How much solar energy will be generated in 2030?

Reaching an annual solar PV generation level of approximately 8 300 TWh in 2030, in alignment with the Net Zero Scenario, up from the current 1 300 TWh, will require annual average generation growth of around 26% during 2023-2030.

What is the contribution of solar energy to global electricity production?

While the contribution of solar energy to global electricity production remains generally low at 3.6%, it has firmly established itself among other renewable energy technologies, comprising nearly 31% of the total installed renewable energy capacity in 2022 (IRENA, 2023).

Does a solar PV system generate more electricity a year?

A solar PV system on the south coast of England for example will generate more electricity annual than one of a similar size, orientation and inclination in the north of Scotland. A solar PV system on the south coast of England for example will generate more electricity annually.

How will solar PV & wind impact global electricity generation?

The share of solar PV and wind in global electricity generation is forecast to double to 25% in 2028 in our main case. This rapid expansion in the next five years will have implications for power systems worldwide.

Does solar generation vary from year to year?

From year to year there is variation in the generation for any particular month. There is less variation in the annual generation from year to year as weather patterns over the year average out. The annual generation of a solar PV system also varies with location in the country.

Which countries have the most solar PV installed capacity in 2022?

In 2022, the most significant expansion in the solar PV market occurred in China, the US, and India, with increments of 86.1 GW, 17.8 GW, and 13.5 GW, respectively (IRENA, 2023). Fig. 2 shows the contribution of each continent in the world's solar PV installed capacity in 2018, followed by 2030 and 2050 based on IRENA’s REmap analysis.
