This is mandated in several Chinese provinces and written into auctions in many other countries.</p>\n\n\n\n<p>In the US, the solar industry is expected to nearly triple in size between 2023 and 2028, adding 236 GWdc to an installed base of 142 GWdc (as of year-end 2022). </p>\n\n\n\n<p>These projections suggest that solar energy could account for as much as 20% of the total electricity generation. The demand for solar power in the European Union rose by 37%, which could be related to the approaching final of the 2020 EU targets for renewable energy.</p>\n\n\n\n<p>However, the market faces supply chain disruptions, rising costs, and project delays. Despite these challenges, the industry is expected to experience robust growth due to soaring demand and attractive long-term incentives. </p>\n\n\n\n<h2>Solar panel efficiency and sustainability</h2>\n\n\n\n<p>Solar panel efficiency is the percentage of incoming sunlight that a single solar panel can convert into electricity. The most efficient solar panels available today are 22.8% efficient, while the most efficient solar cells developed by scientists offer 39.5% efficiency. </p>\n\n\n\n<p>“Solar energy is the most abundant energy resource on Earth,” according to the National Renewable Energy Laboratory. Solar energy is a clean and sustainable energy source that creates no harmful greenhouse gas emissions, making it an environmentally friendly alternative to fossil fuels. </p>\n\n\n\n<p>The average efficiency of solar panels is between 15% and 20%, with outliers on either side of the range. Higher-efficiency panels are more expensive but can help meet energy needs, especially in limited roof space or shading cases. </p>\n\n\n\n<p>The demand for solar energy is increasing worldwide. According to Statista, the global demand for solar photovoltaic (PV) will reach 1,000 GW by 2023. The International Energy Agency (IEA) projects that solar PV will become the largest source of electricity generation by 2035, with a capacity of 16% of global electricity generation. Solar PV will account for 4.5% of global electricity generation by 2050. </p>\n\n\n\n<p>As solar energy infrastructure expands, more efficient solar panels will be developed, leading to further growth in solar energy production.</p>\n\n\n\n<h3>Solar panel efficiency</h3>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Solar Panel Brand</th><th>Panel Model</th><th>Efficiency (%)</th></tr></thead><tbody><tr><td>SunPower</td><td>M Series</td><td>22.8</td></tr><tr><td>Canadian Solar</td><td>HiHero</td><td>22.8</td></tr><tr><td>REC</td><td>Alpha Pure </td><td>22.7</td></tr><tr><td>Panasonic</td><td>EverVolt</td><td>22.5</td></tr></tbody></table></figure>\n\n\n\n<p>While solar energy is a clean and sustainable energy source, there are concerns about the sustainability of solar panels. Solar panels contain small amounts of valuable materials, such as silver, but they are mostly made of glass, a highly low-value material. The long lifespan of solar panels also disincentives innovation in recycling and end-of-life management. </p>\n\n\n\n<p>However, solar energy is still a more sustainable and environmentally friendly alternative to fossil fuels. To stay on a pathway limiting global warming to 1.5°C, annual renewable power capacity additions must grow three times the current level by 2030. <a href=https://www.greenmatch.co.uk/"https://www.irena.org/Digital-Report/World-Energy-Transitions-Outlook-2023/">IRENA’s