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...]
Solar “soiling”: energy loss from dust on panels can range from 7% to 50%
Dust and pollution particles on solar cells cut energy conversion, enough to cause big problems for investors let alone those depending on the generation. In parts of the U.S. energy loss can be as high as 7% and 50% in the Middle East. For assets supposed to deliver for 25 to 50 years this is hardly acceptable. Engineering solutions are struggling to keep up with the phenomenal take off of solar. Predicting the effects of “soiling” in your … [Read more...]
