Technical FAQs 4

How effective are off-grid solar systems?

In 2022, off-grid solar systems served 490 million people globally, and projections suggest decentralized systems could account for 44% of new energy connections by 2030. One particularly effective approach is microgrid systems – off-grid solar networks made up of stand-alone units that when interconnected, form localized power grids.

Can off-grid solar improve climate resilience & economic development?

Renewable energy, including off-grid solar, can promote climate resilience and economic development and improve quality of life for all. By Simran Dali, Fátima Lunsford, and Duncan Wegner If we continue to produce emissions at current levels, we will lead ourselves towards irreversible atmospheric damage to our planet.

How many people benefit from off-grid solar?

As of 2023, off-grid solar solutions were estimated to benefit over 560 million people. Despite soaring inflation and extreme currency devaluations, among other factors, more than 50 million OGS products were sold in 2022 and 2023. Market turnover reached 3.9 billion USD in 2022 and 3.8 billion USD in 2023.

Is off-grid solar the most cost-effective way to power 41% of people?

Nairobi, 8 October 2024— Off-grid solar is the most cost-effective way to power 41% of people globally by 2030 who are still living without energy access. The sector already provided 55% of the new connections in sub-Saharan Africa between 2020 to 2022 - where over 80% of the unelectrified population lives.
