Solar solutions
Key to decarbonising energy generation.
- Decarbonising the energy sector is essential to achieving a goal of reducing emissions to net zero
- Solar power, a key climate theme in the HSBC Climate Solutions Database (HCSD), power could play a key role in achieving that
- Falling costs and supportive policies could spur further investment along the supply chain and be supportive for solar power generation
The energy generation sector is the largest contributor to global greenhouse gas (GHG) emissions, being responsible for 40% of global CO2 emissions in 2022. So decarbonising the sector is essential if the world is to achieve its goal of reducing emissions to net zero.
Renewables accounted for around 28% of global power generation in 2021, according to the International Energy Agency (IEA). But much more is needed, and solar power could play a key role. Indeed, the IEA estimates that to meet its net-zero scenario, solar power generation would have to increase more than seven times by 2030, compared to 2021 levels.

Increase in solar power generation needed by 2030 in the IEA's net-zero scenario
Falling costs and favourable government policies could help boost investment in solar over the coming years, in our view.
Falling costs…
The cost of solar power plant has consistently fallen over the past few years, mainly due to increases in the supply of photovoltaic (PV) solar equipment and innovations in manufacturing. In the five years to 2020, the global solar system cost has more than halved, according to Bloomberg New Energy Finance (BNEF) estimates. And there could be more to come: BNEF says global solar system costs are expected to fall further by c.43% by 2030 and c.63% by 2050 (both compared to 2020), making solar power generation significantly cheaper than fossil-fuels based power generation.
…and supportive policies…
The policy environment is also evolving quickly. PV Solar cells are the most commonly used solar power plant technology across the world, and the global supply chain is concentrated in China. The country accounts for c.79% of global polysilicon, c.97% of wafers, c.85% of cells, and 75% of modules as of 2021, as per the IEA.
the solar photovoltaic global supply chain is concentrated in China.
Other jurisdictions, however, are trying to incentivise domestic solar equipment manufacturers. Making solar equipment manufacturing more competitive outside China would likely require substantial policy support. Last year, the US introduced the Inflation Reduction Act (IRA), which aims to create incentives for renewable power producers, including solar producers. The European Union’s RePowerEU Plan includes measures on renewable energy and energy efficiency. And the Australian Renewable Energy Agency (ARENA) has announced AUD14m in funding for a private utility scale solar array manufacturer.
…could spur further investment along the supply chain
A broad range of companies are involved in the solar sector, including those which offer products and services in the following areas:
- Power Generation – companies that generate and sell electricity from solar power plants
- PV Solar Cells – companies that manufacture and sell solar cells, panels or modules traditionally used to generate solar power from building rooftops or solar parks
- Solar Thermal – companies that offer solutions for solar thermal power plants which use sunlight to heat fluids to high temperatures, which drives traditional steam turbines or engines to generate electricity
- Concentrating solar panels (CSP) – companies that offer mirrors or lenses which concentrate sunlight (solar energy) to create high temperatures to convert water into steam
- Wafer – companies that manufacture and/or sell solar wafers
- Other – companies that manufacture other products which form part of the solar value chain such as solar inverters, raw materials for solar cells, solar cell manufacturing equipment, precision equipment, adhesives, ingots, testing equipment, and solar glass
