Distributed Solar Power Generation Market Size and Trends

The global distributed solar power generation market size was valued at USD 109.92 billion in 2023. It is anticipated to reach from USD 116.31 billion in 2024 to USD 182.73 billion by 2032, registering a CAGR of 5.81% during the forecast period (2024-2032). The increase in distributed solar power generation market share during the forecast period is related to the cost-effectiveness of amorphous silicon and government initiatives to promote roof-top solar panels.

Distributed solar power is generated through a decentralized solar photovoltaic module and is extensively used in the residential and commercial sectors. Continuously rising temperatures, growing need for energy conservation and reducing CO2 emission, declining dependency on fossil fuel, decreasing prices of solar PV modules, and increasing demand for clean energy sources drive the market growth. Thus, the megatrends above for energy transformation will drive market growth in the upcoming years.

Solar power is the second-largest contributor to renewable energy production. The installation of distributed solar panels reduces the load on grid generation and transmission, and it facilitates cheaper energy generation. As per the International Renewable Energy Agency (IREA), the cumulative installed capacity of solar PV modules across the globe is projected to reach 8,519 GW by 2050. Consumers generally favor grid power over off-grid power due to its inexpensive initial investment and lack of space requirement for electricity generation. This is anticipated to impede the expansion of the distributed power generation market throughout the projected timeframe. However, the increasing environmental worries, global requirements to reduce carbon emissions, and favorable policies implemented by various governments to promote renewable energy sources create a favorable situation for the distribution power generating business.

Distributed Solar Power Generation Market Growth Factors

Cost-Effectiveness of Amorphous Silicon

The cost-effectiveness of amorphous silicon (A-Si PV) is expected to significantly enhance its adoption in the distributed solar power generation market. Amorphous silicon holds the largest market share due to its ease of production and attractiveness to customers reluctant to invest in solar panels. It is more cost-effective than other solar cell varieties, such as mono-crystalline silicon, with higher production costs. The affordability of amorphous silicon makes it an appealing choice for businesses and consumers aiming to reduce their carbon footprint and energy expenses. Additionally, its excellent resistance to shading and versatile applications further increase its appeal.

Additionally, the demand for amorphous silicon is anticipated to grow in line with the rising demand for renewable energy. Its cost-effectiveness, adaptability, and lightweight construction position it as a market leader in solar energy. Market expansion is expected to be driven by ongoing research and development, technological advancements, favorable government policies, and increasing environmental concerns.

• For instance, according to ResearchGate, amorphous silicon films produced through the Inductively Coupled Plasma (ICP) deposition technique achieve a conversion efficiency of 9.6%.

Government Initiatives to Promote Roof-Top Solar Panels

The rooftop segment is projected to witness the fastest growth due to increasing demand for power generation in the residential sector. Government initiatives worldwide are promoting rooftop solar power generation. For example, India's Ministry of New & Renewable Energy has planned to scale up grid-connected solar power projects from 20,000 MW to 100,000 MW by 2022.

In addition, the power industry has experienced a significant shift in power generation methods in recent years. Rising global temperatures and depleting fossil fuels have compelled customers to adopt alternative energy sources, further driving market growth. The ground-mounted segment dominates the distributed solar power generation market due to its rising demand in the commercial and utility sectors.

Distributed Solar Power Generation Market Restraining Factors

High Initial Setup Cost

The distributed solar power generation market faces challenges due to high initial setup costs. Off-grid systems requiring storage systems are costly to construct, hindering market expansion. Although solar photovoltaic module prices are decreasing and government programs encourage domestic solar power consumption, high initial costs remain a significant barrier. Amorphous silicon photovoltaics (A-Si PV) have the largest market share due to their ease of manufacture and increased customer adoption, avoiding significant financial investments. However, their low efficiency, short warranties, and limited lifespans may hinder their utilization. The mono-Si category is expected to increase due to its efficiency and durability.

Meanwhile, though highly profitable, the Concentrated Photovoltaics (CVP) segment faces higher installation costs due to the required cooling systems, slowing its expansion. The rooftop category is anticipated to experience rapid growth due to demand from residential and business customers. For example, installing a solar power plant in Karnataka costs between USD 480 to USD 720 per kW.

Distributed Solar Power Generation Market Opportunities

Expanding into Remote Areas

Geographical expansion into remote regions presents a substantial opportunity for the distributed solar power generation market. With the rise of remote work, more individuals are relocating to rural areas for recreational opportunities, familial connections, and family-friendly communities. This trend offers rural community leaders new opportunities to attract and retain remote workers by promoting the benefits of living and working in their localities.
Rural communities can capitalize on this opportunity by developing co-working spaces, promoting alternative workstations, and improving transportation infrastructure, including airports and public transportation.

Additionally, providing high-speed internet access is crucial for remote workers to conduct business efficiently. By offering the necessary support and infrastructure, rural communities can become desirable locations for remote workers, contributing to expanding the distributed solar power generation industry.
