How the world’s sunniest region tackles solar module soiling, cleaning
Researchers studying PV panels in Chile’s hyper-arid Atacama Desert found that cemented soiling can cause annual energy losses of up to 9.8%. Their combined field and laboratory work shows that dry cleaning leaves residue that accelerates future cementation, making wet cleaning the more effective long-term strategy despite higher costs and scarce water.
‘Back contact will reach cost parity with TOPCon before end of decade’
During a pv magazine Week Europe 2025 webinar, panelists forecast back contact (BC) solar cells’ market share will draw level with TOPCon towards the end of the decade, before tandem technology begins large-scale momentum in the early 2030s.
