenue through software and performance optimization services.

Threat:

Policy uncertainty and changes in government incentives

Unstable renewable energy policies represent a serious risk to the utility-scale solar Balance of System (BoS) market. Large solar projects rely on long-term policy support to remain financially viable. Unexpected changes in subsidies, tax credits, or procurement frameworks can disrupt project pipelines and reduce installation volumes. This uncertainty makes developers cautious and limits capital allocation. For BoS suppliers, fluctuating policy environments complicate capacity planning and investment decisions. As a result, inconsistent government support can significantly slow market expansion and weaken confidence across the utility-scale solar value chain.

Covid-19 Impact:

COVID-19 significantly influenced the utility-scale solar Balance of System (BoS) market by disrupting global supply chains and slowing project execution. Temporary shutdowns of factories and logistical bottlenecks caused delays in the delivery of critical BoS components, while workforce constraints reduced construction efficiency at project sites. Financial uncertainty and shifting government priorities also postponed new utility-scale solar investments. These factors collectively slowed market growth during the peak of the pandemic. Despite these challenges, the easing of restrictions and strong post-pandemic renewable energy commitments helped restore project activity, enabling the BoS market to recover progressively.

The mounting and tracking systems segment is expected to be the largest during the forecast period

The mounting and tracking systems segment is expected to account for the largest market share during the forecast period due to their critical structural and performance functions. These systems physically support solar panels and, in many cases, actively track the sun to enhance power generation throughout the day. Large solar plants require significant quantities of mounting hardware, foundations, and mechanical assemblies spread across wide sites. The complexity of installation, material usage, and their direct influence on plant efficiency and durability make mounting and tracking systems a major contributor to overall BoS value in utility-scale solar developments.

The project developers / EPCs segment is expected to have the highest CAGR during the forecast period

Over the forecast period, the project developers / EPCs segment is predicted to witness the highest growth rate as these stakeholders drive end-to-end project delivery. Developers and EPC firms coordinate system design, component selection, construction, and grid connection, making them key adopters of advanced BoS technologies. Increasing project scale, tighter margins, and the need for optimized performance are pushing EPCs to adopt innovative mounting systems, smart inverters, and digital monitoring tools. Their expanding scope and influence across the solar value chain are accelerating demand growth, resulting in higher growth momentum for this segment.

Region with largest share:

During the forecast period, the Asia Pacific region is expected to hold the largest market share, supported by aggressive solar expansion and favorable policy frameworks. Large solar installations across the region generate strong demand for structural systems, power electronics, electrical components, and grid infrastructure. Cost advantages from local manufacturing, skilled engineering services, and well-established supply networks strengthen regional competitiveness. Rising power consumption, renewable energy targets, and increasing integration of advanced solar technologies continue to drive BoS requirements. These factors collectively position Asia-Pacific as the leading contributor to global utility-scale solar BoS market activity.

Region with highest CAGR:

Over the forecast period, the Middle East & Africa region is anticipated to exhibit the highest CAGR, supported by large-scale solar deployment and energy diversification strategies. Countries in the region are actively developing utility-scale solar plants to address rising electricity demand and reduce carbon intensity. These projects require extensive BoS infrastructure, including tracking systems, electrical components, and grid connection facilities. Favorable policy reforms, declining solar costs, and growing interest from international developers are accelerating project activity. As utility-scale solar adoption increases, demand for BoS solutions is expected to grow at a rapid pace across the region.