World Energy Transitions Outlook</a> shows that tripling renewable power capacity until 2030 and beyond will get us back on track. </p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"689\" height=\"423\" src=https://www.greenmatch.co.uk/"https://cdn.greenmatch.co.uk/cdn-cgi/image/format=auto/2/2023/11/Global-solar-photovoltaic-capacity-by-region-2022_-1.png/" alt=\"\" class=\"wp-image-93648\" srcset=\"https://cdn.greenmatch.co.uk/cdn-cgi/image/format=auto/2/2023/11/Global-solar-photovoltaic-capacity-by-region-2022_-1.png 689w, https://cdn.greenmatch.co.uk/cdn-cgi/image/format=auto/2/2023/11/Global-solar-photovoltaic-capacity-by-region-2022_-1-300x184.png 300w\" sizes=\"(max-width: 689px) 100vw, 689px\" /></figure>\n\n\n\n<h2>Future trends in solar PV</h2>\n\n\n\n<p>Solar energy is expected to play a significant role in the future of energy production, with the most efficient solar panels available on the market having an efficiency rate of 22.8%. The latest developments and breakthroughs in solar technology include longer-lasting solar cells, solar cells that you can print onto flexible surfaces, solar panels that track the sun from east to west throughout the day, and solar power plants that work at night. </p>\n\n\n\n<p>To catch up with this, more than sixty countries need to generate more than 15% of their electricity from solar. This could provide 45% of the electricity by 2050 if the energy system is fully decarbonised. Globally, this would imply a 68% increase in average annual solar PV investment from now until 2050 (to USD 192 billion/yr). Solar PV investment stood at USD 114 billion/yr in 2018. </p>\n\n\n\n<p>Today, solar PV penetration of electricity production per country has seen a significant rate of 10% in 2022 from nine countries. Spain topped the list with 19%, followed by Greece (17.5%), Chile (17%), and the Netherlands (15.9%). This means that PV contribution amounted to 6.2% of the electricity demand in the world in total, while the penetration rates of the EU and China were only 8.7% and 6.5%, respectively. </p>\n\n\n\n<p>Table: Projected Global Trends in Solar PV (2023-2033)</p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Year</th><th>Projected Solar PV Capacity (GW)</th><th>Projected Solar PV Installations (GW)</th><th>Projected Solar PV Penetration (%)</th><th>Projected Investment in Solar PV (£ billion)</th></tr></thead><tbody><tr><td>2023</td><td>1,185</td><td>240</td><td>6.2</td><td>96.3</td></tr><tr><td>2028</td><td>2,012.5</td><td>270</td><td>10.6</td><td>129.2</td></tr><tr><td>2033</td><td>2,840</td><td>300</td><td>15.0</td><td>162.1</td></tr></tbody></table></figure>\n\n\n\n<p>Integrating solar PV with renewable energy sources, such as wind and hydro, will also become more prevalent. This hybrid approach allows for a more reliable and consistent energy supply, minimising the impact of intermittency.</p>\n\n\n\n<p>Furthermore, the increasing adoption of innovative grid technologies will enable better integration of solar PV into the existing energy infrastructure. These technologies allow for real-time monitoring and control of energy flows, optimising the use of solar electricity and improving overall grid stability.</p>\n\n\n\n<p>Solar PV is poised to play a significant role in shaping a more sustainable future, reducing greenhouse gas emissions, and mitigating the effects of climate change.</p>\n</div></div>\n","lastUpdated":"16 November

