In this chapter, we will understand Global and Indian Solar Market. As we know, today solar energy is not only an alternate source of electricity, instead it is becoming one of the main sources of global power sector. Every country is investing in developing solar power plants because they provide clean, renewable, affordable, and abundant electricity.
Twenty+ years ago, solar energy was considered an expensive source of electricity and used in special applications only such as space and remote areas. But today it has become the most economical source of power and being widely used from homes to schools, hospitals, railways, and large industrial applications.
India is also becoming one of the top growing countries in the world’s solar market. Due to several reasons such as abundant solar radiation, increasing electricity demand, declining solar equipment costs, and supportive government policies, solar energy is becoming India’s important electricity source for upcoming decades.
What is the Solar Market?
Solar Market can be defined as an ecosystem that involves generation of electricity from sunlight.
It includes components such as technologies, professionals, manufacturers, service providers, investors, government bodies, and consumers associated with solar energy.
Components of Solar Market
The solar market is much bigger, it comprises various components/sectors which are interlinked, and some of then are listed below –
| Component/Sector |
Example |
| Manufacturing | Solar panels, solar cells, solar inverters, MMS structures, solar cables |

These sectors combinedly are creating millions of jobs worldwide.
Why is the World Shifting Towards Solar Energy?
The following are some major factors driving the global transition towards the solar energy –
Unlimited Source of Energy
The Sun produces large amounts of energy every day, and it gets naturally replenished and will continue to be available for billions of years.
This key benefit makes solar energy one of the most sustainable energy resources available to humanity.
Increasing Electricity Demand
As electricity demand is growing every year, and the following are some possible reasons behind this –
- Population growth
- Urbanization
- Industrial expansion
- Inception of Electric vehicles, data centers, air conditioning, & digital infrastructure
With fossil fuels, it is very difficult to meet this growing demand of electricity, due to increased environmental impacts, fuel costs, and limited availability.
Reducing Cost of Solar Technology
Market research shows that another key reason behind solar energy’s growing adoption is due to significant drop in solar equipment costs over last twenty+ years.
As a result of this, many solar projects can generate electricity at competitive prices over their operating life span.
Environmental Benefits
Conventional power plants produce greenhouse gases and other environmental pollutants.
But solar power plants generate electricity without causing any direct environmental impact.
This feature of solar energy supports global efforts to reduce climate change.
Energy Security
Many countries are dependent on imported fossil fuels.
But solar energy allows those countries to produce electricity domestically. This helps them improve their energy independence and reduce exposure to fuel price fluctuations.
Government Support
Governments worldwide also promoting solar adoption through following –
- Renewable energy policies
- Competitive bidding
- Rooftop solar programs
- Manufacturing incentives
- Research funding
- Grid modernization
- Energy storage initiatives
All these policies have increased solar deployment across residential, commercial, industrial, and utility-scale sectors.
Evolution of the Global Solar Industry
The global solar industry has evolved through many stages as discussed below –
Stage 1: Scientific Discovery
Scientists discovered that using certain semiconductor materials we can convert sunlight into electricity. This phenomenon today is known as the photovoltaic effect.
Stage 2: Space Applications
Initially, the commercial use of solar cells was in special applications only like satellites.
Stage 3: Limited Commercial Use
With improved manufacturing, solar systems were developed for supplying electricity to remote villages, communication towers, and off-grid locations.
Stage 4: Mass Production
Mass-scale manufacturing reduced costs and increased efficiency.
At this stage, solar panels became practical for residential, commercial, and industrial applications.
Stage 5: Utility-Scale Solar Farms
Most countries started installing their own solar power plants of capacity ranging from 1 MW to several GWs. These solar parks now supply electricity directly to national grids.
Stage 6: Smart Solar Era
The future of solar is not limited to generating electricity. But modern solar systems are integrating the followings –
- Battery Energy Storage Systems (BESS)
- Artificial Intelligence (AI)
- Smart inverters
- Digital monitoring
- Predictive maintenance
- Smart grids
- Electric vehicle charging infrastructure
