IRA-stimulated U.S. solar manufacturing capex to reach $12.2 billion by end 2026
A new report by Terawatt PV Research provides the first detailed bottom-up analysis of U.S. PV manufacturing sites, including capital expenditure, productivity and technology. The findings reveal that PV manufacturing capex since the introduction of the Inflation Reduction Act accounts for more than half of all investments in U.S. PV manufacturing this century.

Very low cost rooftop solar slashes domestic energy cost – Part 3: African Countries
There are 54 countries in the African Continent. Rooftop solar photovoltaics is growing rapidly in some African nations, but uptake is highly uneven across countries and is not measured comprehensively across all nations. It is clear that South Africa is far ahead of the rest of the continent (71% of all rooftop PV in Africa), while Nigeria, Kenya, Morocco and Egypt are emerging as important markets. Despite Africa’s abundant solar resources, a large gap persists between current rooftop solar deployment and its potential, largely due to low residential electricity tariffs and limited access to affordable financing.
