A research team at DGIST in South Korea has unveiled an ingenious device that enhances solar power generation by keeping panels clean.

A research team at DGIST (Daegu Gyeongbuk Institute of Science and Technology) in South Korea has unveiled an ingenious device that enhances solar power generation by keeping panels free of dust and other contaminants. Harnessing wind power, this self-cleaning device autonomously maintains a vital component of the clean energy revolution.

The challenge of clean solar panels

Solar energy is vital for a sustainable future, but dust, debris, and other environmental contaminants can create a layer of grime that dramatically reduces solar cell efficiency. Traditionally, panels require manual cleaning, a costly and labor-intensive process. This maintenance is especially difficult in deserts, remote installations, and even potential off-world applications.

A French town is installing a canopy of solar panels over its cemetery that will distribute energy to local residents.

A French town is installing a canopy of solar panels over its cemetery that will distribute energy to local residents.

The idea didn’t start with solar. Saint-Joachim is located in the middle of the Brière marsh – a vast peat bog north of the Loire estuary.

When it outgrew its churchyard cemetery in 1970, a new graveyard was created to the east of the town’s main island, a drop from six to zero metres above sea level.

Upsettingly for families with loved ones buried there, that means the cemetery often floods in winter. Draining the ground would be a constant battle with the wetland, so Saint-Joachim’s mayor proposed covering the site to stop it from filling up with rainwater.

Under a newly announced federal grant, every household in the NW Arctic Borough would receive a heat pump and solar system in every village.

Under a newly announced federal grant, every household in the Northwest Arctic Borough would receive a heat pump to alleviate the cost of energy, and every village in the region would have a solar energy system — and an additional source of revenue.

In late February, the U.S. Department of Energy awarded rural and remote communities across the country funds to lower energy costs and support the deployment of clean energy. The Northwest Arctic Borough is receiving around $55 million, with grants funded by the 2021 federal infrastructure law. Counting all matches and contributions from regional partners, the total amount of funding for the four-year clean energy project is about $68.5 million, according to the statement from NANA Corp.

Solar workers traveled to the state capital on Wednesday to rally in support of solar energy, calling on lawmakers to keep CA a solar state.

Solar workers traveled to the state capital on Wednesday to rally in support of solar energy, calling on lawmakers to keep California a solar state.

The solar industry is experiencing business closures and significant job losses in every part of the state after the decision of the California Public Utilities Commission, or CPUC, to slash overnight by 70 to 80 percent the value of solar energy contributed back to the grid.

Since then, the solar industry has lost more than 17,000 jobs, representing 22 percent of all solar jobs in the state. A steep 87 percent decline in solar installations is also pushing California off its path to meeting renewable energy goals that are critical to the fight against climate change.

3 senior housing sites at Sage Lane have activated solar paired battery storage systems valued at $100,000 to power critical facility needs.

This Valentine’s Day, West Marin residents living in select affordable housing sites in San Geronimo will power up with more than just love from local partners – but with new battery storage and solar panels too.

Three senior housing sites at Sage Lane, owned by Two Valleys Community Land Trust, have activated solar paired battery storage systems valued at $100,000 to power critical facility needs. One of the sites without existing solar also received new solar panels.

MCE led the joint effort to fund the project with no out-of-pocket costs to the Land Trust. This includes a direct contribution of more than $36,000 from MCE, $32,000 from a Marin Community Foundation grant awarded to MCE, and $24,000 from the California Public Utilities Commission’s Self Generation Incentive Program, secured by MCE’s project partners.

The Edwards Sanborn Solar & Energy Storage project incorporates the highest capacity solar farm in the US with the largest battery storage system in the world.

Discussions of solar energy can be quick to point out its intermittent nature: the Sun does not always shine in any one place all the time. It does, however, shine quite a bit in the Mojave Desert in California. And as it happens, the Mojave is the location of a large new solar power plant integrated with battery storage. The Edwards Sanborn Solar and Energy Storage project incorporates the highest capacity solar farm in the United States with the largest battery storage system in the world.

The facility came online in February 2023 and became fully operational in January 2024. The OLI-2 (Operational Land Imager-2) on Landsat 9 captured this image of the project and its nearly 2 million solar panels on January 12, 2024. The site lies approximately 60 miles (100 kilometers) north of Los Angeles, in an area of the U.S. with some of the largest amounts of solar energy reaching the ground.

Many hands have been trying to make space solar happen for many years, and now the US Space Force may be helicoptering in to lend a hand.

The idea of beaming clean energy down to Earth from orbiting arrays of solar panels seemed pretty wacky when it first crossed the CleanTechnica radar. However, the technology building blocks are already at hand. It’s just a matter of scaling, systems integration, and adjustments for space-hardiness. That sounds simple enough, but many hands have been trying to make space solar happen for many years, and now the US Space Force may be helicoptering in to lend a hand.

The Space Solar Race Is For Real

Research teams from the US, China, and the UK are among those chasing the space solar rainbow. The attraction of space solar is the potential for 24/7 solar power at the multi-gigawatt scale, all year long. That has implications for military use as well as civilian life.

The US Department of Defense has already begun using solar arrays and energy storage to build more resilience and security into its facilities and operations. Access to solar energy from space would kick that effort into high gear.