Global Solar Energy Trends in 2024: Facts and Forecasts

Solar panels are the most popular solar energy collection method.

As the global shift towards renewable energy continues, the solar photovoltaic (PV) industry is experiencing unprecedented growth. With impressive statistics to back it up, the solar PV industry has solidified its position as a critical player in the transition to clean and sustainable energy sources.

This is evident in the evolution of solar panel efficiency over time. In the 1960s, Hoffman Electric achieved 14% photovoltaic (PV) cell efficiency. By 2015, companies like SolarCity and Panasonic announced efficiencies of over 22%. As of 2023, most commercial panels have 17% to 20% efficiencies, but researchers have developed PV cells with efficiencies approaching 50%.

Solar technologies are becoming more efficient every year, and this trend is expected to continue as research and development in this field progresses. Solar energy is expected to be an infinite source of energy that creates no harmful greenhouse gas emissions, making it an environmentally friendly alternative to fossil fuels.

The growth of solar energy is expected to continue, with some projections estimating that global solar installations could reach 4.7 terawatts by 2050.

Global solar photovoltaic statistics and facts

The statistics surrounding the solar PV industry are awe-inspiring. Solar PV installations have also substantially reduced greenhouse gas emissions. According to the International Energy Agency, solar PV systems installed in 2020 alone helped to avoid approximately 2.6 billion tonnes of carbon dioxide emissions. This is equivalent to taking over 560 million cars off the road for a year.

The global cumulative installed solar PV capacity surge is a testament to the world’s growing commitment to renewable energy. According to Statista, as of 2022, the global cumulative solar PV capacity amounted to 1,177 gigawatts, with approximately 239 gigawatts of new PV capacity installed that same year.

This is a substantial increase from 2003 when the global cumulative installed solar PV capacity was less than 2.6 gigawatts.

Solar PV technology has seen significant growth and development over the years, and it is expected to continue growing in the future due to its numerous advantages, including its abundance, renewability, and cleanliness.

Here is the overview of the statistics of the solar industry according to IEA and Statista

The global photovoltaic (PV) solar capacity is expected to reach 1.3 terawatts (TW) by 2023

Global solar photovoltaic capacity has grown from around five gigawatts in 2005 to approximately 940 gigawatts in 2021

Solar energy is the most abundant energy resource on earth

Solar panels are made of large amounts of aluminium, copper, and glass, and 90%–97% of solar panel materials can be recycled and reused for other purposes when they break down

Solar energy users save about 35 tons of CO2 emissions and 75 million barrels of oil yearly

Utility-scale PV power plants accounted for 70% of total solar electricity generation in 2022.

Expected global growth rate of 27% between 2021 and 2031

90%–97% of solar panel materials can be recycled and reused for other purposes when they break down

Most panels today are between 15% and 20% efficient. Meaning they can convert the same amount of energy.

China produces the most solar power in the world, at 306.9 gigawatts, followed by the United States (95.9), Japan (74.2), Germany (58.5), and India (49.7).

Solar panels are the most popular method of collecting solar energy, and US solar power generation reached 145.6 terawatt hours in 2022.

The smart solar power market is projected to reach approximately £36.25 billion by 2031, growing at a CAGR of 13.6%.

In the UK, more than 17,000 households installed solar panels every month in 2023.

According to recent data, the solar PV market is projected to grow at a compound annual growth rate of over 20% between 2021 and 2026.

One of the key drivers of this growth is the declining prices of solar panels. However, this may not be the case in most countries, as the United Kingdom (UK) has witnessed a surprising price rise in solar panels.

This hit started after Corona 2021 and rose on average from £1,370 to £2,061.

Here is an overview of the price increase over the last two years in the UK:

System size	System price 2021	System price 2023	Price increase %	Projected installations 2023
4 kW	£6.471	£10,420	61%	141.180
10 kW	£14.810	£22,610	53%	59.088
10-50 kW	£50.550	£65,850	30%	5.304

As technology improves and economies of scale are realised, the cost of producing solar panels will significantly decrease. This will make solar PV installations more affordable and accessible to a broader range of consumers. Additionally, advancements in solar PV technology, such as developing more efficient solar cells and improved energy storage solutions, have increased solar PV systems’ overall efficiency and reliability.

In 2022, the global cumulative solar photovoltaic (PV) capacity amounted to 1,177 gigawatts (GW), with approximately 239 GW of new PV capacity installed in the same year, with a 24% growth of new installations.

According to the International Energy Agency (IEA), renewable capacity will meet 35% of global power generation by 2025. The IEA foresees solar PV to reach 4.7 terawatts (4,674 GW) by 2050 in its high-renewable scenario, of which more than half will be deployed in China and India, making solar power the world’s largest source of electricity. This growth is expected to continue, with the International Energy Agency projecting that solar PV will account for 4.5% of total global electricity generation.

Comparison between the number of installed solar PV in 2021 and 2022 represents a significant increase in solar energy capacity, demonstrating the rapid growth of this renewable energy source.

