Solar energy is the term used to describe the heat and light emitted by the sun that can be captured and transformed into useful types of energy. It is a form of renewable energy that utilises the sun's immense power as a sustainable and clean source of electricity and heat.

The process of capturing solar energy involves the use of solar panels, also known as photovoltaic (PV) panels. Photovoltaic cells present in the PV panels are made of semiconductor material, which absorbs some photons from sunlight while others are reflected off the cell. These absorbed are then used to generate electric current through the photovoltaic effect. As the demand for photovoltaic installations rises, storage grid adoption is anticipated to soar, fuelling solar energy market demand along with the need for lithium-ion batteries for solar energy storage.

Growing Energy Demand

The growing energy demand coupled with the increasing population around the world has been a major factor propelling the global solar energy market growth. Governments and energy companies are increasingly focusing on more sustainable energy generation alternatives, owing to the constant depletion of fossil fuels.

Transition towards renewable energy sources

The global transition towards renewable energy sources is fostering a more decentralised energy landscape. Solar energy, particularly distributed generation, empowers consumers to become prosumers, generating their electricity and potentially feeding excess energy back into the grid.

Government regulations and policies

Governments around the world are also implementing strict regulations to reduce carbon emissions and promote solar energy adoption. These policies include feed-in tariffs, tax credits, grants, and renewable portfolio standards.

Rising focus on environmental issues

One of the major solar energy market trends enhancing the value of the market includes the growing concerns about the exploitation of fossil fuels. The rising focus on environmental issues has increased awareness about solar energy as a clean and sustainable energy alternative.

Rising environmental concerns caused on by the release of harmful greenhouse gases that cause air pollution are predicted to increase demand for solar energy, a clean and sustainable energy source. For instance, converting from fossil fuels to solar power could result in a large reduction in carbon dioxide emissions, which raise global temperatures and promote climate change. IRising temperatures cause more extreme weather conditions, such as increasing sea levels, glacier melt, and altered ecosystems. Using solar energy reduces greenhouse gas emissions and the need for fossil fuels, which in turn reduces the carbon footprint.

The continuous decrease in the cost of solar panels and associated equipment has emerged as a major solar energy market driver. Improvements in manufacturing efficiency, economies of scale, and technological advancements have helped to significantly lower the cost of solar systems. As a result, solar energy is now more widely available and economically viable for a range of uses, such as utility-scale use and residential and commercial applications.

Utility sector is a leading segment due to the growing development of utility-scale solar facilities

The utility sector is likely to be a significant segment of the market. The primary factors contributing to the segment's growth are the increasing construction of utility-scale solar plants and the greater operational effectiveness of photovoltaic (PV) panels in comparison to other options.

Photovoltaic power plants of considerable scale, comprised of multiple PV arrays, serve as an advantageous asset for utilities. These plants can be built relatively quickly compared to traditional power plants, thanks to streamlined installation processes and simplified electrical connectivity. This efficiency in construction allows utilities to expedite the deployment of solar energy, meeting energy demands more rapidly while leveraging the flexibility and speed inherent in photovoltaic technologies.

According to our solar energy market analysis, it is anticipated that solar energy generation will be increasingly adopted in residential applications owing to the rising demand for energy in homes and the evolving perspective of people about sustainable living. Its scalability allows homeowners to generate electricity for their use and reduce the reliance on conventional grids while addressing the escalating energy demands of modern households.

Solar photovoltaics are growing in popularity due to its low cost and technological advancements

Solar PV systems use semiconductor-based solar panels, usually silicon, to directly convert sunlight into electricity. Direct current (DC) power is produced when sunshine strikes the solar cells, exciting electrons. In houses, companies, and the electrical grid, this direct current (DC) electricity is transformed into alternating current (AC) using an inverter.

The International Renewable Energy Agency reported that between 2022 and 2021, the installed capacity of solar photovoltaics worldwide climbed by more than 22%, while concentrated solar power systems had a 2% growth in installed capacity. This indicates that solar photovoltaics have been more widely used than concentrated solar power systems. Solar photovoltaics (PV) is anticipated to play a major role in helping Australia meet its 2030 objective of producing 82% of its electricity from renewable sources, such as wind and solar PV, increasing the solar energy market share.
