DG ROOFTOP SOLAR PV MARKET OVERVIEW

The global dg rooftop solar pv market size is anticipated to be valued at USD 9.84 Billion in 2026, with a projected growth to USD 24.84 Billion by 2035 at a CAGR of 10.84% during the forecast from 2026 to 2035.

DG Rooftop Solar PV (Distributed Generation Rooftop Solar Photovoltaic) refers to the installation of solar photovoltaic (PV) systems on rooftops or other suitable spaces of individual homes, businesses, or institutions for the purpose of generating electricity locally. This electricity generation is distributed and consumed on-site, reducing the reliance on traditional grid-supplied electricity. DG Rooftop Solar PV is a form of distributed generation, meaning that electricity is generated close to where it is consumed. This reduces transmission and distribution losses and can enhance the reliability of the electricity supply. Solar panels are typically installed on the rooftops of buildings, including residential homes, commercial establishments, industrial facilities, and public institutions like schools and hospitals. The panels are mounted on racks or frames to capture sunlight. Solar PV panels use photovoltaic cells to convert sunlight into electricity. These cells are made of semiconductor materials that generate a direct current (DC) when exposed to sunlight.

DG Rooftop Solar PV systems can be designed to operate in conjunction with the electrical grid. Excess electricity generated during sunny days can be fed back into the grid, and when the sun is not shining, electricity can be drawn from the grid. Many regions have net metering policies in place, which allow owners of DG Rooftop Solar PV systems to receive credit for the excess electricity they generate and feed into the grid. This credit can offset their electricity bills. DG Rooftop Solar PV systems help reduce greenhouse gas emissions and dependence on fossil fuels, making them an environmentally friendly energy source. They also contribute to the transition to cleaner energy sources and a more sustainable energy future. In many countries, there are financial incentives and subsidies available to encourage the adoption of rooftop solar PV systems. These incentives may include tax credits, rebates, and feed-in tariffs.

KEY FINDINGS

COVID-19 IMPACT

Installation Delays to Hinder Market Growth

The COVID-19 pandemic has been unprecedented and staggering, with experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden decline in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The solar industry relies on a global supply chain for components such as solar panels, inverters, and mounting hardware. COVID-19 disruptions, including factory closures and transportation issues, led to delays in the production and delivery of solar equipment, which affected project timelines and increased costs. Lockdowns, social distancing measures, and health concerns during the pandemic led to disruptions in the installation of rooftop solar systems. Many installation teams faced delays, and some projects had to be postponed. The economic impact of the pandemic created financial uncertainty for individuals and businesses, making it more challenging for some to invest in rooftop solar PV systems. Financing options and access to capital for solar projects were affected.

LATEST TRENDS

Smart and IoT-Enabled Systems to Enhance Market Growth

Integration of energy storage solutions, such as batteries, with rooftop solar PV systems has been a growing trend. This allows users to store excess energy generated during the day for use during the night or during power outages, increasing energy independence and grid resilience. Rooftop solar systems are becoming smarter through the use of Internet of Things (IoT) technology. These systems can be monitored, controlled, and optimized remotely, leading to better performance, increased energy efficiency, and easier maintenance. DG Rooftop Solar PV systems are increasingly being integrated with advanced energy management systems. This allows users to monitor their energy consumption and adjust it in real-time to maximize savings and participate in demand response programs. There has been a growing interest in green financing options, such as green bonds and sustainability-linked loans, to fund rooftop solar projects. Investors and financial institutions are recognizing the long-term value and sustainability of these projects.

• According to the International Energy Agency (IEA), distributed rooftop solar installations surpassed 290 gigawatts globally in 2024, with over 38% contributed by DG (Distributed Generation) systems in residential and commercial sectors.

• According to the U.S. Department of Energy (DOE), the integration of smart inverters in rooftop PV systems increased by 52% between 2020 and 2024, enhancing grid stability and supporting decentralized energy generation in urban networks.

DRIVING FACTORS

Energy Independence to Augment Market Growth

Continuous reductions in the cost of solar panels, inverters, and other system components have made rooftop solar PV more affordable for residential, commercial, and industrial consumers. Falling costs have improved the return on investment (ROI) for solar installations. Various government incentives and policies at the federal, state, and local levels have played a crucial role in promoting rooftop solar adoption. These incentives may include tax credits, rebates, feed-in tariffs, and net metering programs. The desire for energy independence and reduced reliance on centralized power grids has driven many individuals and businesses to invest in rooftop solar PV systems. Generating one's electricity can provide greater control and stability over energy costs. Growing environmental awareness and concerns about climate change have prompted individuals and organizations to adopt renewable energy sources like solar power to reduce greenhouse gas emissions and mitigate their carbon footprint.

Technological Advancements to Propel Market Growth

Rooftop solar PV systems provide a source of electricity during power outages or grid disruptions, enhancing energy resilience. This became more significant during natural disasters and emergencies. Ongoing advancements in solar panel technology, including higher efficiency and durability, have improved the performance of rooftop solar systems, making them more attractive to consumers. Rooftop solar installations offer the potential for long-term electricity cost savings. As energy prices fluctuate, solar power can provide a stable and predictable source of electricity. Net metering policies allow solar PV system owners to receive credit for excess electricity they generate and feed into the grid. This financial incentive encourages adoption by reducing electricity bills.

• According to the Ministry of New and Renewable Energy (MNRE), India added 2.9 GW of rooftop solar capacity in FY 2023–24, marking a 41% rise due to supportive subsidy programs and net-metering reforms.

• According to the European Commission’s Renewable Energy Statistics, rooftop solar systems offset approximately 18 million tons of CO₂ annually, creating a strong regulatory push for decentralized solar adoption across industrial and residential buildings.

RESTRAINING FACTORS

Return on Investment (ROI) Uncertainty to Impede Market Expansion

The initial investment required for the purchase and installation of rooftop solar PV systems can be a significant barrier for many consumers and businesses, even with declining equipment costs. High upfront costs can deter potential adopters. The ROI for rooftop solar PV systems can vary depending on factors like local solar irradiance, energy prices, and the specific system's efficiency. This uncertainty can make potential buyers hesitant. Technical and administrative challenges related to grid interconnection and utility requirements can add complexity and cost to the installation process. In some cases, utilities may impose fees or restrictions on DG systems. Lengthy and complex permitting processes, as well as regulatory barriers, can slow down rooftop solar installations and increase costs. These barriers can vary by region and can discourage potential adopters.

• According to the National Renewable Energy Laboratory (NREL), installation costs for rooftop PV systems remain 25–30% higher than ground-mounted setups due to complex mounting structures and wiring layouts.

• According to a Solar Energy Industries Association (SEIA) technical report, nearly 22% of potential rooftop projects are delayed because of grid interconnection constraints and voltage regulation issues, particularly in high-density urban zones.
