Residential Solar Market Size, Share, Opportunities, And Trends By Panel Type (Monocrystalline, Polycrystalline, Thin Film), By Mounting Type (Roof Top Mounted, Ground Top Mounted, Others), By Area (Urban, Rural), And By Geography - Forecasts From 2023 To 2028

The residential solar market was valued at US$61.177 billion in 2021.

The residential solar market is predicted to show strong growth during the forecast period. Residential solar energy involves harnessing the sun's clean, renewable energy to generate electricity for households and apartment complexes. Residential solar energy systems can be either roof-mounted, adhering to the structure of the home, or ground-mounted, standing independently on the property. The decline in solar panel costs, proactive government initiatives, and progressive technological advancements collectively act as key drivers propelling the growth of the residential solar industry.

The falling cost of solar panels bolsters the residential solar market growth.

The declining cost of solar panels is a major factor propelling the growth of the residential solar market. Over the years, advancements in technology, increased production capacity, and improved economies of scale have significantly reduced the cost of solar panels. This price reduction has made solar energy more affordable for the average homeowner and with solar power becoming increasingly cost-competitive compared to traditional electricity sources, it is now an economically viable choice for a larger segment of the population. For instance, in April 2022, the cost of domestic solar modules produced by Original Equipment Manufacturers (OEMs) experienced a reduction of 10%.

Government initiatives drive the residential solar market expansion.

Government-led initiatives have been a significant driver in the growth of the residential solar industry. Favorable policies such as tax incentives, rebates, and subsidies have lowered the financial burden of installing solar panels, making them more accessible to a larger portion of the population. For instance, in 2023, the Indian government launched a subsidy program exclusive to residential homes. Under this initiative, households installing solar rooftop systems with a capacity between 1kW to 3kW are eligible for a 40% subsidy. Meanwhile, for larger installations with capacities ranging from 4kW to 10kW, a 20% subsidy is provided.

Technological advancement drives residential solar market growth.

Technological advancements in solar technology and storage systems are significantly propelling the growth of the residential solar market. Improvements in photovoltaic technology have not only led to more efficient and durable solar panels but have also reduced costs, making solar power increasingly affordable for homeowners. Concurrently, the advent of advanced solar storage systems, like high-capacity lithium-ion batteries, allows for the storage and use of solar-generated electricity even during periods of low sunlight or during the night. This has amplified the utility and reliability of solar power for residential use. For instance, in 2023, Sungrow introduces its cutting-edge all-in-one residential solar-storage-EV charging solution, now featuring an integrated AC EV charger alongside the 3-phase hybrid inverter and battery system for home.

North America is projected to dominate the residential solar market.

North America is expected to account for a significant share of the market due to proactive government initiatives and substantial investments in renewable energy infrastructure. The supportive regulatory environment, aggressive investment, and technological progression have positioned the region at the forefront of the residential solar market. For instance, in June 2023, the Biden-Harris administration initiated a $7 billion Solar for “All Grant Competition” aimed at funding residential solar programs designed to reduce energy costs for families. This ambitious venture underscores the administration's commitment to expanding access to affordable, clean energy for households across the nation. Also, in June 2023, Bright secured $31.5 million in Series C financing, a critical step towards broadening its reach in delivering solar power to households and enterprises throughout Mexico.

Intermittent energy production may restrain the residential solar market.

The ability of solar panels to produce energy is directly dependent on sunlight, creating a challenge for energy generation during cloudy conditions or nighttime. Although there are innovative energy storage solutions, such as advanced battery systems, they are an additional investment over the already substantial initial cost of the solar panel system itself. This elevated entry cost can potentially discourage homeowners from adopting solar energy, especially those in regions with less predictable sunlight or households on a tighter budget. Furthermore, these storage systems also necessitate space and may require maintenance, adding to the complexity and potential costs of the solar energy setup.

Key Developments

• January 2023: Tata Power Renewable Energy Ltd. (TPREL) announced the establishment of India’s first residential group captive solar plant. This pioneering initiative stems from a signed agreement with Vivarea Condominium, a residential society in Mumbai, to provide solar power. A novel undertaking, the project will see a 3.125 MW solar plant being established at Himayatnagar, Maharashtra, to furnish society with sustainable, clean energy, marking a significant stride in India's renewable energy landscape.
• December 2022: Blackstone and Rivean Capital finalized the acquisition of Esdec Solar Group B.V., a key player in the solar industry. Esdec is recognized for its development and supply of professional solar rooftop mounting solutions, catering to a diverse customer base that includes the residential, commercial, and industrial sectors. This acquisition underscores both Blackstone's and Rivean Capital's strategic investments in the renewable energy landscape.
• June 2022: The World Bank Board of Executive Directors approved additional funding of $165 million to bolster India's residential sector in adopting rooftop solar systems, to promote the affordability of solar energy. This financial support seeks to accelerate the adoption of sustainable energy solutions, thereby contributing to India's broader renewable energy goals and fostering a greener and more sustainable future for the nation.
• October 2021: SunPower successfully acquired the residential solar company, Blue Raven, for $165 million. This strategic acquisition is set to bolster SunPower's reach, particularly in underpenetrated regions including the Northwest and Mid-Atlantic. As a result, the company will be better positioned to serve more customers, enhancing its footprint in the residential solar market.
