Using electrostatic repulsion to clean Solar panels, avoiding up to 30% power loss

March 23, 2022 by David Chandler

Dust build-up on solar panels can reduce the power output by as much as 30% in just one month. Even a 1% reduction in power for a 150MW solar installation could result in a $200,000 (€180,000) loss in annual revenue. Cleaning normally requires purified water, but that needs to be trucked in to prime locations like deserts where solar potential is highest. Cleaning with brushes is labour intensive and can damage surfaces irreparably. David … [Read more...]

South Korea’s nuclear ambitions face safety, quality issues

May 9, 2019 by Dan Yurman

Dan Yurman summarises the regulatory, academic and press coverage of serious delays to South Korean nuclear reactors being built for the UAE. According to reports, these were caused by having to replace substandard components in reactors located in both South Korea and those planned for the UAE. There are problems with staff training too. South Korea recently completed the US NRC safety review process for its 1400 MW design. But the author asks … [Read more...]
