Solar EPC Market Report 2026

The solar epc market size has grown strongly in recent years. It will grow from $246.41 billion in 2025 to $259.58 billion in 2026 at a compound annual growth rate (CAGR) of 5.3%. The growth in the historic period can be attributed to growth in large scale solar project development, early adoption of photovoltaic technologies, expansion of commercial and industrial solar installations, rise in government subsidies for solar infrastructure, increasing focus on reducing fossil fuel dependency.

The solar epc market size is expected to see strong growth in the next few years. It will grow to $317.6 billion in 2030 at a compound annual growth rate (CAGR) of 5.2%. The growth in the forecast period can be attributed to rising investment in utility and floating solar projects, growing demand for rooftop solar installations, advancements in tracking and mounting technologies, expansion of smart grid and solar integration solutions, increasing need for scalable and cost efficient solar epc services. Major trends in the forecast period include growing deployment of utility scale solar epc projects, rising adoption of floating solar epc installations, increasing use of single and dual axis tracking systems, expansion of rooftop solar epc in residential and commercial sectors, shift toward integrated epc models for faster project delivery.

The growing demand for renewable energy sources is expected to drive the growth of the solar EPC (Engineering, Procurement, and Construction) market. Renewable energy refers to energy derived from naturally replenishing resources, such as sunlight, wind, rain, tides, waves, geothermal heat, and biomass. Solar EPC plays a crucial role in the implementation of solar energy projects by offering a comprehensive approach that includes design, procurement, and construction. This method helps optimize costs, ensure quality, and streamline the entire process, making it essential for the development and expansion of renewable energy, particularly solar power. For instance, in September 2024, according to data published by the UK Department for Energy Security and Net Zero, renewable energy accounted for 51.6% of total energy generation in Q2 2024, marking a 9.9 percentage point increase compared to Q2 2023. Solar PV accounted for three-quarters of these new installations. Therefore, the rising demand for renewable energy sources is fueling the growth of the solar EPC market.

Major companies operating in the solar EPC market are focusing on developing innovative solutions such as end-to-end digital lending to simplify rooftop solar project financing, accelerate adoption, and improve accessibility for both residential and commercial customers. End-to-end digital lending refers to a fully digital, technology-driven loan process that manages everything from application and credit assessment to disbursement and repayment. For instance, in July 2025, Fibe, an India-based digital lending platform, launched rooftop solar financing in Bharat, offering collateral-free loans, rapid digital approvals, and partnerships with over 100 solar EPC companies to expand residential solar installations across Tier 2 and Tier 3 cities. This solution helps households access sustainable energy while supporting EPC companies in scaling installations efficiently.

In July 2024, Complete Solar, Inc., a U.S.-based solar technology, services, and installation company, acquired Core Energy, LLC, for an undisclosed amount. Through this acquisition, Complete Solar aims to expand its installation footprint, strengthen project execution capabilities, and integrate Core Energy’s operational team and expertise to deliver more efficient and large-scale solar energy projects. Core Energy is a US-based solar EPC company that provides Solar EPC services.

Major companies operating in the solar epc market are Bechtel Corp., Siemens Gamesa Renewable Energy S.A., Adani Group, Canadian Solar Inc., Xylem Inc., First Solar Inc., Black & Veatch Holding Company, Blattner Energy, Renewable Energy System Ltd., Juwi AG, Sterling and Wilson Pvt. Ltd., Anesco Ltd., Vikram Solar Limited, DEPCOM Power Inc., Q Cells, Core Development Group, Alas Solar System LLC, Sunel Group, Enerparc AG, Greenspark Solar, BELECTRIC Solar & Battery Holding GmbH, Strata Solar LLC, Hild Energy Pvt.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on imported solar modules, inverters, and mounting structures have increased overall EPC project costs, leading to delays and budget challenges, particularly for utility scale and commercial installations in regions such as Asia Pacific, North America, and Europe. These tariffs disproportionately impact photovoltaic EPC projects dependent on high efficiency imported components. However, domestic manufacturing is gaining momentum as tariffs encourage localized production, supply chain diversification, and long term sector resilience, partially offsetting cost escalations.

The main mounting types of solar EPC are ground, rooftop, and floating. Rooftop refers to the installation of solar power systems on the roofs of buildings that involves designing, installing, and maintaining solar power systems on rooftops. The various technologies include concentrated solar power and photovoltaic, which are used by several end-users, such as residential, commercial, industrial.

The solar EPC (engineering, procurement, and construction) refers to the process of designing, planning, and installation of solar power plants or systems, including engineering, procurement, and construction services. This involves sourcing and acquiring all the necessary materials, equipment, and components required for the solar project.
