What percentage of electricity demand is covered by solar PV?

In 2019, solar PV supplied 9% of electricity demand in Germany and 19% in California (Figure 5). Existing plans contemplate penetration higher than 20% in several power systems by 2030. Figure 5. Percentage of electricity demand covered by solar PV in different markets worldwide

What are the benefits of solar PV?

The perception of solar PV as a mature technology and auctions, which have become the preferred method for governments to select new solar capacity worldwide, 38 decrease the risk and the financial costs, which in turn reduces the cost of solar electricity. 36 Improvements in maintenance and lifetime will also lower the cost.

Is solar photovoltaics ready for the future?

Solar photovoltaics (PV) is a mature technology ready to contribute to this challenge. Throughout the last decade, a higher capacity of solar PV was installed globally than any other power-generation technology and cumulative capacity at the end of 2019 accounted for more than 600 GW.

What factors affect the competitiveness of solar energy?

The available power grid infrastructure was built to work with consistent power generation levels and these grids may not be able to cope with the inconsistency of solar energy. Another factor that reduces the competitiveness of solar energy is how often electricity is produced; also known as its capacity factor.

How much electricity does solar PV supply?

In 2010, no large power system existed in which solar PV supplied more than 3% of the annual demand. In 2019, solar PV supplied 9% of electricity demand in Germany and 19% in California (Figure 5). Existing plans contemplate penetration higher than 20% in several power systems by 2030. Figure 5.

Why do we need a solar PV policy?

Adequate policies are needed to ensure that high installation rates are maintained in the short term and that the potential environmental, social, and economic benefits of solar PV are effectively materialized.
