Solar

Photovoltaics at global scale.

Utility solar, distributed PV, cell technology, manufacturing, costs and grid integration.

Solar is now the fastest-growing source of electricity in the world. This hub covers utility-scale solar farms, rooftop systems, module manufacturing, trade policy and the falling costs that have made solar the cheapest new power in many regions.

Rapid growth brings new problems: midday price collapses, curtailment, grid connection delays and supply chains concentrated in a few countries. Briefs here explain those effects alongside deployment data, and look at how pairing solar with storage changes its value. We rely on public data from agencies such as the EIA, IEA and IRENA, and flag where industry forecasts differ from what is actually being installed.
