National Solar Photovoltaic Power Generation Advantages

Photovoltaics (PV) and concentrating solar power are likely to continue to grow rapidly—the National Renewable Energy Laboratory (NREL) projects solar energy could provide 45% of the electricity in the United States by 2050 if the energy system is fully decarbonized—and technology costs are projected to continue to decline.

New solar technologies are capturing more and more of the sun’s rays. The National Renewable Energy Laboratory has created six-junction solar cells that convert 47% of the captured sunlight into electricity—by comparison, most commercially available modules convert less than 20%. Silicon solar cells can withstand the test of time.

Solar energy can be harnessed in two primary ways. First, photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight. Second, solar thermal technologies utilize sunlight to heat water for domestic uses, warm building spaces, or heat fluids to drive electricity-generating turbines.

As of the end of 2018, the global capacity of installed and grid-connected solar PV power reached 480 GW (Figure 6), representing 20% year-on-year growth compared to 2017 (386 GW) and a compound annual growth rate (CAGR) of nearly 43% since 2000 (IRENA, 2019c).

Benefits of solar photovoltaic energy generation outweigh the costs, according to new research from the MIT Energy Initiative. Over a seven-year period, decline in PV costs outpaced decline in value; by 2017, market, health, and climate benefits outweighed the cost of PV systems.

6 FAQs about [National Solar Photovoltaic Power Generation Advantages]

Do solar photovoltaic energy benefits outweigh the costs?

This article appears in the Spring 2020 issue of Energy Futures, the magazine of the MIT Energy Initiative. Benefits of solar photovoltaic energy generation outweigh the costs, according to new research from the MIT Energy Initiative.

How efficient is a solar PV system?

Experimental PV cells and PV cells for niche markets, such as space satellites, have achieved nearly 50% efficiency. When the sun is shining, PV systems can generate electricity to directly power devices such as water pumps or supply electric power grids.

How will solar PV transform the global electricity sector?

Alongside wind energy, solar PV would lead the way in the transformation of the global electricity sector. Cumulative installed capacity of solar PV would rise to 8 519 GW by 2050 becoming the second prominent source (after wind) by 2050.

Is solar PV a competitive source of new power generation capacity?

Solar PV is emerging as one of the most competitive sources of new power generation capacity after a decade of dramatic cost declines. A decline of 74% in total installed costs was observed between 2010 and 2018 (Figure 10).

How can the solar PV industry continue to grow?

The further growth of the solar PV industry largely depends on reducing the balance of system (BoS), which makes up most of the total installed system costs and has the greatest potential for cost reduction.

Is solar PV a strategic renewable technology?

This report clearly points out that solar PV is one of the strategic renewable technologies needed to realise the global energy transformation in line with the Paris climate goals. The technology is available now, could be deployed quickly at a large scale and is cost-competitive.