Solar Power Growth and Capacity

Year	Global Cumulative Solar PV Capacity (GW)	New PV Capacity Installed (GW)	Solar Power Growth (%)
2021	938	239	25.23

Solar panel efficiency and sustainability

Solar panel efficiency is the percentage of incoming sunlight that a single solar panel can convert into electricity. The most efficient solar panels available today are 22.8% efficient, while the most efficient solar cells developed by scientists offer 39.5% efficiency.

“Solar energy is the most abundant energy resource on Earth,” according to the National Renewable Energy Laboratory. Solar energy is a clean and sustainable energy source that creates no harmful greenhouse gas emissions, making it an environmentally friendly alternative to fossil fuels.

The average efficiency of solar panels is between 15% and 20%, with outliers on either side of the range. Higher-efficiency panels are more expensive but can help meet energy needs, especially in limited roof space or shading cases.

The demand for solar energy is increasing worldwide. According to Statista, the global demand for solar photovoltaic (PV) will reach 1,000 GW by 2023. The International Energy Agency (IEA) projects that solar PV will become the largest source of electricity generation by 2035, with a capacity of 16% of global electricity generation. Solar PV will account for 4.5% of global electricity generation by 2050.

As solar energy infrastructure expands, more efficient solar panels will be developed, leading to further growth in solar energy production.

Solar panel efficiency

Solar Panel Brand	Panel Model	Efficiency (%)
SunPower	M Series	22.8
Canadian Solar	HiHero	22.8
REC	Alpha Pure	22.7
Panasonic	EverVolt	22.5

While solar energy is a clean and sustainable energy source, there are concerns about the sustainability of solar panels. Solar panels contain small amounts of valuable materials, such as silver, but they are mostly made of glass, a highly low-value material. The long lifespan of solar panels also disincentives innovation in recycling and end-of-life management.

However, solar energy is still a more sustainable and environmentally friendly alternative to fossil fuels. To stay on a pathway limiting global warming to 1.5°C, annual renewable power capacity additions must grow three times the current level by 2030. IRENA’s World Energy Transitions Outlook shows that tripling renewable power capacity until 2030 and beyond will get us back on track.

Future trends in solar PV

Solar energy is expected to play a significant role in the future of energy production, with the most efficient solar panels available on the market having an efficiency rate of 22.8%. The latest developments and breakthroughs in solar technology include longer-lasting solar cells, solar cells that you can print onto flexible surfaces, solar panels that track the sun from east to west throughout the day, and solar power plants that work at night.

To catch up with this, more than sixty countries need to generate more than 15% of their electricity from solar. This could provide 45% of the electricity by 2050 if the energy system is fully decarbonised. Globally, this would imply a 68% increase in average annual solar PV investment from now until 2050 (to USD 192 billion/yr). Solar PV investment stood at USD 114 billion/yr in 2018.

Today, solar PV penetration of electricity production per country has seen a significant rate of 10% in 2022 from nine countries. Spain topped the list with 19%, followed by Greece (17.5%), Chile (17%), and the Netherlands (15.9%). This means that PV contribution amounted to 6.2% of the electricity demand in the world in total, while the penetration rates of the EU and China were only 8.7% and 6.5%, respectively.

Table: Projected Global Trends in Solar PV (2023-2033)

Year	Projected Solar PV Capacity (GW)	Projected Solar PV Installations (GW)	Projected Solar PV Penetration (%)	Projected Investment in Solar PV (£ billion)
2023	1,185	240	6.2	96.3
2028	2,012.5	270	10.6	129.2
2033	2,840	300	15.0	162.1

Integrating solar PV with renewable energy sources, such as wind and hydro, will also become more prevalent. This hybrid approach allows for a more reliable and consistent energy supply, minimising the impact of intermittency.

Furthermore, the increasing adoption of innovative grid technologies will enable better integration of solar PV into the existing energy infrastructure. These technologies allow for real-time monitoring and control of energy flows, optimising the use of solar electricity and improving overall grid stability.

Solar PV is poised to play a significant role in shaping a more sustainable future, reducing greenhouse gas emissions, and mitigating the effects of climate change.
