The region is also experiencing rapid growth due to the declining costs of photovoltaic components and the expansion of utility-scale solar projects. This surge in solar installations is increasing the demand for BOS components such as inverters, mounting structures, wiring, and monitoring systems. Both the U.S. and Canada are witnessing heightened activity in solar energy infrastructure, supported by strong private sector participation and a growing number of public-private partnerships.

Moreover, North America's focus on sustainability and decarbonization is fueling long-term growth in the solar sector. With clear targets for carbon neutrality and a transition toward clean energy, the region is prioritizing solar energy as a key solution. Technological advancements, along with a robust local supply chain, are also enhancing the competitiveness of BOS solutions in North America. These combined factors are solidifying the region’s position as the fastest-growing Solar PV BOS market globally.

A significant increase in utility-scale installations across the U.S. and Canada is driving large-scale demand for mounting systems, inverters, wiring, and other BOS elements.

The rise of utility-scale solar projects is playing a big role in boosting the Balance of System (BOS) market across North America. Unlike smaller residential installations, these larger projects need more complex infrastructure, which includes advanced mounting systems, high-capacity inverters, durable electrical wiring, monitoring technologies, and components for connecting to the grid. As utility companies and independent power producers (IPPs) look to diversify their energy sources and meet carbon reduction goals, they are increasingly investing in large-scale solar installations.

In the U.S., states like California, Texas, and Florida are at the forefront of this utility-scale solar development. Canada is also making strides, especially in provinces like Alberta and Ontario. These large projects not only generate renewable electricity at a lower cost per watt but also enhance grid stability and energy security. Plus, they often come with long-term power purchase agreements (PPAs), which provide financial stability and make them more attractive for investors.

Given the complexity and size of these installations, the demand for BOS components is growing, driving significant growth in this market across North America. As more utility-scale solar farms are planned and put into operation, we can expect continued momentum in the BOS sector.

The declining cost of PV modules and BOS components is making solar power more competitive with traditional energy sources, encouraging wider deployment.

The ongoing decline in the cost of solar technology is a key driver for the Solar PV Balance of System (BOS) market in North America. Over the past decade, the average price of photovoltaic (PV) modules has decreased significantly due to advancements in technology, economies of scale, and increased competition. This reduction in cost extends beyond just the modules to include BOS components such as inverters, racking systems, and installation hardware.

Lower costs make solar installations more accessible for residential, commercial, and utility-scale customers, leading to broader adoption. As more projects are initiated, the demand for high-quality and efficient BOS solutions naturally increases. Additionally, reduced installation and labor costs—partly due to more modular and standardized BOS designs—have contributed to lowering overall system costs.

The affordability of solar energy is making it increasingly competitive with traditional fossil fuels, accelerating its integration into the mainstream energy mix. Consequently, the BOS market benefits from a positive feedback loop: as solar adoption rises due to falling prices, the demand for BOS components grows, which in turn encourages further innovation and cost reduction in BOS technologies across North America.

National and regional commitments to achieve net-zero emissions by 2050 are pushing investment in renewable energy, especially solar power.

North America’s dedication to reducing greenhouse gas emissions is a significant driver for the growth of the Solar PV Balance of System (BOS) market. Both the U.S. and Canada have committed to achieving net-zero carbon emissions by 2050, aligning their national energy strategies with climate goals established under frameworks like the Paris Agreement. In this context, solar power is crucial for the transition from fossil fuels to cleaner energy sources. Governments at the federal, state, and provincial levels are incorporating solar deployment targets into their energy roadmaps, which increases the demand for BOS infrastructure.

Utilities are retiring coal-fired power plants and replacing them with solar farms, which require extensive BOS installations such as grid-tied inverters, power optimizers, combiner boxes, and durable mounting systems. Additionally, environmental regulations and corporate sustainability initiatives are creating further pressure to adopt low-emission technologies, driving investments in solar energy. This policy-driven momentum is leading to a higher demand for efficient and cost-effective BOS components that can support the rapid scaling of solar power capacity. As these objectives remain top priorities in the coming decades, the BOS market in North America is well-positioned for steady, long-term growth.
