Solar

Solar refers to energy technologies that harness sunlight to generate electricity or heat, forming a cornerstone of the global renewable energy transition. The two principal technologies are photovoltaic (PV) systems, which convert sunlight directly into electricity using semiconductor materials, and concentrated solar power (CSP), which uses mirrors or lenses to focus sunlight to produce heat for electricity generation. Solar PV has experienced rapid cost reductions and deployment growth over the past two decades, becoming one of the cheapest sources of new electricity generation in many markets. Utility-scale solar farms, rooftop installations and off-grid systems are deployed across residential, commercial and industrial applications. Solar energy is abundant, emissions-free during operation and increasingly competitive with fossil fuels, making it central to decarbonisation strategies and climate change mitigation. The technology requires critical minerals including silicon, silver, copper and increasingly cadmium, tellurium and indium for advanced thin-film panels. Africa has exceptional solar resources, particularly in the Sahel, southern Africa and East Africa, though deployment has lagged other regions due to financing, grid infrastructure and policy challenges. Solar complements wind power in diversified renewable energy portfolios and is often paired with battery storage to address intermittency. The sector is supported by policy mechanisms including feed-in tariffs, auctions and tax incentives, and is reshaping electricity markets, energy access and industrial competitiveness worldwide.

Grid capacity emerges as South Africa's critical solar bottleneck

South Africa has 72 GW of renewable energy projects at advanced stages and a 220 GW pipeline, yet the national grid lacks capacity to connect them, with most high-resource solar generation areas saturated, according to Energy Exchange South Africa CEO Wayne Cowie. The National Transmission Company South Africa has committed to adding about 14 450 km of new lines by 2034 to connect 56 GW of new capacity, but progress remains slow with just over 108 km completed as of October 2025 against a 2025/26 target of 423.1 km, while the South Africa Electricity Traders Association emphasises that new generation cannot connect without rapid grid expansion and strategic deployment of battery energy storage systems to manage intermittent renewables.

Stage Zero secures FirstRand securitisation for managed solar rollout

Renewable-energy company Stage Zero has concluded a securitisation transaction with FirstRand Bank to create a funding platform supporting the rollout of managed solar and backup systems for South African homes and businesses. The transaction allows Stage Zero to use the predictable revenue profile of its customer contracts to unlock institutional funding for further deployment, instead of relying solely on traditional project-by-project financing, with CEO Abraham van der Merwe noting that the structure reflects the maturity of distributed solar as an infrastructure model shaped by recurring revenues and managed assets.

Global solar generation expands 30% in 2025 as renewables overtake coal

Solar generation expanded by 30% worldwide in 2025, while battery capacity grew at 66%, with renewables and hydro overtaking coal as the largest source of electricity generation, the Energy Institute's Statistical Review of World Energy 2026 shows. Record global electricity demand was met entirely by low-carbon sources, with renewables growth of 861 TWh exceeding the absolute growth in electricity demand of 855 TWh, leading to a fall in fossil power generation.
