February 28, 20215 yr Author Quote World Energy Outlook 2020 Solar becomes the new king of electricity… Renewables grow rapidly in all our scenarios, with solar at the centre of this new constellation of electricity generation technologies. Supportive policies and maturing technologies are enabling very cheap access to capital in leading markets. With sharp cost reductions over the past decade, solar PV is consistently cheaper than new coal- or gasfired power plants in most countries, and solar projects now offer some of the lowest cost electricity ever seen. In the STEPS, renewables meet 80% of the growth in global electricity demand to 2030. Hydropower remains the largest renewable source of electricity, but solar is the main driver of growth as it sets new records for deployment each year after 2022, followed by onshore and offshore wind. The advance of renewable sources of generation, and of solar in particular, as well as the contribution of nuclear power, is much stronger in the SDS and NZE2050. The pace of change in the electricity sector puts an additional premium on robust grids and other sources of flexibility, as well as reliable supplies of the critical minerals and metals that are vital to its secure transformation. Storage plays an increasingly vital role in ensuring the flexible operation of power systems, with India becoming the largest market for utility-scale battery storage. https://www.iea.org/reports/world-energy-outlook-2020 Edited February 28, 20215 yr by martin-w

Just done some checking, and discovered that some installers are as low as 5 years for the invertor in the UK too. 5 to 10 year warranty apparently. I would be seeking out the 10 years warranty for invertor and rest of the electronics. From what I understand, string invertors usually last ten years and cost around £500 to replace. Micro invertors are more expensive but last much longer on average. Nano coated salt technology above, looks VERY promising. https://saltxtechnology.com/technology/ Quote Thermo-chemical energy storage The energy is stored chemically, by separating salt from water, and then released by combining them again. This technology allows thermal energy to be stored and used hours, days, or months later. At scales ranging from individual processes to large scale storage for municipalities and cities. SaltX thermo-chemical energy storage can be charged with both electricity and heat and then be released as heat up to 450°C (900°F). Edited February 28, 20215 yr by martin-w
