4 Frequently Asked Questions about "Forecast of future solar power generation costs"

Is there a future for solar energy?

The future, it seems, arrived decades early. Despite various attempts in the past to point out the risk of underestimating renewable energy technologies and, in particular, solar PV, such as by Victoria et al., Jaxa-Rozen and Trutnevyte, and Xiao et al., this issue persists across energy scenarios. This cost overestimation matters.

Are solar photovoltaics cost projections overestimating actual costs?

Cost projections for solar photovoltaics, wind power, and batteries are over-estimating actual costs globally ”, published in Applied Energy, systematically reviewed 40 studies and 150 long-term scenarios for renewable energy technologies.

Do projections overestimate the costs of wind power and solar photovoltaics?

Projections overestimate the costs of wind power and solar photovoltaics (PV) by excluding existing flexibility strategies like dispatchable renewables, demand response, and grid expansion, and by adding inflated integration costs due to low spatial and temporal granularity .

Will solar PV capacity exceed forecasts by 2030?

Cumulative solar PV capacity is expected to exceed most energy analysts' forecasts by 2030. If the solar market trajectory continues as projected, total global solar installations are set to triple over the next five years, surpassing 6 TW by 2029 in the Medium Scenario.
