Floating solar farms installed in water are gaining traction as they avoid soil barriers and can increase efficiency due to water owing to the coolness it provides. EPC companies are increasingly providing solutions for floating solar projects, especially in countries with limited land availability.

Solar EPC Market Driver

Technological Advancements in Solar Technologies to Propel Market Growth

Advances in advanced photovoltaic (PV) cell technologies, such as passive-emitting back-cell (PERC) and heterojunction technology (HJT), have led to higher-efficiency panels. These panels can generate more energy from site one of the top and reduce installation costs. Solar is a viable option in communities where space is limited; efficiency also makes solar projects attractive in the market size, increasing the demand for EPC services.

Bifacial panels capture sunlight from both sides, increasing power output by up to 20%. They are especially useful in reflective environments such as areas of snow or sand. Innovative efficiencies mean lower costs per kilowatt-hour (kWh) of electricity produced, making solar projects more economically attractive and commanding larger loads, encouraging the establishment and leading to demand for EPC expertise.

Solar EPC Market Restraint

High Upfront Investment Cost May Restrain the Market

Even as solar equipment prices fall, large solar projects, including initial equipment, construction, and installation costs, remain significant; for small businesses or individual buyers, these upfront costs can be a considerable barrier, potentially slowing down market growth. Land acquisition for large-scale solar projects is difficult, especially in densely populated or expensive areas. Lengthy permitting processes, land use restrictions, and environmental assessments delay projects, increase costs, and discourage new installations.

Solar EPC Market Opportunity

Government Initiatives and Regulatory Support to Create Market Opportunity

Numerous governments are offering monetary incentives, subsidies, and supportive regulatory environments to encourage the adoption of solar energy. For example, the U.S. provides a 26% Investment Tax Credit (ITC) for solar installations, crucial in boosting market expansion. Regulatory bodies are starting to acknowledge the significance of incorporating energy storage alongside solar systems. This opens up more avenues for EPC companies to offer holistic solutions encompassing power generation and storage features. Countries globally are establishing ambitious renewable energy goals to aid in the fight against climate change, boosting the demand for solar EPC services.

• Impact of COVID-19 on the Solar EPC Market

Analysis By Technology

Based on technology, the market is divided into photovoltaic and CSP-based technology.

The photovoltaic segment is the largest segment in the solar EPC market. Over the last decade, the cost of photovoltaic modules has dropped significantly due to technological advancements and economies of scale in manufacturing. This has made solar power more affordable and accessible, boosting its adoption across residential, commercial, and utility-scale projects. The cost of building solar panels has steadily fallen, making photovoltaics the most expensive form of renewable energy.

The CSP segment is the second largest segment in the solar EPC market. CSP systems are generally more expensive and difficult to manufacture than photovoltaic systems. Larger components, such as glass or mirrors, are required to absorb sunlight onto a central receiver, increasing capital expenditure (CAPEX) and operational complexity.

Analysis By Application

Based on application, the market is divided into rooftop and ground-mounted solar panels.

The rooftop segment is the largest segment in the solar EPC market. The segment is expanding rapidly for several reasons, making it one of the most attractive and convenient locations for residential and commercial solar installations.

The ground-mounted solar panels segment holds the second-dominating market share. As technology improves and costs come down, the grounded block will continue to play an important role in meeting the global energy demand and contributing to clean energy infrastructure.

Analysis By End-User

On the basis of end-user, the market is divided into residential, commercial and industrial, and utility.

The residential segment holds the largest market share. Over the past decade, the cost of solar panels has dropped dramatically, making them more affordable for residents. This trend will continue, leading to the increased household adoption of solar energy.

The commercial and industrial segment is the second largest segment in the solar EPC market. Many commercial properties, especially apartment buildings or heavy-duty facilities, are increasingly turning to solar to reduce energy costs. Installing solar systems can reimburse businesses for a significant portion of their electricity bills, leading to significant long-term savings.

Regional Analysis
