Dry August pushes Dallas soiling losses towards 2% as North American GHI diverges
In a new weekly update for pv magazine, Solcast, a DNV company, reports that August irradiance fell across the Great Lakes but rose across the Pacific Northwest, south-central United States, and Mexico amid contrasting weather patterns. Dry conditions pushed Dallas soiling losses toward a record 2%, while Hurricane Lala brought extreme rain to Hawaii but left monthly irradiance only 4% below normal.

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.

‘A modern economy runs on electricity’
Renewable energy, 24/7. Many still associate this with terms like “mammoth task,” “challenge,” and “radical change.” While these are not entirely inaccurate in describing the energy transition, they obscure the essential point that renewable energy actually presents a huge economic opportunity. As part of our Renewables 24/7 series, pv magazine spoke with German energy expert Tim Meyer about the many opportunities wrapped up in the energy transition, and why deployment of renewables at scale is now a necessary condition for the success of any advanced economy.

Spacebound silicon
Solar has a long history in powering satellites and space exploration, and high-powered devices based on multijunction PV cells made from “III-V” materials such as gallium arsenide or indium gallium phosphide have supplied this niche market as far back as the 1960s. But those devices are made with rare materials and complex processing, limited to small batches produced at high cost.
